Perplexity and AI Powered Search

Generative AI is revolutionizing numerous industries. For Search, the traditional search engines are incorporating AI-generated answers alongside the paid and organic results. In parallel, we are seeing the emergence of AI-first search engines: innovative platforms designed to provide answers with citations generated by a large language model, differing from the conventional web index's link-based results.

These AI-first search engines are rapidly gaining popularity. Users highlight benefits such as an enhanced “conversational experience,” superior quality answers for certain inquiries, and ad-free responses.

As these innovative search engines attract more users, your website will begin receiving referrals from them. In the same way marketers mastered content optimization to get visibility in Google’s search results, we will embark on a comparable journey to fine-tune our content for visibility in these new engines’ citations.

At BrightEdge, our mission is to help marketers understand and make the most of all search platforms, both established and emerging. This guide serves as your introduction to Perplexity.ai, the leading AI-driven search engine, equipping you with the knowledge to understand the new “AI-first citation factors” and create content that excels across conventional and AI-first search engines alike.

Why is Perplexity Important for Digital Marketers?

Perplexity AI is reshaping the search industry with its revolutionary approach, marked by a staggering month-over-month growth rate of over 40%. As of early 2024, this innovative platform is capturing the attention of SEO experts and brands alike, driven by its unique method of delivering search results. Perplexity’s business model relies on premium subscriptions as opposed to advertising which could be a potential attraction for new users.

Perplexity has captured the interest of the SEO community as well. According to Google Trends, it really began capturing the interest of the public in December of 2023:

A recent survey by BrightEdge highlights the burgeoning interest among SEO professionals, with 17% of respondents from billion-dollar companies already exploring Perplexity's capabilities. When we asked this same question about SGE roughly last summer after its launch, only 5% indicated they were exploring it. The message is clear: to remain competitive, adapting SEO strategies to align with Perplexity's innovative indexing and content interpretation techniques is imperative.

While it remains to be seen whether users will use Perplexity alongside or in place of traditional search engines, the data unmistakably points to its significant early growth.

Why are people turning to Perplexity?

Building on the foundations of generative AI's role in search, Perplexity provides a refined search experience tailored to users who value directness and relevance. Although Perplexity has indicated it will offer an ad program, the platform is rooted in user intents which assuages concerns about sponsorship over substance in results.

The platform's interactive nature marks a departure from the traditional search experiences of the past. Perplexity engages users in an active dialogue, allowing for nuanced questions and in-depth exploration of topics in a conversational format. This modern approach aligns with the growing expectation for immediate, relevant responses.

For more sophisticated users, Perplexity's Pro version expands on these concepts. Incorporating documents and images into queries, it offers a bespoke summarization service, yielding responses that resonate more personally with the user's intent. These advanced features illustrate just one way in which Perplexity could be preferable to users who have turned to it.

Perplexity’s Advantages and Disadvantages

Query that Require Fresh Results

Perplexity AI combines the functions of a traditional search engine with the advanced capabilities of a Large Language Model (LLM) to offer direct and concise responses to queries. According to Perplexity, it prioritizes trustworthiness by sourcing its information from a select group of reputable sources rather than relying on an index as expansive as Google’s. Therefore, the pool of resources Perplexity AI utilizes to formulate answers is smaller when compared to Google's comprehensive index. This means that for certain queries, especially those requiring the latest content, Google may provide more current answers than Perplexity AI.

Perplexity’s User-Centric Approach

Perplexity stands apart from traditional engines by providing an ad-free environment that prioritizes user experience over ad revenue. This fundamental difference shapes aspects of its service. For example, users benefit from a customizable search journey, with innovative features like 'Your Threads' to save search interactions and a Copilot feature leveraging GPT-4 for interactive assistance, ensuring a seamless and personalized search process:

Unlike traditional search engines that might prioritize sponsored content, Perplexity's approach is user-centric, guiding individuals through specific questions to refine and tailor results. It deploys long-tail queries in dialogue with the user, resulting in highly personalized outcomes.

SEO Implications for Perplexity’s Interface:

• Optimize for Buyer Personas: Different buyers are searching for varied attributes. SEO teams must be familiar with the kinds of questions their target audience asks about products, as these will likely guide the AI's prompts and help refine the search queries.
• Establish Topical Credibility: Perplexity’s LLM and its sources are intentionally limited to those deemed trustworthy. While Perplexity does not disclose the sites in its index, it indicates through its blog that the index is updated daily. By analyzing which sites rank well and ensuring your site is cited by these, you can enhance your site’s chances of being considered trustworthy.
• Ensure Content is Current: Given that Perplexity relies on a more curated set of data compared to Google’s vast index, it is imperative that the sources display accurate and up-to-date information. This is a critical factor to consider in SEO planning for Perplexity.

How do Perplexity’s Sources Compare to Google SGE?

As noted, Perplexity distinguishes itself in its approach to generating search results by drawing on a pool of what it deems to be trusted sources. Utilizing the BrightEdge Generative Parser™ (BGP), we can discern the similarities and differences between the domains Perplexity uses to source its results and those used by Google SGE.

What Domains Are Sourced the Most?

The BrightEdge Generative Parser™ (BGP) has observed a noteworthy pattern of domain overlaps and exclusions between the citations from Google's Search Generative Experiences (SGE) and those used by Perplexity. Interestingly, four of the top-cited domains are consistent across both Google SGE and Perplexity, with a divergence observed in six others.

This guide features outputs from BGP that highlight the overlap between SGE and Perplexity. The domains shaded in orange represent the top 10 sources on both engines. Across all the keywords evaluated in all industries, this is where we see the most overlap:

Further scrutiny reveals a distinct visibility discrepancy:

• Domains such as yahoo.com, marketwatch.com, and cnbc.com are prominent within Perplexity, holding the second, third, and fourth positions, respectively.
• In stark contrast, their standings in Google SGE citations plummet to 95th, 434th, and 168th.
• This disparity underscores a significant divergence in citation prominence between the two entities.

The Rising Significance of Reddit in AI Search

Reddit's prominence within Perplexity's search environment is a key finding that merits emphasis. Ranking sixth in the BrightEdge Generative Parser's™ (BGP) Analysis, Reddit stands out as a central hub for information and discussion in all but two industries—Finance and Healthcare.

With Reddit's recent partnership with Google, aimed at enriching AI training methods with its vast content reservoir, we anticipate Reddit's influence to amplify within Perplexity and potentially influence Google's citation metrics.
This strategic alliance may enhance Reddit's weight within citation indices and bolster its domain authority across AI-enhanced search platforms. The role of strategic engagement on Reddit, especially through impactful comments, is becoming increasingly crucial. It not only aids in gaining traction within Perplexity's citations but also could serve as a lever to enhance visibility on broader platforms.

Industry experts are keenly observing this development, predicting that effective participation on Reddit could become a more significant factor in gaining prominence within AI-influenced search ecosystems.

SEO Implications for Top Domains in Perplexity

• Communities have authority - Actively manage and participate in Reddit communities related to your brand, as engagement on reddit.com may increasingly influence AI-powered search outcomes. Include monitoring discussions, reputation management, and keyword tracking on Reddit as integral components of your AI-Powered SEO strategy.
• Align with Experts - Keep knowledge-based content about your organization on leading platforms like MarketWatch and Yahoo Finance current and precise. Accuracy in these domains is crucial for maintaining credibility and visibility.
• Partnerships are Critical - For Original Equipment Manufacturers (OEMs), it's important to recognize that top retailers may play an amplified role on Perplexity. Ensure that product descriptions across these retail platforms are detailed, up-to-date, and accurate to enhance product visibility.

How to Prepare for Perplexity

As digital landscapes evolve, the emergence of AI-powered search engines like Perplexity presents a new frontier for digital marketers and SEO professionals. The key to mastering this domain is Generative Engine Optimization (GEO), a sophisticated approach to ensuring visibility in AI-driven search ecosystems. Perplexity's unique algorithmic preferences necessitate a tailored GEO strategy. Here's how to navigate this terrain:

Actionable Steps:

• Optimize for industry giants: TripAdvisor for travel, Yelp for restaurants, and Amazon for eCommerce, to name a few.
• Develop specialized content: Create industry-specific content that resonates with the themes of the favored platforms, be it travel guides or restaurant reviews.

• Invest in rich content: Beyond text, incorporate varied media like images and videos that align with Perplexity’s content preferences.

Foster Credibility and Trust

In industries like finance and insurance, Perplexity places significant weight on credible sources. Your GEO strategy must emphasize establishing trust through authoritative content and reliable information.

Actionable Steps:

• Highlight expertise: Showcase credentials, certifications, and expert opinions to build credibility.

How does my industry appear in Perplexity and SGE?

In our labs, BrightEdge has evaluated the industries most likely to feel the effects of SGE, results of which are detailed in our SearchQuake infographic. While Perplexity's impact seems less clear-cut than Google SGE, due to its established user base, we've identified domain overlaps between the two. This analysis sheds light on shared trusted sources and insights into the LLMs' preferences for sourcing information in both engines.

The accompanying chart provides a normalized index, ranging from one to ten, illustrating the domain overlaps for SGE and Perplexity. It focuses on domains that both platforms commonly source to answer queries related to these nine industries:

Exploring domain overlap across industries reveals strategic parallels and departures between Google SGE and Perplexity. In Healthcare and Education, both platforms similarly prioritize esteemed sites like mayoclinic.org and coursera.com, known for their authoritative content in their respective domains.

Divergence becomes apparent in the eCommerce and Finance sectors. While acknowledging the general importance of Wikipedia and Amazon, Perplexity distinguishes itself by valuing the communal insights of reddit.com for consumer perspectives, whereas Google opts for the expert-driven content of quora.com and consumerreports.org.

In Finance, Perplexity's preferences are starkly distinct, with a clear inclination towards yahoo.com and marketwatch.com, indicating a focus on timely market insights and comprehensive financial journalism.

The focus on Perplexity's strategic citation choices, particularly its use of reddit.com, highlights the platform's valuation of collective knowledge and user-contributed content. With the unfolding partnership between Google and Reddit, we might see Perplexity's citation patterns, especially its reliance on Reddit, start to sway or increasingly resonate with Google's own citation framework. This potential development points to a shift toward recognizing the significance of community-driven information in established citation practices.

SEO Implications for Industry Domain Overlap:

• Diverse Impact of Backlinks and Co-Citations: SGE and Perplexity each have their own set of high-authority domains they favor by industry. In Healthcare and Education, both platforms value trusted sources like mayoclinic.org and coursera.com, aligning SEO strategies with these domains can be effective. In contrast, for sectors like eCommerce and Finance, Perplexity shows a preference for domains such as reddit.com, yahoo.com, and marketwatch.com. SEO efforts should be adapted to these preferences, utilizing backlinks or co-citations to boost SEO performance.
• Tailored Strategies for AI-Powered Search: The approach to AI-powered search must be customized for each industry. Perplexity’s favor towards reddit.com highlights the value of community insights in eCommerce, while SGE prioritizes established review and Q&A sites like consumerreports.org and quora.com. Marketers and SEOs should devise content strategies that cater to these specific tendencies, like crafting detailed product reviews or fostering Q&A forums for eCommerce brands.
• Anticipating Citation Landscape Changes: SEO experts need to vigilantly track Perplexity’s favored domains, particularly its use of reddit.com for community-sourced content. With Google's partnership with Reddit, Perplexity may also modify its algorithm to further embrace Reddit’s content, a move that could signal an increased emphasis on content driven by user engagement. SEOs must stay ahead by being proactive and adaptable, ensuring their content strategy remains relevant and effective in light of Perplexity’s changing citation patterns.

In summary, SEO success on platforms like SGE and Perplexity hinges on a sophisticated strategy that considers each platform's distinct citation preferences and the specific demands of different industries. Staying attuned to the latest developments in digital partnerships and algorithm updates is also crucial. Such vigilance and adaptability are essential for SEO professionals striving to optimize their content's ranking effectively on these evolving platforms.

Industry Overlap Analysis

At a broader perspective, we note shared domain overlaps and that the degree of overlap between Perplexity and SGE varies by industry. These subtleties become more pronounced upon detailed examination of the data at the industry-specific level.

B2B Tech:

For digital marketers navigating the B2B tech industry, the alignment of domain citations between Google's Search Generative Experiences (SGE) and Perplexity offers valuable insights. The domains that overlap—techtarget.com, wikipedia.org, ibm.com, amazon.com, microsoft.com, google.com, and cloudflare.com—are pivotal players whose content is recognized as highly authoritative by both platforms.

Key takeaways for digital marketers in the B2B tech industry would include:

• Establish Long Term Credibility: Creating content or obtaining backlinks from these overlapping domains could boost SEO performance on both platforms, leveraging their established trust and authority within the industry.
• Syndicate for Quick Wins: Syndicating your content across these recognized platforms when possible may be an accelerated way to have your brand sourced as opposed to using your own domain.
• Balance the strategy: A balanced marketing strategy should be employed, taking into account the common ground in domain preferences. This means that while marketers should continue to focus on these authoritative sites, their long term goal should be to build authority on their own domains as competition for syndication space increases as AI-powered search proliferates among users.

By aligning strategies with the cited high-value domains, B2B tech marketers can ensure their content is positioned for optimal visibility and authority across both Google SGE and Perplexity.

E-Commerce:

For eCommerce SEO professionals and digital marketers, the data indicates a notable domain overlap between Google's Search Generative Experiences (SGE) and Perplexity: wikipedia.org. However, there's a distinct presence of amazon.com in Perplexity's citations, which isn't reflected in the Google SGE data shown.

Key takeaways for those in the eCommerce space:

• Prioritize Product Authority: Given Amazon's prevalence in Perplexity, marketers should ensure their products and services are well-represented on Amazon, either through seller or vendor central
• Leverage Reviews and User-Generated Content: Considering the importance of Amazon on Perplexity, reviews and user-generated content should be a cornerstone of eCommerce SEO strategies. Encouraging satisfied customers to leave positive reviews on Amazon could have a significant impact on search rankings within Perplexity.
• Promotion Adaptability: Since each platform may weigh content types differently, tailor promotions and ad content to the nuances of each search platform. For instance, focusing on informational content and brand authority for Google SGE, and user engagement and product listings for Perplexity.

Digital marketers and SEO teams working in eCommerce will need to be just as agile with AI-powered search as they are in traditional. However, in Generative Engine Optimization (GEO), this will require adapting their strategies to align with these key domains to optimize their content for discovery and authority in a competitive online marketplace.

Education:

For SEO professionals and digital marketers working in the Education sector, the data showcases a strong overlap in top domains between Google's Search Generative Experiences (SGE) and Perplexity, including coursera.org, indeed.com, usnews.com, snhu.edu, forbes.com, wikipedia.org, nu.edu, and bestcolleges.com.

Key takeaways for Education marketers:

• Capitalize on Common Ground: With significant overlap, ensure that your institution or educational platform is featured or has content on these shared top domains. This could improve visibility and authority across both search platforms.
• Course and Institution Listings: For domains like Coursera and US News, maintain up-to-date listings of courses and institutional rankings to leverage their SEO clout, which appears to be a common value for both SGE and Perplexity.
• Optimize Job Placement Content: With Indeed.com’s overlap, highlight your institution’s job placement success stories or career-related services, which could, through proxy, help your brand be more visible when Indeed is sourced.

By acknowledging these overlaps and focusing their SEO and content marketing strategies around these commonalities, education marketers can potentially increase their visibility and credibility on both Google SGE and Perplexity.

Finance:

In the finance sector, SEO experts and digital marketers should note the domain overlaps between Google's Search Generative Experiences (SGE) and Perplexity: investopedia.com, nerdwallet.com, and fool.com. As mentioned, there is less overlap in finance for top domains than many other industries analyzed. However, we do identify common threads between them that SEO’s and Digital Marketers can use to build their Generative Engine Optimization strategy.

Here are key takeaways:

• Capitalize on Credible Finance Resources: Domains like Investopedia and NerdWallet are trusted sources for financial information. Content partnerships or mentions on these sites can enhance credibility and SEO performance on both platforms.
• Leverage Current Financial News and Trends: CNBC’s presence in Perplexity suggests a preference for up-to-date financial news and market trends. Integrating current events into content can enhance visibility on this platform.
• Strategic Keyword Optimization: Utilizing keywords and phrases that align with the topics covered by these top domains can help in ranking better on both SGE and Perplexity due to the relevance in content matching.

For digital marketers in finance, aligning SEO and content strategies with the valued domains of both Google SGE and Perplexity is essential for improved search visibility and trustworthiness.

Healthcare:

In the healthcare sector, SEO and digital marketing professionals should take note of the overlap between Google's Search Generative Experiences (SGE) and Perplexity in recognizing mayoclinic.org, nih.gov, and medlineplus.gov as authoritative sources. This is notably where we observed the most overlap between Perplexity and SGE sources. In our SearchQuake Infographic, we also noted that, despite being a Your Money or Your Life (YMYL) category, healthcare is one of the most likely industries to be impacted by the rollout of SGE. Based on the current BGP data on Perplexity, it appears the LLM’s and algorithms associated with it are zeroing in on the same trusted sources as Google for addressing healthcare related queries.

Key SEO takeaways from this overlap:

• Establish Trust with Authoritative Sources: Incorporating content that aligns or gets recognized by these authoritative healthcare sites increases chances of being present in a sourced healthcare result in Perplexity. Reference and link back to these sites to leverage their domain authority to help your domain be included as a trusted source.
• Focus on Government and Institutional Domains: The presence of government (.gov) health domains in both lists highlights the importance of official and institutional information. Ensure content is backed by data from these sources to increase credibility.
• Update with Current Medical Research and Trends: Both platforms value domains that offer current medical information and research, like hopkinsmedicine.org on Perplexity and clevelandclinic.org on SGE. Staying current with medical trends and research can improve content relevance and authority.

For those in the healthcare digital marketing field, prioritizing content development strategies that focus on credibility, comprehensive information, and current research can enhance performance across both Google SGE and Perplexity.

Insurance:

For the insurance industry, the overlap between Google SGE and Perplexity indicates a shared recognition of forbes.com, www.gov.uk, indeed.com, and nidirect.gov.uk as key domains. Since insurance queries can involve financial information, it makes sense that AI powered engines would lean on sources that can be trusted to source answer content from. This will need to be a core part of any Generative Engine Optimization strategy in this space.

Here are the takeaways for insurance SEO experts and digital marketers:

• Government Sites as a Trust Signal: The presence of government-related sites like www.gov.uk and nidirect.gov.uk highlights the importance of recognized authority and trust signals in content, which is critical in an industry based on trust like insurance.
• Employment Opportunities and Education: The citation of indeed.com suggests a demand for content that connects employment opportunities and insurance, perhaps educational content on insurance careers or industry trends that could be valuable to users.
• Localized SEO: Nidirect.gov.uk's presence implies the value of localized content for regional markets, indicating that SEO strategies should consider geographical relevance, especially for local insurance services.

Digital marketers in the insurance industry should craft their SEO and content strategies to capitalize on the trust and authority associated with these shared domains, while also recognizing the importance of localized and employment-related content.

Restaurants:

In the restaurant industry, there is a clear overlap in domain citations between Google SGE and Perplexity, highlighting yelp.com, tripadvisor.com, wikipedia.org, opentable.com, eater.com, and grubhub.com as significant players. With the industry’s inherent focus on local intent, we are seeing this reflected in how AI powered search is addressing queries. As with traditional search, this needs to be factored in to how Generative Engine Optimization is approached.

Key insights for restaurant SEO professionals and digital marketers are:

• Utilize Popular Review and Booking Platforms: Yelp and TripAdvisor's presence across both platforms underscores their importance for visibility. Ensuring that restaurants have a strong presence and positive reviews on these sites is essential.
• Content Richness and Diversity: Wikipedia’s citation suggests that having comprehensive and well-maintained Wikipedia pages can be beneficial. It also implies the importance of content diversity—from menus and services to the history of the establishment.
• Engage with Food Communities: Eater.com’s inclusion indicates that engagement with niche food communities and content platforms can be advantageous for reaching dedicated food enthusiasts.

By aligning their online strategies with the valued domains recognized by both search engines, restaurant marketers can optimize their visibility and attract more customers through AI Powered search.

Travel:

For travel SEO experts and digital marketers, the overlapping domains between Google SGE and Perplexity are tripadvisor.com, expedia.com, yelp.com, kayak.com, hotels.com, and booking.com. These sites are transactional in nature, in the sense that their primary purpose is for users to book something. Similar to Restaurants leaning on local, this suggests that AI Powered search is leaning heavily on that intent in the travel space. SEO’s and marketers in the travel space should expect that AI powered search will likely expand down the funnel. This needs to inform the Generative Engine Optimization strategy employed in this industry.

Key takeaways for Travel SEO and Digital Marketing:

• Maximize Presence on Travel Aggregators: The repeated appearance of TripAdvisor, Expedia, Kayak, Hotels.com, and Booking.com signals the high value of these platforms for visibility. Optimize listings and leverage these aggregators for maximum reach.
• Optimized Booking Experience: The prominence of booking platforms suggests that seamless booking experiences are crucial. Ensure that the booking process on your site is streamlined and user-friendly.
• Comprehensive Content Strategy: Use comprehensive content strategies that include destination guides, travel tips, and reviews to align with the content-rich nature of the cited domains.

Travel marketers should ensure that their SEO and content strategies capitalize on the strong search presence of these key travel domains across both Google SGE and Perplexity to remain competitive.

Conclusion

Preparing for Perplexity means embracing the nuances of Generative Engine Optimization, with a keen understanding of domain authority, industry-specific platforms, and the evolving landscape of AI partnerships. By integrating these principles into your digital marketing and SEO strategies, you’ll be well-positioned to capture the attention of both Perplexity's algorithms and the audiences they serve.
