This update, rolled out on June 6, 2019, aimed to limit multiple listings from the same domain in top search results, promoting a wider variety of websites. By doing so, Google sought to enhance user experience by offering diverse perspectives and giving smaller websites a chance to compete against dominant players.

What Is the Site Diversity Update?
The Site Diversity Update is a Google algorithm change designed to prevent any single domain from dominating the top search results. Before this update, it was common for large, authoritative websites to occupy multiple spots in the top 10 results for a given query. This often left little room for smaller or niche websites to gain visibility. The update, announced via Google’s official channels, aimed to cap the number of listings from the same domain to typically no more than two in the top results, though exceptions could apply for highly relevant queries.
This change aligns with Google’s mission to deliver diverse, relevant, and high-quality results to users. By reducing domain crowding, the update ensures users see a broader range of sources, fostering a more inclusive digital ecosystem.
Why Did Google Introduce This Update?
Google’s primary goal is to provide users with the most relevant and diverse information possible. Before the Site Diversity Update, certain queries—especially broad or informational ones—often resulted in SERPs dominated by a single domain. For example, a search for “best laptops” might have shown multiple pages from a single tech review site. This limited the variety of perspectives users could access.
Here are the key reasons Google implemented the update:
- Enhance user experience: Diverse results provide users with varied viewpoints and sources.
- Promote fairness: Smaller websites get a better chance to rank alongside larger competitors.
- Reduce redundancy: Multiple listings from one domain often provided similar information, cluttering the SERP.
- Align with E-A-T principles: By showcasing diverse sources, Google reinforces its focus on Expertise, Authoritativeness, and Trustworthiness.
How the Update Works
The Site Diversity Update modifies how Google’s algorithm evaluates and ranks web pages. While Google has not shared the exact mechanics of the update (as is typical with its algorithm changes), the core principle is straightforward: limit the number of times a single domain appears in the top results for a given query. Typically, Google now restricts a domain to two listings in the top 10, though this can vary based on query intent or relevance.
For example:
- If a user searches for “SEO tips,” a single domain like a major marketing blog might previously have had three or four pages in the top results. Post-update, only two pages from that domain would typically appear.
- For highly specific queries, such as a branded search (e.g., “Nike running shoes”), Google may allow more listings from the same domain if they are deemed uniquely relevant.
The update primarily affects organic search results but does not directly impact paid ads or featured snippets. It relies on Google’s understanding of domain relationships, ensuring that subdomains or sister sites are treated as part of the same entity when appropriate.
Impact on Smaller Websites
The Site Diversity Update was a boon for smaller websites and niche content creators. By reducing the dominance of large domains, the update opened up opportunities for lesser-known sites to gain visibility. Here’s how smaller sites benefited:
- Increased visibility: Smaller sites now have a better chance to rank in the top results, even for competitive keywords.
- Level playing field: The update reduced the advantage of large domains with extensive backlink profiles or brand recognition.
- Encouraged niche content: Specialized websites focusing on specific topics could compete more effectively.
For instance, a small blog about sustainable fashion could now rank alongside major retailers for queries like “eco-friendly clothing,” provided it offers high-quality, relevant content.
Effects on Large Domains
While the update benefited smaller sites, it posed challenges for larger domains that previously dominated SERPs. Major players like news outlets, e-commerce giants, and content aggregators saw a reduction in their top-ranking pages. The effects included:
- Fewer top positions: Large domains could no longer occupy multiple spots for broad queries.
- Increased competition: Dominant sites now compete with a wider range of sources, including smaller competitors.
- Shift in SEO strategies: Large websites had to rethink how they optimized content to maintain visibility.
For example, a major tech site might have lost some top rankings for generic queries like “smartphone reviews” but could still dominate for branded or highly specific searches.
SEO Strategies Post-Update
The Site Diversity Update forced website owners and SEO professionals to adapt their strategies. To thrive in this new landscape, businesses and content creators needed to focus on quality, relevance, and user-centric content. Here are key strategies to succeed post-update:
- Create high-quality content: Content that demonstrates Expertise, Authoritativeness, and Trustworthiness remains critical. Ensure all information is accurate and well-researched.
- Target long-tail keywords: Smaller sites can gain traction by focusing on specific, less competitive keywords.
- Optimize for user intent: Understand what users are searching for and tailor content to meet their needs.
- Improve site structure: Ensure your website is easy to navigate, with clear internal linking and a logical hierarchy.
- Build diverse backlinks: Earn links from a variety of reputable sources to boost authority.
By focusing on these strategies, websites can align with Google’s goals and improve their chances of ranking well.
Comparing Site Diversity to Other Updates
The Site Diversity Update is one of many algorithm changes Google has implemented to improve search quality. To understand its significance, let’s compare it to other notable updates:
| Update | Year | Purpose | Impact |
|---|---|---|---|
| Panda | 2011 | Target low-quality content | Penalized thin or duplicate content, rewarding high-quality sites |
| Penguin | 2012 | Combat spammy link-building | Reduced rankings for sites with unnatural backlinks |
| RankBrain | 2015 | Improve query understanding | Enhanced relevance for complex or ambiguous searches |
| Site Diversity | 2019 | Limit domain dominance | Promoted variety in SERPs, benefiting smaller sites |
Unlike Panda or Penguin, which targeted specific SEO abuses, the Site Diversity Update focused on improving the overall user experience by diversifying results. It complemented Google’s ongoing efforts to prioritize E-A-T and deliver value to users.
Challenges and Criticisms
While the Site Diversity Update was largely well-received, it wasn’t without challenges. Some criticisms included:
- Limited transparency: Google provided minimal details about how the update determines which domains get capped.
- Impact on authoritative sites: Some argued that highly trusted domains deserved multiple spots due to their reliability.
- Potential for lower-quality results: In some cases, less authoritative sites ranked higher, raising concerns about content quality.
Despite these challenges, the update’s benefits—such as increased fairness and variety—outweighed the drawbacks for most users.
How to Adapt to the Update
To succeed in the post-Site Diversity Update era, website owners must focus on creating valuable, user-focused content. Here are practical steps to adapt:
- Audit your content: Ensure all pages are unique, informative, and aligned with user intent.
- Optimize for E-A-T: Showcase expertise by including author bios, citing credible sources, and maintaining a professional site design.
- Monitor rankings: Use tools like Google Search Console to track changes in your site’s performance.
- Diversify content formats: Experiment with videos, infographics, or podcasts to engage users and stand out.
- Engage with your audience: Respond to comments and feedback to build trust and loyalty.
By prioritizing quality and user experience, websites can thrive in a more diverse search landscape.
Future Implications for Search
The Site Diversity Update is a stepping stone toward a more inclusive and user-centric search ecosystem. As Google continues to refine its algorithm, we can expect further emphasis on diversity, relevance, and quality. Future updates may build on this foundation by:
- Enhancing AI-driven ranking: Tools like RankBrain and BERT will likely play a larger role in understanding user intent.
- Prioritizing local and niche content: Smaller businesses and creators may gain even more visibility.
- Balancing authority and variety: Google may refine how it balances trusted domains with diverse sources.
For now, the Site Diversity Update serves as a reminder that Google values fairness and variety in its search results. By creating high-quality, user-focused content, website owners can align with these goals and succeed in an ever-evolving digital landscape.
