How does Google decide to show multiple results from the same site in its SERPs?

Why did Google abandon the strict limit of two results per domain?

For years, Google applied an unwritten rule: a maximum of two results from the same domain on the first page. This constraint has been gradually relaxed. The search engine now acknowledges that exceptional relevance can justify more than two positions for a single site.

This change reflects an evolution in Google's paradigm. Rather than imposing an arbitrary limit, the algorithm now assesses whether the marginal utility of an additional result from the same domain exceeds that of a result from another site. This approach assumes that some sites concentrate enough expertise that their temporary monopoly better serves the search intent.

In what concrete cases do we observe this increase in results?

Very specific or technical queries often trigger this phenomenon. For example, a search for "advanced settings Photoshop CS6" may display three or four pages from the official Adobe site if it thoroughly covers the topic. Official brand sites, technical documentation, and knowledge bases frequently benefit from this treatment.

Navigational queries also amplify the effect. A search for "Nike air max" will naturally return multiple pages from Nike.com: category page, product sheets, thematic landing pages. Google interprets the intent as a desire to access the Nike universe, rather than to compare with Adidas.

How does Google arbitrate between relevance and diversity?

The statement remains vague on specific thresholds. Google mentions a "balance" without quantifying what constitutes an "excessive harm" to diversity. In practice, we rarely observe more than four results from the same domain on the first page, except in extreme cases (brand queries, pure navigation).

The algorithm seems to apply a growing marginal cost to each additional result from the same site. The first result simply needs to be relevant. The second must provide distinct value. The third and beyond require significantly higher relevance than alternatives from other domains to justify their inclusion.

• Exceptional relevance: A site can occupy multiple positions if its authority and coverage of the topic vastly exceed the competition
• Diversity preserved: Google avoids allowing a single domain to monopolize the entire first page, except for brand queries or purely navigational requests
• Dynamic assessment: The number of allowed results varies according to the query, the detected intent, and the comparative quality of available alternatives
• No rigid limit: The rule of a maximum of two results no longer formally exists, replaced by contextual arbitration
• User intent: Navigational or brand queries naturally favor the concentration of results on the target site

Is this statement consistent with field observations?

Overall yes, but with important nuances. Tests do indeed show greater flexibility in recent years. On technical niche queries, we regularly see three results from the same authoritative domain. Documentation sites (GitHub, Stack Overflow, MDN) frequently hold multiple positions on developer queries.

The problem? Google remains exceptionally vague about the triggering criteria. "Adding value" and "without excessive harm" are statements that provide no concrete insights. [To check]: impossible to know at what comparative quality threshold a site surpasses two results, nor what metric Google uses to measure "harm to diversity".

What are the weaknesses of this communication?

The first point: Google presents this mechanism as a favor granted to quality sites, but completely overlooks cases where this concentration objectively harms the user. On certain commercial queries, seeing four results from Amazon when specialized shops offer better expertise does not always enhance the experience.

The second flaw: the notion of "diversity" remains a vague marketing concept. Diversity of domains? Editorial angles? Types of content? Google never clarifies. In practice, we find that diversity of domains takes precedence, but that within a single domain, diversity of angles is rarely a blocking criterion for displaying several similar results.

In what cases does this rule not really apply?

Broad informational queries maintain strict diversity. Search for "how to lose weight": you will never see three results from the same health blog, even if it is excellent. Google prioritizes contrasting different approaches on subjects where consensus does not exist or where multiple methodologies co-exist.

YMYL topics (Your Money Your Life) also seem subjected to a reinforced diversity constraint. On medical or financial queries, Google deliberately limits concentration to prevent a single source, even if reliable, from dominating the discourse. Editorial responsibility then takes precedence over pure algorithmic relevance.

How can you optimize your site to capture multiple positions for the same query?

First step: structure your information architecture to cover different angles of the same topic. If you target "CRM for small businesses", create a general pillar page, specific feature pages (mobile CRM, free CRM, French CRM), and comparisons. Each page should address a distinct micro-intent while remaining consistent with the main query.

Second lever: maximize the semantic differentiation between your pages. Google will not display three variations of the same content. Each URL must bring a different angle, format, or depth. A comprehensive guide page + a FAQ page + a checklist page are more likely to coexist than a duplicate generic page three times with marginal variations.

What mistakes should you avoid to not cannibalize your own positions?

The classic mistake: creating nearly identical landing pages targeting the same query with artificial geographical or categorical variations. Google detects this duplication and will show only one version, or none if it resembles manipulation. Internal cannibalization remains your number one enemy.

Another trap: multiplying weak pages instead of concentrating authority. It is better to have two excellent and complementary pages than one strong page and four mediocre ones. If your site does not yet have sufficient authority, focus on creating an exceptional pillar page before deploying thematic satellites. Multiplication only works if each new page reaches a high absolute quality threshold.

How can you measure if your multi-results strategy is working?

Use the Search Console to identify queries where you already appear multiple times. Filter by query and count the number of distinct URLs ranked in the top 20. These queries are your natural candidates for pushing a third or fourth position. Analyze what differentiates your already ranked pages to reproduce this complementarity.

Also monitor the aggregated CTR on these queries. If you occupy positions 3, 7, and 12, your cumulative CTR may exceed that of a competitor alone in position 1. This is an indicator that your coverage strategy is working. Conversely, if your multiple positions cannibalize your CTR without gaining overall traffic, it means Google is displaying you by default, not by excellence.

• Map your pages according to the micro-intents they serve, not just by keywords
• Ensure that each page aiming for multiple rankings achieves a E-E-A-T quality level comparable to your best page
• Avoid content duplication and cosmetic variations: differentiation must be substantial and visible to the algorithm
• Prefer complementary formats (long-form guide + video + interactive tool) rather than three similar articles
• Measure the impact in overall traffic on the target query, not only in the number of positions occupied
• Test first on specific niche queries where your authority is established before aiming for broad competitive queries
