How does Google choose which sitelinks to display under your search results?

What triggers the appearance of sitelinks under a result?

Sitelinks are those secondary links displayed under certain search results, usually on brand or navigational queries. Google automatically generates them when it believes they can help users access a specific section of the site more quickly.

Mueller emphasizes the automatic nature of the process — there is no magic tag to add, no form to fill out. The algorithm scans the site's structure, analyzes internal links, evaluates the relative popularity of pages, and decides which links to display. If your architecture is opaque or inconsistent, Google will struggle to identify priority pages.

Why is the site's hierarchy so crucial?

A clear hierarchical structure means that Google can quickly distinguish main pages from subpages and understand the relationships between them. Specifically: a "Services" page with subpages "SEO", "Web Design", "Advertising" is more readable than a flat menu with 30 links at the same level.

Internal linking plays a major role. Pages linked from the main menu, footer, or recurring sections receive more hierarchical weight. Google interprets these signals as indicators of importance. If a page is buried 5 clicks from the home page and does not appear anywhere else, it will never be a candidate for a sitelink.

Can Google make mistakes in choosing sitelinks?

Yes, and it happens frequently. Google bases its decision on algorithmic data that does not always reflect the business logic of the site. A legal notice page might appear as a sitelink if it is too prominent in internal linking, while a strategic landing page remains invisible.

The old Search Console allowed for the manual removal of certain sitelinks. This functionality is gone. Today, the only way to correct an unwanted sitelink is to modify the site's architecture — reduce the visibility of the relevant page, strengthen links to priority pages, clarify the structure.

• Sitelinks are generated automatically by the algorithm, with no possible manual intervention
• The clarity of the hierarchy (main pages vs subpages) is the determining factor
• Internal linking must reflect the strategic importance of the pages
• Google can display irrelevant sitelinks if the structure is ambiguous
• Correction involves a redesign of the architecture, not a form or tag

Does this statement align with field observations?

Overall, yes. Sites with a clear silo structure and logical internal linking do indeed display more relevant sitelinks. Well-structured e-commerce sites (categories > subcategories > products) often benefit from coherent sitelinks, while cluttered sites with overloaded menus yield random results.

However, Mueller remains vague about the popularity criteria. Google does not solely rely on hierarchy — it also analyzes the click-through rate on internal links, the time spent on each page, and associated queries. A page might be structurally secondary but become a sitelink if users access it en masse. [To be verified]: Google has never officially confirmed the use of these metrics for sitelinks.

What nuances should be added to this recommendation?

The size of the site changes the game. On a 20-page site, structure is rarely an issue. On a 10,000-page site, even a clean hierarchy can produce disappointing sitelinks if the internal linking is poorly calibrated or if certain pages accumulate disproportionate internal PageRank.

Another point: sitelinks evolve. A page can appear and then disappear depending on algorithm updates or site changes. I've seen cases where a simple menu change caused a strategic sitelink to disappear, replaced by a less relevant page. Google reacts to structural changes, but not always in the expected direction.

When does this rule not suffice?

If the site uses heavy JavaScript to generate navigation, Google may struggle to interpret the hierarchy, even if it is logically clear for a human. AJAX menus without HTML fallback are particularly problematic. The structure must be crawlable, not just visible.

Multilingual or multi-regional sites also pose challenges. Google may mix sitelinks from different language versions, especially if hreflang tags are poorly implemented. Structural clarity in French does not prevent an English sitelink from appearing if the algorithm detects geographical ambiguity.

What concrete steps should be taken to optimize sitelinks?

Start with an audit of the current structure. Export your site's hierarchy, identify the levels of depth, and spot orphaned or poorly linked pages. A tool like Screaming Frog or Sitebulb is sufficient. The goal: to ensure that strategic pages are accessible in a maximum of 2-3 clicks from the home page.

Next, revise your internal linking. Pages you want to appear as sitelinks should be linked from recurring areas (main menu, footer, sidebar) with explicit anchors. If "Our Services" deserves a sitelink, make sure it appears in the menu and that contextual links from other pages point to it.

What mistakes should be avoided during a structure overhaul?

Do not multiply hierarchical levels unnecessarily. A structure of Home > Category > Subcategory > Sub-subcategory > Page dilutes the signal. Google loses the thread. Aim for simplicity: 3 levels are sufficient in 90% of cases.

Avoid long menus with 40 links at the same level. Google will interpret all these links as equivalent in importance, which muddles the hierarchy. If you must display many links, structure them into submenus or distinct sections. A well-organized mega-menu is preferable to an endless flat list.

How can I check if Google understands my site's structure correctly?

Observe the sitelinks displayed for a brand query. If you see coherent pages (Home, Products, Contact, About), that's a good sign. If secondary pages (T&Cs, Sitemap, obsolete pages) appear, it indicates that the hierarchy is being misinterpreted.

Also, use the Search Console to identify the most crawled pages and those that receive the most impressions. Cross-reference this data with your ideal structure. If a strategic page is poorly crawled, strengthen its internal linking. If a secondary page is over-crawled, reduce its visibility.

• Audit the current hierarchy and identify pages at 4+ clicks deep
• Strengthen internal links to strategic pages (menu, footer, contextual links)
• Simplify the structure: aim for a maximum of 3 hierarchical levels
• Clean up overloaded menus and organize links into logical submenus
• Check the crawl in Search Console and correct underrepresented pages
• Test the display of sitelinks on brand queries after each modification
