They are algorithmically selected — you cannot request them. You earn them through structural clarity.\n\nSource: Bill Slawski's SEO by the Sea — Search UI Features and Rich Results (56 articles analyzing Google's sitelink patents).\n\n## Core Principles\n\n1. **Hierarchy is a signal**: Google reads your site architecture as a declaration of importance. Ambiguous hierarchy = no sitelinks.\n\n2. **Internal links are votes**: Every internal link to a page is a weighted vote. Concentrated votes on 6-8 key pages amplify the signal.\n\n3. **Brand search is the trigger**: Sitelinks appear almost exclusively for brand/navigational queries. No brand search volume = sitelinks are irrelevant.\n\n4. **Titles are the display layer**: Sitelinks show page titles as clickable links. Duplicate, vague, or overly long titles kill sitelink quality even when structure is perfect.\n\n5. **User behavior validates structure**: Google uses click data to confirm or override structural signals.\n\n## The 8-Point Sitelink Readiness Audit\n\n### 1. Site Hierarchy Clarity\n\nFor sitelinks to appear, Google must clearly identify 4-6 pages that represent the site's most important sections.\n\nCheck:\n- Are top-level pages (1 click from homepage) clearly categorical? (Services, About, Contact, Blog)\n- Do these top-level pages have distinct purposes that don't overlap?\n- Is the navigation consistent across all pages?\n\n### 2. Internal Link Concentration\n\nMap inbound internal link count for each page. Sitelinks typically emerge from the 6-8 pages with the highest internal link concentration.\n\nIf the top 6 pages by internal link count are not the pages you want as sitelinks, restructure internal linking.\n\n### 3. Brand Search Volume\n\nSitelinks only appear for brand queries. Check GSC for impressions on branded queries (your business name + variations). If branded impressions are under 1,000/month, sitelinks are unlikely regardless of site structure.\n\n### 4. Title Tag Differentiation\n\nReview page titles for the top 6-8 candidate sitelink pages:\n- Is each title unique?\n- Is each title under 50 characters?\n- Does each title clearly describe what makes that page different from the others?\n- Are titles format-consistent (all title case, or all sentence case)?\n\n### 5. Homepage Disambiguation\n\nThe homepage must clearly establish what the site is about. Google uses the homepage title and H1 to determine the entity's primary identity.\n\n- Homepage title: [Brand Name] — [Primary Service/Category] in [City]\n- Homepage H1: matching or slightly expanded\n\n### 6. Navigation Architecture\n\nSitelinks often mirror the main navigation. Review:\n- Primary nav contains 4-6 items (not 12)\n- Nav labels match page titles (or are subsets)\n- Nav is HTML text links (not JavaScript-rendered)\n- Mobile nav identical to desktop nav\n\n### 7. Sitelink Search Box Implementation\n\nFor sites with meaningful on-site search, implement Sitelink Search Box schema (WebSite type with `potentialAction`):\n\n```json\n{\n  \"@context\": \"https://schema.org\",\n  \"@type\": \"WebSite\",\n  \"url\": \"https://example.com\",\n  \"potentialAction\": {\n    \"@type\": \"SearchAction\",\n    \"target\": {\n      \"@type\": \"EntryPoint\",\n      \"urlTemplate\": \"https://example.com/search?q={search_term_string}\"\n    },\n    \"query-input\": \"required name=search_term_string\"\n  }\n}\n```\n\n### 8. Click Validation\n\nFor sites that already have partial sitelinks, GSC shows which pages appear. Pages with high click-through from sitelinks will be retained. Pages with low CTR may be swapped out.\n\nMonitor: GSC → Search Results → filter for branded queries → check which pages appear.\n\n## Anti-Patterns That Prevent Sitelinks\n\n- Over 8 items in primary navigation (dilutes vote concentration)\n- Duplicate or similar page titles (Google cannot differentiate sitelink candidates)\n- Homepage with no clear brand + primary category declaration\n- JavaScript-only navigation (reduced crawlability)\n- No brand search volume (the trigger query doesn't exist)\n\n## Cross-References\n\n- `internal-linking-optimizer` — internal link concentration strategy\n- `schema-generator` — WebSite schema for Sitelink Search Box\n- `entity-seo` — brand entity signals that support brand search volume\n\n#seo-sop #seo #sitelinks #site-architecture #ctr #brand-search\n","html":"<h2>What Sitelinks Are</h2>\n<p>Sitelinks are the 2-6 sub-links that appear beneath a brand's main search result for navigational queries.
