    Links & Authority: how relevance and trust flow through your pages

    Links are the web's nervous system. Internal links route authority and signal topical relationships between your pages; outbound links to credible sources signal that your content is well-grounded; and broken links quietly leak both trust and crawl budget. Engines — and AI — read all of it.

    This category is about connections. Descriptive anchor text labels what each link points to; outbound links to credible sources signal grounded, trustworthy content; and broken links are a maintenance signal that erodes both. Link depth decides how reliably your important pages get crawled. AI engines use this link context to understand topical relationships and to gauge how well-supported your claims are.

    Each check has a stable ID (F1–F5).

    In short: Internal links should use descriptive anchor text — "GEO readiness checklist", not "click here". Descriptive anchors pass a topical signal to the linked page and tell users (and screen readers) where the link leads.

    Anchor text is the visible, clickable words of a link, and it acts as a human-written label for the destination. Engines use it as a signal of what the linked page is about, so a descriptive anchor passes useful relevance to the target page — while "click here" or "read more" passes nothing.

    For internal links you control every anchor, so describing the destination is an easy, high-value habit. Vary the phrasing naturally — repeating identical, keyword-rich anchors looks manipulative.

    Descriptive anchors are also an accessibility win for screen-reader users, who often navigate by a list of link text alone.

    Pass: Internal links mostly use descriptive anchor text.
    Warning: Several links use generic, non-descriptive anchors.
    Fail: Most anchors are generic like "click here".
    In short: Internal links should resolve to live pages. Broken internal links waste crawl budget, frustrate users, and break the flow of authority through your site.

    A broken internal link sends users and crawlers to a dead end. For crawlers it wastes crawl budget; for users it's a frustrating 404. And it interrupts the flow of authority and discovery that internal links are supposed to provide.

    Broken links accumulate naturally as pages are removed or URLs change without redirects. The remedy is periodic auditing: find them with a crawl, then fix, redirect or remove each one.

    Pass: No broken internal links found.
    Warning: A few internal links return errors.
    Fail: Many internal links are broken.
    In short: Outbound links should still resolve. Dead external links (link rot) send users to dead ends and weaken the credibility of the sources you cite.

    External links decay over time — the pages you cited get moved, restructured or deleted, leaving dead references on your page. Link rot is unavoidable but fixable with periodic checking.

    Broken outbound links damage trust, undercut the credibility your citations were meant to provide, and signal stale, unmaintained content. Update each dead link to a current source, point it at an archived copy, or remove it.

    Pass: No broken outbound links found.
    Warning: A few outbound links are dead.
    Fail: Many outbound links no longer resolve.
    In short: Link out to credible, authoritative sources where it helps. Citing reputable references backs up your claims and signals well-researched content — a trust cue both search and AI engines reward.

    Linking to authoritative external sources — peer-reviewed studies, official documentation, recognised publications — backs up your claims and shows your content is grounded in evidence rather than asserted in a vacuum. It's a quiet quality signal that supports the expertise and trustworthiness pillars of E-E-A-T.

    Contrary to an old myth, linking out doesn't "leak" authority; citing good sources is a normal feature of credible content that engines understand. Link to genuinely authoritative, on-topic sources — not weak or tangential ones.

    For GEO this matters extra: AI answer engines themselves cite trustworthy sources, and well-sourced content looks more like something worth citing in turn.

    Pass: The page cites credible external sources.
    Warning: Few or weak external references.
    Fail: No external sources cited.
    In short: Important pages should be reachable within a few clicks of the homepage. Pages buried more than ~3 clicks deep get crawled less and treated as less important.

    Click depth is the fewest clicks needed to reach a page from the homepage. Pages close to the homepage inherit more authority and get crawled more often; pages buried many levels deep are discovered slowly and can be effectively neglected.

    Keep priority content shallow via clear navigation, category hubs and related-content links. A flat, well-linked architecture beats a deep, nested one for both crawl efficiency and authority distribution.

    Pass: The page is 3 clicks or fewer from the homepage.
    Warning: The page is 4–5 clicks from the homepage.
    Fail: The page is more than 5 clicks deep and rarely crawled.

    Why links & authority matter for SEO and GEO

    Links are how the web expresses relationships and trust, and engines have read them that way for decades. Internally, your link graph decides which pages accumulate authority and how easily everything gets discovered — a great page that nothing links to barely exists. Externally, who you cite (and how) signals how well-grounded your content is.

    For GEO, the link context is part of how an answer engine understands your topical relationships and judges whether your claims are supported. Descriptive anchors label your relationships clearly; outbound citations mark your content as grounded; and broken links quietly undercut both. None of it is glamorous, but a clean, intentional link structure is foundational to how authority flows and how engines read your site.

    The AI-era twist

    AI engines treat outbound citations the way a careful editor does — as evidence that a claim is grounded. Content that links to credible sources reads as trustworthy and is more likely to be cited; content full of unsupported assertions or spammy links is routed around. And because internal links define your topical relationships, they help an answer engine understand which of your pages is the authoritative one on a given subject — a core part of GEO / LLM readiness.

    FAQ

    Anchor text — the clickable words — is a human-written label that tells engines and AI what the linked page is about. "Our GEO audit checklist" is informative; "click here" conveys nothing. Use natural, descriptive anchors (without repeating identical exact-match phrases everywhere, which looks manipulative). It's also an accessibility win for screen-reader users.
