Internal links missing from raw HTML: a link graph Google discovers late

In brief

Your internal links (menu, footer, navigation) are injected by JavaScript and absent from the raw HTML: Google discovers them more slowly and AI systems that read raw HTML do not navigate your site. Render navigation server-side, with real a href tags.

What is it?

The page's internal links are injected by JavaScript, absent from the raw HTML.

Why it hurts SEO and AI

Internal linking guides Google's crawl: links invisible on the first pass slow down page discovery. AI systems that follow links in the raw HTML will not navigate your site.

When it is NOT a problem

  • The main links (menu, footer, contextual links) are already in the raw HTML and only secondary links (filters, dynamic pagination) are injected via JS.
  • Your XML sitemap already exposes every important URL: Google discovers them through that channel even without a link in the raw HTML.
  • This is an internal app interface, not meant for crawling or indexing.
Before
<!-- Raw HTML: empty navigation -->
<nav id="menu"></nav>
<!-- links added later by JS -->
After
<!-- Raw HTML: real links present -->
<nav id="menu">
  <a href="/trail-shoes">Trail</a>
  <a href="/road-shoes">Road</a>
</nav>

Google and AI systems follow the a href tags in the raw HTML; an onclick or a JS router does not replace a real link.

How to fix it

  1. View the raw page source (Ctrl+U) and check that your menu, footer and navigation links appear there as a href tags.
  2. Render navigation server-side (SSR/SSG) instead of building it on client-side mount.
  3. Use real a tags with an href attribute, not div elements with an onclick handler.
  4. Re-crawl to confirm the links are present in the raw HTML.

Frequently asked questions

Does Google follow links added by JavaScript?

It may follow them on its second rendering pass, with a delay. Links present in the raw HTML are discovered immediately, on the first crawl.

Does an XML sitemap replace internal linking?

No. A sitemap helps discovery, but internal links also pass context and hierarchy between your pages, which a sitemap does not do.
