A page can only rank if Google is allowed to index it — and if the right URL is marked as the master copy. Indexability bugs are the most damaging in SEO because they make good content invisible. Here's what we check and why.
You can have the best content and the strongest links in your niche, but if a page carries a stray noindex or canonicalises to the wrong URL, it will never rank. This is the highest-leverage category in any audit.
Indexability is binary at the gate: a page is either eligible to appear in search or it isn't. The cruel part is that these failures are silent — the page loads fine for you, but a single line in a template or a misconfigured canonical removes it from search entirely. The explainers below cover the two areas where this goes wrong most: canonical tags and the noindex directive.
The two checks that deindex more pages than anything else.
How rel=canonical works, the canonical mistakes that quietly deindex pages (pointing to a redirect, a 404, or every page to page 1), and how to keep canonical, hreflang and internal links aligned.
When noindex is the right tool, when it silently kills rankings, and how a stray noindex on a shared template can deindex an entire section without anyone noticing.
Grounded in the real checks the crawler runs on every page.
noindex pages · noindex-follow and noindex-nofollow pages · pages that became non-indexable since the last crawl · canonical URL changed · canonical points to a redirect, a 4XX, or a 5XX · canonical points off-domain · canonical from HTTP to HTTPS (or HTTPS to HTTP) · canonical URL with no incoming internal links · non-canonical URL receiving organic traffic · the same URL linked with and without a trailing slash.
