A page that can't be crawled or indexed can't rank, no matter how good the content is. NitroShock's Site Audit doesn't have a separate "indexability" section - instead, several of its checks together cover the reasons pages drop out of search. This guide maps them and shows how to work through indexability problems.
The Checks That Cover Indexability
- Page Accessible / 4xx / 5xx - a page returning an error can't be indexed. 4xx means the URL is wrong or gone; 5xx means your server failed while responding.
- Redirect Status - redirects pass indexing signals to their target. Chains and loops dilute or break that; audit findings show where redirects lead.
- Canonical Tag - a canonical pointing elsewhere tells Google to index the other URL instead. Wrong canonicals silently deindex pages; missing ones let parameter variants compete.
- HTTPS / Mixed Content - protocol problems and insecure resources undermine trust signals and can split indexing between http and https variants.
- Orphan Pages - pages in your sitemap with no internal links pointing at them. Google can find them via the sitemap, but linkless pages crawl less often and rank worse. The audit flags each one.
- Sitemap cross-check - URLs in your sitemap that the crawler couldn't reach are audited anyway, which surfaces sitemap entries that error out or redirect.
Noindex Is Respected, Not Reported
Pages marked noindex are deliberately excluded from search, so the audit strips SEO checks for them instead of flagging them as failures. That means a clean audit doesn't guarantee a page is indexable - if a page you expect to rank is missing from results, check for a stray noindex tag or header first. It's the single most common cause of "my page disappeared."
A Triage Workflow
- Fix errors before optimizing. Work 4xx/5xx and broken redirects first - they're binary blockers.
- Audit your canonicals. For each canonical finding, ask: does this point where I actually want indexing consolidated?
- Link your orphans. Every orphan page either deserves internal links or doesn't deserve to be in the sitemap. Decide per page.
- Re-check the fixed pages. A Single Page Audit (6 credits) confirms a fix without re-crawling the site.
Verifying with Google
The audit tells you what would keep Google out; Google Search Console tells you what Google actually indexed. Use GSC's URL Inspection for a page-by-page verdict. If you connect Search Console on your project's Intelligence page, NitroShock also monitors your real clicks and impressions and flags visibility drops - which is often how an accidental deindexing gets noticed in time.
FAQ
Why doesn't the audit list my noindexed pages as issues?
Because noindex is treated as intentional. The audit avoids drowning you in "issues" for pages you excluded on purpose.
The audit is clean but my page isn't in Google - why?
Check for noindex, check the canonical target, and inspect the URL in Search Console. Indexing also simply takes time for new pages, especially without internal links.
Does NitroShock check robots.txt rules?
The crawler behaves like a search crawler when fetching pages, but there's no dedicated robots.txt rule analyzer - review directives manually or with Search Console's tools.
