Frequently asked questions
Can I crawl only an input list?
Yes. Use list mode for a controlled URL sample.
Does an indexable crawl status mean Google indexed the page?
Check indexing separately. The crawler reports what it retrieved under its settings.
When should I compare HTML with rendered output?
Use a representative sample when key navigation, copy or directives depend on JavaScript.
What should I check after finding a redirect chain?
Verify the final target and status, then test whether the first URL can point there directly.
Is generating a sitemap the same as submitting it?
Generation creates the file. Submission and indexing are separate steps.

What should I check next?
How do I QA 300 redirects before a US ecommerce replatform?

Which sample should I recheck after launch?
Retest key entry pages, redirect chains and a few URLs from each affected template.
Which technical SEO signals can I inspect with SEO Spider?
Use the crawl to examine status, redirects, metadata and canonicals for the scope you configured.
How do I find indexability issues in a supplied sitemap?
Review non-success statuses, noindex directives and canonicals for the URLs you intend to include.
Would I choose SEO Spider or a dashboard audit for a one-time URL move?
Use SEO Spider when an explicit list and fine-grained crawl settings are central to the check.
What should I confirm before licensing a migration crawl?
Check URL count, rendering and the reports you need against the current license terms.
Who needs to review the output of a JavaScript crawl?
Bring in the developer who owns the affected template so they can verify where links and directives are produced.
