Questions covered
Answers
How does the plugin detect changed pages?
The plugin hashes the final generated HTML output for each page and compares it against a stored hash from the previous build.
Why hash the final HTML instead of source files?
Hashing final HTML ensures that only real, user-visible changes trigger submissions, regardless of where those changes originate.
What is the cache file used for?
The cache stores URL-to-hash mappings from the previous build so the plugin can detect which pages have changed.
Should the cache file be committed in Git?
Yes for CI/CD. CI environments are ephemeral, so committing the cache file allows correct change detection across deployments.
What is IndexNow?
IndexNow is an open protocol that allows websites to notify participating search engines when URLs are created, updated, or removed.
Which search engines support IndexNow?
IndexNow is supported by Microsoft Bing and other engines that have adopted the protocol. Support may change over time.
Does Google use IndexNow?
No. Google does not currently use IndexNow. Submissions have no effect on Google Search.
Does IndexNow improve rankings?

Does Astro IndexNow affect site performance?

Is Astro IndexNow safe to use in CI/CD pipelines?
Yes. The plugin is deterministic, side-effect free, and designed for automated build environments.
What are the limitations of IndexNow?

What are common misconceptions about IndexNow?
Common misconceptions include believing IndexNow boosts rankings, replaces sitemaps, or forces indexing. None of these are true.
