Definition
An indexation mismatch is when a sitemap lists a URL that canonical, robots, or status code does not present as the indexable page. The sitemap and the signals that govern indexability disagree about that URL.
Short answer
A sitemap lists a URL, but the canonical, robots rules, or status code does not present that URL as the indexable page. That disagreement is an indexation mismatch.
What to check
- Sitemap lists the URL
- Canonical may disagree
- Robots rules may disagree
- Status code may disagree
What this does not claim
Finding an indexation mismatch does not guarantee that aligning the signals will change rankings. Mika does not guarantee search rankings or AI answer citations when sitemap, canonical, robots, and status signals are brought into line.
A practical example
A sitemap can include a URL while the canonical points to another URL, robots marks the URL noindex, or the status code does not present it as a successful indexable page. Any of those conflicts is an indexation mismatch.
