Selection Rate measures the gap between being found and being chosen. It answers: when an AI engine retrieves your domain as a candidate source, how often does it end up in the final response?

How it’s calculated

Of the responses where an engine retrieved your domain as a candidate source, Selection Rate is the share that ended up actually citing it:
  • Sources — the responses where your domain appeared in the engine’s retrieval pool (the pages it considered)
  • Citations — of those, the responses where your domain was actually cited in the answer
Because it’s measured per response rather than by counting raw mentions, Selection Rate always stays between 0 and 100%.

What it tells you

A low Selection Rate means AI engines are finding your content but choosing competitor content instead. The most common cause is a low Alignment Score — your content is present but not structured well enough for the engine to cite confidently.

HighYour content is retrieved and selected — a strong signal of content quality and alignment
LowYour content is retrieved but skipped — alignment or content depth is likely the issue

How it differs from Citation Share

Citation Share measures your citation share across all citations. Selection Rate is scoped to your own retrieval appearances — it isolates the question of why you’re not being cited when you do show up.
Selection Rate is a secondary metric. Use it alongside Alignment Score to diagnose why citations are lower than expected.
