Selection Rate

The rate at which an AI system chooses a given source from the available grounding candidates when composing an answer; the AI-search equivalent of click-through rate.

Selection Rate is the rate at which an AI system chooses a given source from the grounding candidates available to it when it composes an answer. It is the AI-search equivalent of click-through rate: where CTR captured a person picking a link from a list, Selection Rate captures a model picking a source to ground its reply on.

Raising it is the aim of Selection Rate Optimization. Related: AI Visibility.

Primary Bias

Primary bias is what an AI model already believes about your brand before it searches: an ungrounded confidence baked into training that becomes the biggest factor in whether your content is selected in AI answers.

Grounding Snippets

Grounding snippets are the short, extractive sentences AI systems pull from your page to build their answers: the atomic unit of AI-search visibility, where most of your page never makes the cut.

Selection Rate Optimization

Selection Rate Optimization is the AI-search counterpart to click-through-rate optimization: improving how often AI systems choose your content as the source they ground and cite their answers on.
