The agent works exclusively with measurable sources: Google Search Console for clicks, impressions and positions, the PageSpeed API for load performance and field data from real visits, plus link and competitor data for context. Search Console numbers only become final after a few days, so the agent builds its monthly report on final data rather than fleeting daily numbers.
Those sources also set the limits. When the agent sees a page with many impressions but few clicks, that is a strong signal for a better title or answer structure. Why a searcher does not click through, no data source knows for certain; that takes the judgment of someone who knows your customers. Data steers, people weigh.
