The mechanism
Separate sources, one table
The crawl, your server logs, rank readings, Search Console and answers from AI engines arrive at different moments, down different paths. They land in the same data model, on the same normalised URL key. That is what makes cross-referencing possible, and it is what a pile of separate tools will never catch up on.
One write path
Every module writes its rows into the same schema, on the same normalised URL key, port included.
Cross-referencing costs nothing
A crawled page, its log entry, its ranking and its AI citation read together because they already share that key.
What comes out of it
Recommendations and signals come from the cross-reference, not from one isolated module seeing a third of the problem.
