The source gap analysis method described by Peec AI
Peec AI suggests starting from a well-tagged prompt tracking project, filtering cited sources for your own domain, then comparing the most and least cited URLs using the average citation rate. The gaps show what to create or rewrite.
Source gap vs brand mention gap: two complementary analyses
Source gap analysis is about cited URLs. Brand mention gap analysis is about prompts where competitors are named and you are not. Peec AI treats them as two parts of the same approach.
What to do with cited sources that are not yours
If AI cites comparisons, forums or third-party media, two options: create a page that answers the same intent better, or get present on those sources (digital PR, reviews, contributions). Also look at the source type cited for each prompt.
