Which citation sources most influence visibility in AI search?
Metric
The main citation sources are the domains models draw on most often when answering about a brand or a category; Bikma classifies them by type and Domain Authority.
How it works in Bikma
This metric belongs to the External Sources module, which labels every domain by category (news, retailer, reviews, forum, official site) and estimates its standing with Domain Authority. That separates the sources that really carry weight from the marginal ones, and shows which ones feed the brand and which feed its competitors.
The earned-media lever
Because generative engines favour third-party sources, improving visibility often means earning coverage on authoritative external domains, not only updating your own site. The map of sources shows where to concentrate digital PR and where to hold a presence on the platforms models treat as reliable.
Why it matters
Sources are the raw material of AI answers: acting on them is the most direct way to change what the models say about the brand.
