Sources

Why do certain sources appear in AI answers?

A source in an AI answer is a link that the AI search engine visibly supplied for fixed search prompts. Such a link is a valuable evidence point: it shows which address was supplied. It does not prove why the source was chosen or whether every sentence of the answer comes from it.

Answer of an AI search engine to prompt 7 of 20 · search intent comparison · fictional and shortenedFictional teaching example, not a measurement

“Which kitchen makers plan a made-to-measure kitchen island?”

For a kitchen with an island, trade media mention above all Talwerk Küchen¹ and Example Provider B². Regional studios can be found in trade directories³. For made-to-measure work, planning depth and delivery time decide the right choice.

Mention: Yes Talwerk Küchen
Supplied sources: 3, of which 1 own
Source of the mention: own pagetalwerk.example/planung

Footnotes 2 and 3 are supplied sources unrelated to the mention.

All names, prompts, answers and addresses are fictional; domains end in .example. What is visible is which address the AI search engine supplied, not why it was chosen.

In short

A link is evidence, not a justification.

A supplied source is an observed URL or domain that was visible at a specific AI answer. It is a verifiable hint, but not complete proof of how the answer came about, how it was weighted or whether it is correct.

Step 1 · EvidenceFictional example: Talwerk Küchen

What gets documented is what was actually supplied.

A source starts with the exact visible address. Domain, page title, order and measurement context are recorded as far as the measurement path supplies them. URL, domain and page type stay separate, because each of them answers a different question.

A URL is never invented. Redirect addresses and shortened links are labelled as such. If a target address is missing, it is not guessed from the title or domain name, and a presumed canonical page does not quietly take its place.

Step 2 · TypesFictional example: Talwerk Küchen

Own page and third-party source tell different stories.

An AI answer can link the own page, a trade medium, a directory or a forum. What matters for the assessment is whether the source belongs to the own domain and what kind of page it is. A third-party source can mention, compare or misclassify the brand. An own page can appear as evidence without the brand appearing in the answer text. Mention, observed position and source remain three separate values, as the fundamentals article on AI visibility shows.

Supplied sources and source of the mention are two counts. Only the source attached to the mention of Talwerk Küchen is counted here: 12 of 20 observations mention the brand, and for each of these 12 the source type is recorded.

3 own, 9 third-party sources of the mention, each of 12.

Step 3 · CheckFictional example: Talwerk Küchen

The link is the start of the check, not its end.

Four questions belong to every supplied source: Is the address reachable and does it belong to the documented domain? Do page title and topic match the statement in the answer? Is the information current, specific and technically verifiable? And is it own, independent or aggregated information? Why a page is not cited in the first place is explained in the article on the citation path.

In the example, the answer claims that trade media mention Talwerk Küchen. The link at the mention, however, leads to the own page. It proves the supplied address, not the claim.

A technically successful retrieval proves no factual truth. Reachability, domain and page title are checked by machine. Whether topic, currency and role are right is checked by a person for important findings.

Step 4 · PracticeFictional example: Talwerk Küchen

Three links, three different roles.

The own planning page describes technical data but still uses an outdated product name. The article in the trade medium compares several solution types and mentions the brand in the right market. The directory lists the right domain but files the company under a category that is too broad.

The sensible measure is not “more keywords”. First, check which page can actually correct an unclear or outdated statement and whose hands it is in. Whether the supplied source changes afterwards is shown only by the next observation, not by a forecast. In which source types a brand should deliberately appear is shown in the article on source work.

2 trade mediumkuechenmagazin.example/kochinsel Finding: brand mentioned in the right market third-party hands · editorial team, observe

3 directoryhandwerk-verzeichnis.example Finding: category too broad in the entry third-party hands · request a correction

Check first, then change

1 of 3 supplied sources is in your own hands.

Next step: update the product name on talwerk.example/planung, then measure again.

Honest limitFictional example: Talwerk Küchen

What source observation does not prove.

A link does not prove that it was the only basis of the answer. Its order is no permanent quality ranking, and a change of sources between two measurements proves no specific cause.

Direct API and the visible consumer interface can supply different links for the same search prompt. Sources are therefore kept per measurement path as their own time series with time and exact address, not as a justification for an overall score.

Sources belong to visibility but do not replace it.

The fundamentals article shows how mention, observed position and sources are evaluated together but separately.
