не эксперт в SE, но думаю, что влияет. Во-первых, имеется небольшой личный опыт, во-вторых, в патенте Гугла есть такой пункт:
[0090] Additionally, or alternatively, search engine 125 may monitor time-varying characteristics relating to "advertising traffic" for a particular document. For example, search engine 125 may monitor one or a combination of the following factors: (1) the extent to and rate at which advertisements are presented or updated by a given document over time; (2) the quality of the advertisers (e.g., a document whose advertisements refer/link to documents known to search engine 125 over time to have relatively high traffic and trust, such as amazon.com, may be given relatively more weight than those documents whose advertisements refer to low traffic/untrustworthy documents, such as a pornographic site); and (3) the extent to which the advertisements generate user traffic to the documents to which they relate (e.g., their click-through rate). Search engine 125 may use these time-varying characteristics relating to advertising traffic to score the document.
когда патент только появился, помню, кто-то пошутил, что теперь все дорвеи будут забиты рекламой амазона...  но мне кажется, что вместо рекламы амазона Гугл вполне может использовать Adsense... |
