Paid links will be a negative ranking factor for Yandex
Yandex is to update its search engine ranking algorithm to make paid links a negative ranking factor.
Last year, Yandex announced that paid links were to be removed as a ranking factor for shopping queries in the Moscow region. The rationale was that paid links were a dishonest practice being abused by black-hat SEOs intent on artificially pushing up a website’s ranking in the search engine results pages.
Yandex hoped that by removing paid links as a ranking factor it would discourage black-hat SEOs from using the tactic, however, it found that there was only a 16% decrease in paid links in the last year.
Therefore, it has reintroduced links as a ranking factor, with paid links considered a negative ranking factor that would actively demote a website’s ranking, and natural, organic links a positive ranking factor. ​
Yandex says that its machine-learning based algorithm can tell the difference between these paid and organic links.
Alexander Sadovsky, head of Yandex search, has commented on the algorithm change, saying that the search engine wants to improve the quality of links in the long-term by penalising websites with paid links.
The new algorithm will be rolled out from the beginning of May and will cover all websites across the whole of Russia.


В кратком изложении:
с мая платные ссылки будут не просто игнорироваться, а считаться негативным фактором при ранжировании.
