Users of Yandex’s search engine will find their long-term and short-term interests are now being taken into consideration. The company believes it can build results pages based on the ‘full picture’ of a consumer’s online behaviour.
With Dublin, the name afforded to the new algorithm, a football fan searching for “Manchester” might receive results related to the city rather than football club. Personalised search will only do this if the user has pre-defined search intent for English cities.
Before the update came into play, Yandex combined both long-term interests such as football and more temporary queries like a wallpaper for some planned redecoration in an update that occurred once a day.
Yandex now analyses search sessions in real time, so it can respond to consumers’ fleeting urges soon after they arise. More than half of Yandex’s users are motivated by such short-erm interests, according to the company.
The real-time indexing has meant that search queries on Yandex influence search results within seconds. From the start of a session, the search engine is able to fathom whether a consumer is looking for a TV series or a film when they type “George R. R. Martin” for instance.
Reykjavik was the first iteration of Yandex’s personalised search that delivered results based on language preferences. It was followed by Kaliningrad, which adapted to the ongoing interests of the site’s users.
With Dublin, all users can benefit from the latest personalisation updates. Even a newcomer will notice results being tailored to their interests. Yandex has stated its data centre processes 10 terabytes of data a day when reacting to consumers’ searches.
