Yandex has announced a change to its browser that it claims makes it the first of its kind. The company's Zen technology, which allows for personalised content recommendation, has been implemented into its browser and will available in 24 countries and 15 languages. Zen will use Yandex's huge global web index to select content as recommendations for each user of the browser. From there users will then be able to like and dislike pages to educate Zen on what sort of content they prefer. Whilst this service is already available on mobile devices, this is the first time it has been available on a desktop browser. This came shortly before Yandex also announced that it had changed the calculation for its Thematic Index of Citation, or TIC. These new calculations mean that there have been changes to inbound link-based signals, whilst other 'outdated' signals have been excluded, but no other details were given.
