About Yandex

Remember there was such a thing when vebalta showed a banner on which there was a search query that you entered earlier in Yandex?
I don’t know, maybe I missed something, but now Yandex.Direct shows me contextual advertising on the subject of my request. Ie, I looked for something on I and left the search, went, for example, on Habr and I see an advertisement of what I was looking for!
