Not an idle question arose in connection with the alleged desire of Yandex give the user the sites with the most complete information on request and, where possible, and give her into the results. And microformats are just working on the user that is allow at least to give an informative snippet in the results. The idea is that this is a very positive ranking factor.
It's also possible that the presence of microformats allows to consider the layout as a whole better.
Did any of you experience of implementing microformats and then rise in the results?
Share it, please.
