SEO technologies have changed quite a lot in the last few years. What should SEO specialist take into consideration to efficiently promote websites?
Search engines are constantly tightening rules. For example, earlier it was recommended not to buy links. Today it is penalized (Google's Penguin Algorithm and Yandex Algorithm Minusinsk). If earlier there was a tendency to build up a link profile, now it is usually cleaned up. Today a large amount of links is used only for grey market websites, and it is unacceptable to use them for white market websites.
New algorithms are also tracked in order to ensure that there are no advertisements and popup windows in the first result screen, and to make sure that website offers content relevant to the query, etc. In the end of the last year Yandex began to penalize websites for clickjacking – allocation of hidden elements in order to fraudulently collect user’s private data.
Transformation of ranking factors
New services also appear. For example, for promotion of commercial websites one can use Yandex.Spravochnik. Addresses of company offices can be stated there to make them available in contacts. It will influence snippets; people will be able to leave feedbacks there, which will influence ranking in general.
