All search engines, including Yandex, tell you to create great content. They also tell you that the content should be unique. But what if your content gets re-posted somewhere, and what if that copy-paster ranks higher than you? This situation, I am sure, is familiar to most of us.
Search engines have been pretty good at determining the primary source of content, but sometimes they do get it wrong, and Yandex does more often than Google.
In 2011 Google came up with a way for authors to protect their rights in the SERPs with rel=”author” tag. It has proven to be a very good way to show Google the true ownership of the content as well as build up authority of you as a writer. Unfortunately, Yandex does not support rel=”author” tag. But there is an alternative.
