The relevance is defined by two factors: internal and external. Internal depend directly on the website. External are thematic links which will enter on the necessary page. However ideal indicators do not exist. Depending on competition of request and subject, they can significantly differ. The relevance is defined, analyzing these factors.
Content

It is the best of all to use direct occurrences of search query or its morphological forms. It will allow search systems easier to define relevance of content.
The following indicator – convenience of reading. Surprisingly, but search engines pay attention and to it. The more will be different graphic elements, the better. Diagrams, the marked lists, pictures, video, subheadings, selection bold, italics, underlining and quotes. Surely pay attention to all these means as they play an important role.
Other factors
In addition to the factors connected with content there is also some other. The age of the website and its different indicators are also important. The resource will be more senior, the it is easier to advance it in a top. Search engines already trust content which is located on its page and consider them more relevant.

Also relevance indicators of tITs and PR indirectly influence. Than more websites refer to a resource, especially reliable it is considered in terms of search engines. From here also the external factor of relevance – the reference mass of the page follows. Than it is more, that more usefully information on it contains.
In addition to external references links internal are considered. If the search robot sees that this information is relevant also within other articles, then increases its importance. In particular, by means of powerful internal relinking Wikipedia moves ahead.
