Google has numerous ways to determine the quality of content of a post. When Google goes through content of a post or page for ranking, certain factors are taken into consideration such as links, keywords, tags and back links. More the number of back links more are the chances for the post to come up at the top. Bringing out the best quality content to the user is at the utmost priority in Google’s list.
Links are one of the finest ways to estimate the quality of a post. A hyperlink is generally a web page linked to the current post which indicates something valuable related to the post updated. Anyone can link their webpage to a post, which is why Google considers it as the prime reference for quality content.
A question has been raised by a Google user stating if there aren’t a lot of links, how Google determine the quality of the content. For this, Google uses the same process which was followed long before links came into existence; how search engine worked before prior to links.
Therefore, in such situation Google verify with the text in the post. First time it notices a keyword surface out, Google counts on it and if the keyword keeps repeating over and over again, Google understands the topic of the page but at the same time too many a times repetition of a word diminishes the value of the page. Also, the domain on which the post is updated matters.
Typically, how it’s evaluated is when a user types in a really rare phrase or word and if there are no other pages or very few pages containing that particular phrase, then that page can be returned in the higher ranking of the search results even though the page might not have many links.
