Google works at a dynamic scale. It carries out multiple actions simultaneously and with a magnificent effect. A question which Google face frequently is whether it has another adaptation of the search engine in which back link relevance is totally excluded.
Back links are links that gets directed towards your website. They are also known as inbound link. The more the link is relevant; the better will be the ranking of the web page. Relevance means when there are more inbound links, which are related to your content, linked to your web page.
For example, if you have a website of how to make apple pie and maple syrup and you have received back links about maple syrup pie and on apple crush, then your web site will be more relevant.
Getting back to the question, Google albeit has tried to run experiments without back links internally, and the result being worse, do not have a version like that. Bank links, although has lot of spam and noise, in most cases it has effected positively in terms of quality in search results.
Therefore, Google has rejected the idea of turning off the back link relevance. At the moment back link relevance really helps in acquiring the most significant search results.
