Google’s algorithm cleverly uses links to rank websites. A variety of variables are considered; however, some of the factors that are considered by the Algorithm are whether it is from a trusted and relevant source. The ideal link sends relevant, targeted traffic from one site to another.
Links are one of the top three ranking factors. To create a good SEO strategy, it is important to consider that it is not the quantity of the links that matter, but rather the quality. The ideal link-building strategy should aim to include as many quality links as possible.
