Links have been a relatively long-time ranking factor for SEO and expect no different in 2015. We did see that quality backlinks are important and the total quantity of links are still an important SEO factor. However, links with exact-match keywords are becoming less of a ranking factor.

When another website links to your website, Google views this as a trust ranking factor. You can view it as if it is a vote for your website. This is why you should only link to authority websites, websites that you trust. Backlinks are always going to be important, that is likely to change anytime soon.
