I suggest the 2014 Position Variables Study released by the SearchMetrics men, in the event you would like a refresher. You may also read about how exactly they performed the studied, the best way to interpret the amounts etc, although the image is summarized by the infographic.
Website practical quality is gaining significance. To put it differently, in case your web site has HTML errors, is not fast or not optimized for cellular devices, your rankings will suffer.
Backlinks stay a significant variable. Nevertheless, Google is looking to place much more emphasis on the caliber and relevancy of the links, and it is also attempting to divide natural vs. man-made backlinks.
Websites that are important appear to appreciate additional exposure in the search ranks, so concentrate on building a brand all around your website.
