The first criteria that are possibly going to be added are the amount of Click data. It has been noted that Google news does not use links as a ranking factor rather it uses clicks or the amount of clicks as a ranking factor.
Second Criteria is web referencing, a web reference is not a link but rather a mention of the target website in an external website. This means that the mere mention of your website from another website which you do not own is already considered as a ranking factor, not just by links anymore.
A third criterion is the presence of your website in social media networks. Social media is now considered to be the latest craze among different walks of life and the popularity of your website in a social media community will contribute greatly to your ranking.
Finally, page loading time is also going to become a factor nowadays that is why website design and web development will play an important role in the field of SEO. The rationale behind using page loading time as a ranking factor is the fact that fast page loading time improves user experience.
With these new criterias added would it help revolutionise the search engine algorithm?, we might also see another shift in terms of the SEO approaches being done by different SEO companies and SEO consultants
