RankBrain has been a significant ranking factor since the past few years, and will continue to be so in 2018 too. And, this element is clearly linked to various user experience signals like on-page time and CTR. To make a place for yourself at the top of SERPs, you need to satisfy Google’s RankBrain by writing compelling on-page content, having a fast loading website, include relevant images and videos, optimize title tags and metadata, etc. In short, you need to work towards providing your users with a flawless online experience on your site.
