When you get right down to it, search engine optimization and user experience design actually have the same goal: happy users who can quickly and easily find exactly the information they’re looking for.
SEO and UX design actually have the same goal: happy users!
Users who find the information they are looking for by searching on a website that is clear, appealing, and invites them to spend more time on it, ultimately create positive user signals.
The experience of your users does not only refer to the perception of your «static» content, but also strongly to the interaction of the users with your website. The more interaction you enable, the more time users will spend on your site and this in turn has a positive impact on your ranking.
