I know that SEO is about search keywords, metatags, unique content, among other text parameters. But does the way the page look affect the SEO in any way? For example, if my keyword is on the left or the right of the page, does it change my ranking? And how about an AJAX pagination with numbers and arrows apparent versus a Lazyload pagination where we need to scroll down to see more pictures? As for responsive design, Google will let you know if your page cannot go on mobile, because you will lose a major audience this way. If a website is not responsive, it will go down in the search ranking.
