It's important to ensure your website is accessible to all users (including SEs) on all devices. We take a dual approach to accomplishing this, which includes website audits and index analysis. For website audits we take a look at the information architecture, semantic mark-up, and 404 pages. While for index analysis, we look at XML site maps, robots.txt files, and 301 redirects. This two-pronged approach ensures a healthy and accessible website.
