Is your site ready for Google's mobile-first index? This tool compares your mobile and desktop pages and reports on discrepencies between SEO signals (canonical, meta robots, hreflang tags, etc.), content (page title, links, alt="text", etc.) and structured data markups. It also checks if your page is mobile-friendly via Google's API.
