On-page checks that affect how search engines read your site.
These checks cover the fundamental on-page factors, title tags, meta descriptions, headings, structured data, and more. Getting these right is the foundation of any successful SEO strategy.
Speed checks that affect how fast your pages load.
Page speed is a confirmed Google ranking factor. These checks measure load time, Core Web Vitals (LCP, CLS), compression, caching, and rendering to identify exactly what is slowing your site down.
Security checks that affect how safe and trusted your site is.
Google favours secure, trustworthy websites. These checks verify your SSL certificate, HSTS headers, mixed content issues, SPF records, and HTTP/2 support.
Advanced tests that catch technical issues most sites overlook.
Technical checks that are easy to miss but can still hurt crawlability and user experience, including deprecated HTML, inline CSS, mobile responsiveness, and correct doctype declarations.
