I'm trying to analyse all my competitors using Moz, lighthouse and other backlink SEO tools to understand the pattern of what validates number 1 spot. This includes traffic, speed, alt tags, DA, PA, headers and text but can't see why one site sits at the top for a set keyword search and has done for some time. I'm still on page four after a month of ironing out issues but can't see how I'm failing, my sitemap is kicking out an error and I'm with a website platform and not sure how to fix it. It's one of the few things left on my list of things to try. Any thoughts.
