When figuring out if ranking drops result from a change on Google’s side or your own, it’s helpful to know if anything changed on the page that lost rankings.
Sometimes, these changes aren’t well documented, especially if multiple stakeholders can edit pages. Or there may not be a changelog system that enables you to find what was changed. It may even be that the changelog system doesn’t show the complete picture and doesn’t include broader changes that impact internal linking or alterations within the HTML head or anything outside the main content area. Although I think it’s best to work towards creating an internal system that accounts for all of this, it’s not feasible for every organization or SEO professional. What do you do?
