To truly understand whether your SEO campaign is working, you need to learn which measurements deserve your attention. If you structure your site to rank well on search engines, you can compete with businesses targeting the same customers. However, the subsequent updates, especially the more recent manual actions, have finally brought us more clarity on the subject: it's not about the quality of the content but the value that content adds to the users. The main heading of your page tells visitors, including search engines, what the page is about. Heading tags let us mark up what is a heading or sub-heading on the page, and we can use the h1 tag to show the primary header. Most CMSs do this automatically. It does not have to be done all at once, and it usually never is.
