Successful SEO requires a thorough understanding of the business itself. The length of your content isn't necessarily an indicator of thinness, Google can also judge the value of content with the "time to long click" metric, which measures how long a user stays on a page after finding it on a SERP before going back to the search engine and clicking on another result or making another search. Website Optimization is important for making users feel comfortable while using your website, as well as collecting information from those users to further your advertising goals. The old saying that "life is a journey, not a destination" can also be applied to SEO. The majority of learning can be done online, but some should be done in real life.
