SEO (search engine optimization) can take a long time for several reasons. One of the main reasons is that it involves making changes to a website in order to improve its ranking in search engine results. These changes can include things like optimizing the website’s content and structure, improving the website’s technical performance, and building high-quality backlinks from other websites. Making these changes can take time, especially if a website is large and complex. Additionally, it can take time for the changes to take effect and for the website to start ranking higher in search engine results.
