The basics still remain the basics, and there is no way of going around it. Be sure to have a functional website that is up to date, clutter-free and mobile adaptive. Remove any broken links or unnecessary content that opens up unrelated topics. And for each page, create proper titles and descriptions that describe what the page is about.
No matter what your SEO strategy is, the basics still remain basics. Fixing the above may be all the difference you’ve been looking for.
