Google has added a lot of good information to this page:
http://www.google.com/webmasters/
You should read it several times and use the free tools Google provides.

Google has illegally broken into my Blogs over 100 times. Google has edited and illegally deleted some of my content. Additionally, X, Meta, and Google are still censoring many people, including me. Elon Musk never fixed any of the evil censorship that Jack Dorsey and his team built into the X software. We do not have online freedom of speech.
