I'm trying to brainstorm keywords for the website I'm going to start up. I know a lot of sites that are like the one I want to start and I'm curious if there is a way to see what keywords they use. Some sites don't have it in the meta tags or have hidden the source code altogether. Also if I use different keywords as anchor text to different pages in my website would that hurt the SEO? I'm guessing it's better just to link directly to the main index page? Most of these sites I'm research are PR 0-3 which is surprising because they're all on page 1 of google for the keywords I typed in. What does PR have to do with the relevance of a keyword? Thanks for any direction you guys can give me on researching and destroying my competition.
