This is a great list of SEO tips. One tip you can add to your broken links section is that there is a free tool called Xenu Link Sleuth. It will automatically crawl your website (or a competitor’s site) and find all the broken backlinks (and lots of other things). It’s very helpful if you have a large site or need to find broken links you aren’t aware of. (like images and .pdf files)
