20 Search Engine Optimization Mistakes

A Web site called Search Engine Land calls them "fatal" mistakes, and that is pretty true. You really do want to avoid all 20 of the search-engine optimization slipups on this excellent list.

A couple of examples:

5. Don't spread your content over several domains. There are times when sub-domains or an additional domain might make sense, but those occasions should be dominated by user and content considerations, not an attempt to get multiple domains/sites listed in the SERPs [Search engine results pages]. Know the pros and cons of using sub-domains and additional domains.

7. Don't make your Web site uncrawlable. This can result from an incorrect robots.txt file, having session IDs or too many variables in your URLs, using a convoluted navigation menu that spiders can't (or won't) follow, or developing an all-Flash, all-graphic, or all-AJAX site.
