- Inadvertently tell the search engine spiders not to index your files, via robots.txt or metas
- Completely change your URLs and don't 301 redirect the old ones to the new ones.
- Employ techniques that irk the search engines (let's use hidden urls to porn sites as an example) and then make sure to badmouth an SEO. Watch how fast that SEO will scour your site for problems and then report it to the search engines
- Give Matt Cutts grief on his blog, being sure to include your URL. Watch him not only investigate your site and throw it in the trash heap, but give you the ultimate embarrasing smackdown as he bares all your mistakes to the world on a future blog post.
- Be complacent, do nothing, let the site lie fallow, and assume you'll always have your great rankings. (Ok, this one might not be fast, but it will be surprising!)
This post is participating in Problogger's Top 5 Group Writing Project. The best thing about this project is the ability to discover great new blog sources. Next week, I'll link to some of the Top 5 posts that I enjoyed the most. Hopefully, I can read at least most of the entries over the next few days.
