I relocated my blog to the main directory of my site. I didn't really have any plans to design another site around the blog, so I decided to just go ahead and move it.
I didn't think about google and the people who are directed here through links. Unfortunately, I assumed that google would eventually drop the dead links from the database, and pick up the new directory. I don't know why I didn't think to alter my .htaccess file to redirect people automatically. After all, all I did was change from http://www.jojometal.com/blog to http://www.jojometal.com. The files are all the same, so it wouldn't have been a big deal to add a redirect. I just wasn't thinking, I guess.
So, if you're in a similar situation and you want to change your site structure and help ease the transition for users and search engine spiders, here's what I did to my .htaccess file to redirect any user looking for an old file to the new one (This assumes, of course, you have a text document called .htaccess in your root directory).
I added:
RedirectPermanent /blog http://www.jojometal.com
This line just means that whenever someone requests http://www.jojometal.com/blog/anyfile.htm they will be redirected to http://www.jojometal.com/anyfile.htm. The "redirect permanent" instead of redirect lets clients know that it's a permanent move. This method will redirect for any type of file in that directory, not just .htm files.
I'm still trying to find out why google's spider won't start crawling my content at jojometal.com. I know it's in the index, but it hasn't updated it in quite a while. It updated the blog directory really frequently. Hmmm...
