Well, after spending 45 minutes trying to figure out github, I've realized I'm not as much of a nerd as I thought.
So, in the mean time, here's a nice ZIPped archive of the code for the Levenshtein link redirector I've written in PHP. I've named it the Levinator - Dr. Doofenshmirtz would be proud.
I've talked about it before, but here's the rundown.
This tool compares a list of good URLs and 404 URLs.
Then, using Levenshtein distance calculation, it figures out the closest-matching good URL for each broken one.
Finally, it generates a list of 301 redirects, .htaccess-style, so you can set up redirection.
You'll need:PHPBasic knowledge of coding (very basic)A list of good URLs on your siteAnd a list of 404 errors - easy to get from Google Webmaster Tools
