Earlier today I was running a small SEO audit on a small WordPress site and I noticed that all Feedburner links were 302ing. This means that the search engines only view them as temporarily moved. So I looked under the hood and saw that the FeedBurner FeedSmith plugin was installed. Apparently this plugin uses 302s to redirect the feed. So I went in and edited the plugin to handle 301s. You can download my edited version below.
Hope you enjoy!
