How to redirect an RSS feed to Feedburner in WordPress
In every blog’s life there’s a time when you switch to Feedburner, a highly useful RSS management and monitoring service. After it was bought by Google they’ve offered advanced statistics, in the PRO package for free, so not you have an even better reason to switch your old www.myblog.com/feed URL to them.
Some weblogs, like JohnPope’s did that from start, but that didn’t happen with all my weblogs. That’s when you realize that it would be nice to have a plugin that automatically redirects your old feed to the current Feedburner one.
Well, you don’t have to hold your breath anymore. Just grab the FeedBurner FeedSmith plugin from here, copy it in your wordpress plugin FTP folder and then activate it from your management plugins page. The options for FeedSmith are located in Options -> FeedBurner FeedSmith. Here you have to enter the Feedburner RSS URLS and the one for comments if you’ve switched them to Feedburner too.
The result may amaze you. My romanian blog, Ionutpopa.ro got from 44 to 169 subscribers in just one day.
