For the best results using FeedBurner with your self-hosted WordPress site, we recommend the FeedBurner FeedSmith plugin (originally authored by the legendary Steve Smith). The plugin will detect all ways to access your feed (e.g. http://www.yoursite.com/feed/ or http://www.yoursite.com/wp-rss2.php, etc.), and redirect them to your FeedBurner feed so you can track every possible subscriber. It will forward for your main posts feed and optionally, your main comments feed as well.
The plugin is currently compatible with downloadable WordPress versions 1.5 through 2.5. (Please note that “tag” feeds in later WordPress versions are not supported.)
Download the plugin, then follow the instructions below to begin forwarding all WordPress feed traffic to your FeedBurner feed.
- Copy the plugin file, FeedBurner_FeedSmith_Plugin.php into your default WordPress plugin directory, wp-content/plugins/ .
- Activate the plugin by logging into your WordPress administration area, clicking Plugins, then clicking Activateat the end of the “FeedBurner FeedSmith” row.
- In the WordPress administration area, begin the configuration by clicking Options and then the FeedBurner FeedSmith sub-option.
- Follow the links to create your FeedBurner feeds, or if they already exist, simply fill in their URLs in the boxes provided.Note: If you currently use the old, 2005-vintage version of the Ordered List FeedBurner plugin that generates a FeedBurner-specific URL (an example: www.yoursite.com/feedburner_838196/), that URL is no longer available or necessary. You will have to reset your FeedBurner feed’s Original Feed address to now use your standard blog feed address. Additionally, you should examine any .htaccess files that control access to your WordPress installation’s content and remove any existing references that forward or redirect your feeds, as these references will no longer be necessary.
- Verify your URLs in the text entry fields, and click Save.
Now all of your WordPress feed traffic should be redirected to FeedBurner.
To deactivate automatic forwarding of your feed traffic to FeedBurner, deactivate the plugin via the Plugins section of your WordPress Administration control panel.
