Google has updated its toolbar for Internet Explorer and Firefox with a sharing feature, which enables user to share any page to a variety of social networks. Additionally, My Location is now out of Toolbar Labs and official on the Google Toolbar.

Meanwhile, if you have the RSS feed on your blog set up through Feedburner, it just got a heckuvalot easier to send your posts to Twitter. Simply go to your Feedburner account, select the feed you wish to Tweet, and then click on the “Publicize” tab to set things up.

The social sharing updates for both the Google Toolbar and Feedburner will use the new Google URL shortener, goo.gl.

If you use AdSense for Feeds or Google Feedburner to manage RSS feeds on your site – and you use Google Analytics – then you’ll be glad to know Google is connecting the two. You’ll be able to iew click data for your feeds services in Google Analytics.

Analytics will tag the Source as “Feedburner” and the Medium as either “feed” or “email” depending on how the feed item was sent out. Content will show the endpoint (i.e. Google Reader, Yahoo! Mail). Check for the data under “All Traffic Sources” and “Campaigns” views in Google Analytics.

Google Analytics gathers this data when item clicking is turned on in Feedburner. So you’ll need to have that enabled for this to work – or not if you don’t.

Advanced analytics users can also configure their Analytics tracking within their Feedburner settings.

If you’ve ever clicked on a link in your RSS reader and that link is associated with a site that uses Feedburner, you’ve probably noticed that the initial URL to appear in your browser’s address bar was related to the feed and not the final URL. That’s because Feedburner uses the URL to track the click.

The redirect was a 302, a temporary redirect. But now Feedburner is updating the URLs to be permanent 301 redirects.

Feedburner, which is owned by Google, says that the reason for the change was that some search engines index the feeds, which affects the popularity of a site.

If you use Feedburner, you don’t have to do anything special. The update is automatic.
