Wanting to automate the trackbacking process for articles linked to on the site, the ProDevTips blog went with a simple method using the Google Blog Search and Zend_Feed to parse the resulting feed from the search.

So Google Blog Search it is then. When you use the search you have the option of subscribing to it through an RSS feed. I did a link:url search and just copied the resultant feed URL. Using this URL it is possible to fetch for instance 10 results and display them through parsing the atom feed.

The example script queries the Google search, requests an output format of atom and spits back out a listing of the other sites/blog posts that link to any given article.
