In April 2009, for example, FeedBurner was having problems reporting subscribers using the Google Feedfetcher service. Usually this problem is connected with one specific RSS reader or client. This is not actually a technical problem with FeedBurner, but by the feed readers and aggregators that report to FeedBurner, as FeedBurner collects and tallies from those partners. One frequent perceived technical problem with FeedBurner is the reduced number of subscribers being reported for the blogs using the service. Google 'retired' AdSense for Feeds on Octoand shut it down on December 3, 2012. Google shut down the APIs on October 20, 2012. On May 26, 2011, Google announced that the FeedBurner APIs were deprecated. One month later, two of their popular 'Pro' services (MyBrand and TotalStats) were made free to all users. On June 3, 2007, FeedBurner was acquired by Google Inc., for a rumored price of $100 million. As of October 5, 2007, FeedBurner hosted over a million feeds for 584,832 publishers, including 142,534 podcast and videocast feeds.

FeedBurner is a typical Web 2.0 service, providing web service application programming interfaces (APIs) to allow other software to interact with it.

Published feeds are modified in several ways, including automatic links to Digg and, and 'splicing' information from multiple feeds. Users can find out how many people have subscribed to their feeds and with what service/program they subscribed. Though it initially was not clear whether advertising would be well-suited to the RSS format, authors now choose to include advertising in two-thirds of FeedBurner's feeds.

Services provided to publishers include traffic analysis and an optional advertising system.
