RSS ad network and delivery platform Pheedo last week released the first in a series of "Pheed Read" reports providing a view into RSS usage patterns, based on the activity on its network of advertisers and publishers in June and July (via paidcontent).

Study findings include the following: Tuesday is the most active day in RSS readership, feed retrieval and click-throughs, and Saturday the least active; also, click-through rates (CTR) fluctuate significantly depending on the day, differing more than 70 percent from Tuesday to Saturday.

In addition, "Morning scanners" view the most content, and late-night readers click through more, with CTR fluctuating 7-11 percent depending on the hour of the day; led by Bloglines, 70 percent of Pheedo managed feeds are read by only five news aggregators.

Bloglines is followed by Firefox, Thunderbird, NewsGator and Sharpreader. Together they are used by almost 70 percent of people subscribing to Pheedo-managed RSS content.

The report is available at the Pheedo site: here.
