Customer Reviews RSS feeds

So AppAnnie says there are 208 reviews total? What is the maximum number of reviews that you get per country? Each feed request may be limited by a maximum number of entries. It may also be limited by age of entry. The expectation is that a feed is just the most recent. If a given feed only returns 10 entries at a time, and you check a feed once an hour, and there are 11 new entries per hour, then you will miss 1 entry per hour. An established system like AppAnnie probably saves each entry in its own database. You should do that too. Also, don't forget to do HEAD checks with an "If-Modified-Since" header. That is very important with a feed and should keep you from hitting any IP or frequency restrictions.

I guess I stand corrected. I've never seen that before.

It looks like iTunes is limited to a maximum of 10 pages. In practice, it doesn't matter because in addition to "next", there is also a "last". You would keep following the "next" links until your current URL is the same as the "last" URL. Maybe that is 10 today or 20 tomorrow.

The feed URL you posted has 51 entries, not 50. There is no counter in the XML content and you can't assume any specific count. You just have to process each /feed/entry node.

There is no such thing as a page in an RSS feed. That would total 500, an App Annie says you only have 208 total. That doesn't add up.
