How many people subscribed to your RSS feed?

Here's a quick tip to estimate the number of your RSS subscribers. All you need is access to the web server logs.

Let's filter the logs for the RSS file name (in my case it's atom.xml):

cat access.log | grep atom.xml

When looking through my logs, I've spotted the following entries:

"GET /atom.xml" 304 0 "Mozilla/5.0 (compatible; inoreader.com; 9 subscribers)"
"GET /atom.xml" 304 0 "Feedbin feed-id:1524967 - 5 subscribers"
"GET /atom.xml" 304 0 "Feedly/1.0 (+http://www.feedly.com/fetcher.html; 16 subscribers; like FeedFetcher-Google)"

As you can see, Inoreader, Feedbin and Feedly put the number of subscribers right into their HTTP requests, hidden in the "user agent" string. In total, there are 30 people using those services that have subscribed to my blog. I avoid marketing, so that's actually more than I've expected.

Keep in mind that getting the actual number is pretty much impossible, as none of the other feed readers reveal the subscriber count. This method is good enough for a rough estimation, though.
