Are Twitter members more likely to comment on blogs?
As we know, I obsess over my blog's traffic. I've kept a close eye on the traffic that Twitter sends here for a while, and I've noticed that it's been growing every month since last September. I've also noticed that there seem to be more comments here in the past few months, and my guess is that as more traffic is coming from Twitter, that more of those people are commenting.
So I decided to dig in and see if the stats supported this theory.
Here's the traffic that Twitter sent to my blog for each month since September, and the average number of comments per post I had for each month(in parantheses):
September - 162 (10)
October - 342 (7.6)
November - 554 (7.5)
December - 1,079 (14.7)
January - 1,349 (11.8)
February - 1,377 (13.2)
Now when I first looked at these numbers, I wasn't that impressed. If you look from September to February, traffic from Twitter has increased about 800%, but comments per post only increased by about 30%.
But then I remembered that the avg comments per post figures include the Top 25 posts. This is important to note for two reasons: 1 - The Top 25 posts get far fewer comments than the rest of the blog (around 4 comments per post, compared to 11 per post for all of the blog), and 2 - I rarely promote new Top 25 posts on Twitter, while I do promote almost all of the remaining posts there.
So I decided to remove the Top 25 posts and comments from the totals, and see what the stats looked like then:
September - 162 (8.7)
October - 342 (9.7)
November - 554 (9.9)
December - 1,079 (18)
January - 1,349 (14.5)
February - 1,377 (15.5)
Now you see traffic from Twitter is up about 800% since September, and avg comments per post have almost doubled.
Is all this enough to suggest that Twitter members that come here are more likely to comment than other visitors? I'm not sure, avg comments per post is definitely increasing, but referral traffic from Twitter is increasing at a much faster rate.
What have you noticed from your blog's traffic? Does it seem that people coming from Twitter are more likely to comment on your posts?
