Over the last few months I have noticed short spurts of referral traffic from Crowdflower.com. Crowdflower.com is a crowdsourcing “workforce” for things like human review of user generated content, but I can think of no legitimate reason for Crowdflower to be checking content at any of my websites unless companies like Facebook or Adsense are using the service.
Google searching for what and who actually uses Crowdflower does not bring up much and several discussions conclude that the traffic may just be referral spam, which I’m not sure I agree with.
After checking over 100 IP’s coming from Crowdflower.com, I have found that 0% of the visitors are located in the United States, and instead are coming from such diverse countries as Syria, India, Iran, Israel and Bangladesh. All of the visitors hit the front / home page, and 100% bounce without visiting any other pages.
I’m tempted to simply block all of these visitors as they clearly don’t care about my websites and arent doing me any good but am still looking to find who might be behind the traffic, since using Crowdflower.com is not free.
If you’ve seen this same influx of visitors coming from Crowdflower.com or if you know who or what companies might be using it, post a comment.
UPDATE: Rich Arnold, CFO and VP Strategy & Corporate Development at CrowdFlower reached out to me to explain what this traffic is that I have been seeing from CrowdFlower.com. During a good telephone chat Rich explained how the different types of jobs and tasks from Crowdflower work and thinks that my traffic was probably coming from one of Crowdflower’s ‘gold questions’ or ‘gold tasks’. These are questions or tasks with known answers used to test and validate the person doing the work. For example, a Crowdflower worker might be instructed to type in a certain search string or go directly to a site (like mine) and then be asked something specific about that site. Basically, how the Crowdflower worker answers that question determines if they are paying attention or not.
So it seems that although these bumps in traffic don’t do ME much good, they don’t do any harm either. Thanks Rich!
