If like me, you have started to see a referral source in your analytics of Redirect.viglink.com on or about April 1, it’s no April fools joke.
Instead, for my client, it turned out to be a change in the way the website PromoPro.com built their referral link.
While other companies may also use viglink, my client was getting a decent amount of traffic via PromoPro right up until March 31. It stopped, and an equal amount of hits started coming in from referral.viglink.com.
PromoPro is by no means the only company that has figured out how to make money by linking automatically to content. So your original traffic source may be any number of sites that happen to use the VigLink API to generate links to your site.
This may obscure the original source of the link making it harder for you to know the true referral source. I hope this tip helps you figure it out.
If you, dear reader, have something to add let me know and I’m happy to update this post.
