Strategies for dealing with copycat products?

Here’s what we’ve found so far. Basically, you need to report each copycat product listing you find in a different way, depending on the website:

After reporting

We track of the URLs that we find and report so we can check back on them to make sure that the products really are gone. If nothing works, the next thing we do is contact the web host (you can find that through https://www.whois.com/ if it’s not obvious).

Does anyone else have good tips?

You can use a visual montoring service like visualping.com to know when the listing has changed.

Though for marketplace situations there can be constant changes by the platform and not the copycat seller so there would be false positive notifications.

So you’d want the notifications to a specific email for when reviews happen.

Could also be useful for noting if seller behavior or tactics change after a complaint.

More complex roll your own with something like https://github.com/dgtlmoon/changedetection.io (python, apache2.0 license or https://github.com/huginn/huginn (ruby, mit license)
