Shopify Collabs

The app is ok for managing your own collabs.

But collabs that you get from Shopify, i.e. collab applications are mostly SEO parasites. All they did about a year ago - get your coupon, add it to a coupon website and make money of your on your brand.
Shopify tried to deal with this.

What they do now is create a website that has some info from your website and add their collab link there. Some people click on their page found in Google and that's it - they make money of you. The more traffic your attract - the more well known your brand is, the more they will make money of your. BUT THEY WON'T BRING YOU TRAFFIC or any extra money. They will simply reduce your margins.

So app itself if ok, but most collabs applying via Shopify are scammers.

Also, if you have a subscription model, app does not correctly attribute sales.
