You sell software, AI, and as-a-service products
A free trial is not revenue, and a sign-up is not a customer. Trakt follows each visitor from the ad click through trial to paid subscription, so you optimise on the conversions that pay rather than the ones that look good in the pixel.
Send the paid subscription back to Google and Meta as the conversion, not the free trial. Bidding then chases customers who convert to revenue instead of trial-tourists who never pay, which is the difference between growing MRR and growing a churn list.
B2B buying is slow. Someone clicks an ad, leaves, comes back from a search weeks later, then books a demo. Trakt keeps the thread across every session so the ad that started it gets the credit it earned.
Not every sign-up is equal. Trakt can weight the conversion by plan or contract value, so bidding learns to find your higher-value customers instead of treating a free plan and an enterprise deal the same.
Trakt records the click id on your own domain and sends conversions server-side. Your attribution does not depend on third-party cookies that Safari and Firefox already block.

Connect a store, run Trakt in shadow mode, and compare it against your ad account before you change a thing.
