## How we research

How we research [Read the ranking →](/best) 

Every ranking on this site is research-based. Here is exactly what that means, so you can judge the work rather than take it on faith.

### What we do

* Read the vendor's own documentation, feature pages and pricing pages, which are the source of truth for what a tool is, what it does and what it costs.
* Verify every price and trial against the vendor's pricing page, and record the date we checked it. Prices go stale silently, so each one carries an "as of" date.
* Read what long-term users report in public: Reddit threads, G2, Capterra and Trustpilot. This is where reliability, support and lock-in show up, which a feature list never admits to.
* Weigh those against the vendor's claims. When users and the vendor disagree on a fact, the vendor's own current page wins for facts; the users win for experience.

### What we do not do

We do not run these platforms on live campaigns, and we do not pretend to. We do not publish first-hand performance numbers we did not measure, invented case studies, or star ratings dressed up as data. If a claim is not something we read and can point you to, it does not go on the page.

### How we rank

The ranking is ordinal, not scored. There is no 1-to-10 rubric to defend cell by cell; instead each tool gets a single, non-overlapping reason it is worth your time. For a paid-traffic seller, the order reflects five things, roughly in this weight: checkout conversion features (order bumps, one-click upsells), split testing that respects the ad platform, payment flexibility and routing, total cost at real volume, and how much independent evidence backs the vendor's claims.

### How often we revisit

We re-check the money pages every 90 days, and sooner when a vendor changes pricing or ships a feature that moves the ranking. Each page carries a changelog so you can see what changed and when.

### Corrections

If we have a fact wrong, tell us and we will fix it and note the change. Email [editor@checkoutscale.com](mailto:editor@checkoutscale.com).

We rank the platforms that build the pages and host the checkout for teams running paid traffic: order bumps, one-click upsells, split-testing whole checkouts, different checkouts per traffic source, and payment routing for high-risk verticals.
