How to choose the best cookie consent platform
"Best" depends on what you might have to prove, and to whom. A banner that collects clicks but can't show what someone agreed to is worse than nothing. It creates a record you can't defend.
Here's what to test during an evaluation, roughly in the order it matters.
1. It finds cookies you didn't know about
Most sites set cookies nobody chose. An embedded video player, a chat widget, a marketing script added for one campaign and never removed. If the platform expects you to type that list in by hand, it'll always describe a site that no longer exists.
Test it: run a scan before you configure anything, then check the result against your browser dev tools on a few real pages.
2. It shows the right thing in the right place
Consent rules aren't the same everywhere. In the EU, non-essential cookies wait for an opt-in. Several US state laws work the other way round, built on opt-out and on honoring a browser signal. Applying the strictest rule everywhere is the usual shortcut, and it quietly costs you analytics coverage in markets that never asked for it.
Test it: load your site through a VPN in two or three regions you actually sell into.
3. It can prove consent later
You don't just have to collect consent, you have to be able to show you got it. That means a record tying the decision to the banner version and the categories on offer at the time, not a single true or false.
Test it: ask to see one consent record end to end, and check whether you can export the log.
4. It doesn't fight your tag manager
Consent has to be set before tags load. Otherwise you get the worst version of this: a banner that works perfectly while the tracking already fired. Check the load order the platform recommends, then watch the network tab and make sure nothing non-essential goes out before someone clicks.
5. You can find out what it costs
A platform you can't budget for is hard to sell internally. Published prices, a real free tier and clear limits mean you can change your mind later without a renegotiation.
Frequently asked questions
Is a free cookie consent tool good enough?
For a small site with a handful of cookies, often yes, as long as it still stores consent records and blocks tags before consent. What usually pushes people onto a paid plan is scheduled rescanning and geo-targeting, not how the banner looks.
Do I need a cookie banner if I only use analytics?
Analytics cookies count as non-essential, so in the EU they need consent before they're set. Some analytics setups avoid cookies altogether, which changes the answer, so check how yours is configured.
How often should the cookie scan run?
Every time your site changes, and on a schedule anyway. Monthly is a sensible floor for a site under active development, because new cookies show up through third-party scripts without anyone deciding to add them.
