posthog vs google analytics.
Both are free for a small site. They answer different questions. Google Analytics is built around marketing: where did people come from? PostHog is built around behaviour: what did they do when they got here, and where did they give up?

the fair bit
when google analytics wins
If you run Google Ads, Google Analytics talks to them directly, and most marketers already know their way round it. If you mainly want to know which campaigns bring people in, it does that well and costs nothing.
when posthog wins
when you want to know why
If people are landing on your booking page and not booking, PostHog shows you why. Watch the visits back, see the step where they stop, and ask a one-question survey. For small businesses selling online, that’s usually the more useful question.
can i have both?
yes, but think about consent
Plenty of sites run both. Each needs consent for its cookies in the UK, and two tools means two sets of numbers that never quite agree. If you’re starting fresh, I’d pick one.
questions
the honest answers
Is PostHog GDPR friendly?
It can be: pick EU hosting, ask for consent, and mask personal details in recordings. How you set it up matters more than which tool you use.
How do I add PostHog to WordPress?
There’s a step-by-step guide here, using my free Pressed Hog plugin.
