How do you decide which pages on your site deserve your time after launch?

After a launch, most makers I talk to put everything into the product and treat the website as finished. A few months later they have 30 pages, almost no search traffic, and no idea which pages are working.

What I’ve seen help is picking the 3 or 4 pages that already get a few impressions and fixing only those, instead of writing more. It feels slower, but it’s usually where the first real traffic comes from.

I’m curious how other founders handle this. Do you review your site pages on a schedule, or only when something looks wrong? And what tells you a page is worth improving rather than deleting?
