Why is my traffic lower than Google Analytics said?

Four reasons, and you can check three of them in about ten minutes.

We filter more bots, and we show you the count. Feasible runs five classification checks and refuses anything that matches - crawlers, headless browsers, datacenter addresses, monitors, AI scrapers. Open the health panel and read the drop counts by reason. On a site with any backlinks at all, that number is usually large enough to explain the whole gap on its own - and unlike every other tool here, you can read the exact count.

The words mean different things. A “visit” here is one sitting that closes after 30 minutes of inactivity. A “session” elsewhere may restart on a campaign change, on midnight, or on a different timeout. Compare pageviews to pageviews before you compare anything else - that’s the one definition everybody shares.

The blocking is different. Blocklists carry different hostnames, so the two scripts don’t get blocked by the same people. Somewhere around 13% of visitors block something, but that varies enormously - a developer blog and a recipe site are not the same audience, and neither is a mobile-heavy one. If it matters to you, serving the script from your own domain narrows the gap.

GA4 thresholds and samples its reports. When a report might identify individuals, rows are withheld, and large date ranges get estimated rather than counted. Google’s own documentation says the BigQuery export is the guaranteed-unsampled route. Feasible discloses sampling when it happens, with a badge and a one-click “show exact numbers” - so the two tools aren’t hiding the same amount from you.

Then the boring one: check the time zone on both sites and check you haven’t left a stray tag on one of them. If the numbers still don’t reconcile, the general version of this question has the rest.
