So you're reviewing a campaign, putting together a few thoughts on how it went and you just can't seem to get the numbers to match up. Why won't clicks equal visitors? Why does Google Ads report conversions differently to Analytics? What is going on here. Which platform should I trust?
Google does a pretty good job of explaining potential reasons for data discrepancies and lots of links to drill down into each particular issue. So rather than repeat them all, I've included links to the relevant sections below.
