Honestly I've tried so many split testing tools over the years and most of them just add more headaches than they solve. You get promises of easy data, real-time stats, blah blah but then you're stuck with tools that crash, give you wonky numbers, or just plain refuse to work unless you jump through hoops. So I finally started digging into the data myself and stopped relying on these fancy tools. Turns out the best thing is a simple spreadsheet with A/B test data logged manually. Yeah I know, old school but it's way more reliable and faster to see what actually moves the needle without waiting for some flaky dashboard to update. Plus, I keep a little note on every change I make so I can correlate stuff better. The big trick is to focus on small tests, keep variables minimal, and just track everything in one place. It's dull but it's honest and I don't get these weird glitches that mess up my numbers. Anyone else just give up on these overhyped tools and go back to basics?
