Man, I've been messing around with different split testing tools for a bit now trying to squeeze out better conversions and man, some of these tools are total scams. Like I read about this 'auto split test' plugin that promises to optimize everything automatically but in reality it just eats up your traffic and then doesn't deliver any better results. You look at the data and it's just noise, no clear winners, and you end up wasting hours tweaking settings that don't even matter. Some tools I tried seem legit but then I see weird spikes or drops and realize it's just skewed data. The real deal is, if the data's skewed or not properly segmented, you're flying blind. I prefer manual A/B tests, but even then, it's a pain to get consistent results. What's your take? Any tools that actually do what they claim or are they just wasting time and risking your traffic?
