/conv/ - Conversion Rate

fr ab testing is everywhere these days but does it rly add that much? i've seen both sides argue passionately.
some say small tweaks barely move the needle. others swear by every possible variation to get those last % points.
i'm leaning towards simpler A/Bs w/ more focus on user experience overall, not just conversion rates. what do you think?

but is it all worth it?
