have a webapp where I make http post requests and I wanted to improve the form where users post advertisements. Now when I improved it, how do I actually measure or know that I made an "improvement"? The load time is quicker, the http requests are fewer, but how to I measure usability?
The prior version of my ad posting page looked like this and was successful.
The new version looks like this and gets better results in tests.
Should I accept my own redesign already, or should I improve it more?
