I’ve had ~200 visitors to a small landing page test so far, but the confidence interval is still 0%. How many visitors and clicks do I need to have a confidence interval be calculated?

Chatted with Unbounce folks. Since I have a page with 4 variants, the suggestion was that the confidence interval should start calculating around 500-1000 visits. I am going to eliminate a couple of the variants to speed the process up a bit and see how that goes.
