1) 51 subscribers on 1150 unique visitors = 4.5%
is this a good/bad/crap conversion rate for opt-in?
2) And what is a good conversion rate for a sales page instead?
I've 4% so far but only a few dozens of viewers.
3) Is the feedback from 200 visitors enough to decide if my strategy is working or not? How many visits on my landing or sales page are enough to understand how I'm going? 100 unique visitors? 1,000?
