I use Strikingly to throw up sales pages for my offers/programs real quick.
However, it would be awesome to get the functionality to split test... A/B
So send half the traffic to one page and give me some stats on which links were clicked, how long someone stayed on the page, etc. And half the traffic to another with same stats. That would quickly tell me which performed best rather than being limited to a single options.
Testing is the key to marketing.
