We’ve built highly optimized funnels for hundreds of businesses, using dozens of rounds statistically-driven A-B testing that have increased website revenue from existing traffic in some cases more than 10-fold. In one recent case a small affiliate business incorporated several of our sales funnels on their website and grew revenue from $2500/month to more than $29,000/month in just over a year.

If you bypass the popup, you get to the homepage. It’s laid out very clean and with buttons at the top that very clearly help you find other things you need on the site. The ads that populate are also helpful in getting you to click, therefore generating revenue for their company and closing the sale.
You can absolutely do that. If you want to upgrade to a paid plan to get some of the features you want, then you can switch at any time through the My Products option in your account or with the help of a GoDaddy Guide. Once you upgrade your site will have all the same customizations and work that you've already put in place, just with the added features. See Website Builder plans and pricing for more info.
