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.
Video backgrounds and animations are no problems whatsoever. This website builder gets SEO right, too. Portfolio pages, in particular, turn out really good, and most importantly, without being difficult to create. They have many business-focused apps (e.g. for hotels or restaurants) that can make your life easier if you are in one of these industries.
