I visited the ClickFunnels.com site and now their ads and glowing testimonials are following me everywhere! Boy do they retarget! I can't seem to find an independent review that isn't an affiliate link. They say that several ecommerce merchants have switched from the more mainstream platforms and quadrupled sales or something like that. Anyone here have experience with it? While it appears really user friendly I am wondering it it can handle the demands of a mid-sized Shopify ecommerce business.
