Strain Envy review for EcomRise Post Purchase Upsell

How on earth everyone finds this "easy" to install is beyond me. You have to code every single page on your website. How is that easy? 4 years I've never had to code anything or hire someone to do it. And for what? So Google can collect more data and make more money? Why would I pay for this? It's not something I can handle myself and hiring someone is not an option for this should be simple task.
