This is one of the most common concerns we get from publishers who are thinking about using Ezoic's platform. Whether they've hand-coded the site page-by-page, use custom CSS and HTML, or have half the pages built one way and have half the other - the question is: How in the world is your platform going to be able to manage that?!
Well, you're in luck. It does not matter how the site was built. Whether it was hand-coded in 1999 or uses a modern CMS such as WordPress; as long as the site can be viewed in a browser, it will most likely work with Ezoic.
We've spent over 4 years developing the technology, and without wanting to toot our own horn, it's smart! The system is able to look at a webpage, separate the content (text, images, widgets, etc) from the CSS and HTML, and rearrange the content into the experimental layouts.
This is a simplified way of explaining how it works, but it's the easiest way to show that it does not matter whether or not you have custom CSS or use Dreamweaver; Ezoic can work with almost all sites.
Still not convinced?
Why don't you give it a try and see for yourself whether or not the platform will work for your site? There's no risk to trying. Typically, publishers using Ezoic's layout improvement technology increase their revenue 2x while improving usability on all devices.
If you're not happy with the results, you can turn the platform off, or return to the original site. Your original site is never affected in any way.
