High CPU load

Try installing a caching plugin.

Currently using W3 Total Cache, with the CDN option using maxCDN. Page caching and every other caching I have available is enabled. Any other suggestions?

You need to go over your site. Almost 2MB is from images alone. With the rest of the page objects it is a joke. Think of the download times…
Then there is the sheer number. My script reported 93 total images.
Too many scripts. And content seems to be pulling from a number of external websites which if that is processed Server-side it would kill the CPU.

Right… Most of the images are hosted on a CDN, so that shouldn’t be affecting my CPU resources much. I’m not super savvy on all this stuff – I can do CSS editing, but honestly don’t even know where to start.

Can you give me any specific direction as to what to do?

Thanks.

First, I would not ignore anything just because it is being served from elsewhere. It still directly effects the site visitor negativly. Unless you do not care about having site visitors. And its part of the total picture anyway.
Google for “website analyzer” and choose one. The better ones should be able to point out what needs to be changed for optimization.
Then check the site against: https://validator.w3.org/
and you will probbly find many coding errors that need to be fixed. Don’t worry about the small ones for now.
Finally you need to change the structure of the site for visitors. Again unless you do not want visitors to your website. (They always seem to be the forgotten people) Your main page takes 30 PageDowns to reach the bottom. Besides that much content on one page causes the problems I stated before, research has shown visitors will not pagedown that many times. 4-6 should be max. And reduce the amount of ads on the page. When you have too many, they ALL just get ignored.
