Question about Image Optimization and File Size -- Does it really matter

[EricVallee]

I was using Moz's guidelines (https://moz.com/learn/seo/page-speed) to reduce the file size of my pages to improve load speed, but I'm not sure it really makes much of a difference.  On this page https://www.mtecorp.com/cad/MAPP0006A002/, the file size is 710KB and it's Google Page Insight Score is 84 on desktop and 66 on mobile.   On this page https://www.mtecorp.com/cad/SWNW0130E/, I got the image size to 227KB and its Google Page insight Score is virtually the same,  87 on desktop and 62 on mobile.

Any ideas if it is really worth the time to get images down? (or maybe it doesn't matter if it is less than 1,000KB.

Hi Eric,

Page speed insights report is not only about the page size (in kb). Its about when users can interact with the page vs time.
Checking the 2nd page, it looks like your server is one and render-blocking resources are the main problem.

There are some WordPress plugins that usually take care of that. I'd suggest taking a look at the W3 Total Cache plugin and its option to minify resources.

Hope it helps.
Best luck.
Gaston

Thank you Gaston.  I had WP-Rocket on my sight, which offers some of the same abilities.  I will try using that.  Thank you for your guidance.
