How to find out the weight of each page on the site?

Question

Search Engine Optimization

Good afternoon, tell me how you can find out the weight of each page on the site? This means the weight in kb, or mb =)
I know page by page, maybe gtmetrix, but what if you need to know the weight of 1000 pages?
Share your knowledge please.

Answer 1

Alexey, a question, maybe I do not understand correctly what you want.
You need page weight, which:
A) gets the user/browser after loading the site, i.e. already compressed HTML
B) the actual weight of the pages BEFORE running all sorts of scripts to optimize the code / weight
If the first option, then the Screaming Frog SEO Spider program may be suitable.
If I'm not mistaken, it shows the first version of the page weight (see screenshot).

If you don't have a program, then provide the sites, I'll take the data and send it to you.
