Tools to check mobile speed performance

[jayoliverwright]

Hey Guys,

Looking at a site which has mobile versions of each page example: m.domain.com.au

Some of these pages have images which are over 1mb.

I want to quickly identify these pages with high image file sizes, any good tools which can do this?

Cheers.

You can use Google PageSpeed Insights:
https://developers.google.com/speed/pagespeed/insights/

And if your site is on WordPress then you can install this plugin:
https://wordpress.org/plugins/google-pagespeed-insights/

You also can use WebPageTest, GTMetrix, Pingdom Tools. Even one simply *nix tool as wget can make local mirror to site where you can see filesizes (command is wget -r -m http://m.domain.com/au ).

Alternative you can use desktop crawlers (like mine SEOSpyder) where you can see also images size in bytes.

Run Screaming Frog on your subdomains and check the Images tab in the report, then sort by image size and you'll find the large images.
