MainWP Lighthouse WordPress Extension is used for measuring the quality of your websites. It uses the Google PageSpeed Insights API to audit the performance, accessibility, and search engine optimization of your WordPress sites.

The MainWP Lighthouse Extension is used to automatically measure the quality of your Child Site(s). It audits the performance, accessibility, best practices, and search engine optimization of websites connected to your MainWP Dashboard.

This Lighthouse WordPress extension uses the Google PageSpeed Insights API which runs a barrage of tests against a Child Site and then generates a report on how well the Child Site did.

From here you can use the failing tests as indicators of what you can do to improve your website quality.

Lighthouse WordPress Extension Saves you Time!

We tested 30 websites individually and found out that it took 32 seconds for each website costing us 16 minutes for 30 websites.

Then we give a test to our Lighthouse plugin and it took only 10 seconds per website resulting in 5 minutes for 30 websites, saving us 11 minutes.

Do the Math for Hundreds of Child Sites!

Moreover, with the MainWP Lighthouse Extension, you don’t need to open 30 tabs to test and then look for what stats are on which website. Such a hassle & time-consuming!
