API key

It looks like Google has changed this process a bit since I wrote the documentation for this plugin.

You will need to create a “Browser” key. After selecting that it will allow you to enter IP addresses, but this field can be left blank for most users.

I have updated the documentation with this plugin tonight to show the new process for obtaining an API key.

The docs are also now available online here: https://mattkeys.me/documentation/google-pagespeed-insights/
