Google Pagespeed Insights requires a Google API Key. Keys are free and can be obtained from Google. In order to get a key, you will need a Google account such as a GMail account. If you do not already have a Google account you can create one here: https://accounts.google.com/SignUp.

1. Navigate to https://code.google.com/apis/console
2. Login with your Google Account (Create a Google account if you do not have one)
3. Create a new API Key and enable the Google Pagespeed Insights API* (see note about restrictions)
4. Paste your API Key into the Options page of Google Pagespeed Insights for WordPress

• Try first creating the API key without any ‘restrictions’. In my testing there seems to be a bug with using restricitons with the Pagespeed API.

Requirements

• Google API Key https://code.google.com/apis/console/
• WordPress 3.6 or Newer
