Lighthouse Settings

- Google PageSpeed Insights API key – In order to run audits, you need to enter your Google PageSpeed API key, if you don’t have it, see here how to get it.
- Language – Select language for Lighthouse reports.
- Strategy – Select if you want to get reports for Desktop, Mobile, or Both versions of sites.
- Notifications threshold – Set the threshold for notifications. If the score goes under the set value, the add-on will notify you.
- Automatically audit sites – If you want the add-on to automatically run audits, enable this feature.
- Automated audit frequency – If automated audits are enabled, here you can set how often you want them to run.
- Maximum execution time – Change the Max execution time if needed. If the Lighthouse reports are not being completed, increasing this value may help.
- Maximum script run time – Change the Max script run time if needed. If your scans do not finish completely and changing the Maximum Execution Time does not help, increase this value until you find the maximum allowed runtime.
- Throttling delay time – Change the Throttling delay time. Increasing this value may slow down Lighthouse reporting, but may help provide more accurate reports on poorly performing web servers.
