Frequently asked questions.
Is the page check really free?
+
Yes. There's no sign-up and no limit on how many pages you check.
What is Google Lighthouse?
+
Lighthouse is Google's open-source tool for auditing web pages. It's the same engine behind PageSpeed Insights and the Lighthouse panel in Chrome's developer tools.
What's a good score?
+
Lighthouse treats 90 to 100 as good, 50 to 89 as needing improvement, and anything below 50 as poor. Aim for 90 or above in every area.
Why does my score change each time I run it?
+
Performance scores vary a little between runs because of network conditions, server response times and third-party scripts such as ads and analytics. Run the check a few times and look at the overall picture rather than a single number.
Does it test the mobile version of my site?
+
The check uses Lighthouse's desktop settings. Mobile scores are usually lower, because Lighthouse simulates a slower device and network.
Do you store my results?
+
No. Your results aren't saved. To run the check, the address you enter is sent to Google's PageSpeed Insights service.
My score is low. What should I do?
+
Start with the issues the report highlights, since they usually have the biggest effect. If you'd like a hand, we fix performance problems for a living and offer a free call to talk them through.
