Google PageSpeed Insights is a great tool for developers to identify ways to make their websites faster and more mobile-friendly. I tend to check the our websites with PageSpeed during development phase to identify issues early on which can impact the performance of our AEM websites.

Out of curiosity, I checked the PageSpeed scores of other AEM/CQ implementation that I am aware of and compiled the list. The best performing AEM sites list below is based on PageSpeed score only.

PageSpeed Insights analyses and measures the performance of a web page for mobile and desktop devices by fetching the url twice, once with a mobile user-agent, and once with a desktop-user agent. Based on the analyses it assigns a score which ranges from 0 to 100 points. A higher score is better and a score of 85 or above indicates that the page is performing well.

Since the performance of a network connection varies considerably, Page Speed Insights only considers the network-independent aspects of page performance: the server configuration, the HTML structure of a page, and its use of external resources such as images, JavaScript, and CSS to calculate the score. The absolute performance of the page will still be dependent upon a user’s network connection.

Here are the Page Speed scores of the sites running on AEM/CQ:

These score are not permanent as Google continually add new rules to improve the analysis. Score will also change as companies pushes updates to their websites.

Do you know any other public website running on AEM/CQ5? Please submit it using the comments section and I will update the table.
