Google is certainly a good web performance netizen contributing employee time, compute power, and technology to help make the web faster.
One of those contributions, Google PageSpeed Insights, is a free tool that helps you to implement web performance best practices. It analyzes the content of a web page and generates suggestions to improve the user experience of the web page and make it faster. A PageSpeed Score (0-100) is also generated; a higher score is better and a score of 85 or above indicates the page is performing well.
To use PageSpeed Insights:
Go to http://developers.google.com/speed/pagespeed/insights/
Enter the URL you want to analyze, and
click the “Analyze” button
It works by fetching the URL twice, once with a mobile user-agent, and once with a desktop user-agent. Google makes no bones about the importance they place on the mobile web and those recommendations are displayed first and front and center.
The PageSpeed analysis is based on 15 rules that represent the best practices for web performance optimization. The results provides a prioritized list of what to fix and it’s potential impact.
Here’s 3 quick suggestions for making the most of Google PageSpeed Insights.
1. Use your knowledge of your community and Google Analytics to determine if you need to pay attention to mobile site optimization now or just the desktop browser analysis.
2. Keep track of the PageSpeed Scores and suggestions over time.
3. Optimize for one suggestion at a time and re-run to verify positive results.
