One of the key factors Google considers when ranking web pages is page load speed. A fast-loading website enhances user experience and increases the likelihood of appearing in top search results. To help website owners analyze and optimize their site’s performance, Google provides a free tool known as Google Page Speed Insights (PSI). This article explores the significance of Google Page Speed Insights, how it works, and the best practices for optimizing your website’s performance.
What Is Google Page Speed Insights?
Google Page Speed Insights (PSI) is a free web performance analysis tool provided by Google. It evaluates the loading speed and overall efficiency of a webpage and assigns a performance score between 0 and 100. A higher score indicates better performance, with Google’s ideal target being 90 or above.
PSI analyzes both desktop and mobile versions of a website, identifying key performance issues and providing actionable recommendations for improvement.
How to Use Google Page Speed Insights
Step 1: Accessing the Tool
Go to the official Google Page Speed Insights website.
Step 2: Entering Your URL
Copy and paste your website’s URL into the provided field and click Analyze.
Step 3: Viewing Results
Once the analysis is complete, you will see performance scores and detailed metrics for both mobile and desktop versions of your site.
