Optimize Google Page Speed Insights

How to Score 100/100 Speed at Google Page Speed Insights to Improve SEO

Here are 10 factors that need to be considered in order to optimize Google Page Speed Insights:

  1. Avoid landing page redirects
  2. Prioritize visible content
  3. Reduce server response time
  4. Enable Compression
  5. Leverage browser caching
  6. Minify HTML
  7. Minify JavaScript
  8. Eliminate render-blocking JavaScript and CSS in above-the-fold content
  9. Optimize images
  10. Minify CSS

Avoid landing page redirects in order to optimize Google Page Speed Insights

Redirects trigger an additional HTTP request-response cycle and delay page rendering. In the best case, each redirect will add a single roundtrip (HTTP request-response), and in the worst it may result in multiple additional roundtrips to perform the DNS lookup, TCP handshake, and TLS negotiation in addition to the additional HTTP request-response cycle. As a result, you should minimize use of redirects to improve site performance.

Prioritize visible content in order to optimize Google Page Speed Insights

To make pages load faster, limit the size of the data (HTML markup, images, CSS, JavaScript) that is needed to render the above-the-fold content of your page. There are several ways to do this:

  • Structure your HTML to load the critical, above-the-fold content first in order to optimize Google Page Speed Insights
  • Reduce the amount of data used by your resources

Reduce server response time in order to optimize Google Page Speed Insights

You should reduce your server response time under 200ms. There are dozens of potential factors which may slow down the response of your server: slow application logic, slow database queries, slow routing, frameworks, libraries, resource CPU starvation, or memory starvation. You need to consider all of these factors to improve your server’s response time.

Enable Compression in order to optimize Google Page Speed Insights

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

Leverage browser caching in order to optimize Google Page Speed Insights

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Minify HTML in order to optimize Google Page Speed Insights

Minification refers to the process of removing unnecessary or redundant data without affecting how the resource is processed by the browser.

Minify JavaScript in order to optimize Google Page Speed Insights

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.

Eliminate render-blocking JavaScript and CSS in above-the-fold content in order to optimize Google Page Speed Insights

You should avoid and minimize the use of blocking JavaScript, especially external scripts that must be fetched before they can be executed. Scripts that are necessary to render page content can be inlined to avoid extra network requests, however the inlined content needs to be small and must execute quickly to deliver good performance. Scripts that are not critical to initial render should be made asynchronous or deferred until after the first render. Please keep in mind that for this to improve your loading time, you must also optimize CSS delivery.

Optimize images in order to optimize Google Page Speed Insights
