Pagespeed optimization with SERPtimizer website performance test

Webpage loading times overview

With our website performance test, the loading times of your website are listed directly in the overview. Loading speeds, transferred and extracted data sizes of your subpages are conveniently displayed here so that you can see which pages need to be further optimized right away.

Resources Performance for JavaScript, Images and CSS Files

Nearly every website includes resource files such as JavaScript, images and CSS. Many of these resource files must be loaded before the page can be displayed. SERPtimizer analyzes within the website performance analysis each of these resources for the needed loading time and size and shows the total results and results for each resource in the performance details. You can also find out if all resources load without errors, or if there are any issues in need of your attention.

Resource Performance Details

The detail popup of the pagespeed tool helps users to discover all requests for a single page in detail. This information includes the link of the resource, file type of the resource, time to load, transferred size and extracted size. The Popup will also provide the HTTP result code of the transfer and if the resource uses GZIP compression or not.

How fast does the page speed of my website have to be?

For a good user experience, it is always advantageous if the page speed, or the loading time, is displayed in the pagespeed tool as low as possible.

Long loading times have a negative impact on the rating on Google but also on the normal visitors, as they might get annoyed quickly by long page speed loading times and bounce when their patience has reached its limits. At almost 10 seconds and above, visitors usually start to lose focus and attention to the website. This can quickly lead to a direct bounce decrease the likelihood of returning tremendously. The page speed of a website is currently ideally less than 2 seconds.

Tips for Website Performance Optimization after page speed test

Minify Resource Files

To minifying resource files, multiple techniques are used:

  • Removal of not required characters like blanks or line breaks
  • Removal of Comments
  • Renaming of function names and variables to short identifiers

For WordPress, plugins like Autoptimize minify these resources automatically:

To minify a resource manually, you can use websites like:

Bundle Resource Files

Many individual resource files cause an overhead when loading, which delays the loading time of the web page. You should bundle resource files to minimize the number of http requests. Use the WordPress plugin Autoptimize mentioned above.

Image Optimization

Many image optimization plugins with different techniques exist. An comparison of some of these plugins can be found here:

GZIP Compression

Use GZIP compression to keep file sizes smaller, especially for HTML, Javascript, and CSS files. That way these resources can be reduced to about 1/5 of the original size. Such optimisation is activated in the web server or content management system and should not be missing for any of these resource types.

Fortunately, SERPtimizer shows you for which resources GZIP has already been activated and where you still need optimization.
