Website Performance Analysis Tool

Find out how your website performs with our performance tool.

Webpage Performance

Analyze the total loadtime, compressed / uncompressed size and number of resources of each webpage. Easily sort the results by maximum load time or file size to find out what to optimize.

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 each of these resources for the needed loading time and size and shows the total results and results for each ressource in the performance details. You can also find out if all resources load without errors, or there are any issues.

Resource Performance Details

The detail popup 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.

Website Performance Optimization Tips

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: http://refresh-sf.com/

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: https://www.wpbeginner.com/plugins/best-wordpress-image-compression-plugins-compared/

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.
