Website Speed and Performance Optimisation

Speed benchmarking services help you test the performance of your website pages. They are a vital tool when optimising your website as their reports will tell you the size of your web pages, the time it takes pages to load, and the total number of requests.

The great thing about these services is that they will show you exactly what is slowing down your website, whether it be images, a particular piece of Javascript, or the ping time between your server and their test centre.

Reports also show you exactly what you need to do to rectify an issue. If you follow their recommendations, your pages will load faster. This ensures a good experience for your visitors, will increase conversions, and it will improve your ranking in search engines.

* Unless otherwise stated, all services listed on this page are free to use.

Sucuri Load Time Tester

Sucuri is best known for their security products and services, however they also provide a free test that shows you how long it takes to connect to your site and for one page to fully load.

One of the most interesting things it highlights is the “time to first byte”. They define this as how long it took for the content to be sent back to browser to start processing the page.

Whereas many speed testing services process a report based upon the performance from one data centre, Sucrur's load time tester will test a page against over a dozen servers around the world. This will give you a more accurate picture of your website speed.

You will undoubtedly love the waterfall, performance review, and content breakdown reports, that Web Page Test provides.
