There is a small possibility that Convertize can affect the speed of your website. The Convertize Pixel is only 25 kb in size and loads within 25 to 50 ms, and in order to ensure the fastest possible loading times, Convertize introduced Lightning Mode.
To monitor any effects Convertize might have on the speed of your website, we recommend you run a loading time test before and after installing the Pixel.
To do this, go to pingdom.com, enter your website URL and click on “Start Test”.
Then, compare the speeds.
We recommend you run more than 1 test, as many different things can affect the result. For a more accurate measure, run several tests and take the average.
