There is a small possibility that Convertize can affect the speed of your website. In order to monitor this 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.
