After integrating the TikTok pixel on Magento 2, you may notice a decrease in page loading speed, as the pixel adds additional requests that can slow down the site. To minimize this effect, it is important to optimize its work correctly. I recommend using the solution from Amasty. This extension for helps to significantly speed up the loading of the site by correctly setting up the transfer of pixel data without affecting performance. It automatically adjusts the pixel loading so as not to interfere with the speed of the pages, and ensures that all events are tracked without errors and delays.
