Here is How our pixel work on your website.
We are calling our js file when the entire HTML page request serves on the browser side. So it will get loaded at last & after that, it starts calling the API asynchronous way. Never disturb your website speed load time majorly.
Our js & CSS file is already a minified file. Both are loaded when fully HTML gets rendered on the client-side. So when Google bot or any client browser visits your site, first they will get HTML content & lastly, we load our pixel js async away.
This way, it will never block anything on the client-side browser.
