Delay the execution of those scripts.
Those scripts are NOT required for browsers to properly render your page HTML document.
Flying Scripts is a free plugin that does this for you, if you haven´t used it before it´s pretty simple, make sure to watch the following tutorial...
I recommend adding a 5-second delay at the least. This will give your HTML document enough time to load.
You can do this with pretty much all the external scripts you see have a negative impact on your site´s performance.
You can also do this with internal scripts but this requires more testing on your part by loading the chrome devtool and disabling scripts one at a time, reloading the page, and browsing everything making sure nothing is broken.
A second option you can implement is NOT to show ads in the above-the-fold section of the page.
Lastly, you can always load them AFTER the HTML document loads, this has to be to resource prioritization. Basically, the ads will load normally, it's just that the browser won't queue the script until the page is ready.
Cheers!!
