Is it possible to insert a script from Adsense (adsbygoogle.js) once?

Question

Google Adsense

There is this code:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

And it is repeated in each ad block (2-3 times), is it possible to insert this code once before </body>?

Answer 1

If there are multiple ad units on a web page, do I need to add <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></ script> code for each of them?
This is not necessary, the adsbygoogle.js script only needs to be downloaded once.

Answer 2

you can’t
insert the code unchanged - even if it works, they can be accused of violating it, it’s terribly inconvenient when you have to fire all the resources by ID, but these are the rules
