How can I enter an Adsense within a Head? I already have the structure and the code that I am going to place, how can I implement it?
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "ca-pub-3875903759149355",
enable_page_level_ads: true
});
</script>
Your site shows many HTMLs. These can have .html files, or be generated by .php or .asp, etc.
Each HTML file (generated or not) will have this structure:
<!DOCTYPE html>
<html>
<head>
...
</head>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
You must search and paste the AdSense code within that block. If there is more than one file, you will have to do it in all that are relevant.
