I have google ads placed in my website and i want to show a small indicator at left side of the page.

If google ads is showning/filled. the indicator circle will be green If google ads is not showing/unfilled. the indicator circle will be read.

Google ads guide URL : https://support.google.com/adsense/answer/10762946?hl=en

To get the data we can use like ins.adsbygoogle[data-ad-status="unfilled"] for not showing and ins.adsbygoogle[data-ad-status="unfilled"] for showing.

<script>
if (ins.adsbygoogle[data-ad-status="unfilled"] == unfilled) {
  display = "green";
} else if (ins.adsbygoogle[data-ad-status="filled"] == filled) {
  display = "red";
} else {

exit;
}
</script>

And this how, i will get to know if google ads is showing or not showing.
