How many % of AdSense blocked by software

A nasty system change could do something against it

I understand people with Pop up blockers, but I find it offending when somebody blocks AdSense ads.

They do not need bandwith, they are a real improvement of the page.

So how much is lost by ad blockers in Your oppinion?

Tested somebody counter strategies?

For example

1.) strange design, if no javascript
2.) strange design, if the own javascript on the end of the page does not find the javascript variables set by the adsense code

Not enough to have Google sufficiently worried to do anything about it...yet.

I display an alternative image file with the <noscript> tag on the AdSense location if javascript has been turned off. According to my statistics this occurs in 5% of the pageviews.

I do not find this an alarming percentage, but it only counts those situations where scripting was completely turned off in the browser. It does not count the ad blockers in software like Norton and others.

Just planing the complete solution

<noscript>
<a href=my_own_psa_noscript.htm>
<img src=my_own_psa_noscript.jpg></a>
</noscript>

Google AdSense code

with psa target my_own_psa

<script>
if (!google_ad_height )
{
document.write ( "<a href=my_own_psa_blocked.htm>
<img src=my_own_psa_blocked.jpg></a>" );
}
</script>

So I would have statistics

PSA from Google shown
Javascript turned off
AdBlocker has blocked AdSense
