Having trouble with Adsense banners? I have a page with three fixed-size banners (336 x 280) and sometimes they appear blank. It's random - one might work while the others don't, or none may work at all. The code is the same for each banner:
<div id="banner_rectangle" style="width:336px;height:280px">
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- 336_280_text_images -->
<ins class="adsbygoogle"
style="display:inline-block;width:336px;height:280px"
data-ad-client="ca-pub-XXXXXXXXXXXXXXX"
data-ad-slot="XXXXXXXXXX"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></div>
The Google code already specifies the banner size, and the parent div also has the same size directive. How can this issue be resolved?
