Adsense, Ad Units, Channels and Losing Money

[jensrsa]

In another post I figured out that I will probably double my Adsense income over the next week or so, merely fixing up a problem that occurred since Adsense implimented the ad units.

(how much I lost, through my own laziness, over the last few months I don't even want to think about )

The problem, which some of you may also not be aware of, has two sides:

1. With the change to Ad Units all the code does not show up in the code you publish to your web site, some are embedded in the javascript portion and resides on te adsense servers.

This means that using the same channel number for different size ads may very well cost you as the ad size on your site and that embedded in the javascript do not correspond.

2. If you use a CMS like Joomla or Wordpress, you probably use some plugin to populate your Adsense. This often means that you insert the Adsense code in pieces - id, channel, size etc.

I found that the plugin I used didn't pass the info on correctly so impressions and clicks were lost - to the tune of thousands.

While this may not be a problem in your case I suggest that you check to make sure that you are getting credit for all your impressions and click throughs. One of my sites went from 85 impressions in a month to 84 impressions in the last 24 hours since I created different ad units for each ad size and made sure that the full ad code is published to the site, rather than use a plugin that generate the code.

And with luck, once I fixed the 50 or so sites involved, my adsense income will show a substantial improvement.
