Well, all the CPM ads went away after adding the ignore tags(I think they were CPMs-large text that covered the whole ad unit) and my earnings went down.
So, I removed the ignore tags and earnings are back to normal, even up a little. CPMs with a broad site match are back too.
It's been two weeks and MediaPartners has spidered the page, so I'm not sure what the issue is.
I do see a few issues though:
- If there is not enough "content" inventory for adsense for a particular page or subject, I doubt the controls would have an impact.
- If the page using the controls does not use large enough blocks of text within the control (especially the include control), the controls may not have an impact.
- Since the controls can't be used around the <head></head> area of the page, it could be that the <head> area carries so much weight that the controls can't override it much.
Any other thoughts?
No, I haven't tried the opposite hunderdown, that's another idea. I'm sort of afraid to try it after my last failed experiment, but it does make sense that it could be a better way to do it.
My CTR also went down during my experiment. Then came right back afterwards(within about 24 hours). They say to allow up to 2 weeks for any effects to take place, but the site I am referencing is popular(high rankings and many inbounds) and gets crawled daily by Google.
I am hoping to hear from other webmasters who have experimented with this new feature.
I have used the ignore code on my menus and the other code on my content. And all the pages have lots of wordage. Why they can't get it right, I haven't a clue.
But it definitely affects earnings. In fact, targeting seems to be the biggest determinant regarding whether or not earnings are up or down on a given day.
The ads looked much more targeted to me when I added ignore tags. They were right on target for each page, but less money. Now that the CPMs are back, the ads are less targeted to the page(but targeted to the overall site) and more money...
I think hunderdown summarized what I also had been theorizing. I know the feature is new, but I'd love to hear about even more experiences with it, in this thread or another.
A good example of when to use the ignore tag is if you add the following to your site:
<!-- google_ad_section_start(weight=ignore) -->
"Please help aid the victims of hurricane Katrina by making a donation to the Red Cross"
Using the ignore tags in this case will help prevent your site from getting ads about hurricane Katrina.
