Invisible Adsense

[pljordaan]

Hi,

When designing a website, or placing Adsense in a Blog,
I often have empty spaces where the ads suppose to be.
Most of the time the ad higher on the page is showing.

Sometimes I had moved the code a little bit up or down,
in FrontPage, without results. After some time I refreshed
my browser, FireFox, (on my still published website) a
few times, and suddenly my ad appeared, so it was not
necessary to change the page after all!

Could it be useful to insert a code to refresh the page?

I also have the same altered template (Minima from Blogger)
used for more then 10 Blogs, (only the links are different).
When I look at those Blogs, on some the ads are showing,
but not on others. Sometimes refreshing helps, but not always.

Could it be the number of ads already showing be the cause?
I have a 4 link unit at the top, 1 large rectangle at the bottom
of my Blog, this one is sometimes 3x showing, and 1 sky scraper
120x600 at the sidebar, which is seldom visible.

Thanks,

Peter Jordaan

It takes time for Google to index your site, figuring out which ads are suitable to be shown and then displays it.

It can take anything from a few hours to a week.

Check out Google's help page at https://www.google.com/support/adsense/bin/static.py?page=alternateads.html
.

In particular, read the section at the bottom "Collapsing Ad Units," which is how to get the reserved adspace to collapse if Google does not have any ads to put in there. This may happen occasionally, especially before Google fully indexes your site, but may still happen occasionally because of their ad inventory.

With multiple ad units on a page, maybe they just didn't have enough ads to fill all your spots.

I use one ad unit per page and NEVER get blank space- they always show PSAs if they have no ads. But I rarely get PSAs- almost always get relevant ads within minutes.

Regular spidering & indexing has NOTHING to do with this! Because like I said, I can put up a brand new site & see relevant ads in a few minutes. Obviously the site isn't getting spidered & indexed in minutes of me putting it online, with no links to it, even. The spider for Adsense is a different one than the usual googlebot.

It would be helpful to know what really causes this as some of us experience it and others dont.
