Adsense sometimes shows random nonsense

skyscrapers instead of banners...

[seoholic]

In the last 2 months Adsense sometimes shows skyscrapers instead of banners, border instead of no border and so on. Only single random adblocks are effected.
It's a rare phenomenon. I noticed it maybe 10 times in dec and jan and I requested 1000 pages in this time period.
I am not worried, just curious.
Any experience or advise?

I don't know about "skycrapers instead of banners" but they do like to mess around with the ads. Sometimes I don't know whether I own the site or them. It's like your boss reaching for a beer in your fridge and he looks at you like "What?". noooothing

I do find that there is a small bug in Safari - if I am experimenting with a page and add a top adblock, a lower adblock will appear in the top space on the first page load, with the wrong sizing (ie the sizing of the lower block.
No real impact, though, as its only when I change the layout.

I often find that the font style and size are often not what I had chosen.

I have seen the same in Firefox. It goes away after a refresh or two.

@piatkow

when you visit somebodyelse's website, do you refresh site in order to see Ads properly? :)

So, it is nonsense that doing f5.

Not only style and size:
I sometimes see a horizontal adlink unit in a large rectangle (well, the left half of it...)

There's been as issue reported in Firefox with some ad zones in OpenX. Not sure if it's an OpenX issue, a Firefox issue, or an AdSense issue. I see it on my site only when using Firefox after refreshing the page.

(This is normally when I'm editing the page, and make a change to fix something. When I refresh the page to show the change, the ads appear in the wrong places.)

This never happens when using IE, and I've never seen it when a page first loads, only on reloads.

@eniac
I see the problem that leadegroot describes in the same circumstances. IE when testing changes to my own site.

I think it's a Firefox issue (and might be others as well; I never used Safari till I got an iPad for Christmas) I see it on my sites in FF.

I use Firefox most of the time and sometimes see AdSense ad blocks trying to show the wrong size ad or even showing content from other iframes that I have on my pages.

Usually a refresh or two fixes the issue. This has been happening with the last few versions of FF. I haven't bothered to check to see if it happens in IE, but I don't often look at my pages with IE either.

But I can't actually say if it's a FF issue or not.

It's not a FF only issue. I use Chrome.
