Unusual number of ad requests

[denisl]

Yesterday, one of my sites had about 3 times the normal number of ad request according to the AS performance reports on url channels. However when I look at the report for Custom channels, the figures are normal.
Is this a bug on Adsense side or indicative of a problem on my part?

Most times a wait and see if it repeats, and consistently, is what you want to do. One day... no worries... a week, on the other hand, night need investigation.

Do you use link units?

[denisl]

No, I don't use link units. The same thing is happening today so have sent an email to adsense support - thought I would try it for the first time.
I had been making changes to the site the day before as I get it ready to resonsive, so there are responsive ads in there. I did have a few hours where I accidentally had 4 ads on a small number of pages, but that was corrected for this effect showed up.
I ant see anything wrong with the site or the ads.

Well if you're using any custom channels, you can add a second dimension and see which channels are generating the requests.

[denisl]

The custom channel report appears normal. It is only the url channel report which is showing the unusual high number of ad requests.
I assume it is not possible to have a rogue ad that does not belong to a custom channel.
The Ad Unit report shows a normal total figure for ad requests also.
As I said earlier, click and earnings appear normal.

Then I probably wouldn't worry about it myself.
