100% + Clickthrough

how can this be?

[chewy]

I've got an adword that contains my trademark.

It works great. Good focused traffic that converts like crazy.

I understand I'm likely to get a high clickthrough, however I just don't understand how I could be getting 110% or 120% as reported in the Google AdWords panel.

It has now happened several days in a row.

Anyone got any experience with this oddity?

Thanks in advance.

One ad display and one click gets you 100% CTR.
One ad display and two clicks get you 200% CTR.
Five ad displays and six clicks get you 120% CTR.

etc... you get the picture :)

Does your website respond quickly? If it does not, users may click twice, or more. This can be a problem with your host, or maybe your site itself is too slow before anything happens.

One other way you can get a high clickthrough rate is when the impressions are cut-off from one day and the click happens the next day (i.e. over midnight). But this wouldn't happen day after day - it would usually average itself out to 100% or less within a few days.

Over the average, this settles out nicely.

But, moment to moment, I have now seen it as high as 200%.

Site is loading fast, but not super-fast, so this could be one of the issues.

It may have more to do with the odd dial-up customer than anything else.

I think now that this is more of a small-number anomaility than anything to worry or get excited about.

Has anyone else ever seen this?

I've seen people apparently double-clicking on an ad, which leads to two clickthrus on one impression.

Another scenario:

I have my Google preferences set to "Open search results in a new browser window."

So it's possible for a searcher to click on an ad, read what the site has to say. Click another ad, investigate that. Go back and click original ad again, etc.
