Changes to conversion rate

google changes conversion rate

Wonder if you can help me.....

I manage the google CPC spend for our website and manage the stats carefully. We've always had a cost per conversion of around 11.5%. However, for the whole of Jan it dropped to under 10%, starting on 01/01. Then, it's back to over 11% from 01/02. Our average conversion rates are as follows:

Dec 11.93%
Jan 9.92%
Feb 11.67

Other than Jan it's quite steady. We've changed nothing at our end, and Google admin deny changing anything. But given the above I frankly don't believe that. Does anyone know what might have happened that could have caused this change?

At the moment I've got to explain to the board that "something" changed "somewhere" and it sent our cost per conversion right up but can't say what or why. You can guess how that goes down....

Welcome to Webmasterworld tcm192! :)

Probably just some more casual clickers in January.

It could be any number of reasons though. Did you change anything on the site? etc.

Nothing at all changed at our end. Besides everything else, we just weren't here on 01/01 to change anything and the variation in figures is such that you can pin the key dates to 01/01 and 01/02; far too precise to be market shifts I think.

could be toooo many reasons. It depends what your campaign is on. If it were something related to that time of year... then that's most definitely it.
Mortgage refinancing, shopping, as well as others have related effects do to the start of the year.
a lot of people make new years resolutions that could effect your campaigns as well.
