I'm an experienced PPC user, I write very targeted ads for each of my
keywords, so I'm not sure what has happened.

Can anyone shed some light for me?

From what you are describing it sounds like it may be a problem with
your Landing Page Quality. The quality of your landing page is a
component of your overall Quality Score, and, as you probably know,
Quality Score is what determines your minimum bids.

A sudden jump in minimum bids often indicates that your page was
recently crawled and marked for poor quality. You can read the
complete landing page and site quality guidelines at
http://adwords.google.com/support/bin/answer.py?answer=46675. In
addition, we recently started taking page load time into account when
determining quality. If your page is slow to fully load, this could
also be responsible for the bid jump.

Finally, there are several threads on Landing Page Quality on this
forum that you may want to check out :

Thank you for your reply.

It's very odd, according to my Google WMT, the last time it was
crawled was on the 5th of July, it being the 9th today.

So it does seem odd that it would just randomly spike like that.

I have great content (or so I think :) and am giving the audience
exactly what they want...no ads, no pop-ups, sectioned adgroups etc...

The only thing I can think of is that I just launched a new website
with similar layout (and some content) in the same Adwords account.

Do you think that could effect it?
