Welcome to WebmasterWorld Guest from 220.127.116.11
Since then, it has been very hard to get the position they once had. I have had to raise bids by over 25%; still with no luck. These words had historically achieved premium listings at much lower rates. Many times the competition above me are using copy that I know from experience is not effective. These ads seem to have come from nowhere
I have and intuition that there is something "goofy" going on. Anyone with any explanation or similar experiecne.
I was assured by the adwords team that all the history from these words would follow to the new group.
If I may be bold to say: this an incorrect statement.
Starting a new ad group with kw's that are running in another ad group (regardless whether active currently or not) will take on their own quality score/history etc. Basically you are now starting from zero in this newly created ad group and trying to establish enough data/history to qualify for decent cpc's based on your ctr and other metrics that the quality score algorithm is factoring in to reach YOUR minimum cpc for this particular ad. Sounds like you figured this much out.
Now for revisiting the old ad group with the same kw's and not being able to resume things as they were....I think it must have something to do with the pause. I too have experienced this after stopping something for a while so when restarting I just have to keep at it.

If you were looking to isolate a couple good keywords in their own adgroup, then move the crappy performers out and make a new adgroup for them. Then write new ads for the remaining good performers, (never edit all your ads at once though, only edit one at a time or you will be sorry).
However I have a similar story moving the same keywords to a different site.
I have 2 sites I manage in the same market. I use the same keywords on both. One site is a deep content site like Google has advised me to create. The other one is lightweight and intended for folks that like less clutter. The kind Google says they dislike.
The deep content site has been around for 10 years and advertised on Google on and off for many years. The other site is less than a year old. The have about the same keyword count.
I use a slightly different ad for each site.
The twist is the new site has mostly "Great" keywords and the legacy site has "Poor" keywords.
I give up. I am tired of chasing Google. I have better things to do.
There are two types of campaigns in Adwords, either paying per click or per time the ad appears.
Using pay per click, Google needs some data (history) about each of your ads to figure out which would be the hypothetical cost per impression of your pay per click ad (i.e., once the ad has been published 1.000 times, and knowing how many times you actually paid for it -there was a click- it can calculate the average cost per 1.000 impressions).
Google knows that if it prints a pay-per-impression ad in a web, they will get money for sure. If it prints a pay-per-click ad... who knows?
So I have the theory that every time you have a new ad (or edit it), it needs quite a long time before it can directly compete with pay-per-impression ads. So you only have to wait.
My experience says: if you want to modify anything, the best way is not touching it but creating the modified thing WITHOUT deleting the old one. Leave it there for some days and when it starts to perform better than the old one, it's time to delete it.
Sorry if I'm stating something very obvious, but I felt very smart when I convinced myself that this was the answer to this problem (:-)=
