I do heavy Adwords analysis with my startup. One of the more interesting things I've come to discover though is that facebook provides much higher bang for the buck in regards to CPC and CPM (based on my limited budget, I can not saturate either FB or Google for my target keywords). However - the traffic behavior from users coming out of FB is very different than those from Google (and the Google ads network).
For my current business I found that while FB was cheaper - traffic from google was more worthwhile (measured by conversions). I think that there are certain types of businesses which would do far better on FB ad network then on Googles however, and am flighting ideas across both.
It depends what type of business you are I guess:
If you want click through -> landing -> sale pretty much then Google is going to win easy.
If you want to say build up a fan page or place people on your website without exactly directly monetizing their visit straight away then Facebook has some promise. With Facebook I just don't think that buy intent will ever be there like it is when someone is searching for a product on Google.
Wondering if adding a new feature to your product or service will really make a difference to sales? Try running Adwords traffic to a split test pitting your typical landing page against a variant that highlights the potential new feature.
I don't get it. You advertise the feature but don't actually build it? That sounds pretty annoying.
