I am a Google Adwords professional. I led the online advertising team for a large e-tailer for more than 2 years and in that time our weekly revenue were more than 1 million pounds or about $2 million every week from Paid Search alone.
I have strong experience in understanding CTR through banners as I have managed both adwords as well as adsense. Have done extensive research on conversion through banners through experimenting with sizes, colours, placement, text, graphic, exposure time etc.
I now support more than 8 US accounts which I have been handling since 2003 through my business dotlabz. Couple of them are the largest online sellers in US.
Please let me know if you would be interested.
thanks
