We own a Painting Contracting site, for both Residential and commercial. and now a Commercial site, marketing to business only. Is it possible to have two different adwords campaigns? Some of the keywords are the same, as the type of business is similar.
Yes, It is possible to have two different adwords campaign with same keywords However only one of your ad will be shown ad a time Google Policy: Only one ad at a time from one account Only one ad even you are advertising for same website with two different accounts.
Just make sure you don't violate the double serving policy: http://adwords.google.com/support/bin/answer.py?hl=en&answer=14179
You need a separate adwords account for each site. You cannot bid on the same keyword twice within the same account and take up 2 ad spots.
