I have a business, it's not purely online, but its presence is mainly online.I have purchased different domain names which I liked. Is there any service that allows you to compare their effectiveness attracting customers? I want to choose the one that will be more successful in making the customer click on my ads or my website as a search result or simply evokes a better service or sounds more nicely. How can I go about this in a scientific manner, with no assumptions, without spending lots of money and time?EDIT: By spending money and time I mean the most natural solution, which would be to replicate content on each (dangerous as google will penalise their ranking) and then run identical adwords campaigns for each, and see what happens. This would be very expensive, time costly and probably terrible for SEO.

I am not sure i understand the question.  You have two different domain names but they do not currently have any traffic to them?Are you deciding which domain of the two to use and start building your site to? you can track the natural traffic to the two domains by parking both of them and tracking the traffic that goes to each domain.If the site is already built then A/B testing is the way.Its very hard to say without knowing the two domain names and exactly where you are in the site building process..
