Do not rush this process and do not limit yourself to only a few Web sites. Take several weeks to make these analyses and review your notes carefully. Then, outline every concern or observations found and apply them to your own new Web pages. Be as objective as possible and avoid defensiveness. Do you see similar problems to ones encountered as you went through testing other sites? Look at the things you liked and disliked about the other pages and see how your own pages stack up. Now revise your own pages and then take a second look at them for the same five principles.
This method will not be as valid as a full-scale market research or focus group test, but it still should be of some help in trying to get as much out of a new Website in terms of user happiness and return visits.
