It depends . . .
There are lots of reasons to jump on a particular opportunity, and probably an equal number which would suggest, you should keep looking.
You have to be happy doing whatever it is you're doing professionally, or your work, your employer (and their clients/customers) and yourself will inevitably suffer. Possibly all three. It seems obvious that if you're employed, you should always be looking for that next opportunity for career advancement. It doesn't necessarily come around very often, but when it does, you should be open to hearing about it and ready to pursue it (see "Are You Ready For Your Next Career Opportunity?". If you're unemployed, the thinking will necessarily and understandably be different.
If you are unemployed and have the emotional and financial wherewithal to keep looking, I would suggest that if there's any doubt about whether you're going to like the job, keep looking. Marketing and advertising opportunities are slowly increasing. If you're unemployed, you should be working every day to identify those opportunities that will excite you and reward you professionally (it's a full time job to find a full time job). You accomplish that by networking with friends and colleagues and online research (not "just" job boards!). If you're unemployed, have you given enough thought to what you actually want to be doing and who you want to be working with/for?
It's amazing to me how many people actually take the time to research whether or not they want to work for a particular employer (not as many as you'd think). Rather, (especially if unemployed) they will fire their resumes off based on a job description, without knowing anything about the employer. I realize this changes if someone is unemployed, but if the position ends up not working out, permanent damage could be done to your career path. Why would you take a job you don't like or really want? The point is you should be job searching proactively, not reactively.
You should be able to describe (at least to yourself) the sorts of positions you're looking for, and understand why they appeal to you. Similarly, you should know why something isn't right for you. The better you're able to describe that to yourself, and those who are trying to help you network and identify opportunities, the better off you're going to be.
