Google Adword is best at present time, but facebook getting popularity rapidly that can be threat for google to keep their present position!
I am for google adwords, my opinion is that traffic came directly from the google search engine is "better" than the traffic came from Facebook.
We do both, although our budget for Adwords dwarfs that of Facebook. To me, they are complementary pieces. We get more sales from Adwords, but Facebook helps us spread the word about our services. We use a service called Antvisit to monitor those campaigns, plus Adcenter. It's very convenient. They offer a free trial, and since it's still in beta, you can get 90 days for free!
Google Adwords is better than facebook. Because the use of Adword is also easier than facebook. I think Adword is preferable according to use. I like Google Adword.
Google is able to directly detect users' instant needs and respond to it by displaying the appropriate ads, while Facebook uses members profile to guess their needs and show them the ads.
I would prefer adwords. Your traffic on Facebook isn't really looking AT THE MOMENT for your services. You can filter on interests and so on, but you don't know what people want to see as advertention. When you use Adwords, you KNOW EXACTLY what the person is LOOKING for. If you help them to this needs (get a convertion), you will increase sales... Just my thought, I would go for Adwords... A good Facebook search engine could be a serieus thread for Google...As said above: Facebook is indeed a company which can reach the top.
Seems that facebook would be more for branding and google more for finding clients looking for your product or service, no?
I would say jump on the facebook bandwagon while it is new and people are not used to it, but Adwords is so stable ya know. You get paid for taking the leap into new things
On facebook I have got a lot of new "FANS" on my "FANS" page.... but for business I see nothing. Google I see a bill but nothing more unless I login and see were the traffic is coming from. At least on FB i see more "FANS".... One nice thing about facebook that I love is I can pick to only have new people see the add vs. current people and I can choose more on who see's it as fare as age and so on.
