How is it working for ya? Feel free to share tip ;-) One question in particular I'd love to hear your thoughts about - What's better: using a custom landing page, or using a facebook fan page as the landing page for the ad?
Custom landing page, highly targeted to users based on location and age, gender etc. That's where the real power in FB ads lie, you can target specific groups of people much more directly. I have worked on projects for local restaurants and it is effective to get down past the city level.
Yes, we've been using Facebook PPC ads since the platform launched. It's a lot more crowded there than it used to be but it's still a great place to get your traffic from if you can get the hang of it. Like the dude above mentioned, you can get extremely targeted traffic from FB, whether you're looking for location based traffic for local/offline work or generic age/gender based groups for CPA/affiliate marketing. I have to say this though... Seriously, would you really consider using a Fan Page as your landing page? Really? It's a terrible idea unless you're looking to build a presence on Facebook. Use a traditional landing page that you have complete control over of course! I'm not sure what you're marketing as you don't say, but I'll assume it's CPA offers... You should know that any opportunity you give users to click on something other than what you want them to will lower conversion rates! There are too many clickable elements that are out of your control on FB Fan Pages, making them a terrible choice for marketing CPA offers. The only time you should ever advertise a Fan Page is when you are looking for Fans. If you are trying to create some viral effect and that's why you were considering this, then hit me up with a PM, we can make you a viral landing page that won't affect your conversion rate in a negative way Peace.
It really depends on what your goals are, if your goals are to build a social networking group, that's more of a long sales cycle strategy. Similar to an opt-in email list, you will always have access to these "fans" and can promote your brand through being "social". If your strategy is more to drive traffic to a sales page and you're looking to do some simple math and try to convert targeted traffic into customers than a custom landing page will work best.
fan pages and groups are fine as landing pages, you just need to make sure you're using them correctly, as in putting the ads in the right place and give incentive's to your members to act
