You can find info in how to create a cool Facebook landing page here - but I figured I'd also add some additional tweaks to really make your Facebook fan page über-special.
Shorten your Facebook URL
If you have more than 25 fans, you can change your Facebook URL to something nice - like my www.facebook.com/11m2.de - pretty, ain't it? Instructions on how to do that are here. If you need more fans, head on over to Etsy's promo forums to connect with some other Etsians in the same boat.
Connect your blog
I have an additional tab that automatically updates my blog posts. Plus, it gets me a special URL for each post that adds social media like and share tools to the top navigation. Head on over to Networked Blogs to set this up - it is really easy.
Tweak your profile picture
The profile Picture can be 200 wide and 600 high - and using that space effectively can make a huge difference. I have actually altered it so that it blends in with Facebook's top navigation.
Go to your fan page and click on "Change Picture" that appears when you place your mouse on top of your current profile picture; upload the new one.
Now your thumbnail next to posts will probably look wonky. Just click on "Change Picture" again and select "Edit Thumbnail" from the list - your can now move the cropping area till you find something you like.
If you upload more than one version to get it just right, the way I did, don't forget to delete the unnecessary images from your Photos -> Profile pictures.
