Facebook Timeline Launches For Business Pages.
The visual billboard at the top (852 pixels x 315 pixels) can be used to convey a lot of information about a business. There's no doubt that in the coming months you will see businesses becoming extremely creative with their designs. It's extremely easy to change this cover photo so it might be worth creating multiple version of your cover photo and changing it regularly.
It's also worth thinking historically; you might want to create dates and memories from the start of your business. You can now post pictures from the entire start…effectively being an online scrap book. A great example of a full profile is Nicolas Sarkozy, his profile dates back to the 1970's, even before the internet was created!
Be creative with your profile…the possibilities are endless.
