Banner Ad Design Brief
We are Gadgetshack.com, and we need a new category banner for this page on our website: http://www.gadgetshack.com/wireless-driveway-alarms/
The image we have now is great, but it's the wrong size and is due for an update. Please post a design that follows the elements already found on our website.
Specifically, Sans serif font, clean lines and edges, with a basic, soft gradient in the background. Preferably gray.
We're not looking for special effects- we need something professional, subtle, and simple. Our audience is in the senior citizen category and therefore are not impressed by fancy graphics or lens flare, etc etc.Something easy to read and understand is best.
Positioning and placement of our products is KEY to a good banner.
Target Market(s)
Adults and senior citizens (30 years old+) Homeowners, people usually unfamiliar with using or navigating websites, etc. United States.
