I'm a little confused and need some help with web design branding... I have a goal of building 10 different minisites to sell health-related ebooks within Clickbank. Each site would consist of a traditional sales letter and the affiliate resource area. I won't add a blog. I've already purchased the domains. Each domain ends with a unique phrase... Think of it something like the 'Dummies series book' i.e. Acne "For Dummies". Basically my question is whether I should build all 10 websites with the same design elements (background colors, headers, ebook covers, font style/size) to create one consistent brand identity (like Dummies) OR should I make each site look unique? Any thoughts?
The answer is in your title- Branding. Creating one consistent brand identity will also show authority and build trust as well, not to mention making up-sells on the back-end much easier.
I would also get a single brand to cover all those eBooks. ClickBank is making a great job on upsells, and it won't be hard for you to find a good designer to get the covers made (everyone judges a book by its cover ) or you can use an online ebook covers creator like this one, in any case you'll need awesome graphics to get brand recognition on a marketplace as competitive as ClickBank is. Good luck!
