A few days ago a Kikabink News subscriber contacted me to ask what kind of money can be made selling ebooks. The short answer is: anything from zero to millions of dollars.

Ebooks are actually becoming BIG business with the advent of the iPad, Kindle, Nook and other e-readers. Meanwhile, they have been the Internet marketers’ medium of choice for providing how-to information across a range of niches online.

When it comes to getting a domain name, should you register a new domain, get an expired domain, back-order a dropping domain, bid on a domain name at auction, or buy a domain name for sale or make an offer to a domain name owner?

Following on from my article explaining the differences between each of these approaches (see Should You Register a New Domain Name or Buy a Domain That’s Expired, Dropping or For Sale?) let me outline some of the pros and cons of each.

Here are the top 50 most visited web properties in the U.S. in June 2010, based on data from the comScore Media Metrix service. All figures are per thousand unique visitors:

So you’ve got an idea for an online business, want to build a website and need a domain name. Your first instinct is probably to come up with a name for your business and see if the domain name is available. Stop! Before you register that domain, consider whether you may be better off registering an expired domain name, back-ordering a ‘dropping’ domain, or purchasing a domain name for sale.

We’ll talk about the pros and cons of registering an expired domain name, back-ordering a ‘dropping’ domain or purchasing a domain name for sale in the second article in this two-part series. For now, let me explain what is meant by registering a new domain, registering an expired domain and buying a domain for sale (whether via a domain name ‘drop’, at auction, via an online marketplace or by way of private sale).

Whatever your response you get from an email campaign, you’ll likely get the biggest response within the first day of the mail-out. Experian Cheetahmail’s study of 40,000 emails sent in March 2010 shows that the greatest proportion of email opens and transactions occur within a day of recipients receiving the email.

As the results below indicate, 76 to 84 percent of all emails opened are opened within a day of being received. Once a week has passed, almost all emails that will be opened, have been opened.
