Things you should consider when purchasing a domain name.
Each year companies spend thousands of dollars on Google AdWords to get a better search listing when a good descriptive domain name may do the same for much less money or at least significantly cut down on their advertising budget. Spending on a good domain name now can save you a lot of money on advertising in the future.

For example if you started a blog about the Christian family tree or Christian genealogy and had the domain ChristianFamilyTree.com chances are it would get a better search listing than using your own name in the domain. You could get a better search listing by having the generic descriptive words as part of the domain and save more than the cost of the domain over time by spending less on advertising. Buying a good domain name can save several thousands of dollars in just a few years.
