Domain name buying, selling, and brokering is big business. People will scoop up the good-ones and hold them ransom or auction ‘em off to the highest bidder. Your whole business model may be cut down when you are forced to buy i-wanted-this-in-a-dot-com-but-they-only-had.org. But how much will it effect business?
Well, luckily, from an SEO perspective there is no difference. All domain extensions are created equal. The same onsite and offsite factors integral to good rankings apply across the board. I have not, however, seen any research pertaining to the user’s propensity to click a search result ending in a .org or .com. It is very possible that a shopper who is searching for shoes may not be as likely to click a .org link, because of the lingering notion that .org is for an organization
There are also branding aspects of a .org, .com, .net, etc. The general user is more familiar with a .com and may be more likely to try a .com version of a partially remembered URL; it is an easier recall. So when business branding and performing offline promotions, a .com is usually (obviously) the best solution.
But if the site is to be an SEO phenom, take your pick, all domain extensions have the ability to rank well.
