People keep saying that the extension doesn't matter. I am here to tell you that that the extension you use absolutely does matter. Always use a .com domain when you can. I actually filter out any domain that does not have a .com, .net, or .org extension when bidding for Ads or buying text links.
A month ago I bought A .info from GoDaddy because of the sale and it is still not indexed. According to the IWeb Tool it has not been Google banned. But now I understand why it is taking so long. I just need to be a little more patient. .99 cents from GoDaddy is a hard deal to pass up.
