One question I have is hosting. I'm wanting to buy the baby hosting package again on hostgator and get a domain from godaddy.com. Then, as I complete that site and get ready to add more, I want to add those sites onto the same hosting package, and from what I understand, those are technically listed as subdomains of that first domain that I'll purchase. So my question is, if I get a domain name related to a certain niche and then later on I begin to add other add-on domains that are in other niches, will the SE's see that those sites are subdomains of a site with a totally unrelated name and therefore discriminate against those sites?
Also, I had a question about checking my page 1 competition for keywords. I've been using yahoo site explorer to check backlinks, and pr checker to check the PR for the sites which are currently on page 1. I just got through checking for a keyword where most of the sites have little or no inlinks, and only a couple of the pages even rank at all, but they rank at 4/10. There's some relevant ads on the side, so I know the keyword is being targeted. My question is, outside of buying something like Market Samurai, is there anything else I can do to assess competition before I plunge in? I may invest in something like that soon, but I'd love to just get out there and make something work first.
And does amazon associates accept most site owners as long as they're not from one of the prohibited states? Should I go out and get the domain, hosting, and then apply for Amazon, or should I finish the site and then apply? I'd like to be a part of their program but if not, I know there's still eBay and other methods.
