Maintaining a Page Rank if you manage to get to 5+ is really not an issue, as long as you didn’t pay huge amounts of money to get you there.

Sure if you don’t want to learn, spend huge amounts of money getting links in the big directories, to me that isn’t SEO, that is buying your way in. It’s a short term fix, which you’ll be repeating a lot. The simple Techniques of learning how to write your content in a way which will be searched for, and talking about your site in your spare time “on the web” is more than sufficient and costs you nothing.

It’s perfectly feasible to get by SEO’ing as such, with little to no budget. From the ground up, the space of a few months, i’ve spent nothing, but my own spare time, and have managed to get my new company website from page rank of 0 to 3, at the next update, I expect it to be 4 or 5.

It was already doing well (top 10) in google searches, in areas I had not expected like my Facebook App reviews, and now I’m getting more of the ones I desired more, my Game news, and Mobile Game related ones.

I’m not saying if a huge Corp had a huge budget they’ll get along just the same without it, but it doesn’t need to cost huge amounts of money either, if you did it right in the first place.
