Do you think my site is ready for SEO now?

My site (see signature) has been online since last year August 2006. From August till the end of December it was just for fun and now I started serious to build my business step by step. It seems it works and i'm not making lots of money from it, just almost break-even. Since last month I think I am building more and more links automatically (by the file uploads and spreads through forums).

I even notice some Organic SE traffic from Google and Yahoo. It is not much but i'm happy i get some traffic from organic SE. This month January I received 346 conversions from SE Google and Yahoo spread with 150 keyword phrases (not all different keywords, some of them are just like: upload 700mb and 700mb upload), so on daily average it's 21 SE conversions.

Do you think my site is ready to pay full attention on making the site more potential for Search Engines?
And do you think I can get more visitors from Search Engines than I have now?
What should you advice me to do?
Is somebody able to help me with this?

By the way.. I did not spend time or money on Search Engines.. it just happens automatically.

Thanks in advance (big up)

 

I would work on creating more unique content before you try to "SEO" your site.

Obv. the best thing to do is "SEO" your content all at the same time

 

PS. As you can see my site is not a content site. It is a service provider for file hosting. The power of the site is to provide less content as possible to make it user friendly and make quick uploads possible. I know this is a problem because content = king, so this is also an issue

 

I personally think that there are lot proxy sites, forums, arcade, file upload, pixel websites and SEO blogs. I think they cannot have more potential in SEs. Maybe I'm wrong, but I would forget about that idea, if you don't have something especial to offer.

Your website is interesting because it goes up to 700MB, but I wonder how much storage you will need if you get 1000 uniques daily
