How much work would it take to rank for..

"registry cleaner review"
I have a .info name I bought, and was thinking of making a review site, and doing some SEO. Though if I can't hit top 3, then I guess it's not worth it really...or at least first page.
Yea so for some of you more experienced people, how long may a keyword like this take based on competition (and the fact that I've never done any SEO lol).

Thanks

You can always learn SEO, I had never done it before, but I started reading up on it, making backlinks..... and my site comes in PR1 at position 1 for some search terms.

you haven't given enough info for some one to answer the question really.

Whats the approx searches for it a month, how many webpages are you competing with, what kinda of SEO have the people on the first page been doing for that term regarding link building, content, etc, etc.

Do a bit of research yourself, and you will be most of the way to answering the question.

My rule of thumb is, for a MICRO niche that I REALLY want is NO PR4, all PR3 and lower.

But if its lucrative ill spend the 4-6 months building backlinks naturally to get past the PR4s if its worth it. And when it comes to PR5 or higher I will not do it pretty much at all, too much time and work for something that MIGHT not work out.

Never put all your eggs in one basket.
