Anchor text and Google position questions

Hi,

I have a key phrase that I would like to use for anchor texts, totally relevant to my site's content.

Global search: 33100
Global exact search: 5400

This key phrase's competition is "Low" and my website's PR is 2 at the moment. Can I predict somehow, how much anchor texted links(from PR 0,1,2,3,4 sites) do I need to get in the first 5 results on Google? What else do I need to do to be the 3rd, 2nd or 1st with that key phrase? Only do-follow links can help the position? Bookmarking? Blog commenting? Anything else?

Thank you very much!

i don't think there's a way to predict how much links you need to get to Xth position..

Simply start linkbuilding the smart way - hihg pr / bookmarks / do follow / authority .. to main site and rest to 2nd tiers..

The competition "low" status is mainly for adwords to give you an idea of how many other people are paying to target them,
you're just best building the content and building three tiers of links to get you moving up,
good luck!

Internet World would have been so easy if there existed a way to calculate that...No body in this world have this calculation ..Not even Mutt Cutts

Only have about 5% density using your main keyword for your anchor text. Lots of anchor text variation is the key.

1) As elmoisred wrote, "low" in competition means that they are not many advertisers for this. Meaning The pay out for the clicks could be low and not many.
2) As you might know quality of content, website usage, serp ctr, and other factors are consider now days for a good ranking.
3) You need link diversification. You need to have click here, website here, and other stuff that will make your link build look natural.
4) Have an exit on your site. I see so many people failing this, they bring all the links in but is a dead end for the crawlers. You need to link in, and link out.

Good luck.

Thanks for your feedbacks.
"2) As you might know quality of content, website usage, serp ctr, and other factors are consider now days for a good ranking."
I have started the optimization like elimininating duplicated content, getting do-follow links, anchor texted links, bookmarking and blogging etc. etc. I hope it will work.
If you have any other suggestion, please write it.

About the anchor text. Be mindful to also add plain URL links mixed in there too. If Google only sees anchor text, anchor text it will not look natural.
