bobbolger: How long does it usually take to get on the first page on Google for competitive keywords?

It's impossible to know and you'd need to spend quite a bit of time and money. It 100% depends on the competitiveness of the keyword.

Sam is spot on. It is literally impossible to calculate. Every keyword has different competition and then of course there is your own website which plays a big role. If the on-page SEO is up to scratch then it will take even longer.

Its really not that easy to get on google Pr1 .It takes time.It will be easy to get in to high pr if u have low keyword.But its really uneasy to bring high competitive keyword to pr 1

it depends on the website

Must have a very accessible website, back-links many, many visitors, unique content and quality, the keyword to match the website.
Without pay do not think you can go too fast on the first page in google.
Just so.

It depends on Quality of backlinks
