Let's say I have an EMD site with 1000 words on it and well optimized. The competitors have the keyword in title and some have it in description but that's it. Their PR are 4, mine is 0. Is the PR important factor at all while trying to outrank them with minimum amount of backlinks. I ask this because I have a site with PR 4, it has no competition for the exact keyword and it is not ranking in the first 100 results. I also have a site with PR 0 and it is on the second spot in G in the middle of sites with PR 4. It seams to me that high PR doesn't actually have any advantages in giving the page a higher ranking. What are your thoughts?
