What are the relative values of different PageRanks?

[reddogmusic]

I'm planning a link-building campaign, and I've realised it'd be good to know the relative values of different PageRanks.

e.g. does a PageRank 5 site have 10 times as much effect as a PageRank 4 site? Or 100 times? Or 2 times?

I'm thinking, rather than spending ages getting 10,000 PageRank 3 links, I should just spend a bit less time trying to get a few PageRank 7+ links!

I'm even considering offering incentives to staff for getting links - to do so it would be good to be able to value each PageRank accordingly.

Any suggestions / knowledge / experience / stats gratefully received!

Thanks Cyrus - very helpful. I still get the feeling that getting a link from a PageRank e.g. 7 site (however relevant it is) is going to be a lot more valuable than a load of PageRank 3 sites, though maybe not as valuable as an extremely relevant PageRank 6 site...

Hi Alex,

To answer your question directly, Google's PageRank algorithm raises at an logarithmic scale thought to be somewhere between 4 and 7. Which if my non-mathematical brain understands correctly, ad PageRank of 4 is approximately 4-7 times more powerful than a PR3, which is 4-7 times more powerful than a PR2, etc.

Interesting Fact: MozRank uses a similar logarithmic scale.

But SEO5 has a very valid point. In the old days, it was enough to go after links on high PageRank pages. Today, it plays a much smaller role of importance, and sometimes doesn't matter at all.

Instead of PageRank, a few of the top things you want to look for in a potential link aquisition are:

• The Authority of the Website/Page (Domain/Page Authority)
• The Trustworthiness of the Website/Page (Trust Authority)
• Any penalties? Is it in a good neighborhood?
• The content and theme of the linking Website/Page
• Anchor Text
• Potential Position of the link
• Text surrounding link
• Other links on the page
• Title tag of the page
• Does it rank for the keyword you want to rank for?

There are several other factors, but these cover several of the major ones.

Hope this helps! Best of luck with your SEO.

For your last point, I think you meant that Google has reduced the frequency of updating the toolbar page rank that is visible to the user, rather than the true PR they use internally? If they've reduced the internal calculation, I'd be interested in reading more about that.

Hi Alex, i would suggest you to consider the following:

• Relevancy of the links as opposed to their page rank related to your subject matter
• The # of outbound links on the page where you are getting these links from. The lesser the # of outbound links on that page , the better that link is
• Competition for the keywords. What is the link profile for the sites that are ranking high for the keyword you are trying to optimize your site for
• Google has reduced the frequency of updating the true page rank of sites so using that as a factor to choose your backlinks would not be a good idea.
