The conclusion I can make is that it would be not good to tell my client a number for this, so I have explained him how this works and told him I can not tell a number or even how much work it would take me to reach the pr6 goal he wants.
The other thing I would like to suggest is that (I am presuming you are an SEO) SEOs should really set targets for their clients in terms of SERP results or traffic or something else that really matters. PR is not really a feesible form of measuring results any more (Especially after the 4/4 update). Maybe you could suggest to him that you will work on his SERPs. Target 10 keywords/phrases and then split the payment into 10 parts. Set a target for each SERP and then just tell him that you expect payment as soon as each target is met. Ex: Total payment: $1500 Search term 1 - Target (top 10) - $500 (most competitive phrase) Search term 2 - Target (top 5) - $200 (less competitive phrase) Search term 3 - Target (top 3) - $100 (even less competition) Search term 4 - Target (top 3) - $100 Search term 5 - Target (top 3) - $100 Search term 6 - Target (#1) - $100 Search term 7 - Target (#1) - $100 Search term 8 - Target (#1) - $100 Search term 9 - Target (#1) - $100 Search term 10 - Target (#1) - $100 This is just an example. You could do the same for traffic or if you are extremely confident in the field, base your SEO payment on sales conversions. Ex: Draw a one year contract with your client and tell him that you want 20% of incremental profits. So, if his/her profits go up by $20,000 you get $4,000. You could ask for payments on a monthly basis for each month's increase. This way, the client knows that he/she will see results and only then you will be paid. They will also be quite comfortable sharing a portion of the profits rather than paying you upfront not knowing whether they will gain anything from your work or not. Regards, dfsweb
as has been pointed out elsewhere, their pagerank is not legitimate. they get it via a 301 cloaking trick. really, it's a rather genius marketing idea ;-) the number of times you hear nichebot mentioned on forums is astounding after that.
PR has nothing, absolutely nothing to do with the age of the links or relevancy. Only the pagerank of the page linking to you and the number of outgoing links (whether internal or external)... And yes, a page can pass up to 85% of it's pagerank... so it's possible that a high PR6 website with only very minute number of outgoing links can give you a PR6... but most likely it will require a couple PR7's or a PR8, or several hundred or thousand PR0's - PR5's.... Also, see this link: Do remember that google only shows a portion of the backlinks it knows about, so G showing a backlink count of 115 could very easily have 500 or 1,000 backlinks... Also as mentioned before that, remember that PR doesn't take into account the relevancy, age of the links, trustrank, anchor text, etc. so they really have no direct relationship to search engine rankings, although indirectly it's a good indicator and and does help some.
You also have to factor in the number of those IBLs which are internal. You'd be surprised just how many of the total links are actually just internal links. I see it all the time.
