I need your opinion. You have the option to buy a homepage PR 7 link what would you prefer. $12,5/month – 40 external links max $25/ month – 20 external links max $50/ month – 10 external links max $100/month - 5 external links max
The more outbound links, the more probability to be with off-toffic links. So I think is better to be with less outbound link (if your budget if good enough).
$50 with 10 links would be the one I choose if I want the real power of the PR7 link as a main quality link if i want to add one more link i would go $25 with 20
I know $100/month with 5 ext links max is a little bite hard to swallow, on my view, gives the best value to buyers and the site. Links will be much related to the site and less PR drain from the site internal pages. $50/ month is also a good option anything above 10 links is not great value on my view.
I would go with $50 a month with 10 outbounds. I agree with some of the others that the lesser the outbound links the more powerful the link will be, I would perfer if the link was related but that is not really a big deal when it comes to passing pr. I think that 20 outbound links is the max that should be placed on a page, for a directory 10 of those should go towards the listings and the other could be spread out between featured listings and other forms of advertisting.
