I am the founder of PayPerPost.com and one of the core features is easy link building. I am sure that many of you are already using the service. What can we do to make it better for link buidling? We are working on our product roadmap and want to make it the best tool possible.
I've followed the developments of your offering closely over recent weeks and it's getting to a stage where there's a good amount of activity - enough for me to be jumping in soon as well as an advertiser. One thing us link builders (if it's for ranking instead of advertising/buzz generation) are often concerned about is Google PageRank. Maybe that could be one of the attributes, a minimum PR specified or say $5 for PR 1-3 homepage, $7 for PR3+ etc. The ability to give a choice or fixed anchor text that has to be used by the blogger is important for us as well. 'Click Here' is rather useless for us.
We have the ability to specify anchor text. That was an update about a week or so ago. We are wokring on the ability to specify pagerank and alexa rank, give us about a month or so to roll that out. That will be the Beta 3 release. Thanks for the feedback!
Perhaps you could add a 'link checker' in the advertiser report. With a simple crawler on a weekly cron it can be verified the links are still there (and without nofollow). PR of the page can also be reported. Accountability is important IMO if we want to spend a decent amount of our advertising budget on a service like yours. For long term success I'd like to see some added incentive for advertisers to use your service. Up until today I've been successful here on DP paying people to post sch blog posts, at no extra charge but what the blogger gets. DP probably has a bigger audience than you and the barrier to entry is rather low, though you have the first mover advantage. But with added features and incentive for the advertiser I can see it grow big for you. Maybe fees could drop according to spend (if not already) or 'buy 10 get one free' type deals. I'm not just being tight, I really think it would convince more people to use your service. Another point I just thought of is a discretion. We all know Google et al frown upon buying your way to the top of the SERPs. Your service facilitates just that. If we can post opportunities without our links and names being shown in public it's impossible for search engines to algorithmetically determine we're buying links. They'd have to sign up as bloggers. So if you get automated blogger log ins blocked properly and make sure we don't have to go public with details that aren't necessary to do the opportunity deal then we'd feel much more comfortable using such a mass 'link purchase' tool.
I agree about the Page Rank info/filter. I posted an opportunity for 16 bloggers. half of them had a page rank of 5, half of them were at 0. Another thing that would be nice is if you could limit the number of posts per day for an opportunity so that it doesn't all get posted in 1-2 days, hence it has more of a "natural" link development. May be being able to filter out domains is a good idea too if you don't want links coming from blogger.com or livejournal.com. (Although I don't think this can hurt you)
