I'm going to pop in here and make a comment about this type of service.
It is really valuable in terms of driving targeted traffic to your site and you may end up with relationships with those that actually contribute to the round up which is also valuable as those are usually people in your industry.
I've had this done for one of my sites last year or so by someone else and it has generated traffic to the site (you can see in analytics or statcounter), has generated email inquiries and given me well over 5K in business to boot and I still get business on a regular basis from a few who supplied the round up comments.
I've not promoted the page that I have the round up on as the site it is on gets crawled often by Google so it was not necessary but should you link to it I would expect it would do very well.
Bear in mind that some are going to want a live link from your site to theirs and I don't allow that as a rule but I do give them a mention by having their site listed without a live link. You can do that or link to them if you want but that is my preference.
As to SEO this is a solid content opportunity.
As to building relationships this is a very solid opportunity.
As to generating revenue from the traffic your site brings this is a solid opportunity.
I've not used
@Geasy for this but I know him very well and have done business with him on several levels and he even had access to my payment processors for some time so if I wanted to do this again I'd have no concern at all moving forward and paying him for the service. He is a quality guy and the work he does is quality from all the interactions I have had with him over the past few years.
I'm looking forward to seeing this do very well here in BHW.
