does having a paid back link on business.com still hold any weight ?

cheers

Good question. What's the cost these days?

$299.00 USD per year

Auch, still rather hefty.

Did a couple of quick spot checks and couldn't find any indexed backlinks from Business.com to some of the listings?

They've changed their ontology quite a bit, check the page you're on before choosing to renew (fyi, got a renewal notice and had to check if it was still worth it, fortunately for now in this particular case we are the only link that isn't no followed on said page)

Ditched it some time back. Once it worked for me, but then  did they get bought or something?  Not looked at the site for probably 3 years mind. 

Are you looking to renew or buy a new link Mick?

to renew the existing link that i have had for 3 years, its expired anyway now so i am going to leave it

I seem to remember leaving them when the links went nofollow. FWIW
