I've just realised today that the HopAd Builder is being terminated, that's sad news since it was my only way to make a semi-contextual widget in order to sell clickbank products depending on my content pages's topics..
Here's the text on the HopAd Builder page:
HopAd functionality is being retired beginning July 23, 2012. Existing HopAds will continue to function temporarily, but no new HopAds may be created.
Thank you for participating in this beta feature. We will provide a date for final decommissioning of HopAds soon. Please remove existing HopAd Builder blocks from your website as soon as possible.
What's the alternative? Do they have an API and a sample PHP script we can use?
How are YOU going to replace that functionnality if you are using it?
What are your strategies / systems in order to try to come close to a contextual clickbank products display?
EDIT on 2nd september: after learning of the 4th september date for disabling of HopAd Builder, I've decided to try cbproads and so I bought directly the lifetime membership, because I wasn't going to use something which share the revenue 50/50 when I can get 100% for a small fee that will be paid by just a couple of clickbank sales! Moreover, I believe the webmaster will not give up on this product, especially since HopAd Builder is being terminated for good. And as I loggued in for the first time, exploring the options (all I want to use for now is their contextual ad widget) I've emailed the webmaster to say hello and tell him to update his news section since the last post dates from April 2012, and he replied in a matter of minutes and told me he's releasing a new, improved version of the site in a couple of weeks. Honestly I can't believe he hasn't talked about the termination of HopAd Builder yet nor about this new version of the site in his latest news block! I'm sure he will get a lot of new members VERY soon since clickbank has started sending emails about the termination of HopAd Builder just yesterday to clickbank affiliates who they know have been using their widget. Before that, the information was hidden in the page of the hopad builder, but any link to it has been removed from clickbank interface. So really, people will only start to look for an alternative, and from my first impression, cbproads is the best solution, and there's more to it than just the widget in fact! I'm going to do a proper review of it, since I want to make more and more sales in clickbank and this product I bought it so I will be able to talk about it in details.
