Looked a site recently and realised that the link was no longer active, in fact the old aff scheme was not active.
A quick shimmy with the links and first sale £22 commison. Hardly any work.
So check your old link, there is momey in them!
Got a couple sites I found last week that had a ton of dead links. Gotta get those fixed up this week.
One of the main reasons we rolled our own system to easily change links and switch networks. We also do a daily 404 check on all our aff links.
