It's a tough economy and it's not just affecting the typical brick 'n mortar. At an increased rate I've been receiving notifications that some of the affiliate programs I'm using are closing or potentially running low on funds in their Network accounts. It requires careful attention so that you, the affiliate, are not the one left out to dry.
First, make sure the affiliate network you are signed up with has your correct email and check to make sure you are notified of changes. Just because a program within a network closes, doesn't mean the ads won't keep displaying, it just means you won't earn a commission.
Also, make sure that you sign into your Affiliate Network site every day. This will help keep you aware of new programs being offered, news, and potentially new tools to help you make more money. Lately, some of the news I'm getting from long term affiliates are coupon codes. These can be a great way to bring more visitors to your site, since you have something to offer them to buy from the company you are affiliating for.
Lastly, I can't stress enough, make sure you are getting updates from all of the affiliate programs you are signed up with. Often times the commissions end immediately, so the longer their ads are up on your site, the more money you will lose.
