Do some more research into the company at the end of the day if it does not work out you can always take them off, however make sure they are not asking for money to join, wish you well with it

If its a good fit for your site and the affiliates pay is good for you. Go for it. You can always not promote if it don't work for you. Just my 2 cents worth as you already have some very good answers here.

Investigate the company thoroughly. Then let it rest a while and then make a decision. Leave yourself an out in case it does not work. If there is a check in your spirit, then don't do it. Maybe you can put them off for a few days or even a while longer. I will be praying you make the right decision! Blessings,

The whole point of affiliate marketing is to be an affiliate & make money.
If they're legit & what they're selling ties in with your website, then do it. If not, then don't.

There are so many companies. Look for info about them, google. It depends what they want to promote, what kind of products do they offer to you? Nothing wrong to be affiliate. Good luck:)
