Basically you have four choices.
1. You have a pulley that is out of line.
2. You have the belt adjusted too tight or too loose.
3. You have the belt improperly routed.
4. You have a damaged/inop belt tensioner.
That's about as specific as I can be. Some engines have an auto tensioner some don't. I don't know what engine you have because you chose not to share that small but vital piece of information and my crystal ball is on loan to the phsycic down the road. I guess that means that any further help is entirely dependent upon you.
