How often do you go through your sites.....
 

to make sure your affiliate links are working correctly. i think this is one of the biggest pains and time consuming things to do.....

i know i know...outsource it.

I check my sites every day. just to see hwo everything looks and if there is something I can change

I mostly a "built and forget" type of guy. I don't re-check 95%+ of the sites I have but I do have a spreadsheet that list all of them in case I need to modify an referal url....

once a day without fail

Not very often because it would be too time consuming. I've got a system, that when implemented on all my domains, will no longer require it.

daily with out a doubt

there are scripts to do that.
they can be setup to run once a day or once a week or whatever you want.
then they email you a report with what it found.

Once you put a link up why would it stop working ?

sponsor takes down the gallery it's linked too or closes the site.

aren't there programs out there that will help you do this?

I spot check my personal stuff every so often.
