please advise about a simple ad tracker

hello.

I tried searching, but sorry, could not find what I am looking for.

I have placed a few simple gif ads on a few sites (paid ad) and I would like simply to automatically check everyday that the ads are there and correctly linked to my site.

I know that there are some very sofisticated ad trackers which track every click ...... but I am looking for something very simple, one that does not need a special link ..... just something that checks regularly whether my banner is still there and is linked to my site.

What would you advise me ?

Don't :flame: me please.

Thank you
