tracking clicks to external sites help

how to count them?

[silverbytes]

I need to count how many visits my site is giving to other sites. I put html text links that point to an php redirect page.
So a page called exit.php is redirecting clicks to several urls depending o the link clicked (that provides the external url).
I saw a raw log and fine! There is the hit to my exit.php and string containing the external url too.

But now:

How can I measure that? My log analyzer doesn't help.
And counting hits to exit.php is not enough (because that collect several clicks for different sites)
I want to determine how many visits I'm sending monthly to each external site.

Is there any php script, tool or free service for that?
Thank you!

You need to record the "hit" in a database.

If a link is clicked it goes to your traking page, updates a feild (value + 1) in the DB and then redirects to the page. Then you have a a count.

Try hotscripts for click counter. You dont say what platform you have at your disposal. I tried messing around with doing it with text files, but it was easier to get a host with a db. Access works, but mysql would be better when reading and writing.

If you use a different exit page for each redirect, you can just put a counter on that page, which only clocks up if there is a place to redirect to. The advantage being that you can then let your customers log on to that page at any time to see their performance.
