SEO Friendly?

Although my site is under construction, I like to get organic SEO going early. Webmaster Tools is reporting “Not Found” for 134 links. They mostly have a very long URL starting with /click.php?

I’m trying to find the cause.. is it this plugin? – not a problem if it is.. it’s a great plugin and I will continue to leave it on even if it is the cause. I would just prefer to know.

Here’s an example of the full URL:

It *can* use a 301 redirect. It will redirect to any URL you choose, and can act as a catch-all for any URL on the domain. It will even redirect 404s for you ??
