REL = cannonical and web app

[waynekolenchuk]

I started a web app campaign for a site that I recently finished. It had no errors or warnings, but issued rel=cannonical notices for every page on the site.

What does this mean?

Items under the "Notices" section are just that - notices.  If a canonical tag points to a URL other than the page it is on, the notice comes up.  This is because engines will not count this page as the reference resource, meaning it won't have the opportunity to rank - which could be a terrible situation if you're using the tag incorrectly.  SEOmoz includes the notice just to make sure you're targeting the right page.

Additionally, you can find information about other crawl diagnostics in the SEOmoz Help Forums.

I'm using Wordpress, which insets the rel=cannonical tag on every page, and they are pointed correctly, so I I'm OK, right?

Yessir.  SEOmoz is just trying to have your back - there's no need for concern whatsoever.
