Instance IDs on "Events" in wordpress causing duplicate content

[wellsgp]

Hi all

I use Yoast SEO on wordpress which does a pretty good job of insertint rel=canonical in to the header of the pages where approproate, including on my event pages.

However my crawl diagnostics have highlighted these event pages as duplicate content and titles because of the instance id parameter being added to the URL. When I look at the pages head I see that rel=canonical is as it should be.

Please see here for an example:

My question is how come SEOMoz is highlighting these pages as duplicate content and what can I do to remedy this.

Is it because ?instance_id= is part of the string on the canonical link? How do I remove this?

My client uses the following plugins "All-in-One Event Calendar by Timely" and
Google Calendar Events

Many thanks!

No problem George - I thought it would as I know a few people have had this concern, as you can see from the link.

Thank you Matt!

That is a great help and seems to clear up the confusion.

Hi

I wouldn't worry about this being an issue as the SEOMoz crawl doesn't currently take into account rel=canonical tags and will still report duplicate content and titles. This is something they are looking at adding - here is some more information from the SEOMoz staff for peace of mind -
