How to solve issues regarding canonicalization?

[CommercePundit]

Today, I was searching for article which may help me in issues regarding canonicalization and found very interesting article on SEOmoz.

I am facing issues regarding de-indexing of pages and down of organic search engine visits.

I have done proper R & D and apply it very carefully. But, still my indexed pages and visits are going down.

I have applied canonical tag to following pages.

Narrow by search:

http://www.vistastores.com/outdoor-umbrellas?manufacturer=California+Umbrella

Sorting:

http://www.vistastores.com/outdoor-umbrellas?dir=desc&order=position

Pagination:

http://www.vistastores.com/outdoor-umbrellas?p=2

How can I improve my performance?

Using canonical tags will reduse the pages indexed, as you are tell them to index the canonical and not the copies.

visist may be short term or because of some other reason

Hey,

I agree with Alan - you've set it up correctly from what I looked at.

What else have you done recently to the site? It might just be a natural dip in traffic (have you compared YoY to see if you always get a dip at the same time) or have you done anything to the site?

What do you mean by visits dropping also? Are you talking about a few percent here or 50% drop?

You will naturally get less pages indexed with the canonicals in place - that's the idea.

Good to know that, Visits may be short term. I have set Canonical for all dynamic pages. I have done big R & D before make it happen. That study includes big eCommerce websites. But, I am surviving with my visits since January 8, 2012.
