Layered Navigation block disallow

[viktor123]

Hi, 

 

I recently noticed that Google webmaster tools shows duplicate content in all pages with layered navigation results (sizes, colors, etc). Is there any chance to block these results from robots.txt or noindex them. The results use selected_filters attribute.

www.domain.com/10-somecategory?n=10&selected_filters=-xs&id_category=10&p=2

What i did on a clients site to combat that is write  little smart script that uses regex to generate a canonical url.

Ok, that sounds like a solution. I tried adding in robots.txt 

Disallow: /*controller=selected_filters

Disallow: /*controller=filters

but, that probably might not solve it. 

Any chance I take a look at your script?

 

Thanks

Sure, it is really rough looking an part of a much larger script, but this is what I have for it so far.

{assign var="can" value=$smarty.server.REQUEST_URI|regex_replace:"/&n=\d+$/":""}
{assign var="can1" value=$can|regex_replace:"/&id_category=\d+$/":""}
{assign var="can2" value=$can1|regex_replace:"/\?selected_filters=/":""}
{assign var="can3" value=$can2|regex_replace:"/\?id_category=\d+$/":""}
{assign var="can5" value=$can3|regex_replace:"/n=\d+&/":""}
<link rel="canonical" href="http://{$smarty.server.HTTP_HOST}{$can5}"/>
