Seems that the crawler follows the filters, like on this page:
https://www.tuttoperlamoto.it/shop/by,product_sku/results,1-60.html?keyword=&viewmode=list&cff_3%5B0%5D=3630&cff_3%5B1%5D=3437&cff_3%5B2%5D=35584c2f36584c&cff_3%5B3%5D=5332584c&cff_3%5B4%5D=33584c2f34584c&cff_3%5B5%5D=31312e35202f203436&cff_3%5B6%5D=3034&cff_3%5B7%5D=3536&cff_3%5B8%5D=4c2d4c&cff_3%5B9%5D=3432&cff_3%5B10%5D=5853&cff_3%5B11%5D=382e35202f2034302e35

Is that yours?

Not mine but same template..

And seems you are right, its filtering.

[GJC Web Design]

yes .. the VirtualPlanet filter thing

try

Disallow: /*?cff

in your robots.txt

Thanks GJC

I had a similar problem and so I use the following in the robots.txt to eliminate all possible unwanted indexing.

Code Select Expand

Disallow: /?start=*
Disallow: /*by,product_name*
Disallow: /*by,created_on*
Disallow: /*by,product_price*
Disallow: /*dirDesc*
Disallow: /*dirAsc*
Disallow: /*results,*

Of course, by,xxxx depends on the sorting options used.
