404 error selected_filters (600 of them!)

[chaoske]

Hi y'all,

 

Just saw on my google webmaster tools - page, that I have 658 404-errors. I'm a little in panic right now, especially as I have no idea how to solve this one!

 

Damn it, got so far and I keep getting a little bump on the road once in a while!

 

This is how all the 404-error links look like:

 

http:// x /webshop/11-glas?n=20&%25252525253B=&selected_filters=&p=2&id_category=11

http:// x /webshop/43-belle-beau?n=20&%2525252525252525253B=&selected_filters=&p=8&id_category=43

 

The red line in the links seems to be the ?n=20, together with &selected_filters.

 

Can anyone help me to prevent this (google detected) 404 errors from happening? (through .htaccess / robots.txt ?) Filter out those 2 words? A mistake I made?

 

Many thanks in advance!

 

Greg

You should analyze the links and check from where they are coming. It seems that user chaoske is using a filter-module and the links were indexed. Google still understand and also index JS, therefore links hidden behind a JS must be, if the module is not well coded, excluded also in the robots.txt.

 

Prestashop by default exclude on robots.txt all links which should not be indexed. If you install extra modules you should control it yourself, if they aren't creating duplicate or wrong content.

 

Please also make sure that you have the option "canonical" set to yes, for to don't have any penalties on double content.
