If you are wondering where in the code you can add rel=”nofollow’ to the top bits (view as Grid, sort by etc) of the category and search pages in Magento you came to the right place.

To clarify these links are are

http://www.domain.com/category?mode=list

http://www.domain.com/category?mode=grid

http://www.domain.com/category?mode=grid&limit;=9&p;=2

http://www.domain.com/category?mode=grid&limit;=15

etc.

Open the following file:
/app/design/frontend/default/[*your skin name*]/template/catalog/product/list/toolbar.phtml

– replace [*your skin name*] with the skin name you setup if you use a different design than the default.

If you are using the default design, replace it with ‘default’. In this case the file is here:
/app/design/frontend/default/default/template/catalog/product/list/toolbar.phtml

Add rel=”nofollow” to line 87, 102 and 104.
