Disallow: /category.php? in robots.txt

[outblast]

Its ok to use Disallow: /category.php in robots.txt so google will not index anymore the categories?

will this affect the indexation of my products?

[vekia]

it will not work as you expect, because the url (without friendly urls) to categories looks like:

index.php?id_category=4&controller=category&id_lang=1

so if you want to block categories for robots - you should block urls one by one

[FME_Modules]

No it will not and yes the you can block directory and any URL coming from that directory will be restricted for Google to crawl.

if you make seperate directory of folder for your product categary then you can disallow Google crawler by directory or folder name.

 

User-agent: *

Disallow: /folder1/

or

User-agent: *

Disallow: /dir1/

Disallow: /dir2/

Disallow: /dir3/
