How to properly format Clean-param in the robots.txt file?

Question

Search Engine Optimization

Hello! Please tell me, I need to set a ban on the processing of erroneous addresses (like www.sait.ru/ct-menu-item-2/t3zvtv8fmR62HAs) on the site.
As I understand it, this can be done in Joomla through Clean-param? (seems to be Clean-param: sid /index.php, but I'm not sure).
Tell me how to register and where to place it correctly? It can be shown with an example.
I am newbie.

Answer 2

Good evening.
A lot of links on the site are primarily like this:
www.sait.ru/ct-menu-item-2/5p3DuQqkzPprwCP
www.sait.u/CT-MENU-ITEM-4
www.sait.ru/ct-menu-item-4 /NvfWb5AzCVSHtyV/
After the last slash, everything is superfluous (abra kobra) The site address ends without a slash
How to issue the Clean-param directive in this case? ...(Jumla)

Answer 3

Clean-paramthis is for parameters i.e. what goes in the address after the question mark.
for example

https://www.sait.ru/?param=1 _

To prevent the address with the parameter from getting into the index, Yandex uses Clean-param.
For example
Clean-param: param /
Then the search will contain only the address without the parameter param, because most likely it still duplicates the page, and this is not good for indexing the site.
And on your question of blocking the indexing of erroneous addresses, you need to " dig " in the direction of the Disallowpattern of erroneous addresses in order to block them.
