How to prevent indexing of the old address of product categories?

Question

Search Engine Optimization

Good afternoon. There is a Renovamebel website . The search engine indexes both katalog/category and katalog/cat/category (the second one needs to be completely removed, these are the old settings). For some reason, the category is available at such and such address. How to fix it?

Answer 1

In addition to the redirect, add the following line to the robots.txt file:
Disallow: /katalog/cat/

Answer 2

Give your site developer a kick first.
Then redirect from katalog/cat/category to katalog/category.
Delivered for five minutes.
