Opencart short seo url

i have changed in the seo_url.php the folowing line.

from:
$url .= '/' . $query->row['keyword'];

to:
$url = '/' . $query->row['keyword'];

so if i click on a link on the website i always got the main url like

my problem is, that google has still the old url (https://www.site.de/category/subcategory/product)

How can I achieve this?

Solution

You should use this https://websiteadvantage.com.au/HtAccess-301-Redirect-Generator tool to create the redirects with 301 Moved Permanently all the URL you would like to change. Then add these redirects to your's site root /.htaccess file.

Example:

RewriteEngine On  
RewriteCond %{QUERY_STRING}  ^$  
RewriteRule ^category/subcategory/product$ /product? [R=301,NE,NC,L]

Also you should submit a new sitemap.xml file to Google Search Console https://search.google.com/search-console/about.
