Hi

What would be best way to add metatag "noindex" to my admin backend area?

Thanks,

An alternative solution could be to create a robots.txt to exclude the page.

This is not a good choice since anyone can read robots.txt and see what you dont wish to have indexed. Idea is that I dont want people to find admin login page, not only that admin login page is not displayed in search results.

I managed to set up X-Robots-Tag header in nginx config. I think it will suffice. However I would still love to see what the best way to modify backend code is.

location ~* \.php$ {
                try_files $uri =404;
                fastcgi_intercept_errors on;
                fastcgi_pass unix:/run/php/php-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;

                #prevent robots to index backend 
                if ($request_uri ~* admin(.*)) {
                        add_header  X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";
                }
        }
