How to correctly implement a redirect in .HTACCESS?

Question

Apache HTTP Server

The whole point is that competitors drive traffic from all sorts of clicker farms (paidverts.com) to the site (which is in the top in HF) (payment for going to the site, clicking on ads, etc.) in order to lower the site in the search results (deteriorate behavioral factors).
How can I implement a redirect in .HTACCESS or in php (CMS of a WordPress site) when a user goes to the site via a link from a specific domain?

Answer 1

It is necessary to google for HTTP_REFERER + php | htaccess
Example: htaccess.ru/info/referral-blocking
