How can I make the site I publish in the Tor browser appear on hidden wiki sites ?
There are many link aggregator sites where you can add your onion for free and it will be indexed in search engines. These aggregators are filled with scams though. If your site is useful or interesting, it will eventually be added in other lists. If your site makes money, expect many phishing copies to appear. You can also pay for ads in other sites, the price will vary according to the traffic the site receives and the service you're offering.
