deepglce We are happy with visitors from all traffic sources (Google, Facebok, Quora, etc.), as long as it's organic. While we don't disallow paid arbitrage traffic, we also don't encourage it (hence we don't have any recommendations) - as it's very easy to be scammed in this field and have the "visitors" to your site actually just be bots, which isn't allowed by Google. For any publishers looking to go down this route, we ask that you link your Google Analytics and Google AdSense accounts to Ezoic, via the dashboard, so that we can monitor the legitimacy of this traffic.
If you mean that you are paying to promote the site via ads on social media, then that is perfectly acceptable and won't require the steps above - but, you may want to ensure that you are protecting against bot traffic on your site.
