Reddit for me is the best site if you wanna haul some major organic traffic, because first of all it is a community wherein there is a large amount of users active GLOBALLY. Reddit offers a lot of topics to tackle on. So with that, i suggest you create a niche has the highest active users on Reddit (you can find those numbers on any subreddit on the far right side of your browser)
In that way, if your website is about is News there is a subreddit thats called /r/worldnews, post your back link there. Be active in commenting and try to pitch passively if its relative to your topic. You could also make your website interactive and have an option where people can comment too.
Also, if you want to step up a notch, try paying for traffic if you think your website can attract more visitors, I recommend you go for forum marketing and start using Banner ads that when clicked redirects the users to your website.
They have a lot of targeting options.
Geo targeting - meaning you can target a specific place or even the entire world
Third party data - This is for specific targeting, like if your website is about shoes, third party data helps you target a specific audience about shoes. like Moms & Nike.
Browser/Device Targeting - Yes, you can target PC/Mobile, iOS or Android, Windows or MaC.
