The unfortunate truth is that there is no magic bullet: proper attribution of dark social requires rigorous campaign tracking. The optimal approach will vary greatly based on your industry, audience, proposition, and so on. For many websites, however, a good first step is to provide convenient and properly configured sharing buttons for private platforms like email, WhatsApp, and Slack, thereby ensuring that users share URLs appended with UTM parameters (or vanity/shortened URLs which redirect to the same). This will go some way towards shining a light on part of your dark social traffic.
Hey Marcus, thank you so much. Hearing all the compliments make me wish I made a list of 100 traffic sources :) I don't think anyone would publish it though...too much work, lol. I hope everyone will use it and find some fresh traffic for their blogs, most of these sources will work for any blog but some will work better for specific niches. Thanks for sharing and appreciate the comment!
