"Real human website traffic" is the most common promise in this market, and the hardest one to verify. Wikipedia's article on
internet bots notes that more than half of all web traffic is generated by bots, so a seller's claim alone tells you very little. Two campaigns can both show 5 000 visits and still look completely different in your reports.
The reliable test happens in your own analytics. Four reports show the most: engagement time per session, the country and device split, pages per session and the hours when visits arrive. When you compare them with the campaign report for the same dates, gaps become visible quickly.
The VisitorBoost free trial sends 2 000 visits to your site, so you can run this check on your own data before you pay. You judge the traffic by what your reports show, not by a label on a sales page.
