Traffic data is very bad. Some sites that receive 500,000+ monthly traffic. Ahrefs only show 1000-2000. Do not trust the stats. Just see their negative reviews on trustpilot at 1.7/5 and that is with most of the 1 star reviews being removed! clickstream data is garbage. Also the support is terrible and arrogant replies. Expensive fake data !!
