TechLeads scans public websites and detects Crazy Egg from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Crazy Egg's website count divided by the website counts of all Site Optimization technologies we track; a site using two Site Optimization tools counts for both.
