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