How these numbers are calculated

TechLeads scans public websites and detects Google Workspace from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Google Workspace's website count divided by the website counts of all Email technologies we track; a site using two Email tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
