Webmaster Tools (now called Search Console) is a free Google service that provides webmasters with information and tools to optimize their websites for Google search. The summary describes the main sections of Search Console - Dashboard, Messages, Search Appearance, Search Traffic, Google Index, and Crawls. The Dashboard provides critical issues, errors and search analytics. Messages inform of problems. Search Appearance helps with structured data and snippets. Search Traffic analyzes traffic sources. Google Index checks indexing status. Crawls monitor for errors during Google's crawling of the site. Search Console helps webmasters understand how Google sees their site differently than Analytics which shows site traffic.
