Robots Refresher: robots.txt — a flexible way to control how machines explore your website

A long-standing tool for website owners, robots.txt has been in active use for over 30 years and
is broadly supported by crawler operators (such as tools for site owners, services, and search
engines). In this edition of the robots refresher series,
we’ll take a closer look at robots.txt as a flexible way to tell robots what you want them to do
(or not do) on your website.
