'Crawler' is a generic term for any program (such as a robot or spider) that is used to automatically discover and scan websites by following links from one webpage to another. Google's main crawler is called. This table lists information about the common Google crawlers you may see in your referrer logs, and how they should be specified in, the meta tags, and the X-Robots-Tag HTTP directives.The following table shows the crawlers used by various products and services at Google:. User agent token is used in the User-agent: line in robots.txt to match a crawler type when writing crawl rules for your site. Some crawlers have more than one token, as shown in the table; you need to match only one crawler token for a rule to apply. This list is not complete, but covers most of the crawlers you might see on your website.
Full user agent string is a full description of the crawler, and appears in the request and your web logs. These values can be spoofed. If you need to verify that the visitor is Googlebot, you should. ‡ Chrome/ W.X.Y.Z in user agentsWherever you see the string Chrome/ W.X.Y.Z in the user agent strings in the table, W.X.Y.Z is actually a placeholder that represents the version of the Chrome browser used by that user agent: for example, 41.0.2272.96.

If you want all of Google to be able to crawl your pages, you don't need a robots.txt file at all. If you want to block or allow all of Google's crawlers from accessing some of your content, you can do this by specifying Googlebot as the user-agent. For example, if you want all your pages to appear in Google search, and if you want AdSense ads to appear on your pages, you don't need a robots.txt file. Similarly, if you want to block some pages from Google altogether, blocking the user-agent Googlebot will also block all Google's other user-agents.But if you want more fine-grained control, you can get more specific. For example, you might want all your pages to appear in Google Search, but you don't want images in your personal directory to be crawled. In this case, use robots.txt to disallow the user-agent Googlebot-image from crawling the files in your /personal directory (while allowing Googlebot to crawl all files), like this:User-agent: GooglebotDisallow:User-agent: Googlebot-ImageDisallow: /personalTo take another example, say that you want ads on all your pages, but you don't want those pages to appear in Google Search. Here, you'd block Googlebot, but allow Mediapartners-Google, like this:User-agent: GooglebotDisallow: /User-agent: Mediapartners-GoogleDisallow:User agents in robots meta tagsSome pages use multiple robots meta tags to specify directives for different crawlers, like this:In this case, Google will use the sum of the negative directives, and Googlebot will follow both the noindex and nofollow directives.
