    Robots: How to Influence Crawling and Indexing on Google | SEO COURSE 2020 【Lesson #29】

    In SEO terms, the crawling phase occurs when Googlebot accesses a page and analyzes it, while the indexing occurs when the webpage appears to be suitable for inclusion in the search engine index. Since the 1990s, webmasters around the world have used a robots.txt file in the root of their websites in order to provide any bot with some instructions on how to access their content. In this very simple text file, a Disallow directive is inserted, containing the paths of the pages or folders that the bot must not scan, in order not to overload the resources of our server. There is also a User-agent for referring to a…

    Google Open Sources Its ‘Web Crawler’ After 20 Years

    Google’s Robot Exclusion Protocol (REP), also known as robots.txt, is a standard used by many websites to tell the automated crawlers which parts of the site should be crawled or not. However, it isn’t the officially adopted standard, leading to different interpretations. In a bid to make REP an official web standard, Google has open-sourced robots.txt parser and the associated C++ library which it first created 20 years back. You can find the tool on GitHub. REP was conceived back in 1994 by a Dutch software engineer Martijn Koster, and today it is the de facto standard used by websites to instruct crawlers.

    If I don’t need to block crawlers, should I create a robots.txt file?

    Today’s question comes from Pennsylvania. Corey S. asks, is it better to have a blank robots.txt file, a robots.txt file that contains user-agent star disallow with nothing disallowed, or no robots.txt file at all? Really good question, Corey. I would say any of the first two. So not having a robots.txt file is a little bit risky. Not very risky at all, but a little bit risky. Because sometimes when you don’t have a file, your webhost will fill in the 404 page, and that could have various weird behaviors. And luckily, we are able to detect that really, really well, so even that is only a 1% risk. But…
