What is Robots.txt? Robots.txt is a text file that contains instructions for search engine robots about which pages they can and cannot crawl. These instructions consist of "allowing" or "disallowing" some (or all) bots through. This is what a robots.txt file looks like: semrush robots.txt Robots.txt files may seem complicated at first, but the syntax (computer language) is quite simple. We will explore it further later. In this article we will talk about: Why Robots.txt files are important. How Robots.txt files work. How to create a Robots.txt file. Best practices for the Robots.txt file. Why are Robots.txt files important? A robots.txt file helps manage the activities of web crawlers , so they don't overload your website or index pages not intended for public viewing. Here are some reasons why you should use a robots.txt file: 1. Optimize the Crawl Budget The “ crawl budget ,” or crawl budget, is the number of pages Google can crawl on your site at any time.
This number can vary based on the size, health, and Venezuela Phone Number backlinks of your site. The crawl budget is important because if the number of your pages exceeds your site's crawl budget, there will be pages on your site that will not be indexed . And pages that aren't indexed don't rank. By blocking unnecessary pages with robots.txt, Googlebot (Google's crawler) can allocate more of its crawling budget to important pages on your site. 2. Block duplicate pages and non-public pages You don't need to allow search engines to crawl every page on your site because not all of them need to rank, such as staging sites, internal search results pages, duplicate pages, or login pages. WordPress, for example, automatically disables /wp-admin/ for all crawlers. These pages must exist, but they do not need to be indexed and found by search engines. A perfect case is to use robots.txt to block crawlers and bots from accessing these pages.
Hide resources In some cases you'll want Google to exclude resources like PDFs, videos, and images from search results . Maybe you want to keep these resources private or let Google focus on more important content. In this case, using robots.txt is the best way to prevent these pages from being indexed. How does a Robots.txt file work? Robots.txt files tell search engine bots which URLs they can crawl and, more importantly, which they cannot. Search engines have two main tasks: scan the web to discover content; index content so that it can be shown to users looking for information. As search engine bots crawl sites, they discover and follow links . This process takes them from site A to site B to site C through billions of links and websites. When arriving at a site, the first thing a bot does is look for a robots.txt file. If he finds it, he reads it before doing anything else. If you recall, a robots.txt file looks like this: google robots.txt The syntax is very simple. You assign rules to bots by indicating their user-agent (the search engine bot), followed by directives (the rules). You can also use the asterisk (*) character to assign directives to any user agent.
