To answer some of them, here<br \/>\n  are a few facts about Google&#8217;s crawlers and how they help us organize the world&#8217;s information,<br \/>\n  connecting people to content from across the web.\n<\/p>\n<h2 class=\"numbered\" id=\"what-is-crawling-in-short,-crawling-is-how-google-sees-the-web\" data-text='What is crawling? In short, crawling is how Google \"sees\" the web' tabindex=\"-1\">What is crawling? In short, crawling is how Google &#8220;sees&#8221; the web<\/h2>\n<p>\n  Crawling is the process of using automated software to discover new web pages and to understand<br \/>\n  them. That way, when you come to Google to find a web page, we know that it exists and we can<br \/>\n  include it in your search results. All search engines rely on crawling to know what pages and<br \/>\n  information may be out there. You can watch our video on <a href=\"https:\/\/www.youtube.com\/watch?v=JuK7NnfyEuc&#038;t=49s\" class=\"external-link\">how Google Search crawls pages<\/a><br \/>\n  to learn more.\n<\/p>\n<h2 class=\"numbered\" id=\"we-have-many-crawlers;-they-each-have-important-jobs\" tabindex=\"-1\">We have many crawlers; they each have important jobs<\/h2>\n<p>\n  Googlebot is our most well-known crawler, and it&#8217;s used to keep results in Google Search fresh<br \/>\n  and up-to-date. We also have crawlers that are specific to our other surfaces, such as Google<br \/>\n  Images and Google Shopping. We provide <a href=\"https:\/\/developers.google.com\/crawling\">full documentation<\/a><br \/>\n  of our most commonly used crawlers and what they&#8217;re for. Our crawlers use easily identifiable<br \/>\n  user-agent names and known internet addresses. This way, site owners can be confident that the<br \/>\n  Google crawlers they&#8217;re seeing are legitimate.\n<\/p>\n<h2 class=\"numbered\" id=\"we-perform-repeat-crawls-to-find-the-latest-updates-and-to-provide-the-freshest-search-results\" tabindex=\"-1\">We perform repeat crawls to find the latest updates and to provide the freshest search results<\/h2>\n<p>\n  To catch breaking news articles, we may recrawl news homepages every few minutes. In other cases<br \/>\n  we might have seen that nothing has changed for years, so we might wait a month to recrawl. Site<br \/>\n  owners can influence how often recrawling happens using <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/build-submit-sitemap\/\" class=\"external-link\">sitemap<\/a><br \/>\n  files that tell us about new and updated pages.\n<\/p>\n<h2 class=\"numbered\" id=\"frequent-crawling-is-a-good-sign\" tabindex=\"-1\">Frequent crawling is a good sign!<\/h2>\n<p>If we&#8217;re crawling your site a lot, it&#8217;s an indication your pages have fresh or highly relevant<br \/>\n  content that people want to find, and that our systems are recognizing that demand. Online<br \/>\n  shopping is a great example: we crawl ecommerce sites often so that our results will display<br \/>\n  retailers&#8217; most up-to-date prices, promotions, and inventory status.\n<\/p>\n<h2 class=\"numbered\" id=\"googles-crawling-has-grown-over-time-as-pages-have-become-more-complex\" tabindex=\"-1\">Google&#8217;s crawling has grown over time as pages have become more complex<\/h2>\n<p>\n  Another reason we recrawl frequently is to fully understand the richness of a web page and what<br \/>\n  it offers. Our crawlers use a technique called rendering, which loads a site in full to &#8220;see&#8221; a<br \/>\n  page just as a real person would. Over the years, web pages have gotten more sophisticated; the<br \/>\n  <a href=\"https:\/\/almanac.httparchive.org\/en\/2024\/page-weight#requests-volume\" class=\"external-link\">median mobile page<\/a><br \/>\n  has grown in size from 816 kilobytes to <a href=\"https:\/\/almanac.httparchive.org\/en\/2024\/page-weight#request-bytes\" class=\"external-link\">2.3 megabytes<\/a>,<br \/>\n  and now has <a href=\"https:\/\/almanac.httparchive.org\/en\/2024\/page-weight#requests-volume\" class=\"external-link\">more than 60 different files<\/a><br \/>\n  to load, from images to interactive components. So to get a representative snapshot of a web page<br \/>\n  in all its glory, we might need to crawl the same page several times &mdash; or more, as new<br \/>\n  elements get added all the time.\n<\/p>\n<h2 class=\"numbered\" id=\"we-optimize-crawling-automatically\" tabindex=\"-1\">We optimize crawling automatically<\/h2>\n<p>\n  Our crawlers are engineered for efficiency, and they adjust themselves to minimize the impact on<br \/>\n  site owners. For example, when a site slows down or returns errors, our<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/crawl-budget\/\" class=\"external-link\">crawl rate changes automatically<\/a><br \/>\n  to avoid overloading the site&#8217;s servers. We try to limit wasteful crawling by caching the crawled<br \/>\n  content. And as our crawlers discover more of a website, they&#8217;re also able to recognize sections<br \/>\n  that can be covered with less crawling; for example, calendars that go to the year 9999 probably<br \/>\n  don&#8217;t need to be crawled in their entirety. Site owners can <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/robots-txt-intro\/\" class=\"external-link\">help by identifying<\/a><br \/>\n  what content doesn&#8217;t need to be crawled, which saves websites money by lowering their<br \/>\n  infrastructure costs and makes the internet more efficient as a whole.\n<\/p>\n<h2 class=\"numbered\" id=\"google-crawlers-never-go-into-paywall-or-subscription-content-without-permission\" tabindex=\"-1\">Google crawlers never go into paywall or subscription content without permission<\/h2>\n<p>\n  By default, if a page isn&#8217;t accessible on the open web &mdash; for example, if the content is<br \/>\n  behind a login page &mdash; our crawlers can&#8217;t access it, either. We have specific<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/flexible-sampling-general-guidance\/\" class=\"external-link\">guidance for site owners<\/a> if they want to<br \/>\n  give Google explicit permission to access subscription pages (for example, so that Google can refer<br \/>\n  users to that content). If you choose to provide subscription access to our crawlers, you can<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/flexible-sampling-general-guidance\/#how-to-indicate-paywalled-content\" class=\"external-link\">use structured data<\/a><br \/>\n  to continue showing human visitors a login screen without triggering our<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/spam-policies\/\" class=\"external-link\">rules on spam<\/a>. And you can keep subscription<br \/>\n  content from appearing in page previews by taking advantage of<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/snippets\/#nosnippet\" class=\"external-link\">preview controls<\/a>.\n<\/p>\n<h2 class=\"numbered\" id=\"site-owners-have-control-over-what-gets-crawled,-and-how\" tabindex=\"-1\">Site owners have control over what gets crawled, and how<\/h2>\n<p>We honor open web standards such as <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/robots-txt-intro\/\" class=\"external-link\">robots.txt<\/a>,<br \/>\n  a simple text file that lets site owners declare how crawlers like ours should interact with their<br \/>\n  pages. Robots.txt, along with <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/robots-meta-tag\/\" class=\"external-link\">robots meta tags<\/a>,<br \/>\n  empowers websites to easily communicate to Google and other services how to access their content.<br \/>\n  They can block pages from appearing in Search. They can tell us about new content they want<br \/>\n  crawled using <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/build-submit-sitemap\/\" class=\"external-link\">sitemaps<\/a>. And<br \/>\n  they can manage how frequently we crawl their sites via their<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/optimize-your-crawl-budget\/\">crawl budget<\/a>.\n<\/p>\n<h2 class=\"numbered\" id=\"our-standard-crawlers-always-respect-websites-choices-about-how-their-content-is-accessed-and-used\" tabindex=\"-1\">Our <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/list-of-googles-common-crawlers\/\">standard crawlers<\/a><br \/>\n  always respect websites&#8217; choices about how their content is accessed and used<\/h2>\n<p>After a crawl, we may use the crawled data multiple times to reduce the need for wasteful repeat<br \/>\n  requests on sites. Even when we reuse this data, we continue to respect the choices sites make<br \/>\n  through robots.txt and the controls we offer through that open web protocol. For example, sites<br \/>\n  can use <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/list-of-googles-common-crawlers\/#google-extended\">Google-Extended<\/a><br \/>\n  in robots.txt to control, among other things, whether their content helps train future versions of<br \/>\n  Gemini models. Utilizing Google-Extended doesn&#8217;t affect a site&#8217;s inclusion in Search, nor do we<br \/>\n  use Google-Extended as a ranking signal in Search.\n<\/p>\n<p>\n  We provide many tools for site owners to manage their Google crawling experience, including<br \/>\n  <a href=\"https:\/\/search.google.com\/search-console\/about\" class=\"external-link\">Google Search Console<\/a>,<br \/>\n  which is available at no cost to site owners. It provides information on<br \/>\n  <a href=\"https:\/\/support.google.com\/webmasters\/answer\/9679690\" class=\"external-link\">how much we&#8217;ve crawled, and why<\/a>.<br \/>\n  It also helps sites diagnose problems such as server downtime or speed issues. In addition, Search<br \/>\n  Console provides comprehensive information on how a site&#8217;s pages are visible in Search and how<br \/>\n  users are engaging with them.\n<\/p>\n<p>\n  Our crawlers help connect people to the best of the web, and we&#8217;re always looking for ways to make<br \/>\n  them more capable and efficient.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn about how Google crawls the web.<\/p>\n","protected":false},"menu_order":7000,"template":"","meta":{"footnotes":""},"ar_kb_kategori":[708],"ar_kb_etiket":[],"class_list":["post-25707","ar_kb","type-ar_kb","status-publish","has-post-thumbnail","hentry","ar_kb_kategori-crawling-infrastructure-crawling-and-indexing"],"_links":{"self":[{"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/ar_kb\/25707","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/ar_kb"}],"about":[{"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/types\/ar_kb"}],"version-history":[{"count":0,"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/ar_kb\/25707\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/media\/27674"}],"wp:attachment":[{"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/media?parent=25707"}],"wp:term":[{"taxonomy":"ar_kb_kategori","embeddable":true,"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/ar_kb_kategori?post=25707"},{"taxonomy":"ar_kb_etiket","embeddable":true,"href":"https:\/\/alienroad.com\/wp-json\/wp\/v2\/ar_kb_etiket?post=25707"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
