Google allows users to search the Web for images, news, products, video, and other content. We would like to show you a description here but the site won’t allow us.
The first step is finding out what pages exist on the web. There isn't a central registry of all web pages, so Google must constantly search for new pages and add them to its list of known pages.
Some pages are known because Google has already visited them before. Other pages are discovered when Google follows a link from a known page to a new page. Still other pages are discovered when a website owner submits a list of pages a sitemap for Google to crawl. If you're using a managed web host, such as Wix or Blogger, they might tell Google to crawl any updated or new pages that you make.
Once Google discovers a page URL, it visits, or crawlsthe page to find out what's on it. Google renders the page and analyzes both the text and non-text content and overall visual layout to decide where it should appear in Search results.
The better that Google can understand your site, the better we can match it to people who are looking for your content. After a page is discovered, Google tries to understand what the page what is a male relation by marriage called about. This how to restring a fender telecaster is called indexing.
Google analyzes the content of the page, catalogs images and video files embedded on the page, and otherwise tries to understand the page.
This information is stored in the Google indexa huge database stored in many, many many! When a user types a query, Google tries to find the most relevant answer from its index based on many factors. Google tries to determine the highest quality answers, and factor in other considerations that will provide the best user experience and most appropriate answer, by considering things such as the user's location, language, and device desktop or phone.
For example, searching for "bicycle repair shops" would show different answers to a user in Paris than it would to a user in Hong Kong. Google doesn't accept payment to rank pages higher, and ranking is done programmatically.
Crawling is the process by which Googlebot visits new and updated pages to be added to the Google index. We use a huge set of computers to fetch or "crawl" billions of pages on the web. The program that does the fetching is called Googlebot also known as a robot, bot, or spider. Googlebot uses an algorithmic process to determine which sites to crawl, how often, and how many pages to fetch from each site. Google's crawl process begins with a list of web page URLs, generated from previous crawl processes, augmented by Sitemap data provided by website owners.
When Googlebot visits a page it finds links on the page and adds them to its list of pages to crawl. New sites, changes to existing sites, and dead links are noted and used to update the Google index. During the crawl, Google renders the page using a recent version of Chrome.
As part of the rendering process, it runs any page scripts it finds. Googlebot processes each page it crawls in order to understand the content of the page. Googlebot can process many, but not all, content types. For example, we cannot process the content of some rich media files. Somewhere between crawling and indexing, Google determines if a page is a duplicate or canonical of another page.
If the page is considered a duplicate, it will be crawled much less frequently. Similar pages are grouped together into a document, which is a group of 1 or more pages that includes what year was the first hess truck sold canonical page the most representative of the group and any duplicates found which what is new in google search simply be alternate URLs to reach the same page, or might be alternate mobile or desktop versions of the same page.
Note that Google doesn't index pages with a noindex directive header or tag. However, it must be able to see the directive; if the page is blocked by a robots. Internally, Google represents the web as an enormous set of documents.
Each what is new in google search represents one or more web pages. These pages are either identical or very similar, but are essentially the same content, reachable by different URLs.
The different URLs in a document can lead to exactly the same page for instance, example. The document's canonical URL is the one that Google crawls and indexes most often; the other URLs are considered duplicates or alternatesand lyrics what do you mean justin bieber occasionally be crawledor served according to the user request: for instance, if a document's canonical URL is the mobile URL, Google will still probably serve the desktop alternate URL for users searching on desktop.
You can tell Google which URL you prefer to be canonicalbut Google may choose a different canonical for various reasons. When a user enters a query, our machines search the index for matching pages and return the results we believe are the most relevant to the user. Relevancy is determined by hundreds of factors, and we always work on improving our algorithm. Google considers the user experience in choosing and ranking results, so be sure that your page loads fast and is mobile-friendly.

Here is a short version and a long version. Google gets information from many different sources, including: Web pages, User-submitted content such as Google My Business and Maps user submissions, Book scanning, Public databases on the Internet, and many other sources. However, this page focuses on web pages.
The short version Google follows three basic steps to generate results from web pages: Crawling The first step is finding out what pages exist on the web. To improve your site crawling: Verify that Google can reach the pages on your site, and that they look correct. Google accesses the web as an anonymous user a user with no passwords or information.
Google should also be able to see all the images and other elements of the page to be able to understand it correctly. If you've created or updated a single page, you can submit an individual URL to Google.
To tell Google about many new or updated pages at once, use a sitemap. If you ask Google to crawl only one page, make it your home page. Your home page is the most important page on your site, as far as Google is concerned. To encourage a complete site crawl, be sure that your home page and all pages contain a good site navigation system that links to all the important sections and pages on your site; this helps users and Google find their way around your site.
For smaller sites less than 1, pagesmaking Google aware of only your homepage is all you need, provided that Google can reach all your other pages by following a path of links that start from your homepage. Get your page linked to by another page that Google already knows about. However, be warned that links in advertisements, links that you pay for in other sites, links in comments, or other links that don't follow the Google Webmaster Guidelines won't be followed by Google.
Indexing After a page is discovered, Google tries to understand what the page is about. To improve your page indexing: Create short, meaningful page titles. Use page headings that convey the subject of the page. Use text rather than images to convey content. Google can understand some image and video, but not as well as it can understand text. At minimum, annotate your video and images with alt text and other attributes as appropriate.
Serving and ranking When a user types a query, Google tries to find the most relevant answer from its index based on many factors. To improve your serving and ranking: Make your page fast to load, and mobile-friendly.

Here it is: The long version Crawling Crawling is the process by which Googlebot visits new and updated pages to be added to the Google index. How does Google know which pages not to crawl? Pages blocked in robots. Google can infer the content of the page by a link pointing to it, and index the page without parsing its contents.
Google can't crawl any pages not accessible by an anonymous user. Thus, any login or other authorization protection will prevent a page from being crawled. Pages that have already been crawled and are considered duplicates of another page, are crawled less frequently. Improve your crawling Use these techniques to help Google discover the right pages on your site: Submit a sitemap. Submit crawl requests for individual pages. Use a simple, human-readable, and how to work in the embassy URL paths for your pages and provide clear and direct internal links within the site.
If you use URL parameters on your site for navigation, for instance if you indicate the user's country in a global shopping site, use the URL parameters tool to tell Google about important parameters.
Use robots. Use hreflang to point to alternate versions of your page in other languages. Clearly identify your canonical page and alternate pages. View your crawl and index coverage using the Index Coverage Report. Be sure that Google can access the key pages, and also the important resources images, CSS files, scripts needed to render the page properly. Confirm that Google can access and render how to get into horse racing ownership page properly by running the URL Inspection tool on the live page.
Indexing Googlebot processes each page it crawls in order to understand the content of the page. Improve your indexing There are many techniques to improve Google's ability to understand the content of your page: Prevent Google from crawling or finding pages that you want to hide using the noindex tag. Do not "noindex" a page that is blocked by robots.
Use structured data.

I like to think of a knowledge graph as a cross between an encyclopedia and a database. A topic can be about anything. However, Google also states that while the information in the above list might be available directly in their search API, they augment this data considerably internally.
It also supports the machine in retrieving the right information at the right time when a person asks for example. There are many knowledge graphs in the world. The Google knowledge graph is just one. Others include dbpedia. Indeed, any semi-structured data could be described as a knowledge graph, including encyclopedias or databases like IMDB. Google is known to have built out its knowledge graph initially from other data sets including Wikipedia and the CIA Factbook. This is not the case, although the Knowledge panel may represent a subset of data in the graph.
A final disambiguation is in the terminology. This article will use the phrases interchangeably. Any entity is generally given a topic type. Many others are listed on their Knowledge Graph Search API developer page, but Google currently seems quite weak at correctly categorizing many entities. These include scale, diversity, information integrity, and speed.
The number of webpages is a hotly contested subject and while many argue they are countless, they are certainly in the trillions and expanding at a vast rate every day. By contrast, the number of topics understood by humanity is much smaller perhaps in the order of hundreds of billions and is growing at a far smaller rate. This means that there is an inordinate duplication of ideas in the content on the web.
Storing information about a topic allows Google to cite multiple data sources, rather than always sending the user to a single webpage. In addition, information about a topic can in theory be derived from other sources beyond the Internet. A new fact about a topic may have to pass some quality threshold before it is added to the Knowledge Graph, but these thresholds are unlikely to be discussed openly by Google.
On the negative side, a single point of truth can reduce the diversity of information and can be prone to bias if the underlying data sources are themselves biased. By organizing information by topic, it becomes much faster to retrieve information — both by Google and by the user looking for a needle in a haystack. Google can use information about your behavior to understand what Topics are important to you and can surface-related topics based on user history.
Topics can also be seen in Google Trends. From here, Google also gives an indication of topics that might be closely related to each other, although it appears that this data is currently gleaned from pulling other searches by the same users, which can sometimes lead to rather unexpected related Topic lists. This is often at the expense of the core search results, pushing links to websites way below the fold.
These answers are also then in a format that Google can use in voice search. The Priscilla screenshot is an example of this:. Entities also are highly visible in Image Search, often grouping images around a notable person or place in particular. This is an excellent example of how the Knowledge Graph can be used to act as a repository for other data sources than webpages.
