Google, in its own words, uses a huge set of computers to crawl billions of pages on the web. This crawler, called the Googlebot, essentially begins with a list of web page URLs generated from previous crawls and then augments those pages with sitemap data provided within Google Search Console. During the crawling process, the Googlebot — also known as a “spider” — looks for new sites, updates to existing pages, and any broken links.
If new pages are within your sitemap, Google will discover them and crawl the content and then potentially list the page within search results based on its evaluation of 200+ criteria.
Once the crawling process is complete, all of the results are fed into Google’s index, and any new sites or updated content will be listed accordingly. During the processing of results, Google looks at information on your page such as title tags, meta description, alt tags, and more. If you have dynamic content on a page, the Googlebot may not be able to read it and will crawl the default version — it’s recommended that your default version is optimized for search.
As a result of Google’s crawling, you may never need to submit your website as it will be discovered automatically. The downside to this approach has always been that it’s reliant on Google’s timeframe to crawl and index your site content, which may not happen as quickly as you would like.
Google LLC is an American multinational technology company that specializes in Internet-related services and products, which include online advertising technologies, a search engine, cloud computing, software, and hardware. It is considered one of the Big Four technology companies, alongside Amazon, Apple and Microsoft.
Google was founded in September 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University in California. Together they own about 14 percent of its shares and control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a California privately held company on September 4, 1998, in California. Google was then reincorporated in Delaware on October 22, 2002. An initial public offering (IPO) took place on August 19, 2004, and Google moved to its headquarters in Mountain View, California, nicknamed the Googleplex. In August 2015, Google announced plans to reorganize its various interests as a conglomerate called Alphabet Inc. Google is Alphabet’s leading subsidiary and will continue to be the umbrella company for Alphabet’s Internet interests. Sundar Pichai was appointed CEO of Google, replacing Larry Page who became the CEO of Alphabet.
The company’s rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Google’s core search engine (Google Search). It offers services designed for work and productivity (Google Docs, Google Sheets, and Google Slides), email (Gmail), scheduling and time management (Google Calendar), cloud storage (Google Drive), instant messaging and video chat (Duo, Hangouts, and Meet), language translation (Google Translate), mapping and navigation (Google Maps, Waze, Google Earth, and Street View), podcast hosting (Google Podcasts), video sharing (YouTube), blog publishing (Blogger), note-taking (Google Keep, and Google Jamboard), and photo organizing and editing (Google Photos). The company leads the development of the Android mobile operating system, the Google Chrome web browser, and Chrome OS, a lightweight operating system based on the Chrome browser. Google has moved increasingly into hardware; from 2010 to 2015, it partnered with major electronics manufacturers in the production of its Nexus devices, and it released multiple hardware products in October 2016, including the Google Pixel smartphone, Google Home smart speaker, Google Wifi mesh wireless router, and Google Daydream virtual reality headset. Google has also experimented with becoming an Internet carrier (Google Fiber, Google Fi, and Google Station).
Google.com is the most visited website in the world. Several other Google services also figure in the top 100 most visited websites, including YouTube and Blogger. Google was the most valuable brand in the world in 2017 (surpassed by Amazon), but has received significant criticism involving issues such as privacy concerns, tax avoidance, antitrust, censorship, and search neutrality.
