Google - The world's most popular search engine.

PageRank Google's rise to success was largely due to a patented algorithm called PageRank that helps rank web pages that match a given search string.

Previous keyword-based methods of ranking search results, used by many search engines that were once more popular than Google, would rank pages by how often the search terms occurred in the page, or how strongly associated the search terms were within each resulting page.

The PageRank algorithm instead analyzes human-generated links Serach engine that web pages linked from many important pages are themselves likely to be important. The algorithm computes a recursive score for pages, based on the weighted sum of the PageRanks of the pages linking to them.

PageRank is thought to correlate well with human concepts of importance. In addition to PageRank, Google, over the years, has added many other secret criteria for determining the ranking of pages on result lists.

This is reported to comprise over different indicators, [12] [13] the specifics of which are kept secret to avoid difficulties created by scammers and help Google maintain an edge over its competitors globally.

In a potential hint of Google's future direction for their Search algorithm, Eric SchmidtGoogle's then chief executive, said in a interview with the Financial Times: Google says it wants its users to have access to premium quality websites.

Those websites which lack a mobile friendly interface would be demoted and it is expected that this update will cause a shake-up of ranks. Businesses who fail to update their websites accordingly could see a dip in their regular websites traffic.

Search engine optimization Because Google is the most popular search engine, many webmasters attempt to influence their website's Google rankings. An industry of consultants has arisen to help websites increase their rankings on Google and on other search engines.

This field, called search engine optimizationattempts to discern patterns in search engine listings, and then develop a methodology for improving rankings to draw more searchers to their clients' sites. Search engine optimization encompasses both "on page" factors like body copy, title elements, H1 heading elements and image alt attribute values and Off Page Optimization factors like anchor text and PageRank.

The general idea is to affect Google's relevance algorithm by incorporating the keywords being targeted in various places "on page", in particular the title element and the body copy note: Too many occurrences of the keyword, however, cause the page to look suspect to Google's spam checking algorithms.

Google has published guidelines for website owners who would like to raise their rankings when using legitimate optimization consultants. According to Google, it was not the frequently published consumer complaints about DecorMyEyes which resulted in the high ranking but mentions on news websites of events which affected the firm such as legal actions against it.

Google Search Console helps to check for websites that use duplicate or copyright content.

Prior to Universal search, a standard Google search would consist of links only to websites. Universal search, however, incorporates a wide variety of sources, including websites, news, pictures, maps, blogs, videos, and more, all shown on the same search results page.

The new architecture provided no visual differences in the user interface, but added significant speed improvements and a new "under-the-hood" indexing infrastructure. The move was interpreted in some quarters as a response to Microsoft 's recent release of an upgraded version of its own search service, renamed Bingas well as the launch of Wolfram Alphaa new search engine based on "computational knowledge".

Knowledge Graph The Knowledge Graph is a knowledge base used by Google to enhance its search engine's results with information gathered from a variety of sources. Google Hummingbird InGoogle significantly upgraded its search algorithm with "Hummingbird".

Its name was derived from the speed and accuracy of the hummingbird. The change was a response to the continued growth in mobile usage, and a push for web developers to adopt a mobile-friendly version of their websites.

As per current analysis done by the industry leaders SearchEngineWatch and SearchengineLand, the update was to drop down the medical and health related websites that were not user friendly and were not providing good user experience. This is why, the industry experts named it "Medic".

This is because misinformation can affect users financially, physically or emotionally. Therefore, the update targeted particularly those YMYL pages that have low-quality content and misinformation. This resulted in the algorithm targeting health and medical related websites more than others.
