The definition of search engines has no more secrets for you! And if you want to tame them on topics like SEO, Neocamino is at your service! A search engine works automatically thanks to robots. You can also find the term «crawler» or «spider» to refer to these robots. Example: Search engine in the web zone. You program your search engine like a GPS by giving it keywords that describe the websites you want to visit! A search engine is a computer program that returns a list of results from a user`s query. A search engine consists of two main elements: search engines are an economic subject. The market value of the holding company Alphabet, owner of Google, the main search engine, was $ 831 billion in April 2020[1]. According to W3C recommendations, more and more content producers are indexing their databases with metadata or taxonomies (ontologies) on the Semantic Web so that search engines can adapt to semantic analysis. Tool (A tool is a closed© object used© by a living being to increase its web search, consisting© of «robots», also called bots©, spiders, crawlers or agents who search for websites at regular intervals©and automatically (automation is part of engineering©. This discipline deals with the…) (without human intervention, which distinguishes them from©directories) to cover new addresses (URLs).
They follow the hypertext links (which link the pages) that are found© on each page reached. Each identified©page is then indexed© in a database (in computer science, a database© (Abr. : «BD» or…), then accessible to Internet users from keywords©. A search engine is an application that allows you to find web pages (or other resources such as images, videos, files…) that are linked to a keyword (or keyword phrase). The operation between a search engine and a directory seems identical to you and it is difficult for you to see the difference. Note that unlike search engines, directory data is created manually. The user must take the initiative to register his website in the directory. Then, a documentary filmmaker is responsible for the classification of the site. For search engines, indexing is automatic. In a directory, the search is therefore carried out on websites and subcategories, while it is carried out for a search engine on texts and web pages in their entirety. Some engines have also introduced a carbon neutrality policy, such as Google, DuckDuckGo and Ecosia.
Google says it will be carbon neutral by 2030, in part by buying renewable energy, and by 2017, the company will buy back as much as it consumes. In the early 2020s, Google is the world`s largest private buyer of this type of energy. Because renewables are essentially intermittent, Google can`t use them directly or permanently: a company that claims to be carbon neutral actually uses «renewable origin guarantees» that ensure that the carbon-based energy it consumes is offset by equivalent renewable energy production. However, according to The Shift Project, Google`s business model needs more and more computing power to renew and expand its infrastructure, networks and devices, the production of which is a major source of greenhouse gases. For the association négaWatt, Google`s communication focuses on use, but overshadows the environmental problems related to the extraction, transport and recycling of resources[7][8]. The ecosia search engine uses 80% of its advertising revenue for reforestation projects around the world[9]. In practice, a search engine is your GPS to move you on the Internet road network. It guides you through your travels on the Internet: quotation marks allow you to search for a specific expression.
