A lot of information is generated and shared on the internet every day. Therefore, it was necessary to create a method of organization and classification to make it easier for people to find what they need and preferably quickly.
And that’s where search engines came in!
They are mechanisms that facilitate quick access to information. Here’s how it works: every time someone does a search, the search engine stores information, keeping browsing data to speed up future access to the page.
The best-known search engines are Google and Bing, but there are others on the market. Keep reading to find out what they are.
A search engine or search site is basically a system responsible for searching for files stored on internet services.
To find these files, search engines identify the keywords used by the user during their search. As a result, they deliver a list of links that lead to sites that mention the searched term.
Here comes the importance of SEO strategies, because in this way we can make our content appear in the first results of search engines.
Types of search sites
Search sites are classified into 3 types, being:
- Directories; Meta search engines;
- Hierarchical Search Engines.
These search engines review the databases of pages through Web crawlers – or spiders, and collect information on content according to the user’s search.
In this way, they classify the results according to their relevance to the search and the person’s browsing history.
Here, site links are grouped by categories. Although they are simple, they require human support and maintenance to function.
This type of site does not crawl or store content, it simply groups links by category organizing them by date of publication.
Meta Search Engines
This interface forwards the search to other search sites and analyzes the results they present.
In this way, the goal of meta search engines is to increase the margin of results and organize the links in an order defined by the structural system.
Types of Search Engines
Vertical Search Engines
Vertical or specialized search engines perform searches for a specific type of content, such as videos, price comparison, blogs and communities.
Or even for a market segment, such as automobiles, services, real estate, tourism among others.
YouTube is an example of a vertical or specialized search site, as it only searches within its 100% video database.
Horizontal Search Engines
Horizontal search sites perform searches on all types of content or information from the World Wide Web, directories, or proprietary or public databases.
Google, for example, is a horizontal search site. Pay attention when doing a search. When you enter and perform your search, it displays consolidated results of web pages, images, videos, among others.
How many search engines exist?
Besides Google, there are more than 20 search engines on the internet. However, many of them are not well-known.
Among the main search engines available on the internet, we can mention:
