Unlike search engine software, web directories store the links of those websites in their directory, which is given to keep them. In other words, it can be said that web directories search the entire web (www) like search engines. Instead of storing the addresses of available websites in themselves, they hold only the URLs of those websites asked to keep.
When a user tries to find the URL of a website using the web directory, then by searching the keywords given by the users in their guide, they try to find the URL of the website in which those keywords are found. For example, Yahoo is a web directory with its URL – https://www.yahoo.co.in ).
3). Hybrid Search Engine
Those websites can be included in the category of hybrid in which the properties of both search engines and web directories are found. They actively search in the whole www, and they also have their manuals from which they can also do their search. Infoseek is an example of a similar search site whose URL is – https://www.infoseek.com.
4). Metasearch Engine

By clicking on these hyperlinks, we can access those web pages. A search engine works in the following three steps:-
Also known as Robot and Spider is a unique program that continuously scans the Internet’s website and gets the information available there. After collecting the data from any webpage, Crawling means that the spider continues its search by clicking on other links present there.
These programs constantly roam the web and make it easy to search engines.
This process occurs when the data is processed and placed in the database after crawling. The index works like a catalog where the information obtained from the searched web page is collected. By exploring the character string made by the users in this index, the link of the page displays the result format.
