Crawler-based search engines have three major elements. First is the spider, also called the crawler. The spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being "spidered" or "crawled."

What does a search engine do and how do they work?
There are fundamentally two kinds of web crawlers. The first is by robots called crawlers or creepy crawlies. Web crawlers use insects to record sites. At the point when you present your site pages to an internet searcher by finishing their necessary accommodation page, the web crawler bug will list your whole website. A 'bug' is a mechanized program that is controlled by the web crawler framework. Bug visits a site, reads the substance on the genuine site, the site's Meta labels, and furthermore follows the connections that the site associates. The arachnid at that point restores all that data back to a focal vault, where the information is recorded. It will visit each connection you have on your site and file those destinations also. A few bugs will just record a specific number of pages on your site, so don't make a site with 500 pages! The insect will occasionally re-visitation the locales to check for any data that has changed. The recurrence with which this happens is controlled by the mediators of the web crawler. A bug is practically similar to a book where it contains the list of chapters, the real substance, and the connections and references for all the sites it finds during its hunt, and it might list up to 1,000,000 pages per day.

How does a search engine let you search for information on the web?
How does a search engine let you search for information on the web? There are two different kinds of search engines - one is a crawler-based search engine (spider), and the other type is a human-driven directory - and they both gather and create their listings in extremely different ways. Human Driven Directories (e.g. Open Directory) uses humans to build their listings. One submits a short description for a website to the directory or the directory has editors that write a description for sites they review. Crawler Search Engines (e.g. Google) uses spiders (automated software program that "spiders" the content of a website). The spiders go to a web page, read the content there, and follow any links it comes across along the way until it reaches a dead end. The spiders then index the information it gathers in a giant catalog. Spiders will revisit a site every month or two and update any changes that occur on that site. The final aspect of how the search engines work is the search engine software program goes through the millions of web pages recorded in the index and finds a match to a search ranking them in an order based on what that search engine believes to be most relevant.

On the other hand a search engine is an internet application where you provide some keywords and based on these inputs it returns some results by searching the same copies of the web pages crawled by the crawlers before. Most of them go by matching the text content with your keywords while some also work on tags.
