9. How Crawler Based SE
Works?
Crawling
Crawling pages is done by
search engine automated
robots, commonly referred to
as “spiders”.
The spiders “read” one page
and then follow any links
from that page to another
page. Through links the
spiders can reach billions of
interconnected documents.

10. How Crawler Based SE
Works?
Indexing
Indexing is the process by which search engines select pieces of relevant code
(including keywords and surrounding text) from the web page and catalog them. They
store that code and related information in data centers from around the world.
Retrieving
Retrieving comes into play when a search engine user types in a keyword or a string of
keywords. The search engine goes into action retrieving all of the URL’s that it has
stored which are relevant to the keyword and returns this information to the user.
Ranking
Ranking of web pages is essential for the satisfaction of the user’s query. Search
engines rank each web page that they find according to things like trust factors, page
rank and even go as far as considering the user’s search history and where they are
geographically located.
Over 200 factors are considered before providing results to the user.
