What is Search Engine?
A search engine is a software system that is
designed to search information’s on the World
The search results are generally presented in a line
of results often referred to as search engine
results pages (SERPs).
The information may be a of web pages, images,
information and other types of files .
Architecture of Search Engines
The architecture of search engine has the following
• Serving Results
Crawling is a process by which Googlebot
discovers publicly available webpages and analyses the
links on those pages by browsing content on the web. The
crawl process begins with a list of web addresses from past
crawls and sitemaps provided by website owners.
The crawler goes from link to link and brings data about
those webpages back to Google’s servers.
(Googlebot -Google Crawler)
The process of saving all the information’s as a
database from those that are collected by the crawler is
The Indexer will have every information that were
crawled such as ,all the words the crawler sees, their location
on each page, key content tags, attributes, internal links,
external links etc..
(Google Page Index is how many pages from your website
that Google has seen and has stored in its database.)
Google essentially gathers the pages during the
crawl process and then creates an index.
The Google index includes information about words
and their locations. When a user search, at the most
basic level, Google’s algorithms look up the search
terms in the index to find the appropriate pages.
The process of fetching out more relevant results
from the Google index, which matches the users query is
called Serving Results.
Based on the users query, Google fetches out
results from the number of pages that google has already
indexed and then displays relevant results to the users

advertising, and you have a keyword phrase that is
on the page 3 times, your keyword density is 3%

determine the importance of a Web Page. It's one
of many factors used to determine which pages
appear in search results.

Page and Sergey Brin at Stanford. The name
PageRank likely comes from Larry Page.
How PageRank is Measured?
PageRank is Google's determination of
how popular your website is compared to other sites
on the web.
It ranks the site on a scale by counting the
number of other sites that link to your site
(Backlinks). The more sites that link to you, the higher
your PageRank will be. Depending on how high the
PageRank of the site that links to you is, the more it
will influence your own page's PageRank.
(Backlinks are considered as votes to rank a page)
What are Google Snippets?
Snippets are the few lines of text that appear under every
search result that are designed to give users a sense of what’s on the
page and why it’s relevant to their query.

content on your site, which can be used to display

the events on your site. The next time Google crawls your
site, the event data will be available for rich snippets on
search results pages

schemas(syntax), i.e., html tags, that webmasters can use ( in
source code) to markup their pages in ways recognized by
major search providers.

description of your website focusing on the areas and
services that your business is specialized in.

For instance – the header tags [h1] [h2] [h3], Bold
[strong], Italic [em] etc.

high importance by the search engine. Usually you can
use them to define the page/post titles or the important
sections of your website.

most important section of your page. Usually Header 1
is used for Site’s title or header text.

titles or important sections of your pages. Separating
your content with headers is a good practice as it makes
your site more readable and easy to navigate.

which are of high importance. Sometimes it’s good to
bold your keywords where appropriate. However
overdoing this may get you penalized.

words which will appear in italic.
