Understand what is Crawling and Indexing in SEO

1. CRAWLING
AND
INDEXING

3. In the simplest terms, you could think of searching the
web as looking in a very large book with an impressive
index telling you exactly where everything is located.
When we perform a Google search, Google programs
check their index to determine the most relevant
search results.
There are three process in delivering search results.
1. Crawling – Does Google know about your site and
find it.
2. Indexing – Can Google index your site.
3. Serving – Does the site have good and useful content
that is relevant to search users.

4. CRAWLING
 Crawling is the process of fetching all the web pages
linked with a website.
 This task is performed by a software called crawler.
The crawlers are also known as spiders or bots , they
visit website and send information to their respective
parent websites.

5. INDEXING
 Indexing is the process of creating index for all the
fetched web pages and keeping them into a huge
database from where it can later be retrieved.
 An index is another name for the database used by
a search engines. It contains information on all
the websites the search engine was able to find. If a
website is not in a search engine’s index, users will not
be able to find it using that search engine. Search
engines regularly update their indexes.

6. Difference between Indexing and
Crawling
 Crawling is the process through which indexing is
done. Google crawlers crawls through the WebPages
and index the pages.
 When search engine crawlers visit any link is called
crawling and when crawlers save or index that links in
search engine database is called indexing.

7.  Crawling means to visit the link by Search engines and
indexing means to put the page contents in Database
(after analysis) and make them available in search
results when a request is made.
 Crawling means the search engine robot crawl or fetch
the web pages while Indexing means search engine
robot crawl the web pages, saved the information and
it appear in the search engine.
