Hi Everyone !! What is the difference between crawling and indexing?

[ShreyaKoushik]

Crawling- Crawling takes place when there is a successful fetching of unique URIs which can be traced from valid links from other web pages.

Indexing- Indexing takes place after a crawled URIs are processed. Note that there may be several URIs that are crawled but there could be fewer of them whose content will be processed through indexing.

Ok, If you are post blog any guest posting website and then google come on that website to fetch new links and then google crawling your website(crawling means google has see your website) and google save your links in our data bash so it called indexing.

Crawling is basically when the search engine spider visits a page

Indexing is when the spider records the page and starts displaying the page in search or counting the link for SERP movement.

"Crawling is where search engines spiders / bots move from web page to web page by following the links on the pages. The pages "found" are then ranked using an algorithm and indexed into the search engine database.

Indexing is where search engine has crawled the web and ranks the URLs found using various criteria and places them in the database, or index.
