What is the difference between crawling and Indexing?
 

Hello Friends,

What is the difference between Crawling and Indexing? Is it necessary that my website will be Crawled as well as Indexed?

crawling means gathering information related topic and indexing means arrange topic quality wise

Crawling and indexing both are different thing. When search engine found and read website that call crawling and when search engine index your website data that call indexing.

crawling means collecting information to the related topic and indexing means to arrange in sequence

What is the difference between crawling and Indexing?
 

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.

hi hi, i know the diffirent both :)

Without crawling indexing is not possible. When a new website/webpage arrives it is first crawled for indexing by search spiders.

Crawling takes place when there is a successful fetching of unique URIs which can be traced from valid links from other web pages. It’s like Pacman following all those dots and eating them, only that in the case of crawling, it’s the search engine robots that follow the links.

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. The following reasons could be the causes of non-indexing of a previously crawled page:

Crawling means to visit the link by SEs and indexing means to put the page contents in DB (after analysis) and make them available in search results when a request is made

Crawling means sucking content without processing the results. Crawlers are rather dumb processes that fetch content supplied by Web servers answering (HTTP) requests of requested URIs, delivering those contents to other processes, e.g. crawling caches or directly to indexers. Crawlers get their URIs from a crawling engine that’s feeded from different sources, including links extracted from previously crawled Web documents, URI submissions, foreign Web indexes, and whatnot.

Indexing means making sense out of the retrieved contents, storing the processing results in a (more or less complex) document index. Link analysis is a way to measure URI importance, popularity, trustworthiness and so on. Link analysis is often just a helper within the indexing process, sometimes the end in itself, but traditionally a task of the indexer, not the crawler (high sophisticated crawling engines do use link data to steer their crawlers, but that has nothing to do with link analysis in document indexes).

was different , I think the same

crawl & index are both same thing.

Crawling is the initial step, And Indexing is the final step.
