In indexing, one can distribute backlinks to different website whereas in crawling search engine robots crawls you backlinks which affect the ranking of your website in search engine.

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

When search engines look through the content on your website, they are crawling your site. As they crawl your site, they index content that will appear in the search engine. However, an important thing to remember is that not all content is indexed. Search engines pick what content they will and won't index as they go through the crawling process.

Crawling is when a search engine bot visits your site
Indexing is when a search engine bot visits your site first time and takes a copy of your site to its database.

Indexing is the process of creating indexes for record collections.  Having indexes allows researchers to more quickly find records for specific individuals; without them, researchers might have to look through hundreds or thousands of records to locate an individual record.

Crawling process is a final process of through which Google gives final results for your website or blog. This is a process execute by search engine spiders when searching for relevant websites on the internet.

Crawling and indexing is both the part of Google algorithm term.both are refer for unique Content on website.


CRAWLING
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.

I say crawling takes place on a successful fetching because not all links we see on the Web are crawlable. The following cases may be the reasons why links can't be crawled:

1. Link coding is in JavaScript format which is otherwise known as spider trap
2. Link was marked for exclusion via robots.txt's disallow directive
3. Orphaned link (no one linked to it and the absence of sitemaps.xml that include such link)
4. Link is found within a page that contains the nofollow directive
5. Server was down when link was supposed to be crawled.

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:

1. A noindex directive in the page (<meta name="robots" content="noindex" />)
2. Duplicate content: a page that has the same content as with an indexed page may not be indexed.

Other reasons such as link age and link popularity may also play a role but I am less inclined to lean on them.
