Hello,

What is difference between crawling, indexing and caching?

How caching, crawling and indexing works. Which one has higher priority? How methods are carried out. What Google do? Does it first caches the pages/websites or crawl the data on the page.

Note: Please do not post any definition or Wikipedia article as a source. Replies from senior member will be appreciated.

In laymans terms:
Google crawls your site and then indexes what it sees as a cached version of the page.
The page may change in design before they crawl and then reindex the new page hence the term cache is used as almost a caveat to say that the page may've changed since they crawled it.
If your webpages aren't crawled then they can't be indexed. Making sure your site can be crawled by bots is a priority. Set up a Google Webmaster Tools account and then submit a XML sitemap to help Google crawl and index it.
Hope that helps.

Crawling- Google sends its spiders to your website..
Indexing- Google visited your website and has added you to its database..

Caching- Google toook a snapshot of your website when it last visited and stored the data in case your website went down or if there are some any other issues.

Crawling is the process of an engine requesting — and successfully downloading — a unique URL.
Indexing is the result of successful crawling. I consider a URL to be indexed (by Google) when an info: or cache: query produces a result, signifying the URL’s presence in the Google index.
It means, if we uploaded a new website, then first of all search engine crawler will read the site and after that, it will store all its contents in its Index Data Base in a different format, it will not place content as it was published. As a result, the site will appear in search results for optimized keywords.

Crawling is something like Search engine bots visited your site and indexing is saving your information in database and caching is the more detail information of indexing like when visited and time , now you can know which goes first.
