Caching & Indexing

Tuesday 17 May 2011


What is the difference between Indexing and Caching?

Indexing is a process to make a webpage searchable on search engine whereas the process of caching refers to providing a reprinting content snapshot.

For example, 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 (by giving priority to the h1, h2, or bold, title, meta tags etc.), it will not place content as it was published. As a result, the site will appear in search results for optimized keywords.

Google also takes a snapshot of each page on a website and stores it in a different data base which is known as cache data base. If you click on the “Cached” link, you will see the web page as it looked when we indexed it. while, Google creates the index and the database of documents that it accesses when processing a query.

  =============   How long to get indexed   =================

There is No set time in for Google to initially index your site - the time taken can vary.
The time it does take may vary based upon factors such as;

   * Popularity of the site (Whether it has any links to it)

   * Whether the content is Crawl-able (Server Responses and Content type)

   * Site structure (how pages interlink)

It is possible for a site to be crawled/indexed within 4 days to 4 weeks.
In some cases, it may take longer.
