Understanding how Google works

This indexing is done by a software program called spiders, spiders start by fetching a few web pages and they follow the links on those pages and fetch the new web page they just found. This process continues to bring new web page and web content in index of Google

Understanding how Google works should be the first step towards developing a great website.
(just in case you want visitors from Google search)

According to Google when you do a Google search, you are actually searching the Google index of web pages, and not the live web. http://www.google.com/howgoogleworks/#watch

This indexing is done by a software program called spiders, spiders start by fetching a few web pages and they follow the links on those pages and fetch the new web page they just found. This process continues to bring new web page and web content in index of Google.

As you know, internet has got many billions of websites and they all are talking about different things in different languages. Maintaining an index of all known websites is a huge task and Google does that by creating several layers of indexes.

If we assume that there is a layer “A” open for public search, another layer “B” that is kind of backup and layer “C” that is for catch.

Indexing software spiders should be interacting with layer “C” and once they reach the limit of new updated content, another program governed by ranking algorithm (based on website ranking logic) starts work for giving a specific point to each page (page value assignment). Once this process is over, “A” layer updates it self with layer “C”. Here they must have kind of quality check on this new updated index, if everything is fine they move to get new content from the internet. Just incase they find that something went wrong and results are not correct, they can always update layer “A” with backup layer “B” to restore old index.

Now, we have to understand the concept of search so we can better understand how it works.

Google or any responsible search engine wants to show results based on the demand by the user. Let’s take an example; I want to search for a local SEO company in Bangalore. What should I search for?

I will open google.com and will search for “seo company in Bangalore”, is not it? Now Google will look for all the pages available in its layer “A” where there is word “SEO Company in Bangalore”, they will check the quality, page rank and other relevant check lists associates with this search term and show me a list of websites shorted in a relevancy order.

A search result takes about half a second but in this half second, software programs do check billions of pages, run hundreds of quality checks before producing the actual result. 

These software programs are fast and smart, and they need to be updated continually to fight with ever growing leg pullers.

I am going to explain this in detail with examplesFree Web Content, stay tuned…
