Why Must Google Index A Blog Or Website?

I received an email from Mott just a few days ago. It contained an interesting question that we decided to share it to whoever may need it. If there’s anything that you guys would like to add, please leave a comment below.

Why must Google index a blog..or website. Can you tell me, in layman’s term the purpose of this?

“Search engine indexing entails how data is collected, parsed, and stored to facilitate fast and accurate retrieval.” (source)

We use Google to quickly and accurately search for related web pages that we need. In order to do that, Google needs to “crawl” through the Internet, collect and store these web pages. A certain “set of rules” are used during the process of storing these web pages to allow search results to be more accurate. (This process is called indexing)

If Google doesn’t index a particular website/blog/forum etc, that particular web page will not show up when a user searches for it.

Just to add some extra info: When people talk about SEO or search-engine-optimization, they are concentrating on how to design a certain web page so that Google will index and give it a “higher priority” compared to other web pages. Each web page’s “priority” is defined as page rank (PR). PR ranges from 0 to 10. The higher the number, the higher your priority will be thus showing up higher in search results.

For example, search for make money and you will notice 5xmom‘s blog there in the top 10. That is because her blog ranks high for the term make money.


If there’s anything that anyone would like to add or if there’s any factual mistakes I’ve made, please leave a comment below. Thanks.
