How Search Engines Work

To understand SEO, you first need to understand how search engines work.

Search engines like Google follow three main steps:

1
Crawling

Google uses bots to scan websites on the internet and discover new pages and content.

2
Indexing

After scanning your website, Google stores your website pages in its database. This is called indexing.

3
Ranking

When someone searches on Google, Google shows results based on relevance, quality, content and many ranking factors. This is called ranking.

SEO helps your website in all three steps:

  • Helps Google find your website
  • Helps Google understand your content
  • Helps your website rank higher

How SEO Works Step by Step

SEO works through multiple activities that improve your website over time.

1

2
Content Creation

All these steps together help improve website ranking on Google.
