How Does SEO Work?
It is much easier for you to understand what is SEO if you know how search engines find and rank web pages. The procedure is complicated, but it can be summarized in 4 basic steps: crawling, indexing, ranking, and matching search intent.
As a beginner, you are not required to memorize all the technical aspects. But these basics certainly help you learn the basics of Search Engine Optimization.
Crawling
Crawling is the first step of the SEO process. Search engines have bots that go out and find the new pages, update old ones on the World Wide Web. These bots are sometimes called crawlers.
These bots follow links between pages and collect information about:
- Website content

- Internal links
- Page structure
- Metadata
A website that is properly linked and simple to navigate helps the search engine crawl more efficiently.
Indexing
The page will then be crawled, and search engines will inspect the page to check if it is suitable to be stored in their database (the Index).
During indexing, search engines evaluate factors such as:
- Content quality
- Originality
- Relevance
- Website structure
- User experience

Ranking
A page ranks in search results for various keywords once it has been indexed.
Ranking depends on many signals, including:
- Content relevance
- Page quality
- Website authority
- User experience
- Mobile friendliness
- Page speed
The aim is to deliver to the user the most relevant and trustworthy answer they are looking for.
Search Intent
Search intent is the reason a user is looking.
For example:
|
Search Query |
Search Intent |
|---|---|
|
Weather in Kolkata today |
Get current weather information (Informational) |
|
Best smartphones under 30,000 |
Compare products before purchasing (Commercial Investigation) |
|
Buy Nike running shoes |
Purchase a product (Transactional) |
|
Domino’s Pizza near me |
Find a nearby business (Local) |
|
Facebook login |
Navigate to a particular site/page (Navigational) |
If you know what the visitor is searching for, you will be able to produce the correct content for that need, increasing the probability of a good position.
