Understanding What is Crawler in SEO
A crawler, also called a web crawler, spider, or bot, is a program that search engines like Google use. It scans and indexes content from websites.
These crawlers move around the web. They follow links from one page to another. They collect data and store it in the search engine’s database for indexing.
When we ask, “what is crawler in SEO?”, we are essentially referring to the process search engines use to explore websites and determine how they should be ranked in search results.
Crawlers help search engines understand the structure, relevance, and quality of a website’s content.
How Does a Crawler Work?
To fully grasp what is crawler in SEO, it’s important to understand its working mechanism.
A crawler follows a systematic process to gather and index web content:
- Discovery
The crawler starts by visiting a set of known web pages (seed URLs) and follows internal and external links to discover new content.
- Crawling
The bot scans the HTML structure of each page, identifying important elements such as text, images, and metadata.
- Indexing
After a search engine crawls a page, it processes and stores the page’s information. This makes the information available for search queries.
- Ranking
Search engines look at indexed pages. They check for relevance, quality, and ranking factors. This helps them decide where to place pages in search results.
Crawlers keep repeating this process. This helps search engines have the latest information about websites on the internet.

The Significance of Crawler
Now that we’ve defined what is crawler in SEO, it’s essential to understand its significance:

Without crawlers, search engines cannot find and index web pages. This means those pages won’t show up in search results.

Proper crawling ensures that a website’s content is available for ranking in search queries, leading to better visibility.

Crawlers analyze website structure, helping search engines rank sites that provide a better user experience.

Frequent crawling allows search engines to update their index with fresh content, which is essential for SEO rankings.

This file controls how crawlers access certain parts of a website, preventing unnecessary pages from being indexed.
