What is Crawling and Indexing in Search Engine?

SEO is more than just keywords and backlinks—at its core lies two crucial processes: Crawling and Indexing. If you truly want to take control of your website’s visibility on search engines, you must first understand how these processes work. Let's break it down in a simple, informative way.

What is Crawling in SEO?

Crawling is the process where search engines, like Google, send out bots (also known as spiders or web crawlers) to discover publicly available web pages. These bots scan the internet 24/7, following links from one page to another, collecting data about websites.

Key Highlights:

• Google's crawler (Googlebot) visits websites and gathers a list of URLs from links and sitemaps.
• Crawling is how search engines discover new or updated pages.
• The bot checks the robots.txt file to see which pages it is allowed to access.

Why Crawling Matters:

If your site isn’t being crawled, it won’t be discovered by search engines—meaning it won’t show up in search results at all.

What is Indexing in SEO?

Indexing is the next step after crawling. It’s when Google decides whether or not to include a page in its search index—a huge database of web content that it draws results from when users type queries into Google.

How It Works:

• After crawling, Google evaluates your page content.
• It checks the meta tags (like index or noindex) to determine if the page should be added to the search index.
• If it passes the checks, the page is indexed and eligible to appear in search results.

If your page has a noindex tag:

Google may crawl it, but it will not be indexed, meaning it won’t appear in search results.

What is a Web Crawler?

A Web Crawler (or spider) is a type of software that systematically browses the web for the purpose of web indexing. Google’s version is called Googlebot. These crawlers are programmed to analyze the structure and content of web pages.

Factors That Affect Crawling and Indexing
