Crawling
Quick Definition
Crawling is the process by which search engine bots (like Googlebot) discover web pages by following links across the internet. A page must be crawled before it can be indexed and appear in search results.
Why It Matters
Crawling is the very first step in how search engines work. If a search engine cannot crawl your page, it cannot index it, and it will never appear in search results. Understanding crawling helps you diagnose why pages might not be showing up in Google and how to fix common crawling issues.
Real-World Example
Think of Googlebot as a librarian who visits websites by following links from page to page. It starts at known pages, follows every link it finds, reads the content, and reports back to Google. If your page has no links pointing to it and is not in your sitemap, Googlebot may never find it.
Signal Connection
Presence -- Crawling is the absolute foundation of search presence. A page that is not crawled cannot exist in search results. Ensuring your pages are crawlable is the first requirement for any SEO strategy.
Pro Tip
Check your Crawl Stats in Google Search Console (Settings > Crawl Stats) to see how many pages Google crawls daily on your site. If important pages are not being crawled, submit them via URL Inspection or add them to your XML sitemap.
Common Mistake
Blocking important pages from crawling using robots.txt and then wondering why they do not rank. If robots.txt disallows a URL, Googlebot will not crawl it, and it cannot be indexed. Always verify your robots.txt is not accidentally blocking important content.

Answer: B. The page cannot be indexed and will not appear in search results at all
Crawling is a prerequisite for indexing. If Googlebot cannot access and crawl a page, it cannot add it to Google's index, which means the page will never appear in search results for any query.
