A By guessing URLs randomly

B By manually adding pages one by one

C By scanning only social media posts

C Sitemaps speed up page loading for users

🔍 Analysis

Why might Google not crawl some pages even if they are linked?

Google may choose not to crawl certain pages even if they are linked from other pages. Which of the following is NOT a reason for this?

A The page is blocked by robots.txt

B The page has many internal links pointing to it

C The page has a very slow loading time

D The page has a 'noindex' meta tag

💡 Hint

Consider what might prevent Google from crawling a page.

Google may skip crawling pages blocked by robots.txt, marked 'noindex', or very slow to load. Having many internal links usually encourages crawling, not prevents it.

❓ Comparison

advanced

Compare crawling frequency for different types of pages

Which type of page is Google likely to crawl more frequently?

A A page blocked by robots.txt

B An old page with no changes for years

C A homepage that updates daily

D A page with a 'noindex' tag

💡 Hint

Think about how often Google revisits pages that change often versus those that don't.

Google crawls pages that update frequently more often to keep its index fresh. Pages blocked or marked 'noindex' are not crawled or indexed.

❓ Reasoning

Google has limited resources to crawl billions of pages. Which factor below best explains how Google decides which pages to crawl first?

A Pages with higher PageRank or importance get crawled earlier

B Pages with the longest URLs are crawled first

C Pages with fewer images are crawled first

D Pages that use more keywords in the title are crawled first
