SEO Technical SEO 4 — Questions and Answers
Question 1: What is the effect of setting 'noindex' in the X-Robots-Tag HTTP header on a page?
- The page is blocked from being crawled
- The page is excluded from search engine indexes (Correct answer)
- The page's links are not followed
- The page is redirected to a canonical URL
Correct answer: The page is excluded from search engine indexes
The noindex directive in X-Robots-Tag or meta robots tells search engines not to include the page in their index.
Question 2: What is the recommended maximum depth (number of clicks from homepage) for important pages to ensure crawlability?
- 1 click
- 3 clicks (Correct answer)
- 7 clicks
- 10 clicks
Correct answer: 3 clicks
SEO best practice recommends keeping important pages within 3 clicks of the homepage to ensure Googlebot discovers and crawls them efficiently.
Question 3: Which of the following is a valid use case for a 410 HTTP status code?
- A page that has moved permanently to a new URL
- A page that has been intentionally and permanently deleted (Correct answer)
- A page requiring a login to access
- A server that is temporarily unavailable
Correct answer: A page that has been intentionally and permanently deleted
A 410 Gone status tells crawlers the resource is permanently deleted, which can speed up removal from the index compared to a 404.
Question 4: What does 'Interaction to Next Paint' (INP) measure?
- The time until the first pixel renders on screen
- The overall responsiveness of a page to user interactions throughout its lifetime (Correct answer)
- The delay before a browser processes the first user input
- The visual stability after a click event
Correct answer: The overall responsiveness of a page to user interactions throughout its lifetime
INP measures the latency of all user interactions (clicks, taps, key presses) to assess overall page responsiveness, replacing FID as a Core Web Vital.
Question 5: What is the purpose of a 'breadcrumb' structured data markup?
- To help search engines understand internal linking patterns
- To enable rich result breadcrumb trails in SERPs and clarify site hierarchy (Correct answer)
- To speed up crawling of category pages
- To define the canonical path for paginated content
Correct answer: To enable rich result breadcrumb trails in SERPs and clarify site hierarchy
Breadcrumb schema helps Google display a page's position in the site hierarchy in search results, improving click-through rates.
Question 6: When should you use pagination rel='next' and rel='prev' link attributes?
- On AMP pages to link to their canonical counterparts
- To signal a series of sequentially paginated pages to search engines (Correct answer)
- To indicate next and previous blog posts by date
- To set the crawl order for category pages
Correct answer: To signal a series of sequentially paginated pages to search engines
Rel=next and rel=prev help search engines understand paginated content series, though Google has deprecated their support; canonical is now preferred.
Question 7: What does 'lazy loading' of images do from an SEO perspective if implemented incorrectly?
- It increases LCP by deferring all images indefinitely
- It can hide important images from Googlebot if JavaScript rendering fails (Correct answer)
- It prevents images from appearing in Google Image Search
- It causes duplicate image indexing
Correct answer: It can hide important images from Googlebot if JavaScript rendering fails
If lazy loading relies on JavaScript that Googlebot doesn't execute properly, images may not be indexed or may negatively impact LCP scores.
