Question 1: Which metric does Google use to measure the visual stability of a mobile page during loading?
- Cumulative Layout Shift (CLS) (Correct answer)
- First Input Delay (FID)
- Largest Contentful Paint (LCP)
- Time to First Byte (TTFB)
Correct answer: Cumulative Layout Shift (CLS)
CLS quantifies how much visible content unexpectedly shifts during page load, directly impacting mobile user experience.
Question 2: What is the primary purpose of implementing a responsive viewport meta tag on a mobile website?
- To control how the page scales and displays on different screen sizes (Correct answer)
- To improve server response time for mobile users
- To enable push notification functionality
- To reduce image file sizes automatically
Correct answer: To control how the page scales and displays on different screen sizes
The viewport meta tag instructs the browser on how to control the page's dimensions and scaling to fit the device screen.
Question 3: A mobile site loads its main hero image in 4.8 seconds; which Core Web Vital threshold does this fail?
- Largest Contentful Paint (LCP) should be under 2.5 seconds (Correct answer)
- First Input Delay (FID) should be under 100 milliseconds
- Cumulative Layout Shift (CLS) should be under 0.1
- Interaction to Next Paint (INP) should be under 200 milliseconds
Correct answer: Largest Contentful Paint (LCP) should be under 2.5 seconds
Google recommends LCP occur within 2.5 seconds, so a 4.8-second hero image load is a clear failure of that threshold.
Question 4: Which mobile SEO practice helps search engines discover and index JavaScript-rendered content more reliably?
- Server-side rendering or dynamic rendering (Correct answer)
- Adding more inline JavaScript
- Using client-side-only routing with hash fragments
- Disabling the robots.txt file entirely
Correct answer: Server-side rendering or dynamic rendering
Server-side rendering delivers fully rendered HTML to crawlers, eliminating dependency on JavaScript execution for indexing.
Question 5: What is the recommended approach when a mobile page has interactive elements like buttons that are too close together?
- Ensure tap targets are at least 48x48 CSS pixels with adequate spacing (Correct answer)
- Reduce font size so more content fits on screen
- Use hover states to differentiate clickable areas
- Replace buttons with text hyperlinks
Correct answer: Ensure tap targets are at least 48x48 CSS pixels with adequate spacing
Google recommends minimum 48x48 CSS pixel tap targets with sufficient spacing to prevent accidental taps on mobile devices.
Question 6: How does mobile page speed primarily affect organic search rankings since Google's Speed Update?
- Extremely slow pages may receive a ranking demotion compared to faster competitors (Correct answer)
- Faster pages always rank first regardless of content relevance
- Page speed only affects paid search ad placement, not organic results
- Speed is measured only on desktop and applied to mobile rankings
Correct answer: Extremely slow pages may receive a ranking demotion compared to faster competitors
Google's Speed Update uses mobile page speed as a ranking signal where very slow pages can be demoted, though relevance remains the primary factor.
