  1. A mobile website has a Cumulative Layout Shift (CLS) score of 0.28. How is this rated by Google's Core Web Vitals?

    Answer: Poor

    Google rates CLS above 0.25 as 'Poor'; a score of 0.28 falls in this range, meaning the page has significant unexpected layout shifts.

  2. What technique involves serving different HTML content to mobile and desktop users from the same URL based on the User-Agent string?

    Answer: Dynamic Serving

    Dynamic serving uses the User-Agent header to detect the device type and serve different HTML/CSS from the same URL, without a redirect.

  3. Which of the following is a disadvantage of using separate mobile URLs (e.g., m.example.com) compared to responsive design?

    Answer: They require maintaining two separate codebases and content sets

    Separate mobile sites require duplicating content, development, and maintenance efforts across two codebases, increasing cost and complexity.

  4. On mobile landing pages, above-the-fold content refers to content that is visible:

    Answer: Without any scrolling on the initial screen view

    Above-the-fold content is what users see immediately upon landing without scrolling, making it critical for first impressions and CTA visibility.

  5. What does minifying CSS and JavaScript files accomplish for mobile web performance?

    Answer: Reduces file size by stripping whitespace, comments, and shortening variable names

    Minification removes unnecessary characters (whitespace, comments) from code without changing functionality, resulting in smaller files that download faster.

  6. A Progressive Web App (PWA) differs from a standard mobile website primarily because it can:

    Answer: Work offline and be installed on the home screen

    PWAs use service workers and web app manifests to enable offline functionality and home screen installation, blurring the line between web and native apps.

  7. When configuring Google Search Console, what signal should you use to verify that Googlebot can crawl your mobile pages correctly?

    Answer: URL Inspection Tool using the 'Mobile' rendering option

    The URL Inspection Tool in GSC shows how Googlebot renders a page, including mobile rendering via the smartphone Googlebot user agent.
