Web Traffic Technology & Digital Applications 5 — Questions and Answers
Question 1: What is 'Cumulative Layout Shift' (CLS) and why does it affect user experience?
- It measures unexpected layout shifts during page load, which cause users to misclick on moving elements (Correct answer)
- It tracks the total number of DOM changes made by JavaScript after page load
- It measures the cumulative download size of all page resources affecting render time
- It calculates how often page layout differs between mobile and desktop viewports
Correct answer: It measures unexpected layout shifts during page load, which cause users to misclick on moving elements
CLS quantifies visual instability by summing shift scores whenever page elements move unexpectedly, which frustrates users who click wrong targets.
Question 2: Which technique involves splitting a JavaScript bundle into smaller chunks that are loaded only when needed, reducing initial page load time?
- Code splitting (Correct answer)
- Tree shaking
- Minification
- Transpilation
Correct answer: Code splitting
Code splitting divides a JavaScript bundle into smaller chunks that are loaded on demand, so users only download the code needed for the current page.
Question 3: What does 'Domain Authority' (DA) measure in the context of web traffic and SEO?
- A third-party score predicting a website's likelihood of ranking in search engines, based on backlink profile (Correct answer)
- Google's official metric for measuring a site's trustworthiness and indexing priority
- The number of unique domains that link to a website in a given month
- A site's average position across all keywords it ranks for in search results
Correct answer: A third-party score predicting a website's likelihood of ranking in search engines, based on backlink profile
DA is a proprietary metric by Moz (scale 1–100) that predicts ranking potential based on the quantity and quality of inbound links; it is not a Google metric.
Question 4: In digital advertising, what is 'programmatic advertising' in terms of traffic monetization?
- Automated buying and selling of ad inventory in real time using algorithms and data-driven targeting (Correct answer)
- A manual process where publishers and advertisers negotiate ad placements directly
- Pre-scheduled ad campaigns that run on fixed placements without real-time bidding
- A method for verifying that ads are shown to human traffic, not bots
Correct answer: Automated buying and selling of ad inventory in real time using algorithms and data-driven targeting
Programmatic advertising uses automated platforms and real-time bidding (RTB) to purchase ad impressions targeting specific audiences at scale.
Question 5: What is the purpose of an XML sitemap in relation to web traffic and search engines?
- To provide search engines a structured list of URLs to crawl, helping ensure all important pages are discovered and indexed (Correct answer)
- To display a visual map of site navigation for human visitors
- To block search engines from crawling low-quality or duplicate pages
- To specify geographic targeting settings for international search traffic
Correct answer: To provide search engines a structured list of URLs to crawl, helping ensure all important pages are discovered and indexed
XML sitemaps list a site's URLs with optional metadata (priority, change frequency, last modified) so crawlers can efficiently discover and re-crawl content.
Question 6: What is 'link equity' (also called 'link juice') in SEO?
- The ranking authority passed from one page to another through hyperlinks (Correct answer)
- The total monetary value generated by affiliate links on a page
- The proportion of a page's backlinks that come from high-traffic domains
- The number of internal links pointing to a site's homepage
Correct answer: The ranking authority passed from one page to another through hyperlinks
Link equity refers to the SEO value transferred via hyperlinks; pages with many high-quality inbound links accumulate authority that can be passed to linked pages.
Question 7: What does 'page experience' signal, as defined by Google, primarily include?
- Core Web Vitals, mobile-friendliness, HTTPS security, and absence of intrusive interstitials (Correct answer)
- Average session duration, pages per session, and overall bounce rate
- Social shares, comments, and user-generated content quality signals
- Ad density, affiliate link count, and sponsored content disclosure compliance
Correct answer: Core Web Vitals, mobile-friendliness, HTTPS security, and absence of intrusive interstitials
Google's Page Experience signal combines technical UX metrics: Core Web Vitals (LCP, INP, CLS), mobile usability, HTTPS, and intrusive interstitial guidelines.
