Web Traffic Technology & Digital Applications 5

Question 1

What is 'Cumulative Layout Shift' (CLS) and why does it affect user experience?

Accepted Answer

It measures unexpected layout shifts during page load, which cause users to misclick on moving elements

Answer

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?

Accepted Answer

Code splitting

Answer

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?

Accepted Answer

A third-party score predicting a website's likelihood of ranking in search engines, based on backlink profile

Answer

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?

Accepted Answer

Automated buying and selling of ad inventory in real time using algorithms and data-driven targeting

Answer

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?

Accepted Answer

To provide search engines a structured list of URLs to crawl, helping ensure all important pages are discovered and indexed
