Web Traffic Technology & Digital Applications 3 — Questions and Answers
Question 1: What is 'dark traffic' in web analytics?
- Traffic incorrectly categorized as Direct because referrer data was stripped (Correct answer)
- Visits from users browsing in incognito or private mode
- Bot traffic that bypasses standard analytics filters
- Traffic from the dark web or Tor network
Correct answer: Traffic incorrectly categorized as Direct because referrer data was stripped
Dark traffic refers to referral visits (often from social media apps or secure-to-HTTP redirects) where the referrer header is lost and sessions appear as Direct traffic.
Question 2: Which Core Web Vital metric measures the largest visible content element's load time, reflecting perceived page load speed?
- Largest Contentful Paint (LCP) (Correct answer)
- Cumulative Layout Shift (CLS)
- Interaction to Next Paint (INP)
- First Contentful Paint (FCP)
Correct answer: Largest Contentful Paint (LCP)
LCP measures when the largest image or text block in the viewport finishes rendering, serving as a proxy for when the main content is loaded.
Question 3: In the context of web traffic acquisition, what does 'UTM tagging' accomplish?
- It appends parameters to URLs so analytics tools can attribute traffic to specific campaigns and sources (Correct answer)
- It encrypts URL parameters to prevent competitors from reading campaign data
- It shortens URLs for use in social media posts
- It verifies that a URL is safe before a user clicks it
Correct answer: It appends parameters to URLs so analytics tools can attribute traffic to specific campaigns and sources
UTM parameters (utm_source, utm_medium, utm_campaign, etc.) are added to URLs so analytics platforms can accurately attribute and segment traffic by campaign.
Question 4: What is the role of robots.txt on a website?
- To instruct search engine crawlers which pages they are allowed or disallowed from crawling (Correct answer)
- To block automated bot traffic from accessing the site entirely
- To define the sitemap location for all search engines
- To set crawl rate limits for human visitors
Correct answer: To instruct search engine crawlers which pages they are allowed or disallowed from crawling
The robots.txt file tells compliant web crawlers which sections of a site to avoid, though it is a suggestion, not a security barrier.
Question 5: Which protocol improvement introduced multiplexing, allowing multiple requests to be sent over a single TCP connection simultaneously?
- HTTP/2 (Correct answer)
- HTTP/1.1
- WebRTC
- FTP over TLS
Correct answer: HTTP/2
HTTP/2 introduced multiplexing, which eliminates head-of-line blocking by allowing concurrent requests and responses over one connection.
Question 6: What is a 'pixel' in digital marketing, such as the Meta Pixel or Google tag?
- A snippet of JavaScript code placed on a website to track visitor behavior and conversions (Correct answer)
- A 1×1 transparent image embedded in emails to track opens
- A CSS element used to measure screen resolution for responsive design
- A browser extension that records user sessions for analytics replay
Correct answer: A snippet of JavaScript code placed on a website to track visitor behavior and conversions
Marketing pixels are JavaScript snippets that fire in a user's browser, sending behavioral data to ad platforms for conversion tracking and audience building.
Question 7: What does the 'noindex' meta tag directive tell search engines?
- Do not include this page in the search engine's index (Correct answer)
- Do not follow any links on this page
- Do not cache a copy of this page
- Do not display this page in image search results
Correct answer: Do not include this page in the search engine's index
The noindex directive instructs compliant search engines to exclude the page from their index, preventing it from appearing in search results.
