Question 1Digital marketing concepts

Which statement best describes digital marketing?

  1. Printing brochures and distributing them to households by post
  2. Selling goods only through physical retail outlets
  3. Recording customer purchases in an accounting system
  4. Promotion of goods and services through digital channels Correct answer.

Explanation

Digital marketing covers promotional activity delivered through electronic channels such as websites, search engines, email and social media. It is broader than any single channel and includes both paid and unpaid methods.

Question 2Digital marketing concepts

What is the main purpose of search engine optimisation (SEO)?

  1. To replace social media activity with email campaigns
  2. To improve a site's unpaid ranking in search results Correct answer.
  3. To increase paid advertising spend on search results
  4. To block search engine crawlers from visiting a site

Explanation

SEO is the practice of improving a website's content, structure and technical quality so it ranks higher in unpaid search results. It targets organic visibility rather than bought placements.

Question 3Digital marketing concepts

In pay-per-click (PPC) advertising, when does the advertiser normally pay?

  1. Only when a user clicks the advertisement Correct answer.
  2. Once a month regardless of the results achieved
  3. Only when a user completes a purchase
  4. Every time the advertisement is displayed to a user

Explanation

The pay-per-click model charges the advertiser each time a user clicks the advertisement. Displaying an ad without a click is generally free under this model.

Question 4Digital marketing concepts

What is a call to action (CTA)?

  1. A prompt asking the reader to take a specific action Correct answer.
  2. A list of keywords used for search advertising
  3. A summary of a company's annual results
  4. A legal statement about data protection

Explanation

A call to action is an instruction or button that tells the audience what to do next, such as signing up, downloading or buying. It is a core element of most campaign pages.

Question 5Digital marketing concepts

What is a landing page?

  1. A page that lists products with no promotional aim
  2. The page a visitor reaches after clicking an ad or link Correct answer.
  3. The final page shown at the end of a checkout
  4. The home page of a company's internal staff network

Explanation

A landing page is the destination a visitor arrives at after clicking a link, advertisement or search result. Marketers usually design it around a single goal or offer.

Question 6Digital marketing concepts

What does organic traffic refer to?

  1. Visitors from unpaid search results Correct answer.
  2. Visitors from paid advertisements
  3. Visitors from an offline trade event
  4. Visitors from addressed direct mail

Explanation

Organic traffic consists of visitors who arrive without the site paying for that specific visit, most often through unpaid search listings. It is distinct from paid or direct traffic.

Question 7Digital marketing concepts

What is a target audience?

  1. The group of consumers a campaign aims to reach Correct answer.
  2. The competitors trading in the same market
  3. All people who have ever used the internet
  4. The employees who run a marketing department

Explanation

A target audience is the defined group of people a campaign is intended to reach, chosen because they are likely to be interested in the offer. It is established through market and audience research.

Question 8Digital marketing concepts

Which email metric reports the proportion of recipients who clicked a link in a message?

  1. Bounce rate
  2. Click-through rate Correct answer.
  3. Open rate
  4. Unsubscribe rate

Explanation

Click-through rate compares the number of link clicks with the number of messages delivered or opened. It shows how many recipients were motivated to act.

Question 9Digital marketing concepts

Which sequence lists the typical stages of a marketing funnel in the correct order?

  1. Consideration, loyalty, conversion, awareness
  2. Awareness, consideration, conversion, loyalty Correct answer.
  3. Conversion, awareness, loyalty, consideration
  4. Loyalty, consideration, awareness, conversion

Explanation

A funnel normally begins with awareness, moves into consideration of the offer, then conversion, and finally retention or loyalty. Each stage narrows the group of people involved.

Question 10Digital marketing concepts

What is a buyer persona?

  1. A researched profile of a typical customer Correct answer.
  2. A report on the pricing of competitors
  3. A fictional name for a product range
  4. A discount offered to returning customers

Explanation

A buyer persona is a research-based profile describing the goals, behaviour and characteristics of a representative customer segment. It helps marketers tailor messages to real needs.

Question 11Digital marketing concepts

What does remarketing (retargeting) do?

  1. It shows ads to people who visited the site before Correct answer.
  2. It sends catalogues to customers who stopped buying
  3. It removes inactive names from an email list
  4. It rewrites pages so they rank higher in search

Explanation

Remarketing uses cookies or identifiers to serve advertising to users who have already interacted with a site or app. It aims to bring those users back to complete an action.

Question 12Digital marketing concepts

An advertisement receives 400 impressions and 20 clicks. What is its click-through rate?

  1. 0.5%
  2. 2%
  3. 20%
  4. 5% Correct answer.

Explanation

Click-through rate equals clicks divided by impressions, multiplied by 100. Here 20 divided by 400 equals 0.05, which is 5%.

Question 13Digital marketing concepts

A website received 2,000 visits and recorded 50 purchases in a month. What is the conversion rate?

  1. 4%
  2. 0.25%
  3. 25%
  4. 2.5% Correct answer.

Explanation

Conversion rate is the number of conversions divided by the number of visits, multiplied by 100. Here 50 divided by 2,000 equals 0.025, or 2.5%.

Question 14Digital marketing concepts

A very high bounce rate on a landing page most likely indicates that...

  1. the page loads unusually quickly
  2. the page attracts many returning visitors
  3. many visitors leave after viewing only that page Correct answer.
  4. the page contains a working contact form

Explanation

Bounce rate measures the share of sessions in which visitors leave without interacting further. A high value suggests the page did not meet expectations or offer a clear next step.

Question 15Digital marketing concepts

A customer posts a positive review of a product on a social network. This is an example of...

  1. earned media Correct answer.
  2. owned media
  3. paid media
  4. direct media

Explanation

Earned media is publicity the brand did not pay for or control, such as reviews, shares and word of mouth. It is generated by customers and supporters rather than bought.

Question 16Digital marketing concepts

What is the purpose of an A/B test?

  1. To compare the performance of two staff members
  2. To compare two page versions to see which performs better Correct answer.
  3. To split a budget equally between two agencies
  4. To check whether a site works on different browsers

Explanation

An A/B test exposes otherwise similar audiences to two variants and compares a defined metric. The variant with the stronger measured result can then be adopted.

Question 17Digital marketing concepts

In affiliate marketing, how is the affiliate usually rewarded?

  1. A share of the advertiser's annual profits
  2. A fixed fee paid before the campaign begins
  3. A commission for each sale or lead from its link Correct answer.
  4. Payment only when its own website is visited

Explanation

Affiliates are typically paid on a performance basis, earning a commission when a tracked link produces a sale or a qualifying lead. This aligns their reward with results.

Question 18Digital marketing concepts

What is the primary aim of content marketing?

  1. To attract and keep an audience with useful content Correct answer.
  2. To increase the number of pages on a website
  3. To hide product information from competitors
  4. To replace all paid advertising with press releases

Explanation

Content marketing publishes valuable, relevant material so that an audience chooses to engage with the brand over time. The aim is to build trust and interest rather than to interrupt people with ads.

Question 19Digital marketing concepts

What is a lead magnet?

  1. A pop-up that blocks visitors from leaving
  2. A free item offered in return for contact details Correct answer.
  3. A discount given only to existing customers
  4. A tool that counts website visitors

Explanation

A lead magnet is something of value, such as a guide or trial, offered in exchange for a visitor's contact information. It converts anonymous visitors into identifiable leads.

Question 20Digital marketing concepts

A campaign costs 500 and generates 2,000 in revenue. What is the return on ad spend (ROAS)?

  1. 4:1 Correct answer.
  2. 1:4
  3. 2:1
  4. 25%

Explanation

ROAS compares revenue with advertising cost, here 2,000 divided by 500. The result is 4, meaning four units of revenue for every unit spent.

Question 21Digital marketing concepts

A campaign delivers a large volume of visitors to a landing page, but very few complete the sign-up form. Which action best addresses the most likely cause?

  1. Review the page message and form length to reduce friction Correct answer.
  2. Increase the advertising budget to attract even more visitors
  3. Add more keywords to the paid search account
  4. Change the campaign objective to brand awareness

Explanation

When traffic is plentiful but conversions are scarce, the constraint usually lies at the page rather than at the top of the funnel. Reducing friction and improving message relevance directly targets the drop-off point.

Question 22Digital marketing concepts

An analyst measures every conversion using a last-click attribution model. What limitation should be considered?

  1. It credits only the final touchpoint and ignores earlier ones Correct answer.
  2. It cannot be applied to e-commerce websites
  3. It overstates the value of the first touchpoint in the journey
  4. It requires offline sales data in order to be accurate

Explanation

Last-click attribution assigns full credit to the final interaction before conversion. Channels that introduced or nurtured the customer earlier receive no credit, which can distort budget decisions.

Question 23Digital marketing concepts

A company wants to raise awareness of a new brand among a broad audience. Which KPI is most appropriate?

  1. Cost per acquisition
  2. Reach and impressions Correct answer.
  3. Average order value
  4. Cart abandonment rate

Explanation

Awareness objectives are measured by how many people see the message, so reach and impressions align with the goal. Acquisition and revenue metrics measure later funnel stages.

Question 24Digital marketing concepts

A company collects email addresses through an online form in a region where prior consent is required. Which practice best supports compliance?

  1. Requiring recipients to confirm their subscription by email Correct answer.
  2. Buying a list of addresses from a data broker
  3. Using pre-ticked consent boxes on the form
  4. Adding the address to the list immediately without any confirmation

Explanation

Where prior consent is required, a confirmation step proves the address owner actively agreed to receive messages. This is commonly implemented as a double opt-in process.

Question 25Digital marketing concepts

An A/B test shows version A converting at 3.1% and version B at 3.3% after only 200 visits each. What is the most reasonable conclusion?

  1. The sample is too small to draw a reliable conclusion Correct answer.
  2. The test proves that design has no effect on conversion
  3. Version B is definitely better and should be rolled out at once
  4. Version A should be discarded because it has the lower rate

Explanation

A small difference observed on a small sample can easily arise from random variation. The test should continue or be repeated until the result is statistically reliable before any rollout decision.

Question 26Digital marketing concepts

In pay-per-click (PPC) advertising, what does the advertiser pay for?

  1. Each time the advertisement is displayed to a user
  2. Each time a user clicks on the advertisement Correct answer.
  3. Each time a user completes a purchase after clicking
  4. A fixed monthly fee regardless of performance

Explanation

The pricing model is defined by the billing event: in PPC the charge is triggered by a click on the ad. Displaying an ad is the basis of CPM pricing, and completed sales are the basis of pay-per-sale or CPA arrangements.

Question 27Digital marketing concepts

What is the function of a call to action (CTA) in digital marketing?

  1. To measure how many visitors leave a page quickly
  2. To prompt the audience to take a specific next step Correct answer.
  3. To describe the company's history and values
  4. To set different prices for customer segments

Explanation

A CTA is a prompt, usually a button, link or line of copy, that asks the audience to perform one defined action such as buying, subscribing or downloading. Its purpose is to convert attention into a measurable response.

Question 28Digital marketing concepts

In digital marketing, what is a channel?

  1. A route through which marketing messages reach an audience Correct answer.
  2. The total budget assigned to a campaign
  3. The device on which a consumer views content
  4. The creative format used for a single advertisement

Explanation

A channel is the medium or route used to deliver messages, such as search, email, social media or display. Budgets, creative formats and devices are campaign inputs or contexts, not the delivery route itself.

Question 29Digital marketing concepts

A retailer writes an article on its own blog, pays for a sponsored social post, and a customer shares the article with friends. How should these three items be classified?

  1. Paid, owned and earned respectively
  2. Owned, paid and earned respectively Correct answer.
  3. Owned, earned and paid respectively
  4. Earned, paid and owned respectively

Explanation

Media are classified by who controls them: assets the brand controls are owned, space the brand pays for is paid, and publicity generated by others is earned. The blog is controlled by the retailer, the sponsored post is bought, and the customer share is third-party publicity.

Question 30Digital marketing concepts

What does programmatic advertising primarily automate?

  1. The recruitment of influencers for brand campaigns
  2. The design of a brand's logo and visual identity
  3. The writing of advertising copy by editorial teams
  4. The buying and placement of advertising space using software Correct answer.

Explanation

Programmatic buying uses software and auction rules to purchase and place ad impressions automatically, often in real time and targeted to specific audiences. Creative work and brand identity remain human-driven activities.

Question 31Digital marketing concepts

A campaign costs 1,200 in total and generates 40 new customers. What is the cost per acquisition?

  1. 48
  2. 30 Correct answer.
  3. 0.03
  4. 300

Explanation

Cost per acquisition divides total campaign cost by the number of acquisitions: 1,200 divided by 40 equals 30. The metric expresses what the business spent to gain each new customer.

Question 32Digital marketing concepts

An online advert is displayed 5,000 times in a week to 2,000 different people. Which statement is correct?

  1. Reach is 5,000 and impressions are 2,000
  2. Reach is 2,000 and impressions are 7,000
  3. Reach and impressions are both 5,000
  4. Reach is 2,000 and frequency is 2.5 Correct answer.

Explanation

Impressions count every display (5,000), while reach counts the unique people exposed (2,000). Average frequency is impressions divided by reach, giving 2.5 exposures per person.

Question 33Digital marketing concepts

A brand wants to establish whether its display campaign caused extra sales, rather than reaching people who would have bought anyway. Which approach is most suitable?

  1. Ask customers in a survey whether they remember seeing the ad
  2. Attribute each sale to the last advertisement the customer clicked
  3. Compare a randomly held-out group with an exposed group Correct answer.
  4. Increase the campaign budget and observe whether total sales rise

Explanation

Causal lift is measured by comparing outcomes for a randomly selected group that received the campaign with a control group that was deliberately withheld. Random assignment isolates the campaign's effect from factors such as seasonality or existing buying intent.

Question 34Digital marketing concepts

After moving budget to cheaper placements, a marketer finds that cost per click has fallen, but conversion rate and revenue per visitor have also fallen. What is the most reasonable conclusion?

  1. Cost per click alone is not a measure of efficiency Correct answer.
  2. Revenue per visitor is irrelevant when clicks are cheap
  3. The conversion rate must be reported incorrectly
  4. The campaign is more efficient because clicks now cost less

Explanation

Cheap clicks are only valuable if they lead to profitable outcomes, so efficiency should be judged on cost per acquisition and revenue relative to spend. A lower cost per click alongside weaker conversion and revenue per visitor can mean total performance has worsened.

Question 35Web presence

What is the main purpose of a domain name?

  1. To provide a memorable address for a website Correct answer.
  2. To describe how a page should be displayed on screen
  3. To store the files that make up the web pages
  4. To encrypt data sent between a browser and a server

Explanation

A domain name is the human-readable address typed into a browser to reach a site, such as example.com. It is mapped to a numeric IP address by the domain name system. Storing files is the job of a host and encryption is handled by a security certificate.

Question 36Web presence

In the address https://www.example.com/shop/shoes, which part is the protocol?

  1. https Correct answer.
  2. /shop/shoes
  3. www.example.com
  4. example.com

Explanation

A URL begins with the protocol, which tells the browser how to communicate with the server. In this address https is the protocol, followed by the host name and then the path. The remaining parts identify the server and the location of the page on it.

Question 37Web presence

Which page normally acts as the entry point of a website and introduces the organisation?

  1. The home page Correct answer.
  2. The terms and conditions page
  3. The 404 error page
  4. The sitemap page

Explanation

The home page is the default page served when a visitor requests the root address of a site. It usually introduces the organisation and directs visitors to the main sections. Error pages and legal pages serve supporting roles rather than acting as the entry point.

Question 38Web presence

A website that automatically adjusts its layout to suit phones, tablets and desktop screens is described as what?

  1. Dynamic
  2. Static
  3. Responsive Correct answer.
  4. Optimised for search

Explanation

Responsive design uses flexible grids, fluid images and media queries so that one set of pages adapts to any screen size. This removes the need to maintain separate mobile and desktop versions of a site. Static and dynamic describe how content is generated, not how layout adapts.

Question 39Web presence

What does the 's' in HTTPS indicate compared with HTTP?

  1. The connection is encrypted Correct answer.
  2. The site is hosted in a secure server room
  3. The site has been checked by a government body
  4. The page loads faster

Explanation

HTTPS runs HTTP over an encrypted TLS connection, so data exchanged between browser and server cannot easily be read or altered in transit. Browsers mark such sites as secure. The presence of HTTPS says nothing about the physical location of servers or about speed.

Question 40Web presence

What is a hyperlink?

  1. A clickable element that opens another page Correct answer.
  2. A small icon shown in the browser tab
  3. A list of pages indexed by a search engine
  4. A file that stores the colour and font rules of a site

Explanation

A hyperlink is text or an image that, when selected, takes the user to another page, another part of the same page, or a file. It is defined in HTML with an anchor element and a target address. Styling files and indexing lists are different concepts.

Question 41Web presence

What is the role of a web hosting service?

  1. To translate page content automatically for foreign visitors
  2. To design the visual layout of the individual web pages
  3. To store website files and make them available online Correct answer.
  4. To register a domain name and manage its yearly renewal

Explanation

A host provides server space and connectivity so that stored files can be requested by visitors around the clock. The domain name points to that server through DNS records. Design, translation and domain registration are separate services.

Question 42Web presence

What is the main function of a content management system (CMS)?

  1. To let non-technical staff create and edit web pages Correct answer.
  2. To measure the number of visitors to a site
  3. To compress images before they are uploaded
  4. To check a site for broken links

Explanation

A CMS separates content from presentation so that authors can add, edit and publish pages through a browser interface without writing code. Templates then apply the design consistently to all content. Analytics, image optimisation and link checking are separate tools.

Question 43Web presence

A company runs shop.example.com alongside www.example.com. What is 'shop' in this address?

  1. A directory
  2. A top-level domain
  3. A protocol
  4. A subdomain Correct answer.

Explanation

A subdomain is a prefix added to a registered domain to create a separate section or site, such as shop.example.com. It is configured through DNS records and can point to an entirely different server. The top-level domain here is .com.

Question 44Web presence

Why should meaningful alternative text be added to images on a website?

  1. It describes images to screen reader users and search engines Correct answer.
  2. It makes the images load more quickly on mobile devices
  3. It increases the maximum file size allowed for the image
  4. It prevents other sites from copying the images

Explanation

Alternative text conveys the content and function of an image when it cannot be seen, for example by users of screen readers or when an image fails to load. It also gives search engines context about the image. It has no effect on file size, speed or copying.

Question 45Web presence

What is the purpose of breadcrumb navigation on a website?

  1. To link the site to its social media profiles
  2. To list every page of the site in alphabetical order
  3. To display the most popular products to the visitor
  4. To show the visitor's location within the site hierarchy Correct answer.

Explanation

Breadcrumbs show the trail from the home page to the current page, so visitors understand where they are and can jump to a higher level. They are especially useful on large sites with deep category structures. They do not list all pages or promote products.

Question 46Web presence

Which statement about country-code top-level domains is correct?

  1. They cannot be used for commercial websites
  2. They are two-letter codes such as .uk and .de Correct answer.
  3. They always rank higher than generic domains
  4. They can only be registered by government agencies

Explanation

Country-code top-level domains are assigned to countries and territories and normally consist of two letters, for example .uk, .de or .jp. Registration rules vary, but businesses and individuals commonly use them. Search engines do not give them an automatic ranking advantage.

Question 47Web presence

A report shows that many visitors leave a site after viewing a single page. Which measure describes this?

  1. Conversion rate
  2. Open rate
  3. Bounce rate Correct answer.
  4. Click-through rate

Explanation

Bounce rate is the percentage of sessions in which a visitor leaves after viewing only one page without interacting further. A high value can indicate that the entry page does not meet visitor expectations. Conversion rate measures completed goals, not single-page exits.

Question 48Web presence

What does HTTP status code 404 indicate?

  1. The requested page could not be found Correct answer.
  2. The visitor is not authorised to view the page
  3. The page has moved permanently to a new address
  4. The server is overloaded and cannot respond

Explanation

A 404 response means the server was reached but no resource matches the requested address. Well-designed sites show a helpful custom 404 page with links back into the site. Permanent moves and permission problems use different status codes.

Question 49Web presence

Why do websites use a favicon?

  1. To give the site a recognisable icon in browser tabs Correct answer.
  2. To show a cookie consent banner on the first visit
  3. To reduce the size of the image files used on the page
  4. To improve the site's position in search engine results

Explanation

A favicon is a small brand icon displayed in browser tabs, bookmarks and shortcut lists, helping users identify the site among open tabs. It has no bearing on ranking, consent or file compression. It is a branding aid rather than an SEO tool.

Question 50Web presence

What does a mobile-first approach to web design mean?

  1. The design is created for desktop and then shrunk to fit phones
  2. The site is only made available to users of mobile apps
  3. The site is rebuilt with a separate address for each device type
  4. The design starts with the small-screen layout and scales up Correct answer.

Explanation

Mobile-first design begins with the smallest screen and the most essential content, then progressively enhances the layout for larger displays. This prioritises performance and clarity on the devices most visitors use. It does not require separate addresses or restrict access to app users.
