Fundamentals of Digital Marketing

Digital marketing is the promotion of products or services through digital channels (search engines, social media, email, mobile apps, websites), with the ability to precisely measure results. It involves analytics, personalization, multichannel communication, and continuous testing.

Digital advertising is a paid form of communication in the online environment. It includes text, image, video, and interactive formats. Ads can be contextual, targeted, programmatic, or native, aiming to attract, engage, or convert users.

A digital marketer is a specialist who plans, executes, and analyzes advertising campaigns in the digital space. They work with channels (Google, Meta, TikTok, email, SEO), analytics tools (GA4, Looker Studio), automation solutions (scripts, AI), and are responsible for achieving business goals through digital touchpoints.

Digital strategy is a structured plan for achieving marketing or business goals through digital channels. It includes audience analysis, channel selection, KPI definition, media planning, creative concept development, optimization, and reporting.

Online marketing is a synonym for digital marketing, with a stronger focus on a brand’s web presence, such as websites, blogs, paid search ads, SEO, and email campaigns. The term is often used more broadly to refer to any marketing activity conducted online.

AIDA is a classic marketing model that describes the stages of the customer journey: Attention, Interest, Desire, and Action. It illustrates how advertising should first capture attention, then spark interest, create desire, and finally drive action. AIDA is commonly used when structuring ads, landing pages, email campaigns, and sales scripts.

SMM (Social Media Marketing) is the promotion of a brand through social media by creating relevant content, launching paid ads, managing comments, collaborating with influencers, and analyzing engagement. It includes platforms like Facebook, Instagram, TikTok, LinkedIn, Twitter/X, and others.

SEO (Search Engine Optimization) is a set of technical, content-related, and off-site activities aimed at improving a website’s visibility in organic search results (primarily on Google). It involves keyword strategy, page load speed, user experience (UX), backlinks, and more.

SEM (Search Engine Marketing) refers to marketing within search engines, primarily through paid promotion (e.g., Google Ads or Bing Ads). SEM includes creating text ads, selecting keywords, managing bids, and optimizing campaigns to drive traffic from search engine results pages (SERPs).

PPC (Pay-Per-Click) is an online advertising model where advertisers pay each time a user clicks on their ad, rather than for ad impressions. It is most commonly used in search advertising (Google, Bing) and on social media platforms (Meta, LinkedIn). PPC campaigns are typically designed to drive traffic or generate leads.

A communication channel is a digital platform or environment through which a brand interacts with its audience, for example, email, social media, or search engines.

Content marketing is a strategy focused on creating, publishing, and distributing valuable, relevant content to attract, engage, and convert a target audience. It may include blogs, guides, videos, checklists, podcasts, and social media posts.

A sales funnel is a model that describes the stages a user goes through from first discovering a brand to making a purchase. It typically includes the stages: awareness → interest → consideration → conversion → repeat purchase. Each stage requires tailored communication and its own set of KPIs.

Customer journey refers to the complete cycle of a person’s interaction with a brand, from the initial touchpoint to post-purchase actions and repeat engagement.

Digital brand presence is the combined set of channels and platforms where a business interacts with its online audience, including websites, social media, ads, marketplaces, and search results.

Personalization is the adaptation of advertising, content, or user experience messages to match a specific user or segment. It can be based on behavior, location, interests, or purchase history, and is used to boost engagement and conversions.

Ad Formats

Display Ads are graphical or animated banners shown on websites, in apps, or video platforms via advertising networks like Google Display Network (GDN).

Native advertising is an ad format that visually matches the style and tone of the surrounding content, making it feel like a natural part of the website or feed.

Teaser ads are short, eye-catching messages with bold headlines and images designed to spark curiosity and encourage clicks. They are often used in teaser ad networks.

Responsive Search Ads are a type of ad in Google Ads where you can enter multiple headlines and description options, and the system automatically combines them to match the user’s specific search query.

Video ads are promotional videos shown before, during, or after other video content on platforms like YouTube, Facebook, Instagram, or TikTok.

TrueView (YouTube) is a video ad format that allows users to skip the ad after 5 seconds. Advertisers are charged only if the viewer watches 30 seconds or more, or interacts with the ad.

ThruPlay (Meta) is a video ad delivery method on Facebook and Instagram that counts views when the video is watched to the end (if it’s 15 seconds or less) or for at least 15 seconds (if longer).

In-stream ads are video ads embedded directly into video content — before, during, or after — often with a skip option.

Out-stream ads are video formats displayed outside of video content, such as within news feeds or between paragraphs of articles, typically in mobile apps or on publisher websites.

Carousel Ads are a format that allows multiple images or videos to be shown in a single ad, with swipeable cards. This format is especially popular in Meta Ads.

Collection Ads are Meta ad formats that combine video or images with a product feed, opening a fast-loading instant storefront directly within Facebook or Instagram.

Instant Experience (formerly Canvas) is a full-screen Meta ad format that opens after a user taps on an ad, combining video, text, buttons, and carousels for an immersive mobile experience.

Metrics & KPIs

KPI (Key Performance Indicator) is a core performance metric used to evaluate the success of a campaign, strategy, or specific marketing action. KPIs are defined in advance based on business goals — for example, ROAS for revenue, CTR for engagement, or CPL for lead generation — and help objectively assess outcomes.

CPC (Cost Per Click) is the amount you pay for a single click on your ad. It’s a basic pricing model in search advertising. Formula: CPC = Total Spend ÷ Number of Clicks.

CPM (Cost Per Mille) refers to the cost of 1,000 ad impressions. It’s commonly used in display and video advertising to build brand awareness. Formula: CPM = (Spend ÷ Impressions) × 1,000.

CPA (Cost Per Action) is the cost you pay for a specific user action, such as a purchase, registration, or subscription. It’s a key metric in performance marketing. Formula: CPA = Total Spend ÷ Number of Conversions.

CPL (Cost Per Lead) is the cost of acquiring one lead (a potential customer). Formula: CPL = Total Spend ÷ Number of Leads.

CPO (Cost Per Order) is the cost of generating one completed order. It’s a key metric for e-commerce performance. Formula: CPO = Total Spend ÷ Number of Orders.

CPV (Cost Per View) is the cost of one video view. A view is typically counted after 30 seconds or if the user interacts with the video. Formula: CPV = Total Spend ÷ Number of Views.

VTR (View-Through Rate) shows the percentage of users who watched the video to the end or a defined point. Formula: VTR = (Completed Views ÷ Total Views) × 100%.

CTR (Click-Through Rate) measures how many users clicked on the ad after seeing it. Formula: CTR = (Clicks ÷ Impressions) × 100%.

CVR (Conversion Rate) indicates how many users who clicked on the ad completed a target action. Formula: CVR = (Conversions ÷ Clicks) × 100%.

Impression is a single instance of an ad being displayed to a user. It doesn’t necessarily mean the ad was viewed or interacted with.

Reach refers to the number of unique users who saw the ad at least once.

Frequency is the average number of times the same ad was shown to one user. Formula: Frequency = Impressions ÷ Reach.

Conversion is a target action completed by the user after viewing or interacting with an ad, such as making a purchase, subscribing, or filling out a form.

Micro conversion is an intermediate user action that moves them closer to the main conversion, such as watching a video, adding a product to the cart, or visiting the contact page.

Macro conversion is the primary goal of a campaign, for example, a purchase, registration, or subscription.

Lead Time is the amount of time between a user’s first interaction with a brand and the moment of conversion or purchase.

Bounce Rate is the percentage of users who leave a website without any interaction. In GA4, it has been replaced by the “engaged sessions” metric.

ROAS (Return on Ad Spend) measures the profitability of your ad spend, showing how much revenue you earn for every dollar (or hryvnia) invested in advertising. Formula: ROAS = Revenue ÷ Ad Spend.

ROI (Return on Investment) is the overall profitability of marketing or business investments, taking into account all costs. Formula: ROI = (Net Profit ÷ Total Costs) × 100%.

Cost per Result is the average cost of achieving a specific outcome in a campaign, such as a view, lead, or subscription.

Customer Acquisition Cost (CAC) represents the cost of acquiring one actual customer (not just a lead). Formula: CAC = Acquisition Spend ÷ Number of New Customers.

Lifetime Value (LTV) is the total revenue a customer is expected to generate over the entire duration of their relationship with a business.

ROMI (Return on Marketing Investment) is a variation of ROI that focuses solely on marketing spend. Formula: ROMI = (Revenue − Marketing Costs) ÷ Marketing Costs.

Engagement Rate measures how actively users interact with your content, calculated as the ratio of actions (likes, comments, clicks) to impressions or reach. Formula: Engagement Rate = (Engagements ÷ Reach or Impressions) × 100%.

Effective CPM (eCPM) is the effective cost per 1,000 impressions, taking into account all pricing models (CPC, CPA, etc.). Formula: eCPM = (Total Revenue ÷ Impressions) × 1,000.

eCPC (Effective Cost Per Click) is the actual average cost per click, factoring in all campaign costs and performance. Formula: eCPC = Total Spend ÷ Number of Clicks.

Conversion Window is the time frame after an ad click or view during which a conversion is still attributed to that interaction by the platform.

Analytics & Attribution

Analytics in digital marketing involves collecting, processing, and interpreting data about user behavior, ad performance, and conversion paths. It helps optimize campaigns, improve user experience, and make data-driven decisions.

Attribution in marketing is the process of identifying which channel or touchpoint contributed to a conversion. It allows marketers to allocate budgets more accurately across campaigns.

Last-click attribution is a model that gives full credit for the conversion to the last source a user interacted with before converting.

First-click attribution is a model that attributes 100% of the conversion value to the first channel that brought the user to the site.

Linear attribution is a model that evenly distributes credit for a conversion across all user touchpoints in the journey.

Time-decay attribution gives more credit to interactions that happened closer to the moment of conversion, with earlier touchpoints receiving less weight.

Position-based attribution (also known as U-shaped) assigns the most value to the first and last touchpoints, while distributing the remaining credit equally among the middle interactions.

Data-driven attribution uses machine learning to evaluate the impact of each channel on a conversion, based on actual user behavior and historical data.

Assisted Conversions are actions or touchpoints that contributed to a conversion but did not complete it. They help reveal which channels influenced the user’s decision along the journey.

Conversion tracking is the technology used to record user actions after clicking or viewing an ad — such as a purchase, form submission, or subscription — helping measure campaign effectiveness.

An event is a unit of user interaction (e.g., button click, download, scroll) used in GA4’s event-based tracking model to capture behavior beyond pageviews.

Engaged Session in GA4 is a session that lasted more than 10 seconds, had a conversion event, or included at least two page/screen views — a key indicator of user engagement.
