Marketing Report

A marketing report is a document that compiles performance data from one or more marketing channels over a set period, presenting metrics, trends, and analysis so teams can evaluate results and make decisions. Modern reports pair the numbers with written analysis that explains what changed and why.

Marketing Analytics

Marketing analytics is the practice of measuring, analyzing, and interpreting data from marketing activities to understand performance and improve results. It turns raw channel data into insights that guide budget, targeting, and optimization decisions.

Automated Reporting

Automated reporting is the use of software to generate marketing reports automatically by pulling data from connected channels, removing the need to export, format, and write reports by hand. It reduces reporting time from hours to minutes and keeps output consistent across periods.

Written Analysis

Written analysis is a plain-language explanation, generated alongside a report's metrics, that identifies which KPIs changed and the likely reason behind each change based on its degree of impact. It answers the 'why' behind the numbers rather than leaving readers to interpret charts.

Marketing Dashboard

A marketing dashboard is a visual interface that consolidates key metrics from one or more channels into charts and summaries for at-a-glance monitoring. Dashboards show current performance, while reports add period-over-period analysis and context.

KPI (Key Performance Indicator) alt: KPI

A key performance indicator (KPI) is a measurable value that shows how effectively a marketing activity is meeting a specific objective, such as cost per conversion or click-through rate. KPIs are chosen to reflect the goals that matter most to a campaign or business.

Metric

A metric is a single quantifiable measure of marketing activity, such as clicks, impressions, or sessions. Metrics become KPIs when they are tied directly to a goal used to judge success.

Benchmark

A benchmark is a reference point used to judge performance, such as a previous period's results, an industry average, or a set target. Comparing current metrics against a benchmark reveals whether performance is improving, declining, or holding steady.

Period-over-Period Analysis

Period-over-period analysis compares a metric across two consecutive time frames, such as this month versus last month, to measure change and identify trends. It is the basis for most performance reporting and for explaining why results moved.

Degree of Impact

Degree of impact is a measure of how much a specific factor contributed to an overall change in performance, used to rank the reasons behind a metric's movement. Prioritizing changes by degree of impact helps marketers focus on what mattered most.

Data Visualization

Data visualization is the presentation of data in visual formats such as charts, graphs, and tables to make patterns and comparisons easier to understand. In reporting, it turns rows of numbers into insights a reader can grasp at a glance.

Dimension

A dimension is a descriptive attribute used to break down and categorize metrics, such as device, country, campaign, or traffic source. Metrics are the numbers; dimensions are the labels you slice them by.

Segment

A segment is a subset of data isolated by shared characteristics, such as mobile users or visitors from a specific channel, so it can be analyzed on its own. Segmenting reveals patterns that overall totals hide.

Data Aggregation

Data aggregation is the process of combining data points into summary figures, such as totaling daily clicks into a monthly figure. It makes large datasets easier to report and compare.

Trend Analysis

Trend analysis is the examination of how metrics move over time to identify sustained increases, decreases, or seasonal patterns. It helps separate meaningful direction from short-term noise.

Data-Driven Decision Making

Data-driven decision making is the practice of basing marketing choices on measured evidence rather than intuition alone. It relies on accurate reporting and analysis to guide budget, targeting, and strategy.

Executive Summary

An executive summary is a brief, high-level overview at the start of a report that states the key results and takeaways before the detailed sections. It lets busy stakeholders grasp performance without reading every metric.

Insight

An insight is a meaningful, actionable conclusion drawn from data, going beyond what happened to explain why it matters and what to do next. Insights are the goal of analysis, not the raw metrics themselves.

Core Marketing Metrics 19 terms

Impressions

Impressions are the number of times an ad, listing, or piece of content was displayed, counted each time it appears on screen regardless of clicks. A high impression count indicates reach but does not by itself measure engagement.

Clicks

Clicks are the number of times users clicked on an ad, link, or listing. Clicks measure interest and are the numerator in click-through rate calculations.

Click-Through Rate (CTR) alt: CTR

Click-through rate (CTR) is the percentage of impressions that resulted in a click, calculated as clicks divided by impressions. It measures how compelling an ad or listing is at driving action relative to how often it was seen.

Conversion

A conversion is a completed action that a marketer defines as valuable, such as a purchase, sign-up, or form submission. Conversions connect marketing activity to business outcomes.

Conversion Rate

Conversion rate is the percentage of visitors or clicks that resulted in a conversion, calculated as conversions divided by the total visits or clicks. It measures how effectively traffic is turned into desired actions.

Cost Per Click (CPC) alt: CPC

Cost per click (CPC) is the average amount an advertiser pays each time someone clicks their ad, calculated as total spend divided by clicks. It is a core efficiency metric in paid search and paid social.

Cost Per Conversion alt: Cost Per Acquisition, CPA

Cost per conversion, also called cost per acquisition (CPA), is the average spend required to generate one conversion, calculated as total cost divided by the number of conversions. It shows how efficiently a campaign turns budget into results.

Return on Ad Spend (ROAS) alt: ROAS

Return on ad spend (ROAS) is the revenue generated for every unit of currency spent on advertising, calculated as revenue divided by ad spend. It measures the profitability of paid campaigns.

Reach

Reach is the number of unique people who saw a piece of content or an ad, as opposed to impressions, which count every view including repeats. Reach measures the size of the audience exposed to a message.

Engagement Rate

Engagement rate is the percentage of an audience that interacted with content through actions such as clicks, likes, comments, or shares. It measures how actively people respond to marketing rather than just how many saw it.

Spend

Spend is the total amount of money invested in advertising over a reporting period. It is the denominator for efficiency metrics such as CPC, CPA, and ROAS.

Frequency

Frequency is the average number of times each unique person saw an ad during a campaign, calculated as impressions divided by reach. High frequency can indicate overexposure and ad fatigue.

Cost Per Engagement (CPE) alt: CPE

Cost per engagement (CPE) is the average amount spent for each engagement with an ad, such as a like, comment, share, or interaction, calculated as spend divided by engagements. It measures the efficiency of engagement-focused campaigns.

Bounce

A bounce is a single-interaction visit where a user leaves a site without further engagement. In reporting, a high bounce count can signal a mismatch between visitor expectations and page content.

Average Order Value (AOV) alt: AOV

Average order value (AOV) is the average amount spent each time a customer places an order, calculated as total revenue divided by number of orders. Raising AOV is a common lever for growing revenue without more traffic.

Average Order Value (AOV) alt: CLV, LTV

Customer lifetime value (CLV) is the total revenue a business expects to earn from a customer over the entire relationship. It helps set how much can profitably be spent to acquire and retain each customer.

Churn Rate

Churn rate is the percentage of customers or subscribers who stop using a product or service during a period. It is a core retention metric, especially for subscription and SaaS businesses.

Return on Investment (ROI) alt: ROI

Return on investment (ROI) is a measure of profitability comparing the gain from an activity to its cost, expressed as a percentage or ratio. In marketing it shows whether the value generated exceeds what was spent.

Pageviews

Pageviews are the total number of times pages on a site were loaded or reloaded, counting every view including repeats by the same user. They measure content consumption volume rather than unique reach.

Google Analytics 4 (GA4) 16 terms

Google Analytics 4 (GA4) alt: GA4

Google Analytics 4 (GA4) is Google's web and app analytics platform built around an event-based data model, which replaced Universal Analytics in 2023. It measures user behavior across sessions, traffic sources, engagement, and conversions.

Session

A session is a group of user interactions with a website or app that take place within a given time frame. In GA4, a new session starts when a user engages after a period of inactivity.

Users

Users are the number of distinct individuals who visited a website or app in a reporting period, counted by unique identifiers rather than by visits. GA4 distinguishes between total users, active users, and new users.

Engaged Session

An engaged session in GA4 is a session that lasts longer than ten seconds, includes a conversion event, or has at least two page or screen views. It replaces the older bounce-based view of quality traffic.

Bounce Rate

Bounce rate is the percentage of sessions that were not engaged, meaning the visitor left without meaningful interaction. In GA4 it is defined as the inverse of engagement rate.

Event

An event in GA4 is any distinct user interaction that is measured, such as a page view, click, scroll, or purchase. GA4's entire data model is built on events rather than sessions and pageviews.

ABC Model (Acquisition, Behaviour, Conversion) alt: ABC Model

The ABC model is a framework for analyzing website performance across three stages: Acquisition (how users arrive), Behaviour (what they do on site), and Conversion (whether they complete a goal). It provides a structured way to read Google Analytics data.

Traffic Source

A traffic source is the origin from which a visitor arrived at a website, such as organic search, paid ads, referral, direct, or social. Analyzing traffic sources shows which channels drive the most valuable visitors.

Conversion Event

A conversion event in GA4 is an event marked as a key action, such as a purchase or sign-up, so it is counted as a conversion. Designating conversion events is how GA4 measures goal completions.

Engagement Rate (GA4)

Engagement rate in GA4 is the percentage of sessions that were engaged sessions. It replaced the older bounce-rate emphasis as GA4's primary measure of visit quality.

Landing Page

A landing page is the first page a visitor sees when arriving at a site from a link, ad, or search result. In analytics, landing-page reports show which entry points attract and convert traffic.

Exit Rate

Exit rate is the percentage of sessions that ended on a particular page, indicating where visitors most often leave. Unlike bounce rate, it counts exits regardless of whether the page was the only one viewed.

Average Engagement Time

Average engagement time in GA4 is the average length of time a site was in focus in a user's browser during a session. It measures active attention rather than passive open tabs.

Audience

An audience is a group of users grouped by shared attributes or behaviors, such as purchasers or cart abandoners, used for analysis and ad targeting. GA4 audiences can be exported to Google Ads for remarketing.

Universal Analytics alt: UA

Universal Analytics (UA) was the previous generation of Google Analytics, built on a session-and-pageview model, which stopped processing data in 2023. It was replaced by the event-based Google Analytics 4.

Google Tag Manager alt: GTM

Google Tag Manager (GTM) is a free tool for deploying and managing tracking tags and pixels on a website without editing code directly. It centralizes analytics and conversion tracking setup.

Attribution & Measurement 13 terms

Attribution

Attribution is the process of assigning credit for a conversion to the marketing touchpoints a user interacted with on the way to converting. It determines which channels and campaigns are recognized as driving results.

Attribution Model

An attribution model is a rule or set of rules that decides how conversion credit is distributed across touchpoints, such as last-click, first-click, or data-driven attribution. The chosen model shapes how channel performance is judged.

Multi-Channel Marketing

Multi-channel marketing is the practice of reaching audiences across several channels, such as search, social, and email, often measured together. Cross-channel reporting brings these channels into a single view to compare performance.

Cross-Channel Analytics

Cross-channel analytics is the analysis of marketing performance across multiple channels in one unified view, rather than in separate platform silos. It reveals how channels compare and contribute to overall results.

Conversion Tracking

Conversion tracking is the measurement of valuable actions users take after interacting with marketing, typically using tags or pixels. It links campaigns to outcomes and enables cost-per-conversion and ROAS reporting.

Last-Click Attribution

Last-click attribution assigns all credit for a conversion to the final touchpoint the user interacted with before converting. It is simple but undervalues earlier touchpoints in the journey.

First-Click Attribution

First-click attribution assigns all credit for a conversion to the first touchpoint in the user's journey. It highlights what introduced a customer but ignores later influences.

Data-Driven Attribution alt: DDA

Data-driven attribution distributes conversion credit across touchpoints based on their measured contribution, using a model rather than a fixed rule. It aims to reflect each channel's real influence on outcomes.

Customer Journey

The customer journey is the full sequence of interactions a person has with a brand across channels on the way to converting and beyond. Mapping it reveals which touchpoints influence decisions.

Touchpoint

A touchpoint is any single interaction between a customer and a brand, such as seeing an ad, clicking a link, or opening an email. Attribution models decide how much credit each touchpoint receives.

UTM Parameter

A UTM parameter is a tag added to a URL to record the source, medium, and campaign that brought a visitor to a site. UTMs let analytics tools attribute traffic and conversions to specific campaigns.

Marketing Funnel

The marketing funnel is a model of the stages a prospect passes through from awareness to consideration to conversion. It helps marketers align content and metrics to each stage of intent.

Incrementality

Incrementality is the measure of additional conversions that a marketing activity caused, beyond what would have happened anyway. It answers whether spend genuinely drove results rather than taking credit for existing demand.
