Digital marketing comes with plenty of terminology, from SEO and PPC to CTR, conversion rates, and social media metrics. If you are new to marketing, knowing what these terms actually mean can make campaign reports, strategy discussions, and performance data much easier to understand.
This glossary covers some of the most commonly used digital marketing terms and explains them in simple, practical language.
A
A/B Testing
A/B testing is the process of comparing two versions of a marketing asset to see which performs better. Marketers can test elements such as email subject lines, landing pages, headlines, CTAs, or ad creative and use the results to make better decisions.
Analytics
Analytics involves collecting and examining marketing data to understand what is happening across campaigns and channels. It can help marketers track website traffic, engagement, conversions, and other results to identify what is working and where improvements are needed.
C
Call to Action (CTA)
A CTA prompts an audience to take a specific action. Common examples include “Buy Now,” “Book a Consultation,” and “Download the Guide.” A good CTA makes the next step clear rather than leaving visitors wondering what to do.
Click-Through Rate (CTR)
CTR measures the percentage of people who click on a link or advertisement after seeing it. It is commonly used to assess the performance of search ads, social media campaigns, emails, and other clickable content.
Conversion
A conversion happens when someone completes an action that a business considers valuable. This could be buying a product, filling out a form, signing up for an email list, or booking a service.
Conversion Rate
Conversion rate shows how many visitors complete a desired action compared with the total number of visitors. It measures whether traffic is turning into meaningful results.
Cost Per Click (CPC)
CPC refers to the amount an advertiser pays for each click on a paid advertisement. It is commonly used in paid search and social advertising to understand how much it costs to generate traffic.
E
Engagement Rate
Engagement rate measures how actively people interact with content. Depending on the platform, engagement can include likes, comments, shares, saves, clicks, or other interactions. It helps marketers understand whether content is connecting with its audience.
I
Impressions
Impressions represent the number of times content or an advertisement is displayed. One person can generate multiple impressions if they see the same content more than once, so impressions are different from reach.
Influencer Marketing
Influencer marketing involves working with creators who have an established audience to promote a brand, product, or service. The approach can help businesses reach niche audiences and build trust through creator-led content.
K
Key Performance Indicator (KPI)
A KPI is a measurable value used to track progress towards a specific business or marketing goal. Depending on the campaign, KPIs might include leads, sales, conversion rate, website traffic, or customer acquisition cost.
P
Pay-Per-Click (PPC)
PPC is an advertising model in which businesses pay when someone clicks their advertisement. Search engines and social platforms commonly use this model, making it a popular way to generate targeted traffic.
R
Return on Investment (ROI)
ROI measures the value generated from an investment compared with its cost. In marketing, it helps businesses assess whether the money, time, and resources put into a campaign are producing worthwhile returns.
Reach
Reach refers to the number of unique people who see content or an advertisement. Unlike impressions, the same person is generally counted once within the specified reporting period.
S
Search Engine Optimisation (SEO)
SEO is the process of improving a website and its content to increase its visibility in organic search results. It can involve keyword research, content, technical improvements, website structure, and link building.
Search Engine Results Page (SERP)
A SERP is the page a search engine displays after someone enters a search query. It can contain organic listings, paid advertisements, featured snippets, images, videos, and other search features.
Social Media Marketing
Social media marketing involves using social platforms to promote a business, reach audiences, build relationships, generate leads, and support broader marketing goals. It can include organic content, paid advertising, community management, and performance analysis.
U
User-Generated Content (UGC)
UGC is content created by customers or other users, not directly by a brand. Common examples include reviews, customer photos, videos, and social media posts. Businesses can use this content to add authenticity and build trust.
