Marketing Glossary

Plain-language definitions, without the vendor spin.

A

A/B Testing: Showing two versions of the same page, email or ad to different visitors and keeping whichever one measurably performs better.
Attribution: Working out which marketing touchpoints actually caused a sale, so budget can follow what works rather than what's visible.

Bounce Rate: The share of visitors who leave after seeing a single page. High isn't automatically bad — it depends what the page was for.
Buyer Persona: A concrete sketch of a typical customer — their role, goals and objections — used to keep marketing aimed at a person instead of 'everyone'.

Content Calendar: The schedule of what gets published where and when. The difference between a content strategy and a pile of drafts.
Content Marketing: Earning attention by publishing genuinely useful material — articles, guides, tools — instead of buying attention with ads.
Conversion Rate: The percentage of visitors who do the thing you wanted — sign up, buy, book a call. The single most-watched number in most funnels.
CPC (Cost Per Click): What you pay an ad platform each time someone clicks your ad. The starting point, not the end, of judging whether an ad pays.
CTA (Call to Action): The prompt that tells a visitor what to do next — 'Start free', 'Book a demo'. Pages without one leak attention.
CTR (Click-Through Rate): Clicks divided by impressions: of everyone who saw the link or ad, how many clicked. A measure of relevance, not of revenue.
Customer Acquisition Cost: Everything you spend on marketing and sales to win one customer. Meaningful only next to what that customer is worth (LTV).
Customer Journey: The path a person takes from first hearing of you to buying and beyond — and everywhere along it that marketing can help or lose them.

Email Nurture: A planned sequence of emails that moves a lead from curious to ready, one useful message at a time, instead of one pitch and silence.
Engagement Rate: Interactions — likes, comments, shares, clicks — divided by how many people saw the content. Reach tells you size; engagement tells you interest.
Evergreen Content: Content that stays useful and keeps attracting search traffic for years, as opposed to news that expires in a week.

Impressions: How many times content was displayed, whether or not anyone acted on it. The top of every funnel and the easiest number to overvalue.

Keyword Research: Finding out what your audience actually types into search engines — the phrasing, the volume, the intent — before writing content to meet it.

Landing Page: A page built for one campaign and one action, with everything that doesn't serve that action removed.
Lead: A person who has shown real interest — left an email, booked a call, started a trial — and can now be marketed to directly.
Lead Magnet: Something valuable offered in exchange for contact details: a template, a report, a tool. The honest version is worth more than the gated fluff.
LTV (Lifetime Value): The total revenue a customer brings over the whole relationship. The ceiling on what you can afford to spend acquiring them.

Marketing Automation: Software carrying out repeatable marketing work — sending sequences, scoring leads, triggering follow-ups — so people can do the parts that need judgment.
Marketing Funnel: The path from stranger to customer, usually staged as awareness, consideration and decision. Fewer people at each stage — hence the shape.

Organic Traffic: Visitors who arrive from unpaid search results. Slow to build, cheap to keep, and the compounding asset most marketing underinvests in.

Positioning: The deliberate choice of what your product means, for whom, against which alternative — decided before any copy is written, or by default without you.

Retargeting: Showing ads to people who already visited you. Effective because interest was real; resented when it's overdone.
ROI (Return on Investment): What a marketing effort returned relative to what it cost. The question every other metric exists to eventually answer.

SEO (Search Engine Optimization): Making pages worth ranking and easy for search engines to understand, so people find you when they search for what you solve.
SERP: The search engine results page — the battlefield where rankings, snippets and ads compete for one click.

UTM Parameters: Tags added to a link's URL that tell your analytics exactly which campaign, channel and ad brought each visitor.
