A
A/B Testing
A method of comparing two versions of a page or element to determine which performs better. One version is shown to half your visitors, the other to the other half — the winner gets shipped.
Above the Fold
The portion of a webpage visible without scrolling. What lives above the fold needs to earn attention immediately — if it doesn't hook someone in the first few seconds, they're gone.
Analytics
The collection and interpretation of data about how people interact with your site or product. Good analytics tell you what's happening; great analytics tell you why.
Attribution
The process of identifying which marketing touchpoints led to a conversion. Attribution is notoriously messy in multi-channel funnels — most models oversimplify reality.
B
B2B
Business-to-business — selling products or services to other companies rather than to consumers. B2B buying cycles are longer, involve more stakeholders, and reward trust-building over impulse.
Bottom of Funnel
The final stage of the buyer journey, where a prospect is close to making a decision. Bottom-of-funnel content — demos, case studies, pricing pages — needs to close, not educate.
Bounce Rate
The percentage of visitors who leave your site after viewing only one page. A high bounce rate often signals a disconnect between what brought visitors to the page and what they found when they got there.
Brand Awareness
The degree to which your target audience recognises and recalls your brand. It's a long game — awareness doesn't convert immediately, but it lowers the cost of every future touchpoint.
C
Call to Action (CTA)
A prompt that tells a visitor what to do next — "Book a demo," "Start free trial," "Get a quote." A weak CTA is one of the fastest ways to kill an otherwise solid page.
Churn Rate
The percentage of customers who cancel or don't renew within a given period. In SaaS, churn is the silent revenue killer — even a 1% monthly reduction compounds massively over time.
Click-Through Rate (CTR)
The percentage of people who click a link, ad, or button out of everyone who saw it. CTR measures interest, not intent — a high CTR means the hook worked, not that the product fits.
Conversion Rate
The percentage of visitors who complete a desired action — signing up, purchasing, booking a call. Conversion rate is the single most important metric on any page with a goal.
CRO
Conversion Rate Optimisation — the systematic process of increasing the percentage of visitors who take a desired action. Good CRO is built on evidence, not gut feel.
Customer Acquisition Cost (CAC)
The total cost to acquire a single new customer, including marketing and sales spend. CAC only makes sense relative to LTV — a high CAC is fine if the lifetime value justifies it.
D
Dark Pattern
A UI design trick that manipulates users into doing something they didn't intend — like hiding the cancel button or pre-checking boxes. Short-term wins, long-term brand damage.
Demo Request
A conversion goal where a prospect asks to see your product in action. Demo requests are high-intent signals — they sit near the bottom of the funnel and have a short sales cycle.
Drip Campaign
A sequence of automated emails sent over time, triggered by a user action or schedule. Drip campaigns nurture leads gradually rather than pitching once and hoping for the best.
E
Evergreen Content
Content that stays relevant and valuable long after it's published — guides, definitions, how-tos. Evergreen content compounds in SEO value in a way that trend pieces never can.
Exit Intent
A trigger that detects when a user is about to leave a page and displays a targeted message or offer. Used correctly it recovers conversions; used badly it just annoys people.
F
First-Party Data
Data you collect directly from your own customers and visitors — form submissions, purchase history, on-site behaviour. First-party data is the most reliable and increasingly the most valuable kind.
Funnel
A model that maps the stages a prospect moves through from first awareness to becoming a customer. In practice, funnels are messy and non-linear — but the model is still useful for spotting drop-off.
G
Gated Content
Content that requires a visitor to provide their email or other information before accessing it — ebooks, whitepapers, reports. Gating works when the perceived value exceeds the friction.
Growth Hacking
An experimentation-driven approach to finding scalable, often unconventional ways to grow a user base quickly. The term is overused — at its core, it just means running fast, data-informed experiments.
H
Heatmap
A visual tool that shows where users click, scroll, and hover on a page. Heatmaps reveal what's getting attention and what's being ignored — often in ways that analytics alone can't show.
Hero Section
The top section of a webpage, typically containing the primary headline, subtext, and CTA. The hero has one job: convince someone to keep scrolling.
I
Impression
A single instance of an ad, listing, or piece of content being displayed to a user. Impressions measure reach, not engagement — a million impressions with zero clicks means the creative or targeting is off.
Inbound Marketing
A strategy focused on attracting customers through content, SEO, and value rather than interrupting them with ads. Inbound scales slowly but builds durable, compounding growth.
Intent Signal
A behavioural indicator that a prospect is actively researching or ready to buy — visiting a pricing page, requesting a demo, searching for competitor alternatives. Intent signals prioritise your outreach.
J
Journey Map
A visual representation of every touchpoint a customer has with your brand from first awareness to post-purchase. Journey mapping surfaces friction and gaps that individual metrics miss.
K
KPI (Key Performance Indicator)
A measurable value that indicates how effectively a goal is being achieved. KPIs are only useful if they're tied to outcomes — tracking vanity metrics as KPIs is one of the most common mistakes in marketing.
L
Landing Page
A standalone page designed to receive traffic from a specific campaign and drive a single conversion. A landing page with two goals is a landing page with no goals.
Lead Generation
The process of attracting potential customers and capturing their contact information for follow-up. Lead gen quality matters more than quantity — a smaller list of real prospects beats a bloated one.
LTV (Lifetime Value)
The total revenue you can expect from a single customer over the entire relationship. LTV is the metric that justifies your CAC — and the one most early-stage companies underestimate.
M
Meta Description
The snippet of text shown below a page title in search results. Meta descriptions don't directly affect rankings, but a well-written one meaningfully improves click-through rate.
Middle of Funnel
The consideration stage, where a prospect knows they have a problem and is evaluating solutions. Middle-of-funnel content — comparisons, case studies, webinars — builds credibility and moves intent forward.
MQL (Marketing Qualified Lead)
A lead that marketing has assessed as likely to become a customer based on engagement criteria. The MQL definition is everything — a poorly defined MQL wastes sales time and creates internal friction.
N
Net Promoter Score (NPS)
A metric that measures customer loyalty by asking how likely they are to recommend you on a 0–10 scale. NPS is a lagging indicator — by the time it drops, the problem has already been brewing.
North Star Metric
The single metric that best captures the core value your product delivers to customers. A good North Star aligns the whole company — a bad one optimises the wrong thing and erodes the product.
O
OKR (Objective and Key Result)
A goal-setting framework that pairs a qualitative objective with measurable key results. OKRs work when they're ambitious and honestly graded — they fail when they become a checkbox exercise.
Organic Traffic
Visitors who arrive via unpaid channels — primarily search engines. Organic traffic is slow to build but cheap to keep, which is why it's the highest-ROI channel for most SaaS companies over a 12-month horizon.
P
Pain Point
A specific problem or friction that a potential customer is experiencing. Speaking directly to pain points in your messaging is almost always more effective than leading with features.
Persona
A semi-fictional representation of your ideal customer based on real data and research. Personas are only useful if they're grounded in actual interviews — made-up personas produce made-up marketing.
Positioning
How you define your product's place in the market relative to alternatives. Positioning is the strategic layer under all your messaging — get it wrong and no amount of good copy will fix it.
Product-Led Growth (PLG)
A go-to-market strategy where the product itself is the primary driver of acquisition, retention, and expansion. PLG works when the product delivers value quickly and has a natural sharing or upgrade mechanic.
Q
Qualified Lead
A prospect who has been evaluated and meets specific criteria that suggest they're a genuine fit for your product or service. Volume of leads is meaningless without a qualification layer.
R
Retention Rate
The percentage of customers who continue using your product over a given period. Retention is the foundation of compounding growth — acquisition gets people in the door; retention keeps the business alive.
Revenue Attribution
The practice of connecting revenue back to the specific marketing activities that generated it. Accurate attribution is hard — but even an imperfect model beats allocating budget with no data at all.
S
SaaS
Software as a Service — a software distribution model where applications are hosted in the cloud and accessed via subscription. SaaS companies live and die by retention, not just acquisition.
SEO
Search Engine Optimisation — the practice of improving a site's visibility in organic search results. SEO combines technical health, content quality, and link authority — neglect any one of the three and results stall.
SERP
Search Engine Results Page — the page displayed by a search engine in response to a query. Ranking on page one of the SERP is the difference between being found and being invisible.
Social Proof
Evidence that others have found value in your product — testimonials, reviews, case studies, logos. Social proof works because people trust what other people have already validated.
SQL (Sales Qualified Lead)
A lead that the sales team has reviewed and determined is worth pursuing. SQLs are further down the funnel than MQLs — they've shown enough intent that a direct conversation makes sense.
T
Top of Funnel
The awareness stage — where someone first discovers a problem or your brand. Top-of-funnel content educates broadly and captures attention without expecting immediate conversion.
Traffic Source
The channel through which a visitor arrived at your site — organic, paid, referral, direct, social, or email. Understanding traffic sources helps you double down on what's working and diagnose what isn't.
U
Upsell
Encouraging an existing customer to upgrade to a higher tier or add a premium feature. Upselling existing customers is typically three to five times cheaper than acquiring new ones.
UX (User Experience)
The overall experience a person has when interacting with your product or website — from first impression to task completion. Good UX removes friction; great UX makes the right path feel obvious.
V
Value Proposition
A clear statement of why someone should choose your product over alternatives — what you do, for whom, and why it matters. A vague value prop is the fastest way to lose a visitor in the first five seconds.
Viral Coefficient
A measure of how many new users each existing user generates. A viral coefficient above 1 means the product grows on its own — below 1, growth requires sustained external investment.
W
Wireframe
A low-fidelity visual blueprint of a page or screen that outlines structure and layout without final design. Wireframes make it cheap to challenge assumptions before anyone writes a line of code.
