Marketing · Glossary

Every marketing term,
explained simply.

Plain-English definitions of the acronyms, metrics and jargon that get used around a small business without anyone stopping to explain them.

72 terms

A

  • A/B TestingStrategyRunning two versions of something — an email subject line, an ad, a landing page — against each other to see which performs better.

    The test is only worth running if you change one thing at a time and wait for enough traffic to tell the difference from noise. Most small-business A/B tests are called far too early.

  • AttributionAnalyticsDeciding which marketing touchpoint gets credit for a sale. If someone sees a reel, searches your name a week later, then books, attribution is how you decide what earned the booking.

    There is no correct answer, only models. Last-click attribution over-credits search, because search is usually the last step before someone who already decided takes action.

  • Average Order ValueAnalyticsTotal revenue divided by number of orders. It tells you what a typical customer spends in one transaction.

    Raising it is often cheaper than finding more customers, because the person is already buying. Bundles and a sensible upsell move it more than a discount does.

  • Awareness StageStrategyThe point where someone knows they have a problem but does not yet know the solutions, let alone your name.

    Content aimed here answers questions rather than selling. Pushing a booking link at someone in the awareness stage is the most common reason good content converts badly.

B

  • BacklinkSEOA link from another website to yours. Search engines read them as votes, so links from trusted, relevant sites lift your rankings.

    Relevance beats volume. One link from a respected site in your industry is worth more than fifty from directories nobody reads, and bought link packages tend to do damage.

  • Bounce RateAnalyticsThe share of visitors who land on a page and leave without doing anything else.

    A high bounce rate is not automatically bad. On a page that answers one question — opening hours, a phone number — someone leaving satisfied looks identical to someone leaving annoyed.

  • Brand VoiceContentThe consistent personality your writing has across every channel: the vocabulary, the sentence length, the things you refuse to say.

    It is defined more by exclusions than inclusions. Deciding you will never use exclamation marks or the word 'excited' does more for consistency than a page of adjectives.

  • Buyer PersonaStrategyA short profile of one type of customer: what they want, what they worry about, and what would make them choose someone else.

    Useful when built from real customer conversations, useless when invented in a meeting. If the persona has a stock photo and a name but no real quotes behind it, it will not change any decision.

C

  • Call to ActionContentThe specific thing you ask the reader to do next: book a call, get the guide, reply to this email.

    One per page, stated plainly. 'Learn more' asks for nothing and gets it; 'See the pricing' tells someone exactly what happens when they click.

  • Canonical URLSEOA tag that tells search engines which version of a page is the original, when the same content sits at more than one address.

    Matters most on e-commerce sites, where filters and sort orders generate dozens of URLs for one product. Without it, those versions compete with each other in search results.

  • Churn RateAnalyticsThe share of customers who cancel in a given period. For a subscription, it is the number that decides whether growth compounds or leaks.

    At five per cent monthly churn, the average customer stays twenty months. At ten per cent, ten. Halving churn does more for revenue than doubling ad spend.

  • Click-Through RatePaid adsClicks divided by impressions, as a percentage. It measures how compelling something is to the people who saw it.

    A high rate on the wrong audience costs money without producing customers. Read it next to conversion rate, never on its own.

  • Content CalendarContentA schedule of what gets published, where, and when — agreed in advance rather than decided the morning it goes out.

    The value is less in the planning than in removing the daily decision. Businesses that stop posting almost never decide to stop; they just run out of days where somebody chose a topic.

  • Conversion RateAnalyticsThe share of visitors who do the thing you wanted — bought, booked, subscribed, filled in the form.

    Always state what it converts from and to. A three per cent conversion rate means nothing until you know whether it is of all traffic, of ad clicks, or of people who reached the checkout.

  • Cost Per ClickPaid adsWhat you pay each time somebody clicks an ad. Set by auction, so it moves with competition and with how relevant the platform thinks your ad is.

    A cheap click is not a cheap customer. Legal and insurance keywords cost many times what most terms do precisely because the customers behind them are worth it.

  • Customer Acquisition CostAnalyticsEverything you spent on marketing and sales in a period, divided by the customers it won.

    It only means something beside lifetime value. Spending £300 to win a customer is reckless at a £200 lifetime value and a bargain at £3,000.

  • Customer Lifetime ValueAnalyticsThe total profit you expect from one customer across the whole relationship, not just their first purchase.

    Knowing it sets your ceiling on acquisition spend. Most small businesses underestimate it because they count the first sale and ignore repeat business and referrals.

D

  • Domain AuthoritySEOA third-party score, usually out of 100, predicting how well a site is likely to rank based on its link profile.

    Invented by SEO tools, not by Google, so treat it as a rough comparison between sites rather than a number to optimise. It is useful for judging whether a link is worth pursuing.

  • Drip CampaignEmailA fixed sequence of emails sent on a schedule after someone joins a list — day one, day three, day seven — regardless of what else they do.

    Simple to build and easy to leave running past its usefulness. Re-read a drip sequence once a year, because it will still be referring to last year's offer.

  • Dwell TimeSEOHow long someone stays on your page after clicking it in search results, before returning to the results.

    An immediate return suggests the page did not answer the question. Whether search engines measure it directly is debated; writing pages that hold attention is a good idea regardless.

E

  • Email AutomationEmailEmails triggered by behaviour rather than sent by hand: a welcome after signup, a reminder after an abandoned cart, a check-in after ninety days of silence.

    Usually the highest-return work in email, because the message arrives when the person is already thinking about you. A welcome sequence typically outperforms every newsletter you send.

  • Engagement RateSocialInteractions — likes, comments, shares, saves — as a share of the people who saw a post.

    Saves and shares are the signals worth watching. A like costs nothing; a share means somebody put their own name behind your content.

  • Evergreen ContentContentContent that stays accurate and useful long after it is published, as opposed to news, trends or seasonal posts.

    It compounds. A guide that answers a question customers ask every week will still bring traffic in three years, while a post about a platform update is dead in a month.

F

  • First-Party DataAnalyticsInformation you collected directly from your own customers — your email list, your purchase history, your site analytics.

    It became the valuable kind as tracking restrictions tightened. Anything that depends on third-party cookies has been degrading for years; an email list has not.

  • FunnelStrategyThe path from first hearing about you to buying, described in stages so you can see where people drop out.

    The metaphor is tidier than reality — people loop, leave and come back — but it earns its place by forcing the question of which stage is actually losing you money.

G

  • GeotargetingPaid adsRestricting who sees an ad based on where they are, from a country down to a radius around an address.

    For a business that serves one city, it is the single highest-return setting in the account. Check it monthly; platforms quietly widen targeting when a campaign struggles to spend.

  • Google Business ProfileSEOThe free listing that puts a business in Google Maps and in the local results box, with hours, photos, reviews and a phone number.

    For any business with a location or a service area, this outperforms most of what people spend on SEO. Complete it fully, post to it, and answer every review.

H

  • HashtagSocialA keyword prefixed with # that groups a post with others on the same topic and makes it findable by that topic.

    Their reach has fallen sharply as platforms moved to recommending content by interest instead. A handful of specific, relevant tags is now worth more than thirty broad ones.

  • Header TagSEOThe HTML headings that structure a page, from H1 down to H6. The H1 is the page's title; the rest break the content into sections.

    One H1 per page, describing what the page is about. Headings are how both a screen reader and a search engine work out the shape of an article without reading every word.

I

  • ImpressionsAnalyticsThe number of times something was displayed. Not the number of people who saw it, and not the number who noticed.

    The most inflatable number in marketing. Ten thousand impressions across two hundred people is a different story from ten thousand across ten thousand, and the headline figure hides which.

  • Inbound MarketingStrategyEarning attention with content people choose to read, rather than buying it by interrupting them.

    Slower to start and cheaper to sustain. The work compounds, which is why it suits businesses that can wait two quarters and badly suits those that need bookings this month.

  • Influencer MarketingSocialPaying someone with an established audience to feature your product to that audience.

    Audience fit beats audience size. A creator with 8,000 followers who all live in your city will usually outperform one with 400,000 scattered across the world.

J

  • Journey MappingStrategyWriting down every step a customer takes with you, including the ones that are not marketing — the phone call, the wait, the invoice.

    It tends to find the real problem. Plenty of businesses buy more traffic when what they have is a booking form that fails on mobile.

K

  • Keyword DifficultySEOAn estimate of how hard it would be to rank on the first page for a search term, based on who already ranks there.

    New sites should ignore high-difficulty terms entirely for the first year. Specific, lower-volume phrases convert better anyway, because the person searching them knows what they want.

  • Key Performance IndicatorAnalyticsThe small number of measures you have agreed actually indicate whether the work is succeeding.

    The discipline is in keeping the list short. A dashboard with thirty KPIs has none; nobody changes a decision because the twenty-second number moved.

L

  • Landing PageContentA page built for one campaign and one action, without the navigation and distractions of a normal site page.

    Sending ad traffic to a homepage is the most expensive habit in small-business advertising. The homepage has to serve everyone, so it persuades nobody in particular.

  • Lead MagnetEmailSomething useful offered in exchange for an email address — a guide, a checklist, a template, a discount code.

    It should solve a small, real problem in one sitting. A vague 'newsletter signup' converts a fraction as well as a specific thing someone can use today.

  • Lookalike AudiencePaid adsAn audience an ad platform builds by finding people who resemble a list you supplied, such as your existing customers.

    Quality depends entirely on the source list. Feed it your best customers rather than everyone who ever bought, or you teach the platform to find more of your worst.

M

  • Meta DescriptionSEOThe short summary shown under a page's title in search results. It does not affect rankings; it affects whether anyone clicks.

    Around 155 characters before it truncates. Write it as an advert for the page, not a summary of it, and include the phrase someone actually searched.

  • Micro-InfluencerSocialA creator with a small audience, typically between 1,000 and 50,000 followers, usually focused on one subject or place.

    Engagement rates run higher than on large accounts and the cost is a fraction. For local businesses this is where influencer spend generally works.

  • Monthly Recurring RevenueAnalyticsPredictable subscription revenue in a month, excluding one-off charges.

    Its usefulness is that it is boring. Stripping out one-off work shows whether the base of the business grew, which a headline revenue figure can easily hide.

N

  • Native AdvertisingPaid adsPaid content designed to match the form of the platform it appears on, so it reads like an article or a post rather than an advert.

    Disclosure is a legal requirement in most markets, not a courtesy. Undisclosed native advertising is the fastest way to lose an audience you paid to reach.

  • Negative KeywordPaid adsA term you tell an ad platform to exclude, so your ad never shows for searches containing it.

    Adding 'free', 'jobs', 'cheap' and 'DIY' cuts wasted spend in most new accounts. Review the search terms report monthly and keep adding.

  • Net Promoter ScoreAnalyticsA survey score from asking how likely someone is to recommend you, on a scale of nought to ten, then subtracting detractors from promoters.

    The number is less useful than the comment box under it. The reasons people give for a six are the roadmap; the score itself is a summary.

  • Nurture SequenceEmailA series of emails that keeps a lead who is not ready to buy in touch with you until they are.

    Most leads do not say no, they say not now. A sequence that stays useful for six months costs almost nothing and catches people at the point the timing changes.

O

  • Off-Page SEOSEOEverything that affects your search rankings from outside your own site: links, mentions, reviews and citations.

    Less controllable than on-page work and slower to move, which is why it is usually the part that has been neglected when rankings stall.

  • On-Page SEOSEOThe parts of ranking you control on the page itself: titles, headings, content, internal links, image attributes and page speed.

    Do this before chasing links. A site with thin content and duplicated titles will not rank however many links point at it.

  • Open RateEmailThe share of delivered emails that were opened. Measured with a tracking pixel, which is why it has become unreliable.

    Mail privacy features pre-open images automatically, inflating the figure. Click rate and replies now tell you far more about whether an email worked.

  • Organic ReachSocialHow many people saw your content without you paying to put it in front of them.

    It has declined on every major platform for a decade. Planning a strategy that assumes a fixed share of your followers will see a post is planning for 2014.

P

  • Pay-Per-ClickPaid adsAdvertising where you are charged when someone clicks, rather than when the ad is shown.

    Fast to turn on and fast to waste money with. Set conversion tracking before the first pound is spent, or you will be optimising for clicks you cannot value.

  • PixelPaid adsA snippet of code on your site that reports visitor actions back to an ad platform, so it can measure conversions and build audiences.

    Install it before you advertise, not when you start. It needs history to be useful, and an account with no conversion data optimises towards nothing.

  • Programmatic AdvertisingPaid adsBuying ad space automatically through real-time auctions, rather than negotiating placements with publishers.

    Efficient at scale and opaque at small budgets. For most small businesses the fees and the lack of visibility outweigh the reach.

Q

  • Qualified LeadStrategyA lead that matches who you actually sell to — right budget, right need, right authority to decide.

    Agreeing the definition between marketing and sales settles most arguments about lead quality before they start, because both sides are finally counting the same thing.

  • Quality ScorePaid adsGoogle Ads' rating of how relevant your keyword, ad and landing page are to each other, from one to ten.

    It directly changes what you pay. A high score can cut click costs by half against a competitor bidding the same amount with a mismatched landing page.

R

  • ReachSocialThe number of distinct people who saw your content, as opposed to impressions, which counts every time it appeared.

    Reach divided into impressions gives average frequency. When that climbs, you are showing the same thing to the same people rather than finding new ones.

  • RetargetingPaid adsShowing ads to people who already visited your site or engaged with your content.

    Usually the best-performing campaign in an account, and the easiest to overdo. Cap frequency and exclude people who already bought.

  • Return on Ad SpendPaid adsRevenue generated by advertising divided by what the advertising cost. A ROAS of 4 means £4 back for every £1 in.

    It is revenue, not profit. At a 25 per cent margin, a ROAS of 4 breaks even exactly, which is why a healthy-looking number can still be losing money.

  • Rich SnippetSEOA search result enhanced with extra detail — star ratings, prices, cooking times, FAQs — pulled from structured data on the page.

    Earned by adding schema markup, not by asking. They take up more space in the results and reliably lift click-through, even at the same ranking position.

S

  • Schema MarkupSEOStructured data added to a page's code that tells search engines exactly what things are: this is a price, this is a review, this is an opening time.

    The prerequisite for rich results. It is invisible to visitors, which is why it is so often missing from otherwise well-built sites.

  • Search Engine Results PageSEOThe page of results returned for a search, including ads, maps, featured snippets and the ordinary blue links.

    Ranking first no longer means being at the top. On many searches the first organic result sits below ads, a map pack and an answer box.

  • Share of VoiceStrategyYour share of the total market conversation or advertising in your category, against competitors.

    Useful as a relative measure over time. Falling share of voice while your own numbers hold steady means competitors are spending more, and it usually shows up in results a quarter later.

  • Social ProofContentEvidence that other people already chose you: reviews, testimonials, case studies, client logos, visible follower counts.

    Specific beats glowing. A review naming the problem and the result persuades far more than five stars and the word 'amazing'.

T

  • Target AudienceStrategyThe specific group your marketing is written for, defined tightly enough that you can say who it excludes.

    If you cannot name someone it is not for, it is not a target audience. Copy written for everyone reads as written by a committee.

  • Top of FunnelStrategyMarketing aimed at people who do not yet know they need you, measured by reach and attention rather than sales.

    Judging it by conversion rate kills it every time. It exists to fill the stages below, and its payoff shows up in searches for your name weeks later.

U

  • User-Generated ContentSocialPhotos, videos and reviews made by customers rather than by you or your agency.

    It outperforms polished production on most social platforms because it looks like the rest of the feed. Get written permission before reusing any of it in ads.

  • UTM ParameterAnalyticsTags added to the end of a link that tell your analytics where a visitor came from — which campaign, which channel, which post.

    Without them, traffic from your newsletter and your Instagram bio both land in the same undifferentiated bucket. Agree a naming convention once and stick to it.

V

  • Vanity MetricAnalyticsA number that looks impressive and changes no decision: follower counts, impressions, page views in isolation.

    The test is whether a change in the number would make you do something differently. If not, it belongs in a footnote rather than a report.

  • Video Completion RateSocialThe share of viewers who watched a video to the end.

    On short-form platforms this is close to the whole algorithm. The first two seconds decide it, which is why the hook gets rewritten more often than the rest of the script.

W

  • WebinarContentA scheduled online presentation, usually teaching something, used to gather qualified leads and sell to them at the end.

    Registrations are not attendance; expect between a third and half to show up live. The recording sent afterwards often produces more sales than the event.

  • White PaperContentA long, researched document making an argument, used mainly in business-to-business marketing as a lead magnet.

    It has to be genuinely researched to work. A sales brochure in a serif font and a PDF wrapper is recognised instantly and costs you the email address anyway.

  • Word of MouthStrategyCustomers recommending you to other people, unprompted and unpaid.

    Still the highest-converting channel there is, and the one least helped by marketing spend. It is built by the product and the service, then amplified by making referral easy.

Z

  • Zero-Click SearchSEOA search that ends without anyone clicking a result, because the answer appeared directly on the results page.

    Now a majority of searches. It makes ranking for simple factual questions much less valuable and raises the value of queries where people need to compare, buy or book.
