USP
Unique selling pointThe reason someone chooses you over the two or three others they are actually considering — not the reason you are unlike every business in the country.
Why it matters. Your customer has a shortlist, not a survey. Being visibly different from the other names on that shortlist is a far lower bar than being unique, and it is the only bar that ever gets tested.
Common mistake. Claiming something a competitor could never claim the opposite of. Nobody advertises shoddy work or unfriendly staff, so "quality workmanship" and "friendly service" are the price of entry rather than a reason to pick you.
Conversion
The action you wantedA visitor doing the thing the page existed for — booking, enquiring, buying, calling.
Why it matters. Defining the conversion before you spend anything is what stops you judging a campaign by whether the number felt large.
Common mistake. Having several. If a page is asking for four different things, it is usually getting none of them.
Call to action
The instructionThe specific next step you are asking for, in plain words: Book a slot, Get a quote, Call us today.
Why it matters. The most common weakness in small business content is beautiful work with no indication of how someone would get that done for themselves.
Common mistake. Being polite to the point of vagueness. "Get in touch to find out more" asks for nothing in particular.
Landing page
Where the link goesThe page someone arrives on from an advert, post or link — ideally one that matches what they just clicked.
Why it matters. Sending paid traffic to a homepage is a reliable way to lose the visitor you just paid for.
Lead
Someone who has raised a handA person who has given you a way to contact them — an enquiry, a form, a call, a message.
Why it matters. Leads are the thing most service businesses should measure, because a sale usually happens later and offline.
Customer lifetime value
What a customer is worth in totalWhat a typical customer spends with you over the whole time they stay, rather than in one transaction.
Why it matters. Without it you cannot tell whether an acquisition cost was good, and you will judge spending by whether the total felt like a lot of money.
Attribution
Deciding what gets the creditAssigning responsibility for a sale to the marketing that preceded it.
Why it matters. Some signals are direct — a tracked link, a code used, a booking record. Those are evidence.
Common mistake. Treating a coincidence as proof. "Bookings rose during the campaign" is an observation; "this post caused £4,000 of sales" is a causal claim needing much stronger evidence.
Social media
The metrics platforms report, and what they are actually telling you.
Reach
How many people saw itThe number of distinct accounts that saw a post at least once.
Why it matters. Useful for comparing your own posts against each other over time.
Common mistake. Treating it as the goal. For a local business the potential audience is a few thousand finite people — recognition over time matters more than reach on any one post.
Impressions
How many times it was shownThe number of times a post was displayed, including repeatedly to the same person.
Why it matters. Impressions are always higher than reach. Comparing one to the other across platforms is meaningless because each defines them slightly differently.
Engagement
Reactions, comments, shares, savesAny interaction with a post. Engagement rate expresses that as a proportion of reach or followers.
Why it matters. Useful for comparing creative work — which of your posts held attention.
Common mistake. Reporting it as a business result. An engagement is not revenue, and paying to optimise for engagement reliably finds people who react and do nothing else.
Organic
UnpaidAnything you get without paying for placement — normal posts, shares, people finding you.
Why it matters. Organic keeps working after you stop spending, which is exactly why it behaves differently from advertising when money is tight.
Algorithm
What the platform chooses to showThe ranking system deciding which posts appear in whose feed, and in what order.
Why it matters. It changes, without notice, and differs per platform. That is why any specific posting frequency or format advice ages badly.
Common mistake. Building a strategy around a rumoured algorithm rule. Build it around being consistently worth watching instead.
Professional account
Business or CreatorA non-personal account type that several platforms require before they allow scheduling or third-party publishing.
Why it matters. This is the single most common reason a connection to a scheduling tool refuses. Switching is done inside the platform, is normally free, and usually unlocks the platform’s own analytics too.
