Ask what is digital marketing and you will get a different answer from every supplier, because the phrase covers a wide field and each supplier sells a different slice of it. That is how one quote arrives at a few hundred pounds a month and another at several thousand, with both of them honest.
The gap matters more here than the jargon suggests. There were 5.7 million private sector businesses in the UK at the start of 2025, and 5.64 million of them had fewer than 50 people, on the Department for Business and Trade's figures.
The House of Commons Library puts 95% of them below ten people. Most of the buying is therefore done by somebody with no marketing department to translate the quote.
You're too busy to do marketing properly, but not big enough to justify spending £2-3k a month and hoping for the best
A UK business owner, r/smallbusinessuk, June 2026
That is the position this post is written for. Not a marketing manager comparing tenders, but an owner quoted for digital marketing and unable to itemise it. So here is the whole field first, then the parts of it we sell, then a way to work out which parts you need.
What digital marketing actually covers
Digital marketing is the whole of getting a business found, considered and chosen online. The Chartered Institute of Marketing's channels course lists SEO, PPC, social media, content marketing, display advertising, email and websites, and even that list leaves out affiliate deals, influencer work and digital PR.
The money says the same thing. UK advertisers spent £40.5bn on digital advertising in 2025 on the IAB's figures: search took 44% of it at £17.9bn, social 28% at £11.5bn, video 23% at £9.3bn, and retail media grew 18% to £3.8bn.
No short definition accounts for that spread, and no single supplier sells all of it. We certainly do not.
| Part of the field | The job it does | How you pay |
|---|---|---|
| Search (SEO) | Being found in results you did not pay for | Work now, results later |
| Paid search (PPC) | Buying the click at the moment of the search | Per click, plus a fee |
| Social media | Being seen and answered on the feeds | Time, or ad budget |
| Staying in front of people who said yes | A platform, and restraint | |
| Content | Publishing answers people already want | Writing time |
| Display and video | Adverts placed around other people's content | Per view or click |
| Affiliate and influencer | Paying others to recommend you | Commission or fee |
| Digital PR | Coverage and links from publications | Outreach time |
| The website | Where every other row sends people | Build, then upkeep |
| AI search | Being named when somebody asks an assistant | Mostly search work, done well |

The six parts we sell at pomegranate
These are the six parts of the field pomegranate sells. They are not the whole of digital marketing, and no supplier's service list defines the field, ours included. They are the six that come up most often when a small business asks where to start, and why the published lists never agree on a number is a question in its own right.
Search
Search is the work of being found in results you did not pay for. It covers what the site is built from, what each page says, and who else on the internet refers to you.
It is the slowest of the parts we sell and the one that keeps working after you stop paying. Google Search is used by 82% of UK adults, on Ofcom's 2025 figures.
Paid search
Paid search answers the same question by buying the click instead of earning it. You appear at the moment somebody searches, you pay each time they arrive, and it stops the day the card does.
It is the fastest way in, and the £17.9bn above shows how much of the market buys attention rather than earning it. What that actually comes to a month is two numbers rather than one.
Social
Social is the part most people picture when they hear the phrase, because it is the part they can see. It covers what gets posted, what gets answered, and what gets advertised on those platforms.
It is demand creation rather than demand capture. Nobody on a feed was looking for you, which is why it is judged on different numbers from search.
Websites
The website is where everything else sends people, so its faults are charged to whichever channel delivered the visitor. A slow or unclear site reads as a failure of the ads that paid for the click.
Brand
Brand is what the business looks and sounds like before anyone has spoken to you. It has no channel of its own, which is why it is the easiest thing to defer and the most expensive thing to defer for long. If the word itself is doing too much work, start with what branding covers and what it is not.
AI search
AI search is the newest part: being named when somebody asks an assistant rather than a search box. About 30% of searches now show an AI summary, and 53% of adults say they see them often, on the same Ofcom release.
Most of the work behind it is the search work above, done well. The genuinely separate part is measurement, and anyone selling it as a wholly new discipline should be asked what is different about their method.
And the parts we do not sell are still real parts. If your problem is repeat purchases from people who already know you, that is email marketing, and the honest answer from us is a referral rather than a retainer.
Which one your problem needs
Buyers rarely arrive with a service in mind. They arrive with a sentence, and the sentence is usually enough to work out where to start.
- “Nobody can find us.” Start with search. You are missing from results you should be in, and paid advertising would rent you a position you could hold for free later.
- “We need customers this quarter.” Start with paid search, because organic search will not answer inside three months.
- “We get traffic but no enquiries.” The problem is the website, not the channel that filled it.
- “We post and nothing happens.” Social, but expect it to be judged on reach and replies rather than on immediate sales.
- “We look cheaper than we are.” Brand, and it usually shows up as losing quotes you should have won.
- “An assistant recommends somebody else.” AI search, on top of the search work rather than instead of it.
If two of those sentences sound like you, that is normal, and two is the usual starting point. If all of them sound like you, the honest answer is that the website and search come first, because everything else sends people to a place that has to hold them.
If you are not sure which sentence is yours, say what is happening in your own words and the diagnosis is usually quick.
What digital marketing is not
It is not any one supplier's service list, ours included. A supplier telling you the field is exactly the things they happen to sell is describing their catalogue, not the discipline.
It is not a guarantee of enquiries. Any part of it can be done competently in a market that is simply too crowded that quarter, and a supplier promising a number of leads is promising what they do not control.
It is not one channel wearing a general name. A quote for digital marketing that turns out to be social posting is not dishonest if it says so, and is close to useless if it does not.
It is not something that works in a month across the board. Paid search can report inside a fortnight. Search and brand answer over quarters, and a supplier who prices them identically has not thought about either.
It is also not unaccountable, whatever the reporting suggests. The most useful test in the whole category came from a UK owner in a thread about a four-figure retainer.
Ask them for a detailed breakdown of what they actually did with your grand a month. If they're unable to provide a substantive explanation then they'll have been doing the bare minimum; probably no more than an hour's work.
r/smallbusinessuk, October 2025
That question works on any part of the field, and it does not require you to understand the discipline to ask it. An answer in artefacts is a good sign, and what each service should actually hand you is set out line by line. An answer in adjectives is the finding.
How the parts fit together
A digital marketing plan is not a ladder anyone climbs in full. It is a question of what has to be true before the next thing repays its cost.
The website comes first, because it is where everything else delivers. Search comes next, since it compounds and the compounding starts the day it starts.
Paid search is right where the calendar will not wait for search, and for a seasonal business whose quarter is now. That is a legitimate reason rather than an upsell.
Brand runs alongside rather than in sequence, because it changes the conversion rate of everything else instead of adding a channel.
Social, email and content are the demand creation side, and they are genuinely optional at the start. They repay a business whose customers browse and share, and can be an expensive habit for one whose customers only ever search.
| Part | First results | What remains if you stop |
|---|---|---|
| Search | Months | Rankings and pages, still working |
| Paid search | Days | Nothing. It stops with the budget |
| Social | Weeks | The audience you built, slowly going quiet |
| Website | Immediately | The site itself |
| Brand | Quarters | The identity, indefinitely |
| AI search | Months | The citations behind the answers |
Paid search is the only row that stops dead, and the only one that starts quickly.
