Shopify articles post themselves →If an agency has quoted you £1,500 a month and you are wondering whether that is reasonable, the honest answer is: it depends entirely on what is inside the retainer. The SEO agency vs freelancer cost question is rarely about the headline number. It is about what each option actually delivers in output, strategy and oversight, and how much of your own time each one quietly consumes.
This article breaks down what agencies, freelance writers, DIY content tools and subscription writing services genuinely provide, so you can match the model to your budget and your appetite for involvement.
What £1,500 a month typically buys from an agency
A retainer at this level in the UK usually covers a mix of activities, not just writing. Expect some combination of a technical audit, keyword research, two to four articles a month, some on-page tweaks, link outreach and a monthly report. The exact split varies wildly between agencies, which is why two firms quoting the same figure can deliver very different things.
The strengths are real. A good agency brings strategy: they decide what to write, not just how to write it. They handle technical problems a writer never touches, such as crawl issues or site structure. And they carry accountability, in the sense that someone else owns the plan.
The weaknesses are equally real. Content volume is usually low relative to the spend, because your retainer is paying for account management, reporting and margin as well as the work itself. Turnaround on an individual article is often two to four weeks. And most agencies want a three to six month minimum commitment, on the fair grounds that SEO takes months to show results either way.
SEO agency vs freelancer cost: what actually changes
A competent freelance SEO writer in the UK typically charges somewhere between £100 and £400 per article depending on length, research depth and their experience in your sector. At four articles a month, that is roughly £400 to £1,600, so the raw cost can overlap with an agency retainer at the top end.
What changes is what the money buys. With a freelancer, almost all of your spend goes on the writing itself. You will often get better prose than an agency's junior content team produces, particularly if the freelancer knows your industry. Turnaround per piece is usually faster, and there is no long contract; most freelancers work per article or per month.
What you lose is the strategy layer. A freelance writer executes a brief. Someone still has to do the keyword research, decide the publishing cadence, brief each piece, upload it, add internal links and check what is working. That someone is usually you, and the hidden cost is two to five hours of your month, every month. There is also key-person risk: freelancers get busy, go on holiday, or raise rates, and your publishing schedule goes with them.
Rule of thumb: an agency sells you a strategy with some writing attached. A freelancer sells you writing with no strategy attached. Price the missing piece honestly before comparing the two.
What a content tool does, and what it cannot do
DIY content tools, the ones where you type a keyword and get a draft, cost anywhere from free to around £100 a month. On paper they look unbeatable: unlimited drafts for less than one freelance article.
In practice, the tool is the cheapest part of the job. What a generic drafting tool cannot do:
- Pick the keywords. It writes what you ask for. If you ask for the wrong topics, you get well-written articles nobody searches for.
- Know your business. Generic tools do not read your site, so drafts default to bland, interchangeable copy that could belong to any competitor.
- Publish and maintain. You still format, upload, link internally and submit for indexing yourself.
- Keep a cadence. The tool waits for you. Most owners who buy one publish enthusiastically for three weeks and then stop, which matters because consistency beats bursts in almost every case.
None of this makes tools bad. If you enjoy the work and have the hours, a tool plus your own judgement is the cheapest route by far. The point is that the £30 tool is not competing with the £1,500 agency; it is competing with your evenings.
One worry worth clearing up: Google does not penalise content for being AI-assisted, it penalises content that is unhelpful, whoever wrote it. We have covered what the guidelines actually say separately, but the short version is that quality and usefulness are what get judged.
The comparison at a glance
| Factor | Agency (£1,000 to £3,000/mo) | Freelance writer (£100 to £400/article) | DIY content tool (£0 to £100/mo) |
|---|---|---|---|
| Output volume | Two to four articles a month, plus other work | Whatever you commission and brief | Unlimited, if you do the work |
| Strategy included | Yes | No, you brief them | No |
| Turnaround | Two to four weeks per piece | Days to two weeks | Minutes to draft, hours to finish |
| Your time required | Low, monthly check-ins | Moderate, briefing and uploading | High, everything except the first draft |
| Commitment | Often three to six months minimum | Usually none | None |
How to choose based on budget and involvement
Work through these questions in order:
- Do you need more than content? If your site has technical problems, a messy structure or a penalty history, an agency earns its fee. Content alone will not fix a broken site.
- Do you know what to write about? If yes, a freelancer is excellent value. If no, a freelancer will faithfully write the wrong things, and you will not find out for six months.
- How many hours a month will you honestly spend on this? Not could spend. Will spend. If the answer is under two hours, rule out DIY tools and rule out managing a freelancer.
- What is your real budget? Under £100 a month means tools or a subscription service. £400 to £800 means a freelancer plus your own strategy time. £1,500 and up means an agency is on the table, provided the retainer breakdown stands up to scrutiny.
The most expensive option is the one that produces nothing, whatever it costs.
On that £1,500 quote specifically: ask the agency to itemise it. How many articles, what technical work, what reporting, and what happens in month one versus month four. A good agency answers in five minutes. A vague answer is itself an answer.
Where subscription writing services sit
There is a fourth model worth knowing about: subscription services that combine the tool's price point with some of the strategy layer. These typically scan your site, build a keyword plan, write on a fixed cadence and publish automatically, for somewhere between £30 and £100 a month. They do not replace an agency's technical work or link building, and they will not suit a business that needs hands-on consultancy. But for a small firm whose real problem is simply that nobody has time to write, they cover the gap between the DIY tool and the freelancer at a fraction of either's true cost. Consistent, well-targeted publishing also feeds the newer channel of AI assistants; if a competitor is already being mentioned in ChatGPT, a steady content base is where catching up starts.
Where Helio SEO fits in
Helio SEO is one of those subscription services: it scans your site, builds the keyword plan, writes in your voice and publishes automatically, at £29 a month for an article every other day or £49 for one every day. If you have the budget for a good agency and need technical work done too, an agency is still the right call. If you mainly need consistent, well-targeted articles without managing a writer or a tool yourself, this is the job we built it for, and the three-day trial will tell you quickly whether it fits.
