Three proposals open in three tabs, three prices, and three quietly different definitions of the word "article". That is where most of these decisions start, and it is why choosing an SEO content writing service is harder than it looks: every result on page one for that search is a sales page written by a provider who wants the job. None of them are going to hand you the questions that would expose them.

So here are those questions. Twelve of them, drawn from how a research-first editorial pipeline actually runs, plus a scoring sheet you can work through on a single call. Use it on us if you like.

What an SEO content writing service actually delivers, and what it leaves out

Nearly every provider claims the same four things: keyword research, writing, optimisation, publishing. Those four words hide almost everything that matters.

"Keyword research" can mean a live analysis of what currently ranks for your target query, or it can mean someone filtered a spreadsheet export by search volume in March and has been working through it ever since. "Writing" can mean a subject-matter interview and a named writer, or a prompt and a spellcheck. "Optimisation" often means a plugin turned green. "Publishing" frequently means a Google Doc lands in your inbox and the actual publishing becomes your problem.

Then there is the list of things that fall outside the quote entirely: images, schema markup, internal linking, meta fields, and any reporting that would tell you whether the work did anything. Ask for each of those by name. The gap between the proposal and the invoice is usually built out of exactly those items.

The three delivery models, and what each is genuinely good at

• A freelance SEO copywriter. Best when you already know what you want written and can brief it. You get one brain, one voice, real accountability. You also get their holidays, their bandwidth ceiling, and usually no publishing, no imagery and no technical checks.

• An agency retainer. Best when content is one part of a wider strategy and you need someone to own the plan. More expensive per article, slower to start, and the person who sold it to you is rarely the person writing.

• A blog content subscription service or platform. Best for consistent cadence at a predictable monthly cost, with the workflow (brief, draft, images, publishing) handled end to end. Weakest where the topic needs a real interview with an engineer or a founder, unless the process explicitly makes room for that.

Word count is the wrong unit of value, and it is the unit most quotes are built on. A 2,000-word article planned against the wrong query is worth less than a 900-word piece that answers the question people are actually typing. Judge on research depth and sustained cadence instead.

Questions about research: how do they decide what to write?

Question one is the most diagnostic thing you can ask: what is each brief planned against?

A provider planning every brief against the live Google top 10 for that exact query is solving a different problem from one working off a keyword list exported months ago. The first is looking at what Google currently rewards for that search: the angle, the depth, the format, the questions the existing results answer and the ones they all skip. The second is guessing. That difference shows in the first draft, not in month six.

Two: where does the keyword data come from, and how often does it refresh? Volume and difficulty figures pulled once at onboarding go stale. Ask whether the numbers are UK-specific and refreshed on a regular cycle, weekly rather than annually, because a brief aimed at a query that has since shifted intent is wasted money you will not notice for two quarters.

Three: do you run a keyword-gap analysis, and against how many competitor sites? Gap analysis run against one named rival tells you very little. Run against 5 to 10 crawled competitor sites, it starts to show you the queries your market covers and you do not.

Four: do you crawl my site first, and how many pages? Any recommendation made without reading your existing pages is a recommendation made blind. We read your website like a new hire would, and we crawl it politely, because you cannot sensibly plan the next twenty articles without knowing what the current forty are doing.

Questions about voice: how will this sound like your business?

Five: how is the brand voice profile built? If the answer is a tone-of-voice questionnaire with adjectives on it, expect adjective-shaped writing. "Friendly, professional, approachable" describes roughly every company in Britain. Voice is learned from your own existing writing: your about page, your case studies, the way your founder answers an email.

Which creates an honest constraint worth raising out loud. If your site has three pages of copy, there is very little for a voice profile to learn from. A provider who promises to nail your voice off a thin site is guessing. The better answer is to say so, agree a starting point with you, and tighten it over the first few pieces. Our own approach to building a brand voice profile from your existing writing works the same way, and we say the same thing to clients with thin sites.

Six: what does a human do to the draft, and at what stage? "Do you use AI?" is the wrong question in 2025, and providers have learned to answer it with a straight face either way. Google's own guidance, published on Search Central in February 2023, is that rewarding high-quality content matters more than how it was produced. Google doesn't penalise AI content. It penalises badly written content. Ask where the human sits in the chain and what they are empowered to change.

Seven: what phrasing do you ban, and can I see the list? Most AI writing has a tell, and the tell is pattern rather than error: vague filler that could describe any business in the sector, an unnaturally even sentence rhythm where every sentence runs the same length, and the same stock phrasings recurring across every piece. The counters are first-hand specificity, deliberate rhythm variation, and a maintained banned-phrase list. Ask to see theirs. Most do not have one.

Questions about quality control: who says the draft is good enough?

Eight: what gets graded, against what, and which score wins when they disagree? A single SEO score is a poor gate, because it rewards structure over substance. Correct heading hierarchy, keyword in the first paragraph, decent length, green light. The article can still say nothing at all.

Two scores fix that: one for how well the piece is likely to rank, one for content integrity, meaning whether a human expert would put their name to it. When the two conflict, integrity should win. A piece that scores well on SEO and thin on integrity is exactly the piece that gets you a ranking for a fortnight and a reputation problem for longer.

Then a sceptical sub-editor read before anything goes live. Not a proofread. A read that asks whether each claim is supported, whether the headings promise more than the sections deliver, and whether any paragraph exists purely to reach a word count.

Nine: what happens to a piece that fails? Rewrite, reject, or ship it anyway. That answer tells you more about a provider than anything else in the conversation, and you should ask what the actual rate is. A process that has never rejected anything is not a process.

Questions about publishing: does it reach your site without a copy-and-paste queue?

Publishing is where most retainers leak time. The drafts arrive, the person with the CMS login is busy, and three articles sit in a folder for a month.

Ten: which platforms do you publish into directly, and what schema do you add? Direct API publishing into WordPress, Webflow, Framer, Shopify or Wix, with clean HTML or Markdown export for Squarespace, removes the queue entirely. On markup, three types are worth insisting on for a blog: Article, Breadcrumb and FAQ. And the detail nobody mentions: if Yoast or a similar plugin is already emitting Article schema, adding a second set creates duplicate markup rather than better results. The system needs to detect the plugin and stand down.

Eleven: how do you check for cannibalisation before writing? Cannibalisation is not only something you inherit. Content services create it. Without a check against your existing pages and every article the provider has already published for you, a monthly retainer will eventually commission a piece that competes with something the same provider wrote two quarters earlier. Ask whether the check runs before the brief is written, not as a quarterly audit that finds the damage afterwards.

While you are there, ask about ramp-up. A site that has published nothing for twelve months and then pushes 30 posts in a fortnight looks like exactly what it is. A gradual cadence is safer, and it matters most for the sites least used to publishing.

Twelve: who owns the content, the images and the login access when you leave? Get it in writing. Ask specifically about imagery, because on-brand images generated from your real palette, logo and font in blog, Open Graph and social sizes are a different deliverable from generic stock, and you want to know which one you are buying and in which sizes.

What SEO content writing costs in the UK, and what each band buys

Content marketing pricing in the UK comes in four shapes: per word, per article, monthly retainer, and subscription. Per-word rates tell you almost nothing on their own, because they price the typing and ignore the research. The Chartered Institute of Editing and Proofreading publishes suggested minimum rates for editorial work, and the CIEP's guidance is a useful sanity check on what skilled human editorial time actually costs before anyone adds strategy on top.

The cheap end goes wrong in a predictable way. No research, no brief, no editing, and content that needs rewriting inside six months, by which point you have paid twice and lost the year. Cheap content is rarely a bargain; it is deferred cost.

The costs buyers forget are the ones sitting outside the article: images in the right sizes, schema, the internal linking pass, the CMS time, and the reporting that tells you whether any of it moved. Ask for an all-in monthly figure with those included, then divide by articles published, not articles delivered. Our own plans and monthly pricing are published openly for that reason, though check the current figures rather than trusting a page you read six months ago.

A scoring sheet for shortlisting providers

One point per question. Score each answer as clear, vague or absent. Anything under eight clear answers, keep looking.

1. What is each brief planned against? (Live top 10 for the query, or a keyword list?)

2. Where does the keyword data come from, and how often does it refresh?

3. Do you run a keyword-gap analysis, and against how many competitor sites?

4. Do you crawl my site first, and how many pages?

5. How is my brand voice profile built, and from what source material?

6. What does a human do to the draft, and at what stage?

7. What phrasing do you ban, and can I see the list?

8. What gets graded, against what, and which score wins the tie?

9. What happens to a piece that fails the grade?

10. Which CMS do you publish into directly, and what schema do you add?

11. How is cannibalisation checked before a brief is written?

12. Who owns the content, the images and the logins when I leave?

Cadence is the thirteenth thing to raise, but treat it as a conversation rather than a pass or fail: you want a ramp that suits a site's publishing history, not a fixed number someone put in a slide.

Red flags: guaranteed rankings, a fixed word count as the headline promise, no named writer or editor anywhere in the process, and a blank look at the word cannibalisation.

Green flags: they ask to crawl your site before quoting, they show you a brief before writing a word, and they tell you plainly what they will not do. That last one is rarer than it should be. A provider who admits your thin site limits the voice profile, or that a technical piece needs twenty minutes with your engineer, is a provider paying attention. You can see how we set out the research, drafting and publishing sequence if you want a reference point for what a full answer looks like.

How to run a paid trial article properly

A paid trial is the cheapest test available. Agree one brief, one deadline and one revision round, and pay for it, because free samples get written by whoever is spare. When it lands, ask a single question: does this contain anything a competitor could not have written about themselves? If every sentence would survive a find-and-replace of your company name, the research did not happen. Check the revision too. How a provider handles being told the draft missed is more informative than the draft.

Whichever way you go, freelance, agency or an SEO content writing service that runs the whole workflow, the questions above cost you one phone call and save you a year of publishing into the void. If you would rather start with an outside read of where your content currently stands, our free content marketing snapshot is a reasonable first step.

Frequently Asked Questions

How much does an SEO content writing service cost in the UK?

Pricing usually comes as a per-word rate, a per-article price, a monthly retainer or a subscription plan, and the spread is wide because the underlying work varies so much. The number to compare is the all-in monthly cost including research, images, schema, publishing and reporting, divided by articles actually published. Ask every provider to quote on that basis, and check current pricing directly rather than relying on figures you saw last year.

Is a freelance SEO writer or a content subscription better for a small business?

A freelance writer suits you if you can write briefs, already know your topics and only need a few pieces a quarter. A blog content subscription service suits you if the real problem is consistency, because it handles briefing, imagery and publishing as well as the writing. If your bottleneck is time rather than words, the subscription model usually wins.

How can I tell if an SEO content writing service uses AI?

Ask what a human does to the draft and at what point, rather than asking whether AI is involved. Then read a sample for pattern: filler that could describe any company, an unnaturally even sentence rhythm, and the same phrasings appearing across different articles. Asking to see a banned-phrase list is a fast filter, since providers who take the problem seriously maintain one.

How many articles a month should a small business publish?

Fewer than most providers sell, and more consistently than most businesses manage. A site with little publishing history should ramp gradually rather than launching a large batch at once, because a dormant blog that suddenly posts dozens of pieces in a fortnight looks exactly like what it is. Steady output you can sustain beats a burst you abandon.

Who owns the content an SEO writing service produces for me?

That depends entirely on the contract, so get it in writing before the first invoice. Confirm ownership of the written content, the images and any accounts or logins created on your behalf, and check what happens to published work if you cancel. Reputable providers hand everything over without argument; the question is whether the paperwork says so.
