SEO Case Studies for UK Businesses: Four Verified Results and What Each Would Cost in GBP
A case study is only useful if you know two things: whether the figures are real and what the work cost. UK buyers rarely get either. These four engagements publish both: baselines and verified results from each client’s own analytics, and the engagement type behind each with its GBP range. Read the case closest to your firm, then use the checks below on every other agency’s page.
Key facts before you read
| Question | Answer |
|---|---|
| What is published | Four engagements: regulated financial services (page one in six months), B2B SaaS (+320% organic traffic), online retail (−40% blended acquisition cost) and jewellery retail (6× organic sales), each with baseline, sequence, verified figures, fit and GBP cost basis |
| How figures are verified | Taken from the client’s own Analytics, Search Console and CRM under read access, compared month-before-kick-off against a named month, and signed off by the client before publication |
| What each cost | Mapped in the pricing table to the engagement type behind it: managed programmes from £2,000 per month, eCommerce from £2,500, local SEO from £300 per branch; none ran on a fixed package |
| Time to result | Three months (jewellery), six (financial services), eight (SaaS), ten (online retail); technical fixes landed first, decision-stage pages reached page one in three to six months, compounding followed |
| What is withheld | Client names, under NDA at their request; prospective UK clients can see the underlying data and, where the client agrees, speak to them |
| What these are not | Not average outcomes, not forecasts, and not a claim that FCA-regulated finance, health or legal categories in the UK move as quickly as retail |
| Where to check an agency’s claims | The comparison table below lists six checks (source, baseline, metric, consent, timeframe, limits) that any UK case study should pass |
| How we decide | Data-driven: every recommendation starts from your Search Console, analytics and competitor data, and every month is reported in enquiries, calls, forms and sales, not rankings alone |

Which case fits your firm
Choose by how your business earns revenue rather than by the largest percentage. The right-hand column is what the free audit reports before any proposal is written.
| Your situation | Read first | Why this case | What the free audit shows |
|---|---|---|---|
| Fintech, lender, insurer, wealth or advice firm where compliance signs off every page | Financial services: page one in six months | A YMYL category where compliance-reviewed content, E-E-A-T signals and earned authority decided rankings; the sign-off workflow maps onto FCA financial-promotion rules | Your approval path, the high-intent terms within reach and the authority gap against incumbents |
| B2B SaaS or software firm with product pages stuck on page two and a pipeline that leans on paid search | SaaS: 320% organic growth | Identical ceiling: technical issues capped the site, high-intent theme pages were missing, authority was thin; the fix order transfers | Which ceiling is yours, the themes with demand on google.co.uk and a 90-day sequence tied to demo requests |
| Online retailer whose paid acquisition cost climbs while organic revenue stays flat | eCommerce: 40% lower CAC | Category architecture, technical fixes and buying-guide content lifted organic revenue share from 14% to 41% and cut blended acquisition cost 40% | Indexable catalogue count, category gaps against Amazon listings and your organic revenue baseline |
| High-street retailer with branches and an online shop in a crowded category | Jewellery: 6× organic sales | Category, product and local SEO together took organic revenue share from 8% to 34% in one quarter | Branch-level visibility, product pages that can rank and the first-quarter plan |
| You want AI search visibility (AI Overviews, ChatGPT citations), not rankings alone | AI SEO UK | No AI-visibility case is published yet because none has run long enough with client consent; the service page sets out what is measured | Current AI Overview and assistant citations for your category and the pages that would earn them |
| Unsure which applies, or whether SEO is the constraint at all | Free audit, then the case we point you to | The audit names the ceiling (technical, content, authority or conversion) first; sometimes the answer is that SEO is not the bottleneck | Prioritised issues, the closest case and a GBP estimate within 3 working days |
| The site is the problem: slow, dated, or built with no search plan | Web development UK | Two of the four cases needed structural fixes before content could rank; where a site cannot be fixed in place, a rebuild comes first | Whether the ceiling is fixable in place or needs a rebuild, with the cost of each |
The four case studies
One page per engagement. Each sets out the position before kick-off, the order the work shipped in, the verified before-and-after figures against named months, the GBP cost basis and the UK firms the plan would suit.
All four results side by side
The only table here listing every case together; the GBP cost basis of each sits in the pricing table further down.
| Case | Baseline | Work done | Verified result |
|---|---|---|---|
| Regulated financial services brand · 6 months | Compliance sign-off on every page, six keywords on page one, thin authority | Compliance-approved content, trust and expertise signals, links aimed at money pages | Page one for high-intent terms; page-one keywords from 6 to 73; enquiries from 12 to 61 a month; organic clicks from 1,900 to 8,400 |
| B2B SaaS platform · 8 months | Core commercial terms on page two, pipeline reliant on paid search, crawl and speed ceiling | Technical foundation rebuilt, high-intent theme pages, authority, demo reporting | Organic sessions from 4,200 to 17,600 a month; page-one keywords from 18 to 210; demo requests from 9 to 58 a month |
| Online retailer · 10 months | Paid acquisition cost rising, organic revenue share stuck at 14% | Category architecture, technical fixes, buying-guide content | Organic sessions from 22,000 to 78,000; organic revenue share from 14% to 41%; blended acquisition cost down 40% |
| Jewellery retailer, branches plus online · 3 months | Crowded category, organic revenue share 8% | Category, product and local SEO with supporting content | Organic sales up 6×; organic traffic up 180%; organic revenue share from 8% to 34% |
| Common thread | A fixable ceiling, genuine demand, a team that implemented | Ceiling first, decision pages before volume, authority on converting pages, reporting in the client’s numbers | Three to ten months; no guarantees, no averages |
Six checks for any UK SEO case study
Before a case study influences your shortlist, run it through these checks. They apply to ours as much as to anyone else’s.
| Check | These four cases | What to be wary of |
|---|---|---|
| Data source | Client’s own Analytics, Search Console and CRM under read access | Rank-tracker screenshots or unnamed “internal data” |
| Baseline | Month before kick-off against a named month, absolute figures given | A percentage with no starting figure or dates |
| Metric that matters | Enquiries, demo requests, revenue share, sales | Traffic or “keywords ranked”, often brand terms |
| Client consent | Published with sign-off; names withheld under NDA at the client’s request; data available on request | Logo walls with no detail, or results the client never saw |
| Timeframe | 3, 6, 8 and 10 months, with what moved first | No timeframe, or “in weeks” |
| Limits and cost | Each page says who the plan does not fit, nothing is guaranteed, and the GBP cost basis is shown | Guarantees, no cost basis, or the implication that every client gets the same |
What every case page documents
- ✓Position before kick-offRankings, channel mix, technical state and the commercial problem in the month before work began.
- ✓The blocker cleared firstWhatever stopped new pages ranking: crawl, indexation, rendering, speed or compliance.
- ✓Order of deliveryWhat shipped when, and why decision-stage pages preceded informational content in every case.
- ✓Where links wentWhich pages received authority and why they were chosen over the blog.
- ✓Verified figuresAbsolute before-and-after numbers from the client’s own systems, both months named.
- ✓Cost basis in GBPThe engagement type behind the case and its market range, so you can price a comparable programme.
- ✓Fit for UK firmsSectors, sizes and situations the plan suits, where it would not, and what evidence is available under NDA.
What each engagement would cost in the UK
Each case maps to an engagement type in our UK SEO pricing guide; market ranges come from that guide and the right-hand column is where our programmes start. Figures in GBP, quoted after a free audit.
| Engagement behind the case | UK market range | Ren Hao SEO |
|---|---|---|
| Free summary audit (every case began here) | Free from most agencies, depth varies | Free; prioritised issues, the closest case and a recommended service within 3 working days |
| Compliance-led managed programme (financial services case) | £2,500–£6,000 per month in regulated sectors | From £2,000 per month with compliance sign-off built into the content workflow |
| Managed SEO programme (SaaS case) | £1,500–£5,000 per month; UK median about £2,500 | From £2,000 per month, month to month |
| eCommerce SEO programme (online retailer case) | £1,500–£8,000+ per month by catalogue size | From £2,500 per month |
| Local plus eCommerce SEO (jewellery case) | Local SEO £300–£800 per branch per month, plus the eCommerce range | Quoted per branch after the audit; multi-branch from £1,000 |
| Full SEO audit or migration (one-off) | £2,000–£8,000 by site size | From £2,000; fee credited against the first programme month |
| Technical fixes or rebuild before SEO | Project-priced | Fixes quoted after the audit; rebuilds from £1,000 one-off under web development |
None of the four ran on a fixed package; each was a month-to-month programme re-weighted quarterly toward what converted, which is why ranges rather than one price are shown.

Frequently asked questions
Are these SEO case studies real?
Yes. Each figure comes from the client’s own Google Analytics, Search Console and CRM or e-commerce platform under read access and was signed off by the client before publication. Names are withheld under NDA at the client’s request, and the data is available to prospective clients under the same terms.
What did each engagement cost?
The pricing table above maps each case to its engagement type and GBP range: the SaaS case ran as a managed programme (ours from £2,000 per month), the financial services case as a compliance-led programme (from £2,000), the online retailer as an eCommerce programme (from £2,500) and the jewellery retailer as local plus eCommerce SEO (quoted per branch, multi-branch from £1,000). None was a fixed package; each was month to month and re-weighted quarterly.
Can you repeat these results for my UK business?
We can tell you after a free audit. If your site has a fixable ceiling, your category has real demand on google.co.uk and your team can implement, one of the four plans usually applies and the audit sets out the first ninety days. If not, we say so and propose a different sequence, or tell you SEO is not the bottleneck.
Do you have an AI SEO case study?
Not yet as a published case. AI Overview and assistant-citation tracking runs inside current programmes, and a case will be published when one has run long enough and the client agrees; the AI SEO service page explains what is measured. We will not publish an AI result that cannot be verified the way these four are.
How long did each result take?
Three months for the jewellery retailer, six for the financial services brand, eight for the SaaS platform and ten for the online retailer. Technical fixes showed first, decision-stage pages usually reached page one within three to six months once the ceiling was removed, and compounding growth took six to twelve.
How do I check another agency’s case study?
Ask for the data source, the baseline month and absolute figures, a metric the business cares about, proof the client agreed, the timeframe and a statement of limits. If any of the six is missing, treat the result as marketing copy rather than evidence; the comparison table above shows how these four answer each.
Do you guarantee rankings?
No. Guaranteed-ranking claims are not credible and fall foul of the CAP Code. We commit to a documented plan, agreed milestones, enquiry-and-revenue reporting and month-to-month terms so you can leave if the work is not delivering.
