SEO Case Studies for UK Businesses: Four Verified Results, the Evidence Behind Them and What Each Costs in GBP
Four SEO engagements with figures taken from each client’s own Google Analytics, Search Console and CRM and reviewed with the client before publication. UK readers are right to be sceptical: the UK agency market is full of case studies without numbers, numbers without sources and results that depended on a twelve-month contract the client could not leave. These four are published the way the CAP Code expects claims to be made, with the evidence held and available under NDA, and each is mapped below to the UK business it corresponds to: a SaaS company dependent on paid search, a brand whose content goes through FCA financial promotion review, an online retailer losing margin to Amazon.co.uk and Meta ads, or a jeweller with shops in several towns. The GBP plan behind each is stated, and every engagement ran month to month.
Four documented results at a glance
Each row links to the full case study and names the UK business it maps to; budgets are in GBP from our UK pricing guide and exclude VAT.
| Case | Starting point | What was done | Result | Services behind it |
|---|---|---|---|---|
| B2B SaaS platform (maps to a UK software company selling to mid-market buyers at home and in the US) | Commercial pages on page two; demos from paid search; technical problems holding the site down | Ceiling removed, decision-stage theme content, authority building, pipeline reporting | +320% organic traffic, 11× page-one keywords, 6.4× demo requests in 8 months | UK industry SEO; managed programme from £2,000 a month |
| Regulated financial services brand (maps to a lender, broker, fintech or wealth firm under FCA financial promotion rules) | YMYL category; every page through compliance; weak authority | Compliance-reviewed content, named-expert signals, authority earned from relevant sources | Page one for high-intent terms, 5× organic enquiries, 4.4× organic clicks in 6 months | UK industry SEO; managed programme £2,500–£5,000 a month |
| Online retailer (maps to a UK Shopify or Magento store competing with Amazon.co.uk and marketplaces) | Cost per customer rising; organic 14% of revenue | Category architecture, technical fixes, buying guides | −40% blended CAC, 3.5× organic sessions, organic revenue share 14% → 41% in 10 months | SEO services UK; eCommerce programme £1,500–£8,000 a month |
| Jewellery retailer, online and in-store (maps to a jeweller with shops in several UK towns and an online store) | Competitive category; organic 8% of revenue; shops not in the map pack | Category and product SEO, shop-level local SEO, content | 6× organic sales, +180% organic traffic, organic revenue share 8% → 34% in 3 months | Local SEO UK plus category SEO; from £300 per branch |
Every result here came out of the same process our UK SEO team runs for each client: a data audit first, then a prioritised roadmap, then monthly execution.
The case studies
The four case studies in full (4)
320% Organic Traffic Growth for a B2B SaaS Platform
B2B SaaS · 8 months. A B2B software platform stuck on page two for its commercial terms, with demos coming mainly from Google Ads and technical problems holding the site down. Eight months later: organic sessions 4,200 to 17,600 a month, page-one keywords 18 to 210, demo requests 9 to 58. For a UK SaaS company the same sequence applies, with US sites as the main competition on google.co.uk for most English terms.
- +320%Organic traffic
- 11×Page-one keywords
- 6.4×Demo requests
Page One in Six Months for a Regulated Financial Services Brand
Financial services · 6 months. A financial services brand where every page went through compliance and authority was weak. Six months of compliance-reviewed content, named-expert signals and authority work put the high-intent terms on page one: page-one keywords 6 to 73, organic enquiries 12 to 61 a month, organic clicks 1,900 to 8,400. The UK equivalent is a lender, broker or wealth firm whose content goes through FCA financial promotion sign-off.
- Page 1High-intent terms in 6 months
- 5×Organic enquiries
- 4.4×Organic clicks
40% Lower Customer Acquisition Cost for an Online Retailer
eCommerce · 10 months. An online retailer whose cost per new customer rose every quarter while organic sat at 14% of revenue. Ten months of category architecture, technical fixes and buying guides moved organic sessions from 22,000 to 78,000, organic revenue share to 41% and blended acquisition cost down 40%. For a UK store the competition is Amazon.co.uk and marketplaces; the answer is own-brand category pages with delivery and returns content they cannot match.
- −40%Blended acquisition cost
- 3.5×Organic sessions
- +27 ptsOrganic revenue share
6× Organic Sales for a Jewellery Retailer in Three Months
Jewellery retail · 3 months. A jeweller with shops and an online store in a competitive category, with organic at 8% of revenue. One quarter of category, product and local SEO produced six times the organic sales and 180% more organic traffic, with organic revenue share at 34%. The closest UK case is a jeweller with shops in several towns, each needing its own map-pack position, and an online store competing on the same category terms.
- 6×Organic sales
- +180%Organic traffic

How we verify and publish results
Each number on these pages was pulled from the client’s own Google Analytics, Search Console and, where enquiries or revenue are reported, their CRM or e-commerce platform, with the client’s read access, and the client reviewed the case before it went live. Comparisons are the month before kickoff against a named month of the engagement; page-one counts come from Search Console. Names are withheld under NDA. The evidence is held and available to prospective clients on request under the same terms, which is the standard the Advertising Standards Authority applies to any objective claim: documentary proof before the claim is made. Each engagement ran month to month, so no result depended on a client being unable to leave.
What the four cases have in common
- ✓The technical ceiling came off firstCrawl, indexation, rendering and speed problems were fixed in all four before new content was written, so the later work could rank instead of stalling.
- ✓Pages that convert were built before pages that informService, product, category and comparison pages came first; informational content followed and supported them.
- ✓Every link was aimed and every link was listedAuthority went to the pages carrying the commercial terms, from real sites, with each link reported to the client.
- ✓The plan answered to the client’s numbers, not to a contractDemo requests, enquiries, revenue share or sales from the client’s own systems decided each quarter’s work; the budget stayed because the numbers justified it, not because a twelve-month term required it.

How an engagement runs from here
- 1Free audit, no sales sequence (days 1–3)Send your domain and three competitors on google.co.uk; you get a top-line audit, the case closest to you and a GBP estimate, with nothing to sign.
- 2Audit, plan and tracking (weeks 1–3)Technical, content, authority and conversion audit, a plan with milestones, and enquiry and revenue tracking configured under UK GDPR and PECR.
- 3Monthly delivery with every link listed (from week 3)Technical fixes, decision-stage pages, content and links against the plan; you see the work queue and each link placed every month.
- 4Monthly report, quarterly re-plan, thirty days’ noticeEnquiries, revenue and pipeline from organic each month; each quarter the plan moves toward what converted, and you can leave at any point with thirty days’ notice.
An honest note on results
Four cases appear here because four clients agreed and four sets of figures stood up to their own checking. They are not an average of every engagement, and the CAP Code and the Business Protection from Misleading Marketing Regulations would not allow them to be presented as a promise even if we wished to. What the four shared was a fixable problem, real demand and a team that implemented, which is why results came in three to ten months. A UK site competing with Amazon.co.uk or national brands on head terms should expect longer. Google’s results are nobody’s to guarantee, so we report enquiries and revenue, set milestones by stage and work month to month; the free audit is where we say which of these applies to you, including when SEO is not the bottleneck.
