Case Study: How Strategic SEO Increased Organic Leads by 247% for a B2B SaaS Company
Client Overview
A UK-based B2B SaaS provider offering workflow automation solutions for regulated industries approached us in early 2024. Despite having a strong product and a technically sound website, their organic traffic had plateaued for over a year, and the site generated very few inbound leads. The marketing team had previously focused on paid campaigns but wanted to establish sustainable, compounding growth through SEO — without heavily increasing ad spend.
Challenge
After the initial audit, we identified several critical obstacles:
Keyword strategy misalignment
The site targeted overly generic, high-competition phrases such as "automation software" instead of conversion-focused B2B terms like "workflow automation for pharmaceuticals."
Weak topical authority
Blog content was inconsistent and didn't connect to service pages.
Technical gaps
35% of pages were non-indexable due to incorrect canonical tags; site speed lagged behind competitors by 35%.
Low lead intent
The top-ranking pages attracted visitors seeking definitions, not solutions.
In short, the website had visibility but not relevance.
Objectives
We defined measurable targets for the first six months:
  • Increase qualified organic traffic by 100%.
  • Double the number of keywords in the top 10 positions.
  • Generate a consistent flow of inbound demo requests from organic search.
SEO Strategy
1. Full-scale keyword and intent mapping
We rebuilt the site's keyword structure from scratch using a cluster-based approach:
  • Divided topics into three layers — Core Services, Supporting Topics, and Conversion Assets.
  • Identified 125 high-intent keywords with KD < 50 and mapped them to landing pages.
  • Grouped long-tail terms for each buyer stage — awareness, evaluation, decision.
Result: each key page had a clear keyword purpose, semantic context, and conversion goal.
2. Topical authority through strategic content clusters
To strengthen relevance, we created five interconnected content clusters targeting niche pain points:
Each cluster internally linked back to its service page, boosting both topical authority and crawl efficiency.
3. Technical optimisation and crawl equity
We executed a full technical clean-up in the first month:
  • Fixed canonical tags, sitemap inconsistencies, and duplicate meta data.
  • Improved Core Web Vitals (LCP from 4.1s → 2.3s).
  • Implemented structured data for services, FAQs, and breadcrumbs.
  • Compressed heavy JavaScript, increasing the crawl rate by 38%.
4. Content refresh and semantic optimisation
We audited the existing blog archive (64 articles) and categorised them into three groups:
  • Update & keep (optimise for new AI search patterns, rewrite intros).
  • Merge (combine overlapping posts).
  • Remove (outdated or thin content).
We rewrote key articles to include entities, schema markup, and clearer intent cues, resulting in an average +0.8 position gain within 6 weeks.
5. Authority Building (Link Strategy)
Instead of generic link-building, we focused on relevance and credibility:
  • published guest posts on niche SaaS and automation blogs;
  • earned mentions in TechBullion and Dev.to;
  • created original research on workflow ROI that generated 40+ organic backlinks.
Average Domain Rating (Ahrefs) increased from 39 to 56 in five months.
Results
Highlights:
  • The new content cluster on workflow automation alone drove 9,000+ additional visits per month.
  • 3 blog posts were featured in Google SGE snippets, increasing AI visibility and generating +12% incremental traffic.
  • The client reduced paid ad spend by 35%, redirecting the budget into content expansion
Key Takeaways
SEO is no longer just about ranking
It's about discoverability across AI and traditional search. By integrating AI visibility tracking into the strategy, we ensured the brand appeared in both Google SGE and Perplexity citations.
Topical authority outperforms keyword density
Building a strong internal linking structure and semantic clusters made Google treat the domain as an authority source.
Data transparency drives better decision-making
The GA4 + Looker Studio dashboard allowed the client to monitor organic performance in real time and link it to revenue outcomes.
Long-term impact over quick wins
Organic traffic remained stable after the initial six-month sprint, with steady growth of ~8% month-over-month.
Conclusion
This case demonstrates how strategic SEO and AI-driven optimisation can transform a plateaued website into a scalable lead-generation engine. By focusing on data-driven keyword clustering, technical excellence, and AI visibility analytics, the client built sustainable organic growth — not just more traffic, but better-qualified leads.
