+320% Organic Trial Signups — B2B SaaS SEO Case Study

The Challenge

A B2B SaaS platform in a competitive productivity and workflow category was spending £45,000/month on paid acquisition with declining CPAs and a rising cost per trial signup. Organic search accounted for less than 8% of total signups despite representing 60% of the buying journey's research phase.

The site had minimal informational content, no comparison pages targeting competitor alternatives queries, and no integration or use-case pages — leaving enormous bottom-of-funnel organic opportunity unaddressed.

Our Approach

Phase 1: Keyword Architecture and Audit (Month 1)

We mapped the full SaaS keyword landscape into four content tiers aligned with buying intent:

• High-intent commercial: "[category] software", "best [category] tools" — high competition, long-term targets
• Comparison intent: "[competitor] alternatives", "[brand] vs [brand]" — medium competition, high conversion
• Integration intent: "[product] + [integration]" queries — low competition, high qualification signal
• Use-case informational: "how to [solve problem with product]" — builds topical authority and pipeline

Phase 2: Content Programme (Months 2–8)

• 22 competitor alternative pages (e.g., "Best [Competitor] Alternatives in 2025") — average conversion rate: 4.8%
• 35 integration pages covering every major tool connection — captured 1,400 monthly searches
• 18 use-case pillar pages with supporting cluster content
• 40 long-form guides targeting informational queries across the category

Phase 3: Link Acquisition (Months 3–12)

• 42 editorial placements on SaaS review publications, tech media, and business software blogs
• 6 data-driven studies shared with tech journalists — earned coverage in 3 mainstream business publications
• Product Hunt and SaaS directory listings to build referral and brand signals

Results After 12 Months

• +320% organic trial signups — from 140/month to 588/month via organic search

• 1,200+ keyword rankings on page one across comparison, integration, and informational intent
• Competitor alternative pages became the highest-converting pages on the site at 4.8% trial signup rate
