Building a self-sustaining backlink engine for a London B2B SaaS — 140 new referring domains in 6 months
A London B2B SaaS had plateaued in DR and needed authority signals to break into a category where the top three competitors all had 60+ DR. We built a research-led link flywheel that compounded month over month.

What had to change

The 90-day plan.
Linkable-asset audit
Identified four data-led content concepts the UK SaaS press would link to — including an annual State-of-Industry report and a benchmarking tool.
Research-first content
Commissioned a 1,200-respondent industry survey and published the data as a free interactive dashboard.
Digital PR outreach
Pitched to 180 UK journalists across business, fintech and HR press — secured 47 coverage hits.
Internal link redistribution
Rebuilt internal link architecture so newly-earned authority flowed to the 12 highest-converting pages.

Questions about this project.
Why is link-building still important in 2026?
Because AI answer engines retrieve from authoritative sources, and authority in 2026 is still mostly measured by editorial referring domains. The difference is that volume-based link-building (PBNs, low-quality guest posts) now actively hurts you — only earned, editorial coverage moves the needle.
How many links per month should I expect?
For a UK B2B SaaS engagement, 15–30 new editorial referring domains per quarter is realistic and sustainable. Anything dramatically higher is usually low-quality and will be discounted by Google.
Do you do digital PR or just SEO?
Both — we run digital PR as part of senior SEO retainers because the two disciplines are now inseparable for category authority.
Is HARO/Connectively still worth it?
Marginally. We use Connectively and Featured for opportunistic placements but build the bulk of UK coverage through direct pitching to named journalists.
What's the cost of a digital-PR-led SEO retainer?
From £6,500/month for a single-market engagement. Most UK SaaS clients sit between £8,000 and £14,000.
