SEO case study
The growth was real. So was the ceiling above it.
A five-month organic SEO engagement for Secusy ASV, a PCI-compliance scanning vendor, and the mid-campaign finding that changed where the effort had to go.
Engagement: April – August 2026
Focus: Organic search, technical & off-site authority

Impression growth, April → August

Monthly purchases, up every month with no gaps

Domain Authority; the real ceiling on rankings
The problem
Visibility was climbing. Rankings weren't following.
By August, Secusy ASV’s organic clicks and impressions had both grown for five straight months, the number every SEO engagement gets judged on. But two other numbers were moving the wrong way: click-through rate had fallen every single month, and average position had gotten worse, not better, even as visibility hit a new high.
More eyes on the site, weaker conversion of that visibility into rank, and clicks that combination usually gets written off as noise. Instead of moving on, I dug into why.
Running an independent domain-authority profile on secusyasv.com turned up the number that explained everything else: a Domain Authority of 4, built on just 11 referring domains. Every competitor in the same search results; PCI SSC itself, Secureframe, Adyen, Optiv, operates at a materially higher authority tier.
The causal chain ran in one direction: low authority capped how far head terms could climb against high-DA competitors, which capped click-through as impressions grew, which kept non-brand clicks flat and revenue dependent on brand searches. The falling CTR, the brand dependency, the revenue volatility, all symptoms of the same root cause.
How I solved it
Confirmed the diagnosis, then rebuilt the roadmap around it.
Before recommending anything, I checked the theory against the site’s own data. Within a single topic cluster, queries with “list” intent have lower competition, lower authority requirements, and are ranked two to four times closer to page one than the bare head terms around them. That was the clearest confirmation that authority, not content, was the bottleneck.
That confirmation changed where effort should go next. Through July and August, roughly 80% of effort had gone into content and 20% into authority-building. I rebalanced that ratio toward 60% authority work going forward: guest posts on PCI, compliance, and fintech blogs; a linkable data asset such as an annual ASV pricing report; directory listings on Capterra, G2, and Crunchbase; and outreach anchored to a new vendor-list page.
The wins
Growth held, a new channel emerged, and the ceiling got named.
Total purchases grew every month with no dips; 2 in April to 26 in August. Organic-attributed revenue was more volatile, but a new source appeared partway through: revenue from AI-assistant referrals (ChatGPT and Perplexity-style traffic), which didn’t exist in the April or May mix at all, then grew 2.5x between July and August.
