Project History
Allyant – Digital Accessibility Company – 5.8x SEO ROI
- 20% — Organic Qualified Leads
Before the campaign, the client was already seeing organic traffic growth, but it was not translating into enough qualified leads. Their priority was improving lead quality rather than chasing specific keyword positions, as long as SEO was generating meaningful business opportunities.
After completing the semantic and technical SEO audits, we moved into implementation. The site had significant keyword cannibalization issues, so we merged overlapping pages and optimized existing content. Combined with technical improvements, these changes helped drive more qualified leads.
In 12 months, I increased the organic share of total website traffic from 1.84% to 25.04% and boosted organic traffic engagement from 45.58% to 53.25%. The SEO campaign achieved a positive ROI of 5.8x after the first year.
Society Mortgage – US Mortgage Lender
- 3x — Increase Organic Traffic
The client had been dealing with stagnant organic traffic and relied heavily on buying leads from 3rd-party providers. Their goal was to build a sustainable organic channel that could consistently generate leads in-house.
After the SEO audit, we identified significant content gaps compared to competitors. Although the client was licensed in 30+ US states, they had no dedicated state-level pages. We also found valuable opportunities for tools such as state-specific mortgage loan calculators, which had strong search demand.
After 12 months, traffic increased severalfold and generated a consistent flow of leads. Eventually, the client stopped buying leads from third-party providers and shifted that investment into a combination of SEO and Google Ads.
Zageno – Pharmaceutical Digital Marketplace – SEO Audit
- 10% — Increase in Traffic
This unique B2B marketplace had noticed declines in rankings for certain keywords. The team suspected recent technical website updates were responsible, but they were not completely sure. They need a technical SEO expert to resolve the issues.
I conducted a full technical SEO audit using Screaming Frog, Google Search Console data, and manual checks. The audit uncovered crawlability issues affecting certain pages, as well as unresolved pagination problems.
The fixes helped recover the rankings that had previously dropped. Critical technical issues can have a significant short-term impact on SEO performance, so resolving them quickly was key to restoring visibility.
