organic traffic increase in 8 months

A mid-market HRIS platform had invested heavily in product development but neglected content — resulting in near-zero organic presence despite a strong product. We rebuilt their entire content architecture around HR compliance topics and engineered their content for AI citability across ChatGPT, Gemini, and Perplexity.

Within 8 months they were ranking for 2,400+ organic keywords and being cited by 6 major AI assistants as the authority on modern HR compliance. Branded search volume grew 180% as AI-influenced users searched directly for their brand.

"Before SIGNAL, we were invisible. After 8 months, ChatGPT recommends us by name. Our pipeline from organic has tripled."

incremental revenue from AI search traffic in 12 months

An outdoor gear retailer was spending heavily on paid search but generating almost nothing from organic. Their product pages were thin, their buying guides were generic, and AI Overviews were pushing their paid ads further down the page on every major buying-intent query.

We rebuilt their content strategy around category authority — transforming product pages into expert resources and creating the most comprehensive buying guides in their category. They now rank in AI Overviews for 340+ high-intent queries and have reduced paid search dependency by 40%.

"We went from spending $120K/month on paid search to generate $400K in revenue, to generating $680K from organic alone. The ROI shift is staggering."

reduction in cost-per-acquisition over 6 months

A payments platform was generating leads from paid search at a CPA of $340 — unsustainable for their unit economics. Their account structure was fighting Smart Bidding, their attribution was broken (last-click, completely ignoring a 45-day sales cycle), and their landing pages were misaligned with ad intent.

We rebuilt the account architecture, fixed the attribution model to reflect actual sales-cycle attribution, and redesigned landing pages for the specific intent of each ad group. Within 6 months, CPA was $37. The same monthly budget now generates 9× more pipeline.

"Our previous agency told us $300 CPA was 'competitive for fintech.' SIGNAL got us to $37. I should have switched years ago."

return on total marketing investment at 18 months

A digital health platform in the chronic care space faced the most restrictive content environment in marketing: YMYL (Your Money or Your Life) content, medical accuracy requirements, and AI models that are particularly conservative about citing unverified medical sources.

We built their E-E-A-T infrastructure from the ground up — medical advisory board credentialing, research citation architecture, authoritative publication placements — then engineered their content for AI citability within these constraints. They now earn trusted-source citations in Perplexity and ChatGPT for 200+ clinical query categories.

"The healthcare AI search landscape is uniquely difficult. SIGNAL navigated it better than any agency we'd previously spoken to. The results speak for themselves."

By Industry

Results across
every vertical.

AI search marketing works differently in each industry. Here's what our methodology delivers across the sectors we know best.

312%
Avg traffic growth
B2B SaaS

Software buyers do extensive AI-assisted research before any sales interaction. GEO and Semantic SEO ensure you're cited as the recommended solution — before you've spent a single dollar on outbound.

E-Commerce

AI Overviews and LLM recommendations increasingly drive the discovery phase of product purchases. Owning these placements at the top of the funnel delivers revenue that compounds without ongoing spend.

Fintech

Financial services content faces strict accuracy and trust requirements — the same requirements that make it ideal for AI citation building. Brands that invest in genuine authority earn citations that competitors can't easily displace.

Healthcare

YMYL constraints make healthcare AI search the hardest discipline in marketing — and the most rewarding. Brands that establish genuine medical authority earn trusted-source status that is extraordinarily difficult for competitors to replicate.
