Get cited. Get found. Get leads.
SEO, AEO, Google and Meta ads, and websites as the conversion layer — so AI cites the business, customers find it, and paid demand turns into leads.
Most agencies still sell rankings and clicks. We build AI search visibility and paid demand that turns attention into booked revenue.
Google's answer boxes and AI assistants are already deciding who gets found before a human ever clicks. 4thline.ai connects search visibility, paid demand, lead capture, and your website into one system built for that reality — engineered with the same discipline it takes to run a high-performing revenue team.

Five systems. One job: get found and booked.
SEO
Technical fixes, content architecture, and authority building so your site ranks for the searches that actually convert — not just traffic.
AEO
Answer Engine Optimization structures your content so ChatGPT, Perplexity, Gemini, Grok, and AI Overviews cite you as the answer — not a competitor.
Paid Ads
Google and Meta campaigns built around margin, not vanity metrics — every dollar tied to a pipeline outcome you can trace.
Lead Generation Systems
Automated capture, routing, and follow-up — so a lead never sits in an inbox waiting for someone to notice it.
Website Design
Fast, conversion-built sites that give SEO, AEO, and paid traffic somewhere worth landing — designed to close, not just look good.
How an engagement actually runs.
Audit & Strategy
We map your current search, ad, and lead performance against where AI-driven demand is actually moving.
Build & Launch
SEO foundations, AEO content structure, campaigns, and lead systems go live on a shared timeline — not in silos.
Optimize & Scale
Weekly signal review. Budget and effort shift toward whatever channel is actually producing booked revenue.
Report & Amplify
Clear reporting tied to pipeline, not impressions — so you always know what's working and why.
Work ethic over vanity metrics.
Revenue is the measure that matters
Rankings, impressions, and clicks are inputs. We manage toward booked revenue and pipeline, and we say so plainly when a channel isn't producing it.
Every system talks to every other system
SEO, AEO, paid, lead capture, and your website are built together so momentum in one channel compounds the others instead of sitting isolated.
Built for the AI search shift
We design for how answer engines actually surface businesses today, not the approach that worked in 2019.
Built for businesses that compete on revenue, not impressions.
From professional firms and local trades to industrial B2B and consumer brands — if a missed lead costs you real revenue and being the answer AI cites in your market matters, we're built for how you sell.
Professional firms & agencies
Legal, medical, real estate, and other expertise firms that need ChatGPT, Perplexity, and AI Overviews to cite them as the answer.
Home services & trades
HVAC, roofing, plumbing, and other service businesses where a missed call is a lost customer.
B2B, industrial & SaaS
Companies selling complex products where technical credibility and trust close the deal.
Ecommerce & consumer brands
DTC and growth-stage brands scaling paid and organic acquisition together.
