Search Engine Optimization

SEO is still the foundation everything else stands on. We fix what's broken technically, build content around the searches your customers actually run, and earn the authority signals that move rankings — so organic search becomes a channel you can forecast, not hope for.

Every SEO engagement is built to feed AEO and paid media, not compete with them — the same content and technical foundation powers all three.

  • Technical SEO audit & fixes (speed, crawlability, indexing)
  • Keyword & topic mapping tied to buyer intent
  • On-page and content optimization
  • Local SEO & Google Business Profile management
  • Link building & authority signal development
  • Monthly ranking, traffic & visibility reporting
System 02 · AEO

Answer Engine Optimization

AI Overviews, ChatGPT, Gemini, and Perplexity are answering questions your customers used to type into a search box. AEO structures your content and technical markup so those systems cite your business as the answer — a new discovery layer sitting on top of traditional search.

We track not just rankings, but whether AI assistants are actually naming your business when your customers ask.

  • Structured data & schema markup for AI citation
  • FAQ & entity-based content architecture
  • AI Overview & generative search visibility tracking
  • Brand mention monitoring across AI assistants
  • Answer-first content rewrites
  • Competitive AEO gap analysis
System 04 · Lead Generation

Lead Generation Systems

Traffic doesn't matter if leads sit unanswered in an inbox. We build the automation layer that captures, routes, and follows up on every lead within minutes — CRM workflows, speed-to-lead texting, missed-call recovery, and nurture sequences that keep working after hours.

This is the system that turns SEO, AEO, and paid traffic into booked calls and closed deals instead of wasted spend.

  • CRM setup & automated lead routing
  • Speed-to-lead response workflows
  • Missed-call text-back & recovery sequences
  • Multi-channel nurture (email & SMS)
  • Pipeline stage automation & sales handoff
  • Lead-to-close dashboard reporting
System 05 · Website Design

Website Design

Your website is where every other system lands. We design and build fast, mobile-first sites with the technical architecture SEO and AEO depend on, and the layout, copy, and offers that turn a visit into a booked call.

No template theme with a logo swap — every site is built around your offer and your customer's actual decision process.

  • Conversion-focused design & copywriting
  • Fast, mobile-first build
  • SEO & AEO-ready site architecture
  • Lead capture & booking integration
  • Ongoing hosting & maintenance
  • Analytics & behavior tracking
