Everything below is already live in this demo — schema markup, AI discovery files, animated reviews, local SEO structure. But the real value comes from what we build next. Not features. Results.
Already in this demo
When someone asks Google or ChatGPT "best grading company near Placerville," your Wix site doesn't exist to them. This demo includes schema markup and an llms.txt file that feeds AI systems your business info, reviews, and services — so you get cited in AI-generated answers, not just buried in page 3 of search results.
Already in this demo
The 8 FAQs on this page are wrapped in FAQPage schema. Google displays these as expandable dropdowns directly in search results — pushing every other contractor below the fold. Each FAQ is written to match exactly how homeowners search: "Do I need a grading permit in El Dorado County?"
Already in this demo
This demo has 8 location cards — Placerville, EDH, Cameron Park, Shingle Springs, Diamond Springs, Folsom, Rescue, Pollock Pines. Each one with geo meta tags. In the full build, each becomes its own page ranking for "[service] in [city]." That's 72+ keyword combinations (10 services × 8 cities) — all pointing back to you.
Already in this demo
Your Wix site shows 2 plain text quotes. This demo showcases all 16 of your recent Google reviews in a scrolling carousel with names, dates, service tags, and platform badges. Social proof is the #1 conversion factor for contractors — and your 5.0 across 51+ reviews is gold. We make it impossible to miss.
This demo is a single page. The full build is an interconnected system — every piece feeds every other piece. More pages means more keywords. More keywords means more traffic. More traffic means more calls. More calls means more reviews. More reviews means higher rankings. Here's exactly how that flywheel works for ADCO Driveline.
Search Dominance
Right now you have one Wix homepage competing for everything. In the full build, each of your 10 services gets its own dedicated page with unique content, schema markup, and local keywords. Each of your 6+ service areas gets its own page. That's 72+ unique landing pages — "custom exhaust El Dorado Hills," "driveline fabrication Placerville," "catalytic converter Cameron Park" — each one a separate entry point into your business. Your competitors are fighting over one keyword. You own dozens.
Content Authority
We publish monthly SEO content targeting the exact questions El Dorado County homeowners type into Google — "How much does grading cost in Placerville?", "What is the best driveline shop near Placerville?", "How much does a catalytic converter replacement cost near Shingle Springs." Each article positions you as the expert, earns organic traffic, and funnels readers to your quote form. Over 12 months, that's 50+ indexed pages of content working for you around the clock — without paying for a single ad.
Review Engine
After every project, an automated email sequence goes out asking for a Google review — personalized, timed for maximum response, with a direct link that opens the review form in one tap. No more hoping customers remember. Every new review strengthens your Google ranking, feeds the schema on your site, updates your review showcase, and makes the next customer more likely to call you instead of the contractor with 3 reviews. At your current project volume, you could be at 100+ reviews within a year.
Lead Capture
Right now, someone who finds you at 9pm hits a Wix page with a phone number and no form. They move on. With the full build, every page has a quote request form with service selector, project description, and contact info. An AI-powered auto-responder acknowledges the submission instantly — confirming Ken will follow up, providing estimated response time, and capturing the lead in your CRM. You wake up Monday morning to a pipeline of warm prospects, not a list of missed opportunities.
Visual Proof
When a homeowner is comparing three contractors, the one with detailed project photos showing real transformations wins. We build dedicated before-and-after galleries with interactive slider comparisons for each project type — exhaust systems, driveline fabrication, catalytic converters, differential service. Organized by service and location, tagged with descriptions, and embedded with schema so Google can surface them in image search. Your photos are already excellent. We display them in a way that converts browsers into callers.
Social Integration
Your Instagram project posts automatically appear on your website's gallery. Your website content generates Instagram captions, Google Business posts, and Facebook updates via AI. One photo of a finished exhaust build becomes a website gallery entry, an Instagram post with hashtags, a Google Business update with a call-to-action, a review request email trigger, and a portfolio piece on your service page — all from a single upload. The system multiplies your effort while Ken stays under the lift.
Video Testimonials
We add a video testimonial section where satisfied customers like Ryan, Mike, Shelby, and Dimitri can share 30-60 second clips about working with Ken. Video reviews convert 2-3x higher than text. Each testimonial gets embedded on your homepage, the relevant service page, and the area page for that customer's location. Shared on social media and syndicated to your Google Business Profile. One video works in six places at once, building trust on autopilot with zero ongoing effort from you.
AI Visibility
ChatGPT now has 800 million users. Perplexity processes 780 million queries per month. Google AI Overviews answer questions before people even click a link. When someone asks these tools "Who's the best exhaust shop near Placerville?", the answer comes from structured data, llms.txt files, schema markup, and entity-rich content — all of which this demo already has and your Wix site has none of. The full build expands this across every page, every service, every location. You don't just rank. You get recommended.
Google Business
Your Google Business Profile is your most valuable local asset — it shows up in map packs, local search, and "near me" queries. We optimize every field: categories, service descriptions, Q&A, weekly photo posts, automated review responses, and service area definitions. AI-drafted Google Posts go live weekly, keeping your profile active and signaling to Google that this is a living, active business. Most contractors set up their GBP once and forget it. Yours will be the most active profile in El Dorado County.
Reputation Management
Every Google review gets a personalized, professional response drafted by AI and queued for your approval. Positive reviews get thanked with specific details about the project. The occasional concern gets addressed promptly and constructively. Google's algorithm rewards businesses that respond to reviews — it signals engagement and customer care. Right now your reviews sit unanswered. With the full build, every single one gets a response, strengthening your ranking and your reputation simultaneously.
Platform Ownership
Your current site is rented from Wix, built by a third party, and locked to their platform. If the previous webmaster stops responding, if Wix raises prices, or if you want to add a feature they don't support — you're stuck. The full build runs on modern infrastructure you control. Your domain, your code, your customer data, your analytics. No middleman, no lock-in, no limits. When your business grows, your site grows with it — because you own it.
Analytics & Intelligence
Your Wix site has no visibility into what's working. The full build includes real-time analytics showing which pages get traffic, which keywords bring visitors, which cities generate the most leads, and which review platforms drive the most clicks. Monthly reports show ROI clearly — you'll know exactly how many leads came from the site, what they searched to find you, and which services are in highest demand. Data-driven decisions instead of guesswork.

This is what a site built for 2026 looks like, Ken.
