You showed up on Google for ten years. Now customers are asking ChatGPT instead.

Something pretty real happened in the last 18 months.

Customers used to type a question into Google, click two or three blue links, and one of them was you. Now they ask ChatGPT. Or Perplexity. Or they just read the AI Overview at the top of Google and never scroll. There's no click. There's just the answer.

If your business isn't in that answer, you don't exist for that customer. And here's the part most SEO agencies still aren't telling you — Google filed Patent US11354342B2, called Information Gain. It says if a page repeats what's already on the web, the page gets scored lower. So writing more blog posts that say the same thing as everyone else? That's actively hurting you now.

The fix isn't more content. It's a different kind of signal — one AI engines treat as an entity, not just another page.

It builds you a stack. Not just a website. A stack.

A "stack" is a set of interconnected properties — all built on platforms Google already trusts — that together act as one verified business entity that AI engines can read, source, and cite. You pick the keyword and the brand, G-Stacker handles the rest.

Built on Google's own platforms

Every stack gets a Google Doc, a Google Sheet, a Google Slides deck, a Google Calendar event, a Google Drive folder that ties them all together, plus a GitHub Pages authority site on top. Higher tiers add Cloudflare Sites, WordPress, Blogger, and Google Sites authority hubs.

That's not us hosting your data on our servers. Those are real Google properties in your Google account. Google indexes its own platforms in minutes, not weeks. And if you ever stop using G-Stacker, the properties stay where they are. They're yours.

Generated in your brand voice, not generic slop

When you add a brand, G-Stacker reads your website, learns the voice, looks at your competitors, and builds a Brand Differentiator Profile.

After that, every stack we generate sounds like your business — your tone, your offers, your service area, your people. And every property in the stack is materially different from the others, so you don't trip duplicate-content penalties.

Cultural and location intelligence built in

This is the part nobody else does. You set your customer demographics and your service area. G-Stacker generates imagery that actually represents the people you serve — not generic stock-photo people pointing at laptops.

That's Cultural & Location Intelligence — included on every tier, starting with Starter. On Professional, you also get Vernacular Intelligence and KMZ Geographic Maps that draw your real neighborhood polygon instead of a radius circle, so AI engines understand exactly where you operate.

Here's what the dashboard looks like.

Pick the keyword, pick the brand, watch the stack build.

About the patent — plain English.

Patent Pending — USPTO Provisional 64/028,674. Filed February 9, 2026.

Here's what it actually protects, without the lawyer language:

We figured out how to take a regular business — your brand, your services, your photos, your service area, the people you serve — and turn it into a verified entity that AI search engines can read with confidence. Not just a page they crawl. An entity.

Three pieces of that are pretty unusual.

First — cultural representation. Most AI-generated business imagery uses generic stock-style people. We let you set your actual customer demographics, and the generated imagery matches. There's no public patent on doing that as an authenticity signal. We filed one.

Second — location as a polygon. Most local SEO uses a circle around your address. We use a real neighborhood shape (KMZ polygon), because that's how a neighborhood actually works. AI engines that understand location entities read polygons better than circles.

Third — building only on platforms Google itself trusts. Docs, Sheets, Sites, Drive, Calendar, Blogger. Google indexes its own properties in minutes and treats them as authoritative because they live on google.com subdomains. Most SEO tools build off-platform and hope Google notices. We work inside the platforms Google already trusts.

What this means for you: this isn't a thing some other tool can copy next month. The specific method we use is protected.

You don't have to take our word for it.

How it works.

1

Sign in with Google

It's a Google Workspace Marketplace app. You sign in with your Google account. That gives G-Stacker permission to create Docs, Sheets, Slides, Sites, Calendar events, Drive folders, and Blogger posts in your account. Nothing leaves Google.

2

Add your brand

Click Add Brand. Drop in your business name and website. Hit AI Analyze. G-Stacker reads your site, learns your voice, looks at your competitors, and builds your Brand Differentiator Profile. Takes a few minutes.

3

Generate your first stack

Pick a target keyword — or pick an industry template (plumbing, roofing, real estate, law, restaurants, dental, contractors, automotive, beauty, home builders, marketing agencies). Hit Generate. G-Stacker builds the whole stack — every property, fully written, interlinked, indexed on Google's own platforms.

When you change a Doc, the stack updates. When you add a new service, the stack reflects it. You don't have to come back and maintain anything.

Frequently asked questions.

What does G-Stacker actually do?

G-Stacker builds a set of up to 11 interconnected properties (Google Docs, Sheets, Slides, Sites, Calendar, Drive, Blogger, plus optional Cloudflare Pages and GitHub Pages authority sites) that together act as one verified business entity AI search engines can read, source, and cite. You pick your service area and the work you do, and G-Stacker writes and publishes everything in your voice across Google's own platforms.

How much does G-Stacker cost?

Three monthly plans. Starter is $97/mo (35 stacks per month, 2 brand profiles, GitHub Pages, PDF reports, cultural and location intelligence). Professional is $497/mo (75 stacks, 5 brands, Cloudflare Pages, WordPress, Blogger, AI strategy reviews, vernacular intelligence, KMZ maps, rank tracking). Enterprise is $997/mo (150 stacks, 10 brands, Google Sites Authority Hub, GCS Evidence Hub, live RSS monitoring, API access, white-label reports). Annual billing is the same price as 10 months, so two months free.

Is there a free trial?

Yes. You get 2 free stacks to try with no credit card required. When you're ready for more, you add a card to start a 7-day free trial. Cancel anytime during the trial and you're not charged.

Does G-Stacker work with my Google Workspace account?

Yes. G-Stacker is listed on the Google Workspace Marketplace and was approved through Google's compliance and security review. You sign in with your Google account, which gives G-Stacker permission to create Docs, Sheets, Slides, Sites, Calendar events, Drive folders, and Blogger posts in your account. Everything lives inside your Google account on google.com subdomains. If you ever stop using G-Stacker, the properties stay where they are and remain yours.

Is G-Stacker's method patented?

Yes. USPTO Provisional Patent 64/028,674, filed February 9, 2026. It protects three specific methods: cultural representation imagery matched to your actual customer demographics, real neighborhood mapping as KMZ polygons instead of radius circles, and building business entities only on platforms Google itself indexes and treats as authoritative.

How does this help me get cited by ChatGPT, Perplexity, and Google AI Overview?

AI search engines weight content sourced from Google's own platforms higher than scraped third-party content because those platforms have established authority. By building your business entity on Google Docs, Sheets, Sites, Drive, Calendar, and Blogger (all of which Google indexes within minutes and treats as authoritative), your business becomes the verified entity AI engines surface when customers ask for the best plumber in a specific neighborhood or the top dentist near them.
