stacktxt makes online stores readable to AI assistants and shopping agents. We audit how your site reads to machines, then build and maintain the files and data they use.

What is AI search visibility?

How easily AI assistants can find, read, and accurately describe your business. It depends on crawler access, structured data, and content that is simple for a model to parse.

How is AI search different from traditional SEO?

Traditional search returns ranked links. AI search often gives a direct answer, so your facts need to be easy for a model to read. Good SEO still helps.

What does stacktxt improve?

Crawler access, machine-readable files, structured data, and product feeds. These make your store easier to read, but they do not guarantee citations, rankings, or sales.

Which businesses is stacktxt for?

Online stores and DTC brands on Shopify, WooCommerce, BigCommerce, Magento, or custom builds.

How do AI platforms discover and understand businesses?

It varies, and most providers do not publish the details. Many rely on crawlers that fetch pages and files directly, so access and clear structure matter.

What is agentic commerce?

Autonomous AI assistants and software agents searching, comparing, and completing purchases for customers. They need clear product data, plain policies, and checkout support.

How can businesses prepare for AI agents?

Allow the crawlers you want, publish clear product data and policies, add structured data, and offer machine-readable files and tools agents can use.

What is an llms.txt file?

A proposed standard: a Markdown file at your site root that summarizes your products, policies, and key links in plain text. No major AI provider has confirmed reading it, so we treat it as one low-cost layer alongside robots.txt, structured data, and product feeds.

Why does robots.txt matter for AI assistants?

robots.txt tells each crawler what it may fetch. Some stores block AI search crawlers such as OAI-SearchBot, PerplexityBot, and Claude-SearchBot by accident, often through old rules. Allowing the crawlers you want is the first step to being read.

What is an agentic commerce protocol?

A standardized communication method, such as ACP (Agentic Commerce Protocol) or WebMCP, that enables autonomous AI models to discover catalog items, query live inventory, verify pricing, and purchase programmatically with an online store.

What is the token penalty, and why does it hurt AI recommendations?

AI models operate on finite token budgets. Modern storefront pages often send over 50,000 tokens of nested HTML, scripts, and trackers. When an AI crawler inspects a bloated page, it may truncate the content or drop the store in favor of a competitor that serves clean, structured data.

How do shopping agents handle checkout and payment security?

Major payment networks like Stripe, Visa, and Mastercard are establishing delegated authority tokens and cryptographic session limits. These allow authorized agents to complete purchases within human-defined spending caps without exposing raw payment credentials.

How does stacktxt analyze my website?

The homepage check reads your public robots.txt, /llms.txt, and homepage. A review also covers structured schema, ARD, WebMCP, and Lighthouse.

What do I get from a check?

The homepage check shows crawler access, /llms.txt status, and how your HTML compares with its readable text. A review adds priorities and code directives for your platform.

How long does it take to see improvements?

It depends on your platform and catalog. We can confirm when our work is live. Assistants decide when to crawl and what to cite, so we do not promise a timeline.

Do you guarantee citations, rankings, or sales?

No. Assistants decide what to cite and recommend, and that can change at any time. We make your store easier to read and verify that the work is live. We report what we measured, not a promised outcome.

What happens in a review?

A Google Meet with Max and Kellen. We go through your robots.txt rules, Core Web Vitals, token bloat, and what to fix first, with code directives for your platform.

Can I get the review without a live call?

Yes. Choose the alternative time option when you book, and we will follow up by email to arrange another time or a recording.

What does each plan include?

Starter covers audits, ARD, /llms.txt, and schema. Growth adds feed optimization and weekly catalog sync. Scale adds real-time edge sync, multi-store feeds, and checkout simulation.

How do I start a plan?

Every plan starts with a review. Book a time, and we confirm fit, scope, and terms with you before any payment.

How does annual billing work?

Annual plans are billed once a year and include 2 months free: Starter is $990, Growth is $4,990, and Scale is $14,990.

Are there setup fees or minimum terms?

Starter and Growth have no setup fee and a 3-month minimum. Scale includes custom Cloudflare and Slack deployment setup on a 6-month term.

What are the catalog limits?

Starter includes 50 active SKUs, Growth includes 1,000, and Scale includes 5,000. Larger catalogs add $49 per month for each additional 1,000 active SKUs.

Do you support more than one storefront?

Yes. Each secondary domain feed adds $79 per month on Starter, $249 on Growth, and $749 on Scale. Scale includes regional currency feeds for the US, UK, EU, Canada, and Australia.

Which platforms do you work with?

Shopify, WooCommerce, BigCommerce, Magento, and custom or headless builds.

Can Shopify and WooCommerce stores support autonomous AI agents?

Yes. While default platform themes are built for human browsers, store owners can implement edge routing, optimized robots directives, Schema.org product graphs, and machine-readable feeds to make any platform legible to models.

Does optimizing for AI assistants change how human customers see my store?

No. stacktxt works at the edge and in machine-readable files. Your human customers continue to see your standard visual design, themes, and checkout flow. AI assistants and search crawlers simply receive clean, high-speed representations.

What is out of scope?

We do not redesign storefronts, write blog content, manage ad accounts, or rebuild ERP or warehouse software. We build the machine-readable layer.
