A GEO (generative engine optimization) audit checks whether AI assistants and AI search can find, read and recommend your business. It covers technical access (robots.txt, llms.txt, structured data), on-site answers (FAQ, pricing and service pages), third-party signals, and whether your brand is named for real buyer questions.

The one-time audit is $149 and is delivered as a written PDF within 48 hours of receiving your site URL and target buyer questions. Monthly follow-up is optional: $99, $249 or $449 per month.

25+ buyer questions, a technical check of your homepage and key pages (robots.txt rules for GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Google-Extended; llms.txt; JSON-LD for Organization, Service or Product, Offer and FAQPage), review and directory signals, and a competitor share-of-answer table. You get a top-10 fix list with ready-to-paste JSON-LD and an llms.txt draft.

A short vertical ad in the style of user-generated content (a quick hook, the problem, the product, a call to action) where no presenter's face is shown. The story is carried by product shots, on-screen text, captions and music.

$149 for one finished ad up to 30 seconds, or $399 for a pack of three ads with different angles. Each includes the hook, script, captions, licensed music and one revision round.

A product link, any product photos or clips you already have, your brand colours and logo, the claims you are allowed to make, and one or two ads you like. Delivery date is confirmed in writing in the quote.

Repetitive office work for small teams: email triage, lead intake, invoice and receipt extraction, lead scoring and routing, support ticket routing, error alerts and daily digests, built in n8n. Make and Zapier are available on request when you already use them.

Basic $60 (one workflow, one integration), Standard $150 (one custom workflow, up to three integrations), Premium $400 (a multi-workflow system with webhooks, monitoring and a handover document). Bigger systems are quoted in writing first.

Yes. Eight demo workflows are listed on the samples page. Each was run end to end in a local n8n instance with synthetic data and passed its built-in checks; none is a past client project.
