Every skill inside, with its test verdict

  1. 001

    SEO Audit Featured

    Structured technical/on-page/content SEO audit that explicitly flags a real trap: static fetch tools can't see JS-injected schema markup.

From the test bench

First-party notes from assembling and re-testing this pack — not customer reviews. Buyer feedback is published here as it comes in (reply to your purchase email to add yours).

  • ★★★★★

    SEO Audit ran a 200-page content site and its findings matched a parallel Ahrefs audit on every major item. A/B Testing flagged our own proposed experiment as underpowered, which was correct.

  • ★★★★☆

    Ad Creative and Brand Guidelines are setup verdicts: without the product-context file the 30 RSA headline variants go generic fast, and the brand config is useless until you fill it in — by design. The included product-context template exists for exactly this reason.

  • ★★★★★

    Humanizer stripped the em-dash overuse and "delve"-class vocabulary from drafts; two editors couldn't reliably flag the output as AI-assisted. The 5-email onboarding sequence shipped to a real list with normal-to-good open rates.
