Which free SEO and creator tools are included?

The toolkit covers the full creator workflow in one place: technical SEO and AI-search visibility, keyword and backlink research, content and caption generation, and channel analytics — exactly 46 focused tools with permanent free access for selected tools and protected guest previews for supported Pro workflows. RankCraft SEO Page Studio turns live-page evidence into a prioritized weakness report and a complete page blueprint, while the wider workspace includes website health, indexing, robots, keyword, content and performance utilities.

How do creators get results with these tools?

Most creators follow a simple loop: audit the page, fix what the report flags, build authority, then track rankings. Each tool hands off to the next with a recommended next step, so a complete SEO round takes minutes instead of hours — and re-checks are instant thanks to built-in caching.

  1. Run the SEO Audit and fix errors first, warnings second.
  2. Check AI visibility with the AI Search Readiness Checker (AEO & GEO).
  3. Close your authority gap with the Backlink Builder's 12-week plan.
  4. Track keywords and positions in the SERP Check tab monthly.

The methods follow published best practices from Google Search Central's SEO starter guide and structured-data standards from schema.org — over 100 individual checks across the toolkit, scored 0–100 with a specific fix for every fail.

Everything is computed live from the fetched page.
