FAQ

Quick answers before you start

Is SEO Tools PRO really free with no paid tier?

Yes — completely free, no usage limits, no paid upgrade path. All 11 feature groups are available immediately after installing from the Chrome Web Store. No email, no credit card, no subscription required.

How are VLINK checklists different from free ones online?

Free checklists online are usually recycled best-practice lists. VLINK checklists are built from auditing real sites — each criterion maps to a specific fix, in a specific order, with a clear pass/fail condition. Built to hand off to a developer or use as a QA gate before launch.

Do these tools work for agency or freelance use?

Yes. SEO Tools PRO audits any URL including client sites, staging and localhost — no site ownership verification needed. Checklists are structured for delegation: fill in the project details, assign to a developer or VA, and use the checklist as a delivery standard.
