SEO audit workflow

  • Monthly SaaS fees just to check on-page basics
  • Login required — your data sent to the cloud
  • No schema reader, no n-gram keyword density
  • Can’t audit competitor sites or localhost
SLOW & EXPENSIVE

What makes VLINK different

Why SEO practitioners choose VLINK ASIA

We don’t build tools for dashboards. We build tools for the moment you’re actively optimizing a page and need answers in seconds, not minutes.

Instant Audit, No Friction

SEO Tools PRO audits any open page across 16 on-page factors in under 5 seconds. No login, no URL copy-paste, no waiting.

Privacy by Design

All processing runs locally in your browser. No data leaves your machine — safe to use on client sites, staging environments and confidential projects.

Built from Real Audits

Every checklist in the Blueprint Library comes from 10+ years of live SEO deployments — not recycled blog posts or generic best-practice lists.

Practitioner-first approach

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.
