About us

We make SEO clear, safe and free for every WordPress site

RankZuno is a free WordPress SEO plugin from ToolsNest. It explains what is wrong with your site, shows every change before it happens, and lets you take it back.

Our mission

Help every website owner understand what is holding their site back, and fix it with confidence, for free.

Our story

Most SEO plugins hand you a long list of warnings and a score that feels like a promise about Google. Some change your pages without showing you exactly what will happen, and few let you take it back. Site owners end up either ignoring the warnings or making changes they do not fully understand.

We built RankZuno to work the other way around. It checks your site, explains each problem in plain language, groups problems by their cause, and tells you what to fix next. When you are ready, it shows the current and proposed value for every page, asks you to confirm, records the change, and checks again to confirm it worked. If you change your mind, you can undo it.

Who we are

RankZuno is made by ToolsNest, which builds practical tools for people who run websites. Alongside the plugin, ToolsNest runs a free SEO Academy with guides, a glossary and browser-based tools for anyone who wants to understand SEO, not just follow a checklist.

RankZuno is free software, licensed under the GPL, and it will stay free.

What we believe

The principles behind every screen

Explain, don’t alarm

Every finding says why it matters and what to do, in plain language. One setting that affects 200 pages shows up once, not 200 times.

Show before you change

Fixes show the current and proposed value for every affected page before anything is saved, and every fix can be undone.

Only count what we checked

Confirmed problems, possible problems and checks that could not run are kept apart. Our score never pretends to predict Google.

Free means free

No licence keys, accounts, limits or locked features, and no paid APIs needed.

Your data stays yours

No tracking or telemetry. Audits run on your own server and results stay in your own database.

Respect the server

Audits run in small background batches, and nothing heavy is loaded for your visitors.

How we work

Honest software, built carefully

SEO is full of big promises. We would rather be precise about what our tools can and cannot tell you.

  1. We test against real output

    RankZuno checks pages the way visitors and search engines receive them, not just what the editor says should be there.

  2. We say when we are not sure

    If a check could not run, you see why. If something might be intentional, it is marked as possible, not confirmed.

  3. We never invent numbers

    No made-up traffic, rankings, search volumes or backlink counts. Only what we can actually measure on your site.

  4. We keep you in control

    RankZuno starts in audit-only mode, never deactivates your other plugins, and asks before it changes anything.
