Features

Everything you need for WordPress SEO, in one free plugin

Built around one idea: you should understand a problem and see the fix before anything changes.

A site audit that explains itself

34 checks across indexing, titles, links, sitemaps and structured data. Each problem says why it matters and what to do, grouped by cause instead of hundreds of warnings.

Preview, apply, undo

See the current and proposed value for every page before anything changes. Each fix is recorded, re-checked, and can be rolled back.

SEO editor with live previews

Titles, descriptions, canonical URLs, robots and social sharing in the block editor, Classic Editor and on categories, with desktop and mobile previews.

Sitemaps, robots.txt and schema

Clean XML sitemaps with accurate dates, validated robots.txt rules, and structured data for your site, articles, breadcrumbs, local business and WooCommerce products.

Redirects and 404 monitor

Permanent and temporary redirects with loop and chain protection, CSV import and export, and a 404 log that stores no IP addresses or browser details.

Internal links and easy switching

Find pages nothing links to and get link suggestions from your own content. Import from Yoast SEO, Rank Math or All in One SEO with a dry run first.

Preview before you apply

See every fix before it changes your site

Fixes open in a review window with the current value next to the proposed one. Edit any proposal, untick pages you want to leave alone, then apply. Each applied fix is recorded and can be undone from Site Audit → Change history.

  • Current and proposed values side by side
  • Character guidance for titles and descriptions
  • Undo any applied fix from the change history

  • Block editor sidebar and Classic Editor meta box
  • Desktop and mobile search result previews
  • Empty fields fall back to your title and description templates

Redirects and 404 log

Send old addresses to the right page

Add permanent, temporary or gone (410) redirects in a few clicks. RankZuno blocks loops, warns about chains and records every redirect change so it can be undone.

  • Hit counts and last-used dates for each redirect
  • A 404 log that stores no IP addresses or browser details
  • CSV import and export

Internal links

Find pages nothing links to

RankZuno reads the links inside your posts and pages, lists the content no other content links to, and suggests relevant links from your own content, analysed on your server.

  • Menu, sidebar and footer links are not counted
  • Suggestions come from your own content
  • Insert links into standard post content

How it works

How RankZuno works: from install to fixed in three steps

  1. Install and audit

    Upload the ZIP in Plugins → Add New Plugin → Upload Plugin, activate it and answer five short setup questions. The first audit runs in small background batches, so your site stays fast.

  2. Review what matters

    The dashboard answers three questions: what needs attention, why it matters, and what to fix next.

  3. Fix with confidence

    Sixteen of the 34 checks have a fix you can preview, apply and undo. For the rest, RankZuno explains what to change and where. An issue is only marked fixed when a new check confirms it.

FAQ

Frequently asked questions

What is RankZuno?

RankZuno is a free SEO plugin for WordPress. It checks your site for 34 common SEO problems, explains each one it finds in plain language, tells you what to fix next, and fixes supported problems with a preview and one-click undo.

Is RankZuno really free?

Yes. Every feature is free: no licence keys, no accounts, no usage limits and no locked "pro" features. It does not need any paid API to work.

Does the score predict my Google rankings?

No, and we say so in the plugin. The score shows how many of RankZuno’s completed checks passed, weighted by severity. RankZuno never invents traffic, ranking, search volume or backlink numbers.

Does RankZuno fix everything automatically?

No. Sixteen of the 34 checks have a fix you can preview and apply, such as writing missing descriptions, removing an unwanted noindex or redirecting a missing page. For the others, such as thin content, several H1 headings or two SEO plugins adding the same tags, RankZuno explains what to change and where, and you make the change yourself.

Can I switch from Yoast SEO, Rank Math or All in One SEO?

Yes. RankZuno imports titles, descriptions, canonical URLs, robots settings and social data for posts, plus category and tag SEO data from Yoast SEO and Rank Math, and Rank Math redirects. A dry run first shows what will be imported, skipped or is not supported: for example, Rank Math schema templates, AIOSEO global settings and the redirects in Yoast SEO Premium or AIOSEO Pro, which you can move with the CSV redirect import. Your old plugin’s data is never changed, repeated imports do not duplicate anything, and the whole import can be rolled back.

Will it change my site without asking?

No. RankZuno starts in audit-only mode and only adds SEO tags once you choose to let it. Fixes show the current and proposed values before anything is saved, and they can be undone.

Does RankZuno send my data anywhere?

No. There is no tracking or telemetry, RankZuno connects to no outside service, audits run on your own server, and results stay in your own WordPress database.
