## Why we offer free SEO tools

We believe SEO should not be a closed field with checking tools that cost hundreds of dollars a month. Our free tools let any site owner — not just SEO professionals — audit their site against the same factors Google checks. Every tool here works without signup, without installing a plugin, and on any site on the web. They are not limited to WordPress sites, even though that is the primary audience we build for.

## Which tool, when

Free SEO audit — for an overall site sweep. SERP Preview — before publishing a new article. Schema Detector — to verify metadata. Social Preview — before sharing on social. PageSpeed — after a theme change. Hreflang Check — for multilingual sites. Headline Analyzer — when writing titles. Readability — when editing articles. WHOIS — before buying a domain. Headings — for page-structure validation.

## Getting the most from the tools

Start with the overall SEO audit to see the big picture. Then use a specific tool for each issue the audit surfaces — if there's a schema problem, run the Schema Detector. If there's a speed problem, run PageSpeed. If headings are off, run the Heading Analyzer. The tools are designed to work together: each one gives a different angle on the same big question — is my site ready to rank organically.

## What the tools do not do

These free tools give a point-in-time snapshot — they do not monitor the site continuously, alert on changes, or fix the issues themselves. There is also no historical tracking — if you wanted to compare today's PageSpeed score to last month's, there is no record. And the tools check one URL at a time — not the entire site. For wide audits (1000+ pages), a professional SEO platform is needed.

## When to upgrade to the full platform

If you manage a single site and the free tools cover your needs — great, use them whenever needed. If you manage multiple sites, want continuous monitoring, or want the platform to fix issues automatically — Rank+ is worth a look. It bundles every tool here inside a single platform that runs in the background: continuous checking, alerts when something breaks, and automatic fixing of what can be automated.

## Recommended user workflows

User 1 — a solo WordPress site owner just starting organic SEO. Workflow: Free SEO audit on the site → manual fix of critical issues → SERP Preview and Headline Analyzer for every new article → PageSpeed once a month. User 2 — a copywriter writing for 15 clients. Core toolkit: Headline Analyzer for every title, Readability Score for every article, SERP Preview before sending to the client. User 3 — an SEO agency vetting new client sites. Workflow: WHOIS to spot domain issues → SEO audit for the overall picture → Schema Detector for specific problem areas → Headings for theme bugs. Each tool collapses a workflow that would otherwise need a paid SEO platform.
