Free SEO Tools
A growing library of free utilities for SEO operators, growth leads, and SaaS founders, built as living proof of utility-led acquisition as a discipline.
Every tool here is engineered to be useful first and discoverable second. No email gates, no upsells. If something here saves you an hour, that’s the deal.
SEO Systems
Why this matters: why the internal link graph is a product decision
04 toolsMeta Title Generator
Writes title variants from stated patterns, then scores each on rendered pixel width, coverage of your page’s own vocabulary, and whether it duplicates a title you already have.
Schema Validator
Validate JSON-LD markup against Schema.org and Google’s structured data spec, with diff output.
NewTopical Map Generator
Build entity-mapped topical clusters from a single seed keyword in seconds, exportable to Notion or CSV.
Internal Link Mapper
Visualise your site’s internal linking flow, find authority leaks, orphan pages, and over-linked sections.
AI Search
Why this matters: what AI search actually retrieves
03 toolsAI Snippet Preview
Measures title and description in rendered pixels the way Google truncates them, and tests whether a section of your page survives being retrieved and quoted on its own.
Entity Extractor
Paste any URL or content, extract the entities your content actually signals to LLM retrieval systems.
AI Citation Tracker
A monitoring plan rather than a monitor: builds the question set, the recording sheet and the method. Querying assistants on a schedule needs a server, and everything here runs in your browser.
Content Systems
Why this matters: measuring organic when attribution breaks
03 toolsSEO ROI Calculator
Model expected ROI on SEO investment given current traffic, conversion rate, and category benchmarks.
Intent Classifier
Sorts a keyword list into four intents. Scores all four rather than stopping at the first matched rule, and flags the ambiguous ones instead of guessing confidently.
Coverage Gap Checker
Paste the pages that already rank plus your own draft. Extracts the vocabulary those pages share and shows what yours is missing.
Positioning
Why this matters: the full-stack marketer
02 toolsFounder Bio Generator
Three bio variants plus the Person schema, with a sameAs array, that makes them machine-readable. Checks your achievement line for a verifiable claim before it uses it.
Positioning Canvas
Interactive canvas to map your SaaS positioning across competitor space, category, and AI-search differentiation.
