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 SEO titles from page-type formulas, measures each in pixels with a desktop and mobile preview, flags the documented reasons Google rewrites titles, and audits a whole list for duplicates and boilerplate.
JSON-LD Schema Validator
Checks every JSON-LD block on a page together: duplicate and near-identical @id values, broken references, plugin conflicts, Google eligibility as it stands today, and a repaired copy.
Topical Map Generator
Turns your own keyword list into hubs, clusters and pillars, maps them to the pages you already have, flags cannibalisation, ranks what to build first and writes the internal link plan.
Internal Link Mapper and Internal PageRank Calculator
Reads a Screaming Frog export and calculates internal PageRank, click depth, true orphans and weak anchors with navigation links set aside, then simulates the links you plan to add.
AI Search
Why this matters: what AI search actually retrieves
02 tools, 01 pausedAI Citability Checker
Scores every passage of a page on seven rules, all shown, for how well it can be quoted in AI answers, shows each passage without its heading, ranks them against your question and applies snippet controls.
Entity Extractor and Entity Gap Checker
Ranks the entities a page names by salience, with the reason for each score, compares them with up to three competitor pages for the entity gap, and builds about and mentions JSON-LD.
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 toolsSaaS SEO ROI Calculator
Forecasts SaaS SEO return with a lag and an S-curve, recurring revenue and churn, itemised cost, payback, CAC and LTV, a paid search comparison and a sensitivity chart, with every formula shown.
Search Intent Classifier
Classifies a keyword list by weighting every intent modifier, with the reason for each label, a confidence score, the page type to build, Google’s rater category, and groups of keywords that belong on one page.
Content Gap Checker
Compares your draft with two to five pages that rank for your keyword and lists the terms, phrases, sections and questions they share that you are missing, each shown in context.
Positioning
Why this matters: the full-stack marketer
02 toolsFounder Bio Generator
Turns one set of facts into ten founder bios, from an X bio to a press boilerplate, checks every achievement for a number, a name and plain wording, flags co-founder overlap and writes ProfilePage and Person schema.
NewPositioning Canvas and Competitive Positioning Map
Works through the positioning canvas, sorts your claims against competitors’ into uncontested, contested and table stakes, maps the market and drafts your positioning statement.
