What are the best free tools for AI content optimization?

These free tools are browser-based utilities for that workflow. Paste a URL or text, see results in seconds, no account required. Use one checker for a quick fix, or combine several for a full content sprint — from topic discovery and draft generation to citation scoring and technical site checks.

Key terms, explained in two sentences

GEO (Generative Engine Optimization)

The practice of structuring content so AI search engines — ChatGPT, Perplexity, Google AI Overviews — cite it when answering user questions. Not a replacement for SEO; a new layer on top.

The GEO Framework →

AI Citation

When an AI search engine names or links to your brand in an answer. Citations are the conversion event in AI search — if ChatGPT cites you, you win the query.

Citation Framework →

Citation Readiness

A score (0–100) measuring whether your page's content blocks are individually extractable by AI. Checks structure, data density, content type diversity, and technical signals.

Check your score →

E-E-A-T

Experience, Expertise, Authoritativeness, Trustworthiness — Google's framework for content credibility, adapted for AI search. AI models weigh these signals when deciding which sources to cite.

E-E-A-T Framework →

LLMs.txt

A Markdown file at your domain root that tells AI models which pages to crawl and index. Proposed in 2024 by Jeremy Howard, now the standard for AI crawler discovery.

LLMs.txt Framework →

Schema Markup

JSON-LD structured data (Article, FAQPage, HowTo, Product) that tells AI models what type of content each page contains. Helps AI understand and extract your content programmatically.

Check your schema →

AI Content Optimization

Writing and structuring content specifically for AI search engine citation — not just keyword rankings. Uses brand data, product context, and citation scoring instead of blank-prompt generation.

Optimization Playbook →

AI Brand Visibility

The percentage of tracked AI search questions that cite your brand. Improved primarily by publishing citation-ready content; optionally tracked via Brand Monitor and Dashboard after you publish.

Visibility Framework →

Free tool tips

Track category questions, not brand names. Use "best CRM for agencies" style prompts — navigational brand queries rarely surface competitors in AI answers.

Prefer buying-intent phrasing. Questions with "best", "top", "which", and "alternatives" mirror how buyers ask AI for product recommendations.

Write a direct answer intro before the first H2. Aim for 25–120 words that directly answer the reader question — models skim this block first when scoring content.

Add bullet lists for citable blocks. Structured lists and facts are easier for AI answers to quote than long prose paragraphs.

Which tool should I use first?

Start with the AI Content Checker if you have a published URL or draft to score. Use the AI Content Writer for a short free draft. Add LLMs.txt or sitemap checkers when you need site-level discovery checks.

How is the Content Checker different from Site Audit?

AI Content Checker scores a single article for topic clarity, structure, and quotable blocks — the content AI models are more likely to cite. Site Audit is an optional website checklist for technical crawlability, schema, and on-page HTML signals.

Is the free content score the same as in AI Articles?

The free checker scores clarity, brand fit, readability, structure, and quotable blocks on any URL or pasted content. AI Articles adds a publish checklist pillar (meta, word target, hero prompt) for drafts you create in the editor.

How do free tools fit into a geo content strategy?

Use the AI Content Checker and Writer to score and draft citation-ready geo content, then site checkers (llms.txt, sitemap, schema, E-E-A-T, crawlers) to confirm pages are discoverable. Sign in to save brand context and apply fixes in AI Articles — the core writing workflow.
