What is SEOizm?
SEOizm is a practical system for search visibility. You use free SEO tools to check titles, meta descriptions, headings, schema, and writing clarity. The goal is simple: help people, search engines, and AI answer engines understand your pages without guesswork. Each tool is small on purpose so you can fix one problem at a time.
Unlike heavy dashboards, SEOizm keeps the workflow short. Paste a URL or text, read the score, apply the tip, and move on. That keeps SEO tools useful for busy marketers, founders, and developers.

Four principles, one craft
Modern visibility is not only rankings. It is how clearly machines parse entities, intent, and answers.
SEO — Search Engine Optimization
Technical access, relevance, and authority matter. Keep pages crawlable. Use clear titles. Add internal links that help people move through your topic.
NLU — Natural Language Understanding
Write so systems grasp meaning. Name entities clearly. Define terms early. Show topical relationships instead of stuffing keyword lists.
NLP — Natural Language Processing
Structure language for analysis. Use clean headings. Keep terminology consistent. Prefer readable sentences and semantic markup machines can process.
GEO — Generative Engine Optimization
Lead with answers. Add FAQs and citable facts so generative engines can quote you accurately without inventing context.

Frequently asked questions
What does SEOizm check?
SEOizm checks page basics people see in Google, topic clarity, writing ease, AI-search readiness, technical setup, speed signals, accessibility, safety, trust, and domain health.
Is SEOizm really free?
Yes. The free SEO tools and website SEO checker run in your browser. You do not need an account to score a page or generate common SEO snippets.
How is GEO different from SEO?
SEO helps pages rank in classic results. GEO focuses on clear answers, FAQs, and facts that generative engines can cite without inventing context.
Do I need to install anything?
No. Open a tool, paste a URL or text, and review the results. For blocked pages, paste HTML source instead.
How often should I run Site Score?
Run it after major content edits, template changes, or relaunches. A quick re-check after fixes confirms the Basics, Topics, Writing, and AI search scores moved in the right direction.
