Free SEO Tools That Just Work.

SEO (Search Engine Optimization) improves rankings in traditional search results like Google and Bing. AEO (Answer Engine Optimization) optimizes content for direct answers in AI assistants, voice search, and answer boxes. GEO (Generative Engine Optimization) improves how generative AI systems like ChatGPT, Perplexity, and Google AI Overviews retrieve, summarize, and cite your content.

Start with clear heading hierarchy, entity-first copy, and concise question-and-answer sections on every key page. Add valid JSON-LD structured data for your most important entities. Use descriptive anchor text on internal links and ensure AI crawlers like GPTBot and ClaudeBot are not blocked in your robots.txt.

Title tags and meta descriptions have the biggest direct impact on click-through rates and rankings. After those, focus on crawlable internal links, descriptive H1-H3 headings, structured data that matches visible content, and a clean canonical URL strategy that prevents duplicate content issues.

An `llms.txt` file tells large language models how to interpret and reference your site. It works like `robots.txt` but for AI - you declare which pages contain authoritative content, how entities should be named, and what citation format to use. PageChecks can generate and validate your `llms.txt` to make sure AI systems represent your brand accurately.

Use the AI Readiness Checker to score how well your pages are structured for LLM retrieval and citation. It evaluates heading clarity, entity signals, answer-ready formatting, and whether your content can be extracted as a direct answer. The Citation Readiness Analyzer then shows how likely AI systems are to cite your pages over competitors.

Core Web Vitals are three metrics - LCP, INP, and CLS - that Google uses as ranking signals. LCP (Largest Contentful Paint) measures loading speed, INP (Interaction to Next Paint) measures responsiveness, and CLS (Cumulative Layout Shift) measures visual stability. Poor scores can directly hurt your search rankings and user experience.

JSON-LD structured data gives search engines explicit context about your content, enabling rich results like star ratings, FAQs, breadcrumbs, and product cards. Pages with rich results typically see higher click-through rates. PageChecks can generate valid JSON-LD schemas and validate existing markup against Google's requirements.

Run your URL through the Canonical Checker to compare the declared tag against the page's final destination after redirects. It flags protocol mismatches (HTTP vs HTTPS), trailing slash drift, cross-domain conflicts, and cases where the canonical target itself is noindexed or redirected.

Use the Hreflang Generator to build reciprocal alternate link tags for each locale. Add your language-region codes and URLs, set an x-default fallback, and copy the output into your head template. The Hreflang Validator can then verify the full cluster works across live pages.
