Our suite prioritizes 'Experience' and 'Semantic Depth' — shifting focus from raw keyword count to intent-matching and technical stability, as required by the latest Core updates. ### Can I perform a full technical SEO audit for free? Yes. Our Live SEO Analyzer and Sitemap Engine allow you to diagnose indexing blockers and hierarchy errors without a subscription. ### Is my data stored during the Live SEO Audit? No. All audits are performed as transient sessions. Your domain's technical telemetry is processed locally and never retained on our servers. ### How does the Backlink Checker find my site's backlinks? It queries public backlink data sources and analyzes your domain's referring domains, anchor text distribution, and authority scores. All analysis runs client-side, so your competitive research stays private. ### What's the difference between the SEO Analyzer and the Sitemap Engine? The SEO Analyzer audits individual pages for on-page factors (meta tags, headings, alt text, keywords) while the Sitemap Engine handles bulk indexing issues — generating sitemaps, robots.txt files, and analyzing crawl budget across your entire domain. ### Will these SEO tools help me rank better on AI-powered search like Perplexity and Google AI Overviews? Yes. Our tools specifically check for structured data, semantic markup, and authoritative citation signals that modern AI-driven search engines prioritize. The SEO Analyzer validates Schema.org implementation and the Open Graph generator ensures rich previews when your content is surfaced. --- ToolNova — https://www.toolnova.org · See https://www.toolnova.org/llms.txt for the full directory.
