Features FAQ
Common questions about what InstaRank SEO checks and how the tools work.
How many SEO audits does InstaRank SEO run?
InstaRank SEO runs 100+ individual audits across 23 categories — Technical SEO (robots.txt, sitemaps, canonical URLs, HTTP status, URL structure, mixed content, X-Robots-Tag, internal links, page speed), On-Page SEO (meta tags, content quality, keywords, E-E-A-T), Off-Page signals (backlinks, outbound links, social), and AI search optimization. Every audit runs on any URL for free.
Are all the features really free?
Yes. Every audit and tool on this page runs free, no credit card. A paid InstaRank Pro plan ($79/mo) adds saved projects, scheduled re-audits, white-label reports, and API access — but the audit itself is always free.
What's the difference between the audit and the tools?
The audit analyzes a URL you already have — it crawls your site and scores its technical, on-page, off-page, and AI-readiness health. The tools (Keyword Research and Competitor Analysis) help you plan ahead: find keyword opportunities and benchmark competitors before you publish.
Does InstaRank SEO check AI search optimization?
Yes. The LLM Optimization and Spam Score audits evaluate how ready your content is to be cited in AI answers — answer-readiness, FAQ markup, structured data, and E-E-A-T signals — so you can rank in ChatGPT, Google AI Overviews, Perplexity, Gemini, Claude, not just Google's blue links.
Can I run all the audits at once?
Yes. The full Website Audit runs every audit category simultaneously, so you get a complete 100+ point report in seconds rather than running each checker one at a time.
Do I need to install anything?
No. InstaRank SEO runs entirely in your browser — there's no extension, desktop app, or code snippet to install. Paste any URL and the audit starts immediately.
