Frequently asked questions

What is an SEO audit?

An SEO audit crawls your website and checks it against technical SEO best practices — broken links, redirects, canonical tags, meta data, hreflang, structured data, sitemaps, page speed and more — then reports what's hurting your rankings so you can fix it.

How much does it cost?

You start free with 1 credit on signup. When you need more, buy a one-time credit pack — Starter (50 credits, $9), Growth (150 credits, $19), or Pro (500 credits, $49). No subscription, and credits never expire. See the pricing page.

How is this different from Ahrefs or Semrush?

Those are broad suites focused on keywords and backlinks at $100+/month. Kalenux SEO Audit focuses on technical site health and PageSpeed — what's actually broken and whether you fixed it.

Do I need to verify my domain?

Yes. To crawl a site you confirm ownership with a DNS TXT record, a meta tag, or an uploaded file, so the software only audits sites you control.

How do payments and refunds work?

Checkout is handled securely by Creem, our Merchant of Record. Unused credits are fully refundable within 14 days; once you have run an audit, that purchase is final. See our refund policy and terms.
