Discover SEMrush Site Audit Pricing (2026): What It Really Costs
Bottom line up front
SEMrush Pro costs $139.95/month and includes Site Audit as one module inside a full SEO platform. It runs 130+ technical SEO checks across a whole site - crawl errors, broken links, metadata - but it does not check conversion structure. A landing page that is not converting paid traffic will pass a SEMrush crawl while the real problem (headline mismatch, weak CTA, missing trust) stays invisible. Nebula checks the conversion layer for free, with a $97 one-time fix kit.

Pricing from semrush.com/siteaudit as of August 2026. Prices change - verify at semrush.com/siteaudit before deciding.
What you actually get for the price
A full SEO platform: site-wide technical audit (130+ checks), keyword research, rank tracking, competitor analysis. The Site Audit module tells you if Google can crawl your site healthily - broken links, redirects, duplicate content - not whether your landing page converts paid traffic.
When SEMrush Site Audit is still worth it
SEMrush is worth it for SEO teams managing site-wide technical health and organic growth. It is overkill - and priced like it - for a founder diagnosing one landing page's conversion problem.
The cheaper alternative: Nebula
Nebula audits any public landing page in under 2 minutes - free, no signup, no credit card. It checks 9 observable page conditions: headline message match, CTA clarity, trust evidence, above-fold structure, mobile CTA, load speed, ad signals, SEO foundations, and AI citation readiness. The audit reports those page conditions. It does not predict conversion from paid traffic. When the audit finds failed conditions, the $97 one-time repair sprint writes the exact copy, code, or config changes for your page.
