Semrush is an all-in-one SEO and marketing suite: keyword research, backlink data, rank tracking, competitor research and more. Site Audit is one tool inside it. SEO Audit Hub does one part of that job, technical audits and the reporting around them, and is priced for that alone.

Where Semrush is the better choice
- You need more than an audit. Keyword research, search volumes, backlink profiles, rank tracking and competitor traffic estimates come from Semrush’s own databases. SEO Audit Hub doesn’t have a keyword or backlink index; it works from your site and from the Google and Bing accounts you connect.
- You already pay for it. If your team uses Semrush for research every day, its Site Audit is included and keeps everything in one place.
- Very large sites. Semrush’s higher tiers are built for bigger crawls than our largest plan’s 5,000 pages per audit.
Where SEO Audit Hub is the better choice
- You only need the technical audit. Paying for a full suite to use one tool is expensive. SEO Audit Hub is free for 500 pages an audit, and $19 or $49 a month after that.
- A fix list rather than a dashboard. Each failing check becomes one task with its pages and how to fix it, ranked by impact against effort, and the next audit confirms what you fixed.
- Platform-specific checks. WordPress, Shopify, headless and local business profiles add checks for the mistakes each platform tends to make.
- Client-ready output. White-label PDFs on Pro, share links without a login, viewer seats and CSV exports for developers.
Which to pick
If keyword and backlink research are part of your daily work, Semrush covers them and its audit comes along. If what you need is a dependable technical audit, a clear fix list and reports for clients, SEO Audit Hub does that at a fraction of the price, and you can try it on your own site without an account.
