Audaitly vs Semrush Site Audit
Pick Semrush Site Audit if you already live in Semrush and need rule-based technical SEO checks at scale. Pick Audaitly if you audit client sites end to end and need evidence-backed judgment on UX, copy, trust, and conversion, with fixes shipped as pull requests. Many agencies run both.
The five differences that decide it.
Both tools crawl your site and report problems. What they look for, and what happens after, is where they diverge.
| Audaitly | Semrush Site Audit | |
|---|---|---|
| What it audits | Every page in a real browser, analyzed by our audit AI across UI/UX, content and copy, conversion and CTAs, SEO, performance, accessibility, forms, and compliance signals. | 140+ rule-based technical SEO checks: crawlability, indexability, hreflang, internal linking, duplicate content, and Core Web Vitals via lab data. |
| How findings work | Evidence-backed findings with screenshots, DOM references, and measurements, prioritized page by page, with AI chat to interrogate any finding. | Rule-based issue lists grouped into errors, warnings, and notices, with a site health score and links to help articles. |
| Fixes | Findings become assignable tasks with rescans to verify. GitHub Fix-via-PR opens real pull requests against the site's repository. | Explains each issue and how to fix it; implementation is entirely on your team. No task assignment or code-level output. |
| Pricing model | Credits-based plans from $99 to $799 per month, with founding members getting a third off. Invite-only as of mid-2026. | A module inside the Semrush suite, $139.95 to $499.95 per month across tiers as of mid-2026. You buy the whole suite, not the audit alone. |
| Best for | Agencies auditing client sites end to end and delivering evidence-backed reports clients can act on. | Teams already paying for Semrush that need technical SEO hygiene, rank tracking, and keyword workflows at scale. |

When is Semrush Site Audit the better choice?
Semrush Site Audit is the better choice when you already pay for Semrush and your core job is technical SEO at scale. If your team lives in rank tracking, keyword research, and backlink analysis, the audit module is effectively free capacity inside a suite you have already justified, and its 140+ checks cover technical hygiene, crawlability, hreflang, duplicate content, lab-data Core Web Vitals, thoroughly and repeatably.
It is also the right call for very large sites where you need deterministic, rule-based coverage across hundreds of thousands of URLs. Rules scale linearly; judgment does not need to be applied to every canonical tag. For that class of problem, a mature crawler inside an SEO suite is exactly the right tool, and Semrush’s is one of the best.
When is Audaitly the better choice?
Audaitly is the better choice when the deliverable is a client-site audit, not an SEO checklist. Semrush can tell you a meta description is too long; it cannot tell you the hero headline is vague, the testimonials read as fake, the pricing page buries its strongest plan, or the checkout form asks for a fax number. Audaitly renders every page in a real browser and has our audit AI judge it the way a senior reviewer would: copy, trust signals, CTAs, forms, accessibility, and the micro-details scanners have no rule for.
It also wins when findings need to survive a client meeting. Every issue ships with evidence, screenshots, DOM references, and measurements, prioritized page by page, exportable as PDF or share links. And when the client says “fix it,” findings become assignable tasks with rescans, or a GitHub pull request opened directly against the site’s repository. As of mid-2026, no rule-based auditor does that.
Can you use both?
Yes, and many agencies should. The tools barely overlap: Semrush answers “is this site technically sound and how does it rank,” while Audaitly answers “does this site actually persuade and convert the humans who land on it.” A common agency workflow is Semrush for ongoing technical SEO and rank tracking, and Audaitly for the periodic deep audit that anchors a client report, a redesign pitch, or a conversion sprint.
If budget forces a single pick, choose by deliverable: recurring SEO retainers lean Semrush, audit-driven client work leans Audaitly.
Run both on the same site. Compare the findings.
The clearest way to see the difference is side by side: your Semrush export next to an Audaitly report on the same client site.
