They research the web.
We audit your site and hand you the fix list.
Semrush is the broadest marketing research suite on the market: keywords, advertising, content, social. Its site audit is one tool among forty. Custom Web Audits is the opposite shape: a full-site audit with AI search visibility, local SEO and a plain-English fix list built in, priced per site instead of per seat and add-on.
Free score, no card. Full audits from $49 once, or $39/mo per site watched.
What we do, in one breath
One URL in. One report out: every page crawled, 13 areas scored, every finding ranked and explained in plain English, and a re-run that tells you what changed.
Technical SEO, speed, Core Web Vitals, security and email authentication, accessibility, on-page, content, backlinks and more — 13 scored areas in one report.
Whether ChatGPT, Gemini, Perplexity and Google AI Overviews mention the site, and what to change so they do. On every audit, not an add-on.
Google Business Profile, citations, map pack and what customers are actually saying, scored alongside the technical audit.
Every finding says what is wrong, why it matters and what to do, ranked by impact. No decoder ring.
Each re-audit flags what moved since the last one, including a fix that quietly broke again. Your work is provable.
White-label dashboard and branded PDF/PPTX on the Agency plan. Share links on every plan.
Side by side
Semrush is a research suite with a site-audit module inside it. We are a site audit with the research data inside it. That difference is the whole table.
| Capability | Custom Web Audits | Semrush |
|---|---|---|
| Starting price | One full audit for $49, once. A site watched continuously from $39/mo. The Agency plan with white-label and branded PDF/PPTX is $499/mo. | From about $140/mo (Pro) for one user. Extra users, the Local toolkit and the AI toolkit are each billed on top. |
| What that buys | Every page crawled, 13 areas scored, a ranked plain-English fix list, screenshots at 4 screen sizes, AI assistant visibility, local SEO and reviews, security and email authentication. All in one report. | Keyword, competitor, advertising and content research consoles with project and usage limits, plus a Site Audit tool. |
| Site audit depth | 100+ factors across 13 scored areas: technical SEO, speed and Core Web Vitals, security headers and email authentication, accessibility, on-page, content, links, local and AI. | A capable technical crawler with a site health score. Accessibility, security headers, email authentication, reviews and sentiment sit outside its scope. |
| AI search visibility | Included on every audit. Whether ChatGPT, Gemini, Perplexity and Google AI Overviews mention the site, and what to change so they do. | AI visibility is sold as a separate monthly toolkit. |
| Local SEO and reviews | Google Business Profile, citations, map pack and review sentiment, scored alongside the technical audit. | A separate Local add-on, priced per location. |
| Reports a client can read | Every finding says what is wrong, why it matters and what to do, ranked by impact. A share link on every plan. | Expert dashboards built for SEO practitioners, plus a report builder. The client-ready narrative is yours to write. |
| White-label | White-label dashboard and branded PDF/PPTX on the Agency plan. | White-label PDF reports on Guru and above. The dashboard itself stays Semrush. |
| Setup per site | Paste the URL. Connect Analytics and Search Console if you want them. Minutes, not a project ritual. | A project per site, with monthly page-crawl limits per plan. |
| Re-audits | Every re-run flags what changed since the last one, including a fix that quietly broke, in plain English. | Crawl comparison inside Site Audit. |
| Backlink and keyword research | Backlink profile and keyword data are inside each audit. It is not a standalone research console, and does not try to be. | Its core strength. One of the largest keyword databases, plus advertising and content research. |
| Pricing model | Per site. No seats, no project quotas, no add-ons for AI or local. | Per plan, with project, user and usage limits. Local and AI are paid add-ons. |

Who should pick which
Plenty of agencies run both. The honest split:
Keep Semrush if your day is…
- Keyword research with one of the largest databases
- Advertising and competitor ad research
- Content marketing and topic research toolkits
- Rank tracking at scale across many projects
Pick Custom Web Audits when you need…
- One report that audits the whole site and tells a client what to fix first
- AI assistant visibility and local SEO scored on every run, not bought separately
- A re-audit that proves the work landed
- Pricing per site, not per seat, project quota or add-on
- Your brand on the dashboard and the PDF (Agency plan)

This is what Semrush does not make: one report, every page, every finding ranked, in plain English.
