Honest comparison
SEMrush measures Google search; LLM Audit measures what ChatGPT, Gemini and Claude answer. How to decide which job you need done.
These tools answer different questions. SEMrush tells you how you rank in Google; LLM Audit tells you whether ChatGPT, Gemini and Claude actually name your brand when a buyer asks, and what to publish to change that. If your traffic question is Google rankings, use an SEO suite. If your question is why AI assistants recommend your competitors and not you, that is the job LLM Audit was built for, and the snapshot is free.
SEMrush is a broad SEO and online-marketing suite (keyword research, rank tracking, site audits, backlinks). It measures a different surface than LLM Audit: search-engine rankings and links rather than what AI assistants answer. Many teams need both; they are not substitutes. Verify its current AI-related features and pricing on semrush.com. LLM Audit does not claim live rankings, private customer counts, or scraped competitor performance on this page.
| Question | LLM Audit | SEMrush |
|---|---|---|
| Primary job | One-time AI visibility diagnosis plus a decision-stage publishing plan | All-in-one SEO and online-marketing suite centered on search engines |
| Free initial audit | Yes — free snapshot across ChatGPT, Gemini and Claude | Free tier and trials exist; verify current terms on semrush.com |
| Pricing (shown here) | Free snapshot; $39/mo monitoring; $99 one-time Full Report; $199/mo Agency | Subscription tiers; check current plans on the vendor site |
| AI providers measured | OpenAI (ChatGPT), Google Gemini and Anthropic Claude on every snapshot | Centered on search-engine data; verify its current AI-answer coverage directly |
| Score repeatability | Each provider is queried multiple times per audit and the score ships with an explicit X-of-N confidence signal | Rank tracking is its own methodology; AI-answer repeatability is not its core metric |
| Time to first result | Free snapshot in about a minute, with no signup, demo, or sales call | Depends on onboarding and setup of projects and keywords |
| One-time report + publishing plan | Yes — prioritized page backlog and 14-day plan | SEO audits and reports, oriented to search rankings rather than AI answers |
| Continuous monitoring | Yes — monitoring plan with score history and reruns | Yes, continuous SEO monitoring is its core |
| Shareable output | Public share link for every report, ready to send to a client or teammate without a login | Team dashboards and PDF exports; verify sharing terms |
| Best fit | Founder-led SaaS and agencies that want to go from diagnosis to shipped pages fast | Teams whose acquisition runs on Google rankings and need the full SEO toolbox |
It depends on the job. LLM Audit is designed for a fast audit and publishing plan; a broader platform may be better for ongoing monitoring or enterprise workflows.
SEMrush is worth evaluating when: you need keyword research, rank tracking, backlinks and technical SEO in one suite; Your acquisition question is Google positions, not AI answers; you already have a team working inside a full SEO workflow.
No. This comparison uses conservative positioning copy and asks buyers to verify current competitor pricing, coverage, and features independently.
A free snapshot, provider findings when configured, $39/mo monitoring with score history, an optional one-time Full Report, site evidence, and shareable report links.
Verify provider coverage, prompt methodology, pricing, update cadence, source evidence, integrations, export options, and whether the workflow creates actions your team can ship.
Yes for LLM Audit: run the free snapshot first, then unlock a one-time report for that audit.
The fastest way to make this decision concrete is to test your own brand, category, and competitors.
