LLM SEO Tools Every Marketing Agency Should Know in 2026
Clients now bring a new kind of complaint to strategy calls, usually some version of “ChatGPT recommends our competitor, not us.” An LLM SEO tool gives your agency a way to answer that with data instead of screenshots and guesswork. These platforms run real buyer prompts through AI assistants, record which brands get mentioned and cited, and track how that changes over time.
The shift is already showing up in click data. A Pew Research Center analysis of real browsing behavior found that Google users who saw an AI summary clicked a traditional result in 8% of visits, compared with 15% for users who didn’t see one. Rankings still matter, but they no longer tell the whole story. This guide covers the free reports to set up first, the paid tools worth a shortlist, and how to pick one that fits your agency.
What Does an LLM SEO Tool Actually Do?
A traditional rank tracker checks where a URL sits on a results page. AI answers don’t work that way. The same prompt can return different brands depending on the model, the user’s location, and even the day, so LLM SEO tools work by sampling: they run a fixed set of prompts on a schedule, store every response, and measure the patterns.
Most platforms cover some mix of these four jobs:
Visibility Tracking
How often a brand appears for a set of prompts, usually shown as share of voice against named competitors.
Citation Analysis
Which URLs the AI engines link to as sources, including third-party review sites, directories and forums.
Sentiment and Positioning
Whether the brand is described accurately and favorably when it does show up.
Technical Readiness
Whether AI crawlers can reach and read the pages that should be getting cited.
The researchers who coined the term Generative Engine Optimization reported that targeted content changes lifted source visibility by up to 40% in generative engine responses. They also found the effect varied a lot by subject area, which is exactly why ongoing tracking matters.
Tracking is only half the job, of course. If you want the strategy side first, our explainer on why every agency needs to offer generative engine optimization covers what you’d actually do with the data.
Start With the Free Reports You Already Have
Before you pay for anything, set up the two free data sources that come straight from the search engines. They won’t show competitor share of voice, but they are first-party numbers, and that makes them the most defensible baseline you can put in a client report.
Google Search Console + GA4
AI Overviews and AI Mode traffic, blended into Search totals, plus AI referral sessions in GA4.
Bing Webmaster Tools AI Performance
Citation counts, cited URLs and grounding queries from Copilot and Bing’s AI summaries.
Google Search Console and GA4
Google’s own documentation confirms that clicks and impressions from AI Overviews and AI Mode are counted in overall Search Console traffic. The catch is that there’s no separate filter for those AI features, so you’ll see the totals without a clean breakout. To fill the gap, build a GA4 segment for referral sessions from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com. If your tracking setup is messy, fix that first with a proper Google Analytics and Tag Manager configuration, because AI referral data is only as good as the tagging behind it.
Bing Webmaster Tools AI Performance
Microsoft introduced AI Performance in Bing Webmaster Tools as a public preview in February 2026. It shows how often a site is cited as a source across Microsoft Copilot, AI summaries in Bing and select partner integrations. It also lists which URLs were cited and the grounding queries the AI used when it retrieved that content.
There are limits. The report reflects a sample of citation activity and doesn’t include click data. Even so, it’s one of the few places you can get citation numbers directly from the engine itself, which makes it worth connecting for every client today.
6 Paid LLM SEO Tools Worth Shortlisting
The platforms below are listed in no particular order. Pricing comes from each vendor’s pricing page as of November 2026 and changes often, so confirm the current plan limits before you commit.
1Ahrefs Brand Radar
Add-on to an Ahrefs planBrand Radar is built on Ahrefs’ web data and runs a very large library of search-backed prompts through AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot, storing every response. That means you can look up a prospect’s AI visibility and compare it with competitors before you’ve set up any custom tracking. A separate Prompt Tracking feature covers the specific prompts you choose to monitor.
2Semrush AI Visibility Toolkit
$99/monthThe toolkit has no free trial. It includes an AI visibility score, competitor comparisons, prompt research with volume and intent data, sentiment analysis, daily prompt tracking, and an AI search site audit that flags issues blocking AI crawlers. Semrush’s documentation names ChatGPT and Google AI Mode as tracked platforms.
The base plan’s limits are tight for agencies. You get one project and 25 tracked prompts, and extra prompts are sold as add-ons, so price it against your full client roster rather than a single account.
3Profound
Free 7-day trial, then customProfound is aimed at large brands. Its Enterprise plan tracks up to nine answer engines and adds SSO, SOC 2 compliance and dedicated support. Agent Analytics ties AI-sourced traffic back to your domains through integrations such as Cloudflare, Vercel, WordPress and Google Analytics. The free trial covers 50 prompts across ChatGPT, Gemini and Google AI Overviews, and there’s a dedicated agency plan built around per-client workspaces.
4Peec AI
From $95/monthPeec AI publishes clear pricing: Starter at $95 per month, Pro at $245 and Advanced at $495, with custom Enterprise plans that track up to 13 models. Coverage on the lower tiers includes ChatGPT, Google AI Mode, AI Overviews, Copilot and Gemini depending on the plan. Its agency bundles let you manage several client projects under one account with centralized billing.
5Otterly.AI
From $29/monthOtterly.AI has the lowest entry point on this list. The Lite plan is $29 per month for 15 prompts, Standard is $189 for 100 prompts and Premium is $489 for 400. Every plan tracks ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, while Claude, Google AI Mode and Gemini are paid add-ons. Plans include unlimited team members and GEO page audits, and Standard adds a Looker Studio connector for client dashboards.
6Scrunch
From $250/monthScrunch focuses on how AI platforms describe a brand, not just whether they mention it. The Core plan monitors ChatGPT, Perplexity, Google AI Overviews and Copilot. Enterprise expands coverage to nine models, including Claude, Gemini, Meta AI, Google AI Mode and Grok. Scrunch also runs a dedicated agency program.
LLM SEO Tool Comparison at a Glance
Here’s how the options stack up on the details agencies usually ask about first.
| Tool | Starting Price | AI Engines Tracked | Best Agency Fit |
|---|---|---|---|
| Google Search Console + GA4 | Free | AI Overviews and AI Mode (blended into Search totals) | Baseline for every client |
| Bing Webmaster Tools AI Performance | Free (public preview) | Microsoft Copilot, Bing AI summaries, select partners | First-party citation data |
| Ahrefs Brand Radar | Add-on to an Ahrefs plan | AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, Copilot | Market research, audits and pitches |
| Semrush AI Visibility Toolkit | $99/month | ChatGPT and Google AI Mode | Teams already working in Semrush |
| Profound | Free 7-day trial, then custom | Up to 9 answer engines on Enterprise | Enterprise clients |
| Peec AI | $95/month | Varies by plan, up to 13 models on Enterprise | Multi-client workspaces |
| Otterly.AI | $29/month | 4 engines included, 3 more as add-ons | Low-cost pilot programs |
| Scrunch | $250/month | 4 on Core, 9 on Enterprise | Brand perception across many models |
Prompt limits matter more than the headline price. Multiply your client count by the prompts you’d track per client and the engines you need, then compare the real monthly cost. A $29 plan and a $250 plan can end up much closer than they look.
How to Choose the Right LLM SEO Tool for Your Agency
Client demand for this work isn’t going away. Stanford’s 2026 AI Index reports that organizational AI adoption reached 88%, so your clients’ own teams are using these assistants daily and will expect you to explain how their brand shows up.
Use these six criteria to narrow your shortlist:
- Engine coverage: match the tool to where each client’s buyers search. A local service business needs AI Overviews and AI Mode, while a B2B software client may care more about ChatGPT, Copilot and Perplexity.
- Prompt economics: calculate the cost per tracked prompt across your whole roster, including add-ons.
- Client workspaces: check whether each client gets a separate project and whether extra seats cost more.
- Reporting exports: look for CSV, API or Looker Studio access so the data feeds into your monthly client reporting instead of living in another login.
- Clear methodology: ask how often prompts run, from which locations, and how responses are sampled. Vague answers here usually mean noisy data.
- Data handling: find out where client prompts and brand data are stored. The NIST AI Risk Management Framework is a useful reference for the trust and governance questions to put to any AI vendor.
The most practical test is a short bake-off. Pick two tools, load the same 20 prompts for one client, and run both for 30 days. You’ll learn quickly which one gives stable, explainable numbers and which one swings wildly from week to week. Keep in mind that AI visibility still rests on solid SEO fundamentals, a point we cover in more depth in SEO in the AI era: adapting to LLMs.
Frequently Asked Questions
What is the best LLM SEO tool?
There isn’t one best LLM SEO tool for every agency. If you already pay for Ahrefs or Semrush, their AI visibility add-ons are the easiest place to start. If you need per-client workspaces at a set price, dedicated platforms like Peec AI or Otterly.AI are usually a better fit, and Profound suits enterprise accounts.
How much does an LLM SEO tool cost per month?
Paid plans in this guide start at $29 per month and run past $500 per month for higher prompt volumes, with enterprise plans priced on request. The number of tracked prompts and AI engines drives most of the cost. Free options from Google and Bing cover the basics without any subscription.
Is there SEO for LLMs?
Yes. It’s often called LLM SEO, GEO (generative engine optimization) or AEO (answer engine optimization). The goal is to get a brand mentioned and cited in AI-generated answers, which depends on crawlable pages, clear content structure and credible third-party mentions.
Do LLM SEO tools replace traditional SEO tools?
No. AI assistants often pull from pages that already rank well in traditional search, so keyword research, technical audits and link building still matter. Think of an LLM SEO tool as an added reporting layer that shows how that work carries over into AI answers.
The Bottom Line
AI search hasn’t replaced Google, but it has changed what “visible” means for your clients. Start with Search Console, GA4 and Bing’s AI Performance report so every account has a free baseline, then add one paid LLM SEO tool that fits your client mix and budget. Agencies that can show this data clearly now will be the ones clients trust when AI answers start driving more of their pipeline.
Want AI Visibility Reporting Without Building It In-House?
Picking a tool is the easy part. The harder work is choosing the right prompts, reading the data correctly, and turning it into content and technical fixes your clients can see results from. Ruskin Consulting runs GEO and AI SEO programs as a white-label partner for marketing agencies, so you can offer AI visibility to clients under your own brand.
