Most GEO platforms charge $50-$500 per month. That makes sense once you’ve committed to an AI search strategy โ but it’s a tough sell when you’re still figuring out whether your brand even shows up in ChatGPT.
The good news is there are enough free tools now to run a complete GEO audit, track your AI rankings, research keywords, and identify gaps โ without spending anything. Some are fully free forever, some are free tiers of paid products, and some are traditional SEO tools that happen to be useful for GEO. (New to GEO? Start with our generative engine optimization guide for the full background.)
We’ve tested them all. Here’s what’s actually worth your time, organized by what you need to do.
Audit your AI search readiness
Before optimizing anything, you need a baseline. These tools tell you how your site currently performs in AI search.
Geoptie GEO Audit
Scans your website across six dimensions: citation readiness, content authority, technical optimization, structured data, content depth, and AI-friendliness. You get a score for each dimension plus specific recommendations. Takes about 30 seconds, no signup required.
This is the most comprehensive free audit we’ve found. Most other audit tools give you a single score โ Geoptie breaks it down into the specific factors that determine whether AI engines will cite your content.
HubSpot AI Search Grader
Evaluates how ChatGPT, Perplexity, and Gemini perceive your brand. You get a visibility score, sentiment analysis, and competitive benchmarking. HubSpot’s strength is the sentiment angle โ it doesn’t just tell you whether you appear, it tells you how AI engines describe you.
The limitation is that it’s a snapshot tool. You can’t drill into specific keywords or track changes over time. Think of it as a second opinion alongside a more detailed audit.
โ Try HubSpot AI Search Grader
Mangools AI Search Grader
Checks your brand across ChatGPT, Perplexity, DeepSeek, Claude, and Grok. Gives you a visibility score and basic competitive comparison. Covers more AI engines than HubSpot, though the analysis is less detailed.
Best if you want a quick cross-platform check. It takes 30 seconds and gives you a clear pass/fail sense of where you stand.
โ Try Mangools AI Search Grader
Our take: Start with Geoptie’s audit for the detailed breakdown, then run HubSpot’s grader for the sentiment angle. Between the two you’ll have a thorough baseline. Once you have your scores, our AI search optimization guide walks through exactly how to improve them step by step.
Track your AI search rankings
Once you know your baseline, you need to track specific keywords. These tools show you whether your brand appears in AI responses for the queries that matter to your business.
Geoptie Rank Tracker
Tracks your visibility across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews in one report. Enter your domain, get a report showing your citation position, mention type, and which competitors appear alongside you. No signup.
Geoptie also has dedicated trackers for individual engines โ useful when you want to understand platform-specific behavior:
- ChatGPT Rank Tracker โ tracks GPT-4o, GPT-5, and ChatGPT Search (see also: how to rank on ChatGPT)
- Perplexity Rank Tracker โ checks whether Perplexity cites and links to your site
- Claude Rank Tracker โ monitors Claude’s brand mentions in professional contexts
Manual checking
Don’t overlook the simplest option: open ChatGPT, Perplexity, and Claude and type in your target queries yourself. It’s not scalable, but for your top 10 keywords it takes 15 minutes and gives you qualitative context that no tool captures โ like how your brand is framed, what language the AI uses, and whether the recommendation sounds positive or generic.
Our take: Geoptie’s rank tracker for on-demand checks across all engines, manual spot-checking for qualitative context.
Optimize your content for AI citations
Knowing your rankings isn’t enough โ you need to know what to fix. These tools analyze your actual content and tell you how to make it more citation-worthy.
Geoptie Content Checker
Evaluates a specific page across six dimensions designed for AI search performance. Unlike the audit tool (which scans your whole site), the content checker analyzes individual URLs and tells you what to change. It scores content structure, depth, readability, authority signals, and citation-worthiness โ the same factors that determine whether AI engines cite you across ChatGPT, Perplexity, and Google AI Overviews (see AEO vs GEO vs SEO for how these citation factors differ by platform).
The page-level focus is what makes this useful. You can take your most important blog post, run it through, and get a specific list of improvements rather than generic advice.
Google’s Rich Results Test
Not a GEO tool specifically, but structured data is one of the strongest signals for AI citation. Google’s Rich Results Test validates whether your schema markup is correctly implemented and shows you exactly what structured data Google (and by extension, AI engines) can extract from your pages.
If your schema is broken or missing, AI engines have a harder time understanding your content’s entities and relationships. This is a quick, free check that most people skip.
Schema.org Validator
Complements Google’s tool by checking your markup against the full Schema.org specification, not just what Google supports. Useful for identifying structured data that might be read by AI engines even if Google doesn’t currently use it for rich results.
Our take: Run your top 5-10 pages through Geoptie’s content checker, then validate your structured data with Google’s Rich Results Test. These two steps cover the content and technical sides.
Research keywords for AI search
Traditional keyword tools like Ahrefs and Semrush are built for Google search volume. These tools focus on finding queries where AI engines generate answers โ which is a different (and increasingly important) question.
Geoptie Keyword Finder
Generates AI-optimized keyword suggestions from a seed keyword. Each suggestion comes with a GEO score indicating its AI search potential, plus data on which AI platforms return results for that keyword. This is the only free tool we’ve found that specifically scores keywords for AI citation potential rather than traditional search volume.
Google Search Console (AI Overview data)
Search Console now surfaces data on impressions from Google’s AI Overviews. Filter your performance report by “AI Overview” to see which of your pages appear in AI-generated answers on Google. This won’t tell you about ChatGPT or Perplexity, but it covers the biggest AI search surface โ Google’s own.
This is data you already have if you have Search Console set up. Most people just don’t think to check it.
AlsoAsked / AnswerThePublic
These free tools show question-based queries that people search for. Since AI engines are fundamentally question-answering machines, targeting the questions people actually ask gives your content a better chance of being cited. Neither is a GEO tool per se, but they’re useful for content planning.
Our take: Geoptie’s keyword finder for AI-specific keyword research, Search Console for Google AI Overview data you already have, and question-based research tools for content planning.
Find technical and structural issues
These tools catch problems that aren’t about content quality โ they’re about whether AI engines can access, parse, and understand your site in the first place.
Geoptie GEO Readiness Checklist
An interactive self-assessment with 30+ items across strategy, content, technical, and measurement. Check off what you’ve done, get a maturity score, see what’s missing. This isn’t an automated scan โ it’s a structured way to audit your own readiness, based on GEO best practices from industry research.
Particularly useful for SEO managers and marketing leads who need to identify blind spots before investing in tools or agencies.
Geoptie Keyword Cannibalization Checker
Identifies pages on your site that compete with each other for the same keywords. Cannibalization is an underrated problem for GEO โ when multiple pages target the same topic, AI engines get confused about which one to treat as authoritative. The more content you’ve published, the more likely this is happening without you knowing.
Geoptie Backlink Finder
Shows which websites AI engines cite most often in your industry. This is different from traditional backlink tools โ instead of showing who links to your competitors on Google, it shows which sources AI models treat as authoritative. Useful for prioritizing link building and partnership outreach.

Google Search Console
Beyond AI Overview data, Search Console shows indexing issues, crawl errors, and Core Web Vitals โ all of which affect whether AI engines can access your content. If Google can’t crawl a page, AI engines probably can’t either.
Bing Webmaster Tools
Worth setting up alongside Search Console. Bing powers parts of ChatGPT’s web-connected responses and Copilot. Bing Webmaster Tools also gives you access to IndexNow, which notifies search engines and AI systems about new content immediately rather than waiting for them to crawl it.
Putting it all together
Here’s the workflow we’d recommend using these free tools:
Step 1: Baseline. Run a GEO audit and HubSpot’s grader. Now you know your starting point.
Step 2: Track. Check your most important keywords in the rank tracker. Drill into ChatGPT and Perplexity individually. Now you know where you’re visible and where you’re not.
Step 3: Diagnose. Run your top pages through the content checker. Validate your structured data. Check for cannibalization. Now you know what to fix.
Step 4: Plan. Use the keyword finder to discover queries you’re not targeting. Check Search Console for AI Overview performance. Now you know where to expand.
Step 5: Assess. Walk through the readiness checklist. Now you know if your strategy and processes are set up to sustain this over time.
This full workflow takes about an hour using all free tools. You’ll walk away knowing your AI search visibility, what’s broken, and what to do next.
When to consider paid tools
Free tools give you on-demand snapshots and manual workflows. If you’re checking once a month or just getting started, that’s enough.
Paid GEO platforms add automated recurring tracking, historical trends, competitor monitoring dashboards, alerting when your visibility changes, and exportable reports. They make sense when AI search becomes a regular part of your marketing โ when you’re checking weekly rather than monthly, when you have multiple brands or clients to track, or when you need to report results to stakeholders.
