AI tools for SEO now do two jobs. The first is classic SEO work done faster: keyword research, briefs, content scoring, audits and reports. The second is new: checking whether ChatGPT, Perplexity, Gemini and Google AI Overviews mention your brand, and fixing the pages they skip. Below are 20 AI SEO tools grouped by the job they do.
Short answer. For one platform that covers classic SEO and AI visibility, start with Semrush or Ahrefs. For content optimization, use Surfer or Clearscope. For AI visibility tracking, Profound and Conductor fit enterprise teams; Otterly AI and Rankscale fit small budgets. For a free start, use Google Search Console’s Generative AI report plus ChatGPT or Claude.
Prices and plans are as listed on vendors’ sites on 27 October 2026.
What Is AI Search Engine Optimization?
AI search engine optimization (AI SEO) covers two practices: using artificial intelligence to do SEO work, and optimizing a website so AI answer engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews cite and recommend it.
The second practice goes by several names:
- GEO (generative engine optimization): getting cited inside answers that generative AI writes.
- AEO (answer engine optimization): structuring content so assistants pick it as the direct answer.
- LLMO or LLM SEO: the same idea, named after the large language models behind the answers.
The differences between these terms are smaller than the vendors’ marketing suggests. Our comparison of AEO, GEO and SEO goes through them one by one, and the GEO guide covers tactics.
More searches now show an AI answer, and the share depends on the niche. OpenAI reported 900 million weekly ChatGPT users in February 2026. BrightEdge found AI Overviews on about 48% of the queries it tracked in February 2026, up from about 30% a year earlier. In our iGaming SEO research, Google showed an AI Overview on 12.1% of gambling queries and on 77.2% of finance and health queries.
What Are AI SEO Tools?
AI SEO tools are software products that use machine learning and large language models to automate keyword research, content optimization, technical audits and reporting, and to track how often AI assistants mention or cite a brand.
SEO AI tools split into six jobs, and most teams need two or three of them:
| Job | What AI does here | Tools in this list |
|---|---|---|
| Research and competitor analysis | Clusters keywords, finds gaps, reads SERPs and competitor pages | Semrush, Ahrefs, SE Ranking, Conductor |
| Content writing and optimization | Builds briefs, scores drafts against top pages, writes first drafts | Surfer, Clearscope, Frase, MarketMuse, Writesonic, Koala AI |
| General AI assistance | Drafts, schema, regex, data analysis, ad hoc prompt checks | ChatGPT, Claude |
| AI visibility tracking (GEO) | Runs prompts in AI engines and logs mentions, citations, sentiment | Profound, Peec AI, Otterly AI, Rankscale, Scrunch, HubSpot AEO |
| Technical access for AI crawlers | Audits crawlability, renders JavaScript for bots, reads log files | Botify, Lumar, Alli AI |
| Measurement | Reports AI impressions, citations and AI referral traffic | Google Search Console, Bing Webmaster Tools, GA4 |
How We Chose These Tools
The tools are grouped by job, because a content editor and a log-file crawler solve different problems. Engine lists for trackers come from each vendor’s pricing page, which is sometimes narrower than the homepage. We preferred tools that read Search Console, analytics, crawl data or live AI answers over tools that only wrap a language model.
ICODA is a Semrush partner and runs its audits on Semrush. We also use Ahrefs, Search Console and GA4 daily, and query ChatGPT, Perplexity, Claude and Gemini directly for our studies.

All-in-One SEO Suites With AI Features
1. Semrush
Semrush is an SEO suite with a built-in AI Visibility Toolkit, so Google rankings and AI answers sit in one dashboard. We run ICODA’s keyword research and site audits in Semrush.
Key features:
- Prompt Research. Searches Semrush’s database of AI prompts by topic, with volume, difficulty and intent for each topic.
- Brand Performance. Reports share of voice, sentiment and the main narratives about your brand in Google’s AI features, ChatGPT, Perplexity and Gemini, against competitors.

- AI Search Site Audit. Shows which AI crawlers your site blocks, such as OAI-SearchBot, Google-Extended and PerplexityBot, and lists other technical blockers.
- MCP server. Connects Claude, ChatGPT or Cursor to Semrush data through MCP (Model Context Protocol, a standard that lets AI assistants pull data from other apps).
Limitations:
- Prompt tracking covers three engines; Perplexity and Gemini appear only in brand-level reports.
- The standalone AI Visibility Toolkit has no free trial, and MCP access needs Starter, Pro+ or a Classic Pro or Guru plan.
Pricing: SEO plan $139/mo. Starter with AI tracking $199/mo (50 daily prompts); Pro+ $299/mo. Standalone AI Visibility Toolkit $99/mo per domain with 25 prompts. Free tier, and a 7-day trial on the main plans.

2. Ahrefs
Ahrefs adds AI citation data to its backlink and keyword index. We use Ahrefs AI citation counts in client reporting: on the Godex SEO project, Google AI Overview citations grew from about 52 to 967 while organic traffic grew from 7,551 to 20,634 monthly visits.
Key features:
- AI citations in Site Explorer. The overview of any domain shows how many AI answers linked to it and how many of its pages were cited, on all plans.
- Brand Radar AI Visibility Index. Profiles any brand across 509 million+ monthly prompts built from Ahrefs keyword data, in AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot.

- AI Content Helper. Scores a draft from 0 to 100 on topic coverage for a chosen search intent, in English and 173 other languages.
Limitations:
- Brand Radar is a paid add-on, and the Index re-tests prompts monthly.

Pricing: Starter $29/mo, Lite $129/mo, Standard $249/mo, Advanced $449/mo, Enterprise $1,499/mo. Brand Radar custom prompts from $50/mo, AI Visibility Index from $199/mo.

Limitations:
- No public prices. The free trial is on Essentials, which has no AI search tracking; tracking starts at Growth, sold through a demo.
