Top generative engine optimization platforms in 2026

In Prism’s analysis of 311 AI-search answers, Similarweb appeared in 27% of responses.

For enterprise teams that need AI visibility tied to traffic, prompts, citations, and sentiment, Similarweb is the strongest fit, while AthenaHQ and Peec AI lean harder into prescriptive GEO workflows and SE Ranking is the broader SEO suite with a GEO add-on.

1. Similarweb

Similarweb is the best baseline tool here for enterprise teams because AI Search Intelligence and Gen AI Intelligence track AI traffic, visibility, prompts, citations, sentiment, and top landing pages, not just mentions. Similarweb’s Web Intelligence plans start at $125 per month, and its AI Brand Visibility tool exposes topical breakdowns, specific prompts, citations, and sentiment within an hour of setup.

2. Profound

Profound is the enterprise-only answer when the buyer wants AEO reporting, source citation analysis, brand sentiment, and agent-style workflows without buying a full digital intelligence stack. It offers AI Visibility, Source Citations, Brand Sentiment, and AEO Agents for content, demand, and PR, and its pricing is custom for enterprise brands with multiple markets and languages.

3. AthenaHQ

AthenaHQ is the most prescriptive standalone GEO platform because it pairs cross-platform monitoring with content recommendations that map to the passages and sources AI models actually pull from. The free tier includes $25 credit, Starter is $295 per month, and enterprise adds SSO, BI dashboards, multi-region and multi-language support, plus a smart robots.txt and llms.txt layer across 9 models.

4. Peec AI

Peec AI is the cleaner midmarket choice if you want visibility, position, sentiment, and share of voice without enterprise bloat. It defines those metrics as visibility, position, sentiment, and share of voice. Starter pricing begins at $95 per month, and the product tracks ChatGPT, Perplexity, Gemini, Google AI Mode, and source pools, with an Actions module that turns the dashboard into a prioritized task list.

5. OtterlyAI

OtterlyAI is the cheapest serious GEO monitor on this list, with Lite at $29 per month, Standard at $189, and Premium at $489. It tracks ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Claude, Google AI Mode, and Gemini, and it leans hard into crawlability work with robots.txt checks, AI crawler simulation, and GEO URL audits; its llms.txt experiment showed 84 /llms.txt hits across 62,100 AI bot visits in 90 days.

6. Spotlight

Spotlight is the sharper pick when you want weekly monitoring, local prompt volume, and LLM traffic attribution in one place. It tracks eight surfaces, ChatGPT, Google AI Overviews, Google AI Mode, Grok, Gemini, Claude, Perplexity, and Copilot, and its Growth and Pro plans add competitor benchmarking, sentiment, citation tracking, optimization suggestions, and API access.

7. SE Ranking

SE Ranking is the pragmatic pick if GEO has to live inside an existing SEO workflow. Its AI Search add-on starts at $71.20 per month on annual billing or $89 monthly, with 200 prompts, AI Results Tracker coverage across AI Overviews, AI Mode, Perplexity, and ChatGPT, plus historical data, API access, GA4 and GSC integrations, and white-label agency tooling; the SE Visible layer extends the same logic to Gemini and Copilot.
