AI visibility: Features, Prompts, Topics

Semrush AI Toolkit AI visibility Features

Semrush AI Toolkit runs on a database of roughly 239M+ prompts, a mix of real search queries and AI-generated questions, monitored across 4 platforms: ChatGPT, Google AI Overviews, Perplexity, and Gemini. Prompt data refreshes daily, the Visibility Overview updates monthly, and everything is scoped to the domain you configure. Each additional domain is a separate $99/month subscription. Visibility history accumulates from the day you start tracking.

The Visibility Overview will show you if the source is YouTube or other social media, but you don’t have a dedicated section showing the deeper data layer to do the proper investigation.

AI Visibility Gauge

Semrush AI visibility gauge displays your overall score benchmarked against the industry average. It is not disclosed what is taken into consideration to form your overall score other than how often your brand is mentioned across AI platforms. You can switch to per-country display and analyze the cited pages and mentions where your brand is displayed or missing.

Ahrefs Brand Radar AI Visibility Features

Ahrefs Brand Radar runs on an index of 405M+ prompts derived from real Google search demand (Ahrefs’ 110B-keyword database plus People Also Ask) monitored across 7 platforms ( ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot, Claude). Plus it tracks the social sources AI answers, namely: Reddit, YouTube, and TikTok.

The AI index updates on a monthly basis with a 90-day reporting window, web visibility data refreshes every few minutes, and nothing is scoped to a domain, you can pull up any brand, competitor, or topic, with historical data included.

AI Visibility Responses

The place to find AI answers for any competitor is definitely Brand Radar’s AI responses. It doesn’t only include data of the pre-configured competitors but of any brand, product, or even an entire category. The index shows collected data with history included.

You can split results by platform to see where each competitor beats you, filter by country and topic, then flip on the “Not mentioned” filter and open the prompt to see the exact fanout queries and cited pages where competitors appear, and you don’t.

Competitor and Gap Analysis

Semrush Competitor Research

Semrush has a dedicated Competitor Research report comparing your audience, mentions, topics, prompts, and sources against up to 4 competitors at once. The “Missing” tab shows you topics and prompts where competitors appear, but you don’t, which can help you prioritize content and spot the gaps.

Ahrefs Brand Radar’s Topics, Cited domains, Cited pages

For competitor and gap analysis, three reports do the heavy lifting. Topics clusters the prompts where you and rivals appear into demand-ranked themes, so you see which themes you’re losing, with the individual prompts prioritized by the search volume behind them. And Cited pages goes to the URL level, where you can filter to a competitor’s domain to see exactly which of their pages are used for shaping AI answers in your niche.

Prompt and topic research

Semrush’s Prompt Research

The Prompt Research tool takes any query and breaks it into niche sub-topics and specific prompts, with the brands and sources driving each answer. You can filter by Topics, Prompts, Brands, and Source domains for the specific report you want to see. The Topics show segmented themes you can write content about with the specific prompt and AI’s response.

Ahrefs Brand Radar’s Topics

Brand Radar gives you access to the database of 405M+ prompts with explorable filters that fuel the Topics report, which clusters prompts by topic. You can look at the aggregate search volumes to see which competitor brands own the topics and decide the topics to prioritize writing content about first.

You can also use the Search Queries report to see the branded mentions of your competitors across SERP and dive deeper into the SEO layer later.

Data accuracy and transparency concerns

Semrush has faced criticism for its lack of transparency regarding data sources and methodology. On the other hand, Ahrefs Brand Radar takes a more transparent approach to data collection and methodology in public.

Category	Semrush AI Toolkit	Ahrefs Brand Radar
Methodology disclosure	Limited. A mix of search data and AI-generated questions, not fully documented	Documented: real Google keywords → fed into AI platforms → responses stored
Raw data access	No. Processed insights only.	Yes. Filter by query, response, domain, entity.
Update cadence	Daily (prompts), weekly (Brand Performance), monthly (Visibility Overview)	Google AI Overviews + AI Mode continuous; ChatGPT/Perplexity/Gemini/Copilot indexes refreshed monthly with a 90-day reporting window; search demand every few days; web visibility every few minutes.

Semrush AI Toolkit’s methodology

The platform uses a combination of keywords from their search module and AI-generated questions, feeding these into major LLMs to generate data. While this approach provides broad coverage, the limited methodology disclosure has created trust issues among some users.

Critics have questioned the validity of insights, especially for smaller brands with limited LLM presence, where results can seem speculative.

Ahrefs Brand Radar’s methodology

The platform clearly documents its data sources in its help center: keywords are sourced from what people search in Google, these keywords are entered into each AI platform, and the responses are collected and stored. The tool acknowledges that personalization and model variations can affect results.

Ahrefs’ data comes from three main sources.

1. AI visibility data comes from inputting keywords from their search database into AI platforms and recording responses (updated monthly).
2. Search Demand uses their keywords index (updated every few days).
3. Web Visibility leverages their content index powered by AhrefsBot (updated every few minutes).

While the methodology provides reliable insights based on real search behavior, users should understand that monthly AI data updates mean the tool captures trends rather than real-time changes. The focus on citations and traffic metrics provides more actionable data than simple mention counting, though some mentions without citations may be missed.

Custom prompt tracking, where every Ahrefs plan includes a base quota of prompt checks, and add-on packages (available to all free and paid Ahrefs users) to extend it.
