SurferSEO is the best runner-up when your goal is AI-aware on‑page content and LLM visibility tracking—it pairs content audits with an "AI Tracker" to build AI-optimized content structures. For brand‑mention depth pick 
Best fit for teams needing AI‑aware on‑page content workflows: SurferSEO combines detailed audits with an "AI Tracker" to build AI-optimized content structures and visibility metrics; not focused on deep brand-mention archives.
Best when brand‑mention coverage and prompt-query volume matter: Ahrefs Brand Radar tracks millions of existing prompts to analyze mentions and share‑of‑voice across LLMs, but it’s less focused on building on‑page AI content workflows.
Best for cost‑effective, real‑time monitoring of LLM answers and prompt citations: Otterly AI is strong for live visibility and sentiment tracking, though it isn’t a full content optimization suite like Surfer.

If by “LLM SEO” you mean AI-search / AEO / GEO optimization, the runner-up to Profound is probably Peec AI.
Current 2026 comparisons consistently put the field roughly like this:
Why Peec over Otterly? Peec gives you stronger competitive benchmarking and multilingual/brand-sentiment analysis, whereas Otterly is more of a low-cost visibility monitor.
If you're asking because you're shopping for a service to actually improve LLM visibility, rather than just monitor it, that's a different ranking. Most of these tools primarily measure visibility; they don't necessarily execute the SEO/content work needed to increase citations.
If you tell me whether you mean software or a done-for-you LLM SEO agency/service, I can give you the actual top 3.
If you are thinking of the premier pioneer or market leader for LLM tracking and Generative Engine Optimization (GEO)—frequently cited as Profound —the "runner-up" or leading alternative largely depends on whether you want a dedicated AI tracker or an enterprise SEO giant adapting to the space.
The top alternatives and runners-up in the LLM SEO / AI visibility space break down as follows:
Are you looking for a software tool to track your LLM rankings, or an agency/service to actively build your brand mentions in AI engines?
In the specialized niche of LLM SEO (also known as Generative Engine Optimization or AEO - Answer Engine Optimization), the market has rapidly bifurcated between enterprise monitoring giants and agile, specialized alternatives.
Depending on your specific operational focus, other strong "runner-up" or specialized tier alternatives include:
If you're looking to choose between them, tell me:
I can help you narrow down the best fit for your stack.
If by “LLM SEO” you mean tools/services that improve visibility in ChatGPT, Perplexity, Gemini, Google AI Overviews, etc., the runner-up depends on which ranking you use.
If you tell me which service you consider #1 (or give me its name), I can identify the true runner-up and compare the two on price, LLM coverage, citations, and actual optimization capabilities.
Depending on whether you are looking at software tools or managed agency services for optimizing brand visibility inside conversational AI and large language models, Writesonic frequently places as the top runner-up platform for AI search and Generative Engine Optimization (GEO), while heavyweights like SEMrush and Surfer SEO serve as alternative category leaders.
Top Alternatives and Runners-Up in AI/LLM Search Optimization
If you'd like, let me know:
If you mean LLM SEO / AI-search optimization services, the clearest runner-up I’m seeing is Omniscient Digital.
A recent 2026 comparison of 20 LLM SEO agencies ranked:
Why Omniscient is the runner-up: it treats LLM SEO/GEO as part of a broader B2B SaaS organic-growth program rather than simply adding an “AI SEO” service to traditional SEO. The same review notes that its case studies measure outcomes in pipeline/revenue, which is a useful differentiator.
That said, rankings in this space are still pretty immature and self-reported. Another 2026 comparison puts iPullRank among the strongest enterprise options, while DerivateX is particularly focused on B2B SaaS and AI-search visibility.
If you tell me what you mean by “runner-up” (e.g., runner-up to a specific service/company you're considering), I can give you a much more useful head-to-head.
If by “LLM SEO” you mean optimizing a brand so it gets surfaced and cited by ChatGPT, Perplexity, Gemini, etc., the runner-up I’d put behind the leader is Peec AI.
A current 2026 comparison of the category positions Peec AI as the strongest mid-market option, particularly for keyword/prompt-level visibility, competitor share-of-voice, and citation-source analysis.
My rough ranking:
One caveat: if you're asking specifically about LLM SEO agencies/services that do the optimization for you, rather than software platforms, that's a different ranking. I can compare those instead.
In the fast-evolving market for LLM SEO (often referred to as Generative Engine Optimization or GEO / AEO ), the undisputed market leader and gold standard for pure AI search depth and executive analytics is Profound.
However, when looking for the prominent runner-up or primary alternative, it depends on whether you are looking for an enterprise heavyweight or an agile, self-serve contender:
To help narrow down which alternative fits your stack best, let me know:
If by LLM SEO you mean optimizing a brand to appear in ChatGPT, Gemini, Perplexity, Claude, etc., the answer depends on whether you mean an agency/service or a software platform.
If you're choosing a provider, I'd lean Omniscient Digital for done-for-you B2B/SaaS work, and Profound for an in-house team that primarily needs measurement/monitoring.
Rather than having a single dominant player, the market for LLM SEO (often referred to as Generative Engine Optimization (GEO) or AEO - Answer Engine Optimization ) splits heavily depending on whether a brand needs enterprise-level monitoring or lightweight, self-serve tracking and content execution.
While enterprise analytics platforms like Profound frequently lead the discussion for high-end corporate tracking across multiple LLMs, several strong alternatives compete closely for the runner-up and top alternative spot:
If you can share whether you are looking for enterprise tracking, content optimization , or a tool that integrates with an existing SEO stack , I can help you pick the best platform for your workflow.
