An LLM SEO agency does for AI answers what an SEO agency did for rankings: takes ownership of the outcome. Here is what that work actually involves, what Aethon ships as your LLM SEO partner, and the questions that separate real providers from rebranded content shops.
The job has three layers. Measurement: sampling your buyers’ real questions across ChatGPT, Gemini, Claude, and Perplexity and scoring your presence. Diagnosis: mapping which citations and consensus signals produce each answer. Execution: shipping the quotable content, corrected sources, structured data, and directory presence that change what the models say. Agencies that only do the first layer are trackers with account managers.
A fixed question set built from your actual sales conversations. Continuous monitoring with position-weighted share of voice. Citation maps showing which pages carry your category’s answers. Then the work itself: answer-ready pages, third-party source corrections, review strategy, and comparison content, verified by re-sampling until the answer moves. You get before-and-after screenshots, not activity reports.
LLM SEO retainers generally land in the range of a mid-tier SEO engagement. The better frame is per answer: each buying question your brand wins in AI is a recurring stream of pre-sold buyers. One changed answer on a high-intent question routinely outperforms a quarter of paid clicks.
Ask four questions. Which assistants do you cover, and how often do you sample? Can you show me why an answer looks the way it does, not just that it does? Who ships the fixes, you or us? And can you show an answer you changed for a client? Confident providers answer all four in the first call.
We watched brands buy visibility dashboards, receive the same gap report every month, and stall on execution. The dashboard was never the bottleneck; the shipping was. Aethon pairs the measurement with the muscle because that is the only version of LLM SEO that produces revenue instead of charts.
A provider that takes ownership of your visibility in large language model answers: measuring it across ChatGPT, Gemini, Claude, and Perplexity, diagnosing why answers look the way they do, and shipping the work that changes them.
Typically comparable to a mid-tier SEO retainer, with an audit first so scope reflects your actual gaps. Book a demo and we will price it against your baseline.
Citation-driven answers in Perplexity and Gemini often move within weeks of shipped fixes. Training-data effects in ChatGPT and Claude compound over months.
The foundations overlap, but the measurement and deliverables differ. Aethon runs the LLM layer alongside existing SEO programs without stepping on them.
With a live audit: your top buyer questions run through the four assistants, gaps identified, and a prioritized plan. You see the baseline before committing.
If you are asking what agencies provide LLM SEO services, the honest answer is that the field splits three ways: traditional SEO agencies that added an LLM line to the retainer, specialist boutiques that genuinely work the model and source layer, and platforms that productized the work. Judge any of them on the five criteria in our best AI SEO agencies evaluation: changed answers with evidence, question research beyond keywords, per model reporting, source level fixes and revenue attribution. Aethon is the platform option: the LLM SEO agency work product at published pricing from $199 per month, without the retainer.
Most teams searching for an LLM SEO agency want an outcome, not a retainer: being named when ChatGPT, Gemini, Claude, and Perplexity answer questions in their category. An agency bills hours to chase that outcome by hand. A platform like Aethon maps the moments that matter, tracks who gets recommended and why, and publishes the fixes as content, schema, and citations, continuously and at a published price. If you already work with an agency, Aethon gives them the visibility data and execution engine to work from, so the two are not mutually exclusive.
