Search engine optimization isn’t just about ranking on Google anymore. Wherever there’s a search bar, there’s something to optimize, and AI platforms are becoming the new frontier. With the space advancing fast, early adopters will get a much bigger slice of the pie.
That’s why more businesses are shifting their focus to LLM SEO. The result? Better visibility and higher conversions across platforms like ChatGPT, Perplexity, and Google’s AI Overview. But because this strategy is so new, you’ll need the right team behind you. You need people who’ve been in the trenches, done the testing, and have the data to back up what works.
Is LLM SEO Worth It? Here’s What The Data Says
According to Semrush’s latest studies, traffic from LLMs is worth 4.4x more than traditional organic search visitors based on conversion rates. But take that with a grain of salt. Google still gets a LARGE CHUNK of the pie, with 93.57% of the global market share.
So, is LLM SEO worth it? The short answer is a definitive yes, especially in B2B SaaS. One of Spacebar’s clients gets around a 30% conversion rate from ChatGPT traffic.
If you’re considering tapping into this early, you’ll want to work with a team that knows exactly what they’re doing.
What Do LLM SEO Agencies Do?
To understand what LLM SEO agencies do, it helps to start with how large language models (LLMs) generate answers. Unlike humans, LLMs don’t search the web in real time or scroll through search results. They generate responses by pulling from patterns in their training data or retrieving snapshots of trusted sources.
That means how content is structured, cited, and connected matters more. LLM SEO agencies help businesses position their content to be found, understood, and recommended by AI models. Here’s what you can expect when you hire an LLM SEO agency:
- Entity Optimization: Making sure your brand, people, and products are clearly defined in structured data, databases (like Wikidata), and across the web.
- Topical Authority Building: Creating a web of interconnected, in-depth content that LLMs pull from when generating answers.
- Citations and Source Engineering: Structuring content to increase the chances of being cited by AI tools (especially for tools like Perplexity and Google).
- Data Source Optimization: Getting your content into LLM training sets by appearing in places they scrape from (like Reddit, news outlets, forums, or Wikipedia).
- Prompt Layer SEO: Testing how your brand shows up when someone asks an AI assistant about your industry, then reverse-engineering content to influence answers.
Factors to Consider When Hiring an LLM SEO Agency
Like traditional SEO, you should base LLM SEO strategies on your business, audience, and goals. Still, there are key factors you should always look for when choosing an agency:
Proven Results with LLM Platforms
Run-of-the-mill agencies will promise to do XYZ for your business to get results. But you’re not paying them to do a checklist of tasks. You’re paying for results. So, look for agencies with a proven track record—not just with LLM SEO, but with traditional SEO. Ask them questions like:
“Can you show examples of clients getting traffic or visibility through ChatGPT, Perplexity, or AI Overviews?”
Understanding of Entity SEO
Entity SEO is about optimizing your brand, product, people, and concepts so that AI search engines understand exactly who or what you are.
In short, Entity SEO is how well you contextualize what your brand is all about. For example, let’s ask ChatGPT for recommendations for the “best project management software.”
Here are the answers it gave:
LLMs don’t “rank” websites. They contextualize data and pull from entities and known relationships. Good LLM SEO agencies know how to build this context for AI platforms. They achieve this by doing the following:
- Implement structured data like schema markups
- Add Wikidata or Wikipedia entries
- Get mentions across high authority sites
- Ensure consistent NAP (Name, Address, Phone) information
- Plan an internal linking structure that defines the relationships between topics
Topical Authority Strategy
Relevant content is a significant factor in ensuring you get cited by LLMs. Ask the agency about their approach to building topical depth around your niche or services. It’s not about keyword stuffing. The agency should discuss clustering related content, internal linking, and creating comprehensive resources that AI tools can trust.
Data Source Awareness
One of the most significant differences between traditional SEO and LLM SEO is how the content gets discovered. Google crawls the web in real time. LLMs? They rely on pre-selected datasets and snapshots of trusted sources.
That means even if your site is well-optimized, it won’t matter if it’s not part of the data pool the AI is pulling from. A good LLM SEO agency understands this and builds strategies to get your content into places where LLMs learn from. This can include:
- Wikipedia and Wikidata: Commonly used for entity recognition
- High-authority blogs and news sites: Especially ones frequently cited in model training
- Forum mentions (Reddit and Quora): LLMs are often trained on conversational data
- Authoritative backlinks: From industry publications or research-based sources
- Public datasets and repositories: For technical or B2B industries

To help you make an informed decision, we’ve handpicked five agencies with a proven track record of delivering measurable results with LLM SEO.
Spacebar Collective: Specializes in B2B SaaS
B2B SaaS is one of the most competitive niches in SEO, and we’ve helped clients get big wins by sticking to the fundamentals: publishing quality content and building strong backlinks at scale. But as SEO changes, we’ve also made it a priority to stay ahead of the curve.

SOAR: Growth Through Community Marketing
SOAR asks a fundamental question: “How do you get yourself incorporated into training data?” That’s what SOAR aims to do with your business. And one of the ways they do this is through community marketing.
When people look for real answers, they often turn to platforms like Reddit or Quora, where responses come from those with firsthand experience. That authenticity is exactly what large language models look for when generating answers.
According to Semrush’s studies, community forums are the most cited domains in Google AI Overviews. So, if you want to grow through community marketing and have your brand mentioned in LLMs like Google’s AI Overviews, SOAR is an agency you should check out.
Omnius: Programmatic SEO
LLMs are more likely to cite your brand when your content is fresh, well-structured, and includes focused keywords, contextually linked across related topics. Publishing this way builds the kind of semantic authority that LLMs rely on when generating answers.
One of the most efficient ways to build that authority at scale is through programmatic SEO. For ecommerce businesses, pairing programmatic content with an LLM SEO strategy can increase your brand’s visibility across traditional search and AI-driven platforms.
Omnius is an agency worth checking out if you want to test this approach. They specialize in generating high volumes of BOFU, intent-driven pages that target specific queries with clean, structured content. The result is faster organic growth in the SERPs and LLM-sourced citations.
