LLM SEO services or in-house: how to decide

LLM SEO services are agencies and consultants that work to improve how a brand appears in answers from ChatGPT, Perplexity, Gemini, Claude, Copilot, and Google AI Overviews. Hire one when you lack people for off-site mention work, need results quickly across many markets, or want an outside baseline. Keep it in-house when you have SEO and content capacity, because most of the work is page quality and measurement your team already understands.

Searches for LLM SEO services grew sharply over the past year, and so did the number of agencies offering them. This page is not a list of providers; it is a decision guide for whether to buy the service at all, which parts to outsource, and what you need in-house either way. For what a good engagement should contain, see our AEO services page.

When an LLM SEO service makes sense

You have no one with SEO experience and need to start quickly. You need sustained outreach to get accurate coverage on review sites, comparisons, and industry publications, which is relationship work most product teams do not have time for. You operate in several languages or markets. Or you want an independent baseline and audit before committing your own team's time.

03

When in-house makes sense

You already have an SEO lead or content team. Your product is technical enough that outsiders struggle to describe it accurately, which is common in developer tools and B2B SaaS. Your main gaps are on your own site: missing comparison pages, vague positioning, client-side rendering. In those cases, the work is mostly SEO done carefully, and an agency would need your team's input for nearly every deliverable anyway.

04

The hybrid model

Many SaaS companies keep strategy, measurement, and on-site pages in-house, often with software for page production, and hire a specialist for digital PR and mentions. This keeps product knowledge close and buys the relationship capacity that is hardest to build internally. Agree on one prompt set and method so in-house and agency reports measure the same thing.

05

Costs to compare

For a service: retainer or project fees, plus your team's time for reviews and approvals, which is rarely zero. For in-house: salary or time allocation, an AI visibility tracker if you use one, and content production. Compare against named outputs over six months, not hourly rates. SerionFlow is an in-house option for the page component; it does not do outreach, so if mentions are your main gap, a service is the better buy.
