How To Choose A Generative Engine Optimization Agency

Since generative engine optimization is a new concept, it can be difficult to determine how to find an agency that might be the best fit. Here are some good ways to identify the best GEO service for your company.

Look For Agencies With A Strong SEO Background

While GEO and SEO do have their differences, agencies with an SEO background are the best positioned. GEO requires cross-function implementation such as content creation, outreach, social monitoring, competitive insights and tracking. Agencies with SEO experience will already have the infrastructure in place to support a lot of these goals.

Ensure The Agency Can Track AI Visibility

The best GEO companies will have a way of tracking your brand’s appearance in AI search. They’ll be able to track your prompts across different models such as ChatGPT, Perplexity, AI Overviews and more. This will help you understand how your brand is showing up, competitors that are winning, changes in features and insights from each engine. Good AI tracking is critical to any partnership with a GEO agency.

Ensure The Agency Has A Strong Understanding Of AI

You’ll also want to be sure that the agency you’re partnering with has a strong understanding of AI, the different models and how everything works. Optimizing for something such as Google’s AI Mode is very different from ChatGPT. They have different ways that they use for grounding, cite sources and the technical variables that determine indexing. A good GEO agency will understand the differences in models and what it takes to be successful in each.

Look For Both Content & Technical Expertise

A good GEO agency will have experience with both content strategies and technical site structure. These will both be paramount for ensuring that your brand has the best possible of appearing in AI search. Some AI search systems have technical limitations such as the inability to index JavaScript. As well, a good content strategy is also critical to understand how to create content eligible for AI results, build topical authority and define yourself as an expert to AI engines.

How Long Does GEO Take?

This depends entirely on the model that you’re optimizing for. Optimizing for models with faster indexing and more traditional SEO influences such as AIOs or ChatGPT Search will have shorter timelines (4-8 months). However, optimizing for models such as base-ChatGPT could have much longer time horizons.
