Generative engine optimization (GEO) is a cutting edge marketing service that helps companies get recommended by ChatGPT, Google Gemini, Perplexity, and other generative AI chatbots. GEO includes many marketing services, but its core techniques are SEO, content development, technical optimization, review management, social media management, and PR. To help marketing directors and business owners evaluate agencies that offer GEO, our team has evaluated 25+ agencies on their overall performance based on the following criteria:
- Notable Clients (35%): A list of the three most notable clients each agency has worked with. Although this information is not always accessible, efforts were made via provided case studies to determine whether the listed client sought help with GEO services.
- Leadership Experience Score (25%): A 1-5 score evaluating the prior experience of the agency’s leadership in (a) services closely related to GEO such as SEO and content marketing, (b) prior experience with generative AI technologies, and (c) ability to rapidly adapt marketing strategies in developing fields.
- Average Customer Review Score (20%): A 1-5 qualitative average of online customer reviews from third party sites. As review management is a core element of GEO, an agency’s online reviews speaks to both their customer satisfaction and their ability to execute on a GEO campaign.
- Founder Led (10%): Whether or not the founder of the company still maintains an executive or consulting position with the company, indicating the health of the company’s original vision.
- Median Employee Tenure (5%): While the least important factor in our analysis, employee morale (as indicated by how long they stay with the company on average) can help paint a picture of what kind of experience clients are likely to have when working with the agency.
The following table consists of the top 8 agencies, each of which scored above 80% in our analysis. In addition to their scoring information, we also provide a brief summary of their GEO approach.
