The landscape of web searches is constantly changing, and with those changes comes the need for continued optimization of web content. Without meaningful updates to your content or site, you’re less likely to appear in search results, meaning no one will be able to find your business.
The biggest change to search engine results in recent years is the rise of AI-generated summaries that compile relevant, trustworthy sources related to a query. Being cited by these summaries is a great way to gain visibility, and this has led to the development of a new strategy called AI optimization (AIO). If you’re in need of AIO assistance, there are dozens of agencies out there who can offer you guidance. But how do you know which ones are reputable or best for you?
That’s where we come in! Check out the guide below for all the info you need on how to pick an AIO agency that can take your visibility to the next level!
How We Ranked the Best AIO Agencies
AIO can be a complex field to navigate. Various agencies, including companies experienced in more traditional search engine optimization (SEO), now offer assistance to businesses that need to optimize their content and brand for AI retrieval. Not every agency is the same, however, and not all of them are actually good at what they claim to do.
Selection Criteria
When we took a look at some of the biggest AIO agencies out there, there were a few things we looked for. Here are some of the criteria that make an AIO agency likely to offer excellent service:
- Clear methodology for improving AI visibility
- Key tracking metrics (i.e., citations, mentions, share of voice, prompt coverage)
- Strong technical SEO and on-page capability
- AI-friendly content strategy focused on structure, retrieval, and intent coverage
- Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T)
- Authority building procedures to establish brand footprint, PR, and credible links
- Proven thought leadership, case studies, experiments, and frameworks
- Clear deliverables and realistic expectations

What Is AIO?
Before we get into the list of agencies you can pick from to help you with AIO, it’s important to understand exactly what AIO is. AIO, or AI Optimization, is the process by which you improve your brand or content in such a way that it is more likely to be referenced as a reliable source by AI-generated search results, such as summaries generated by Google AI or ChatGPT.
AIO, when practiced correctly, reformats and improves a brand’s content or online presence so that it is more appealing to AI Overviews, which automatically respond to a user’s query when it is submitted to a search engine, reviewing potential sources in milliseconds and compiling a trustworthy answer to the query based on which sources the AI deems to be most reliable.
How To Choose a Good AIO Agency
AIO can be overwhelming to start out with, but it doesn’t have to be a chore. Choosing a good agency comes down to a few simple factors. Here are a few general tips that you can follow to pick the best agency for your business:
- Terminology: A good AIO agency will clearly define what they mean by AIO and what outcomes they target. They’ll offer you a clear focus to guide your AIO strategy and won’t hide the technical details from you.
- Expertise: Any good AIO agency should be able to show you exactly how they design content to be selected and cited. Ask them about their process and look for specific details about how they create content, such as structures, features, keywords, internal linking, and other key elements.
- Implementation: A strong AIO agency can implement or guide schema and page structures. There should never be any guesswork involved in your optimization process. While experimentation is perfectly fine, you should never feel like your AIO agency does have a clear plan or reason to believe their strategies will succeed.
- Track Record: Naturally, all reputable AIO agencies will be able to refer back to experience they have in markets with entrenched incumbents. You should be able to get them to tell you about previous or existing clients, their success stories, and examples of how their AIO strategies resulted in growth.
- AI-Specific Tracking: A good AIO agency can quantify your performance on various AIO KPIs. They will be able to track and provide clear numbers in regards to your brand’s citations, mentions, and prompt coverage over time, allowing you to interpret data and develop your strategy as things change.
Signs To Avoid an AIO Agency
When ranking the best AIO agencies, we also compiled several different red flags that you should keep an eye out for when you’re looking for a good agency. In general, we found that disreputable AIO agencies frequently claimed to sell “AI tools,” not dedicated optimization services
In general, bad AIO agencies push mass AI content output without a retrieval strategy, focusing on quantity over quality. They may offer no discernible measurement plan beyond keyword rankings, and they will likely have no authority or PR plan to build trust signals.
Conclusion
In today’s world, AI is the new frontier of search engine optimization. The companies that best adapt their brands and content to AI engines become trusted sources for millions of users around the world, and you can’t afford to be left in the dust. To take your AIO to the next level, you need the help of an agency with proven experience, execution depth, and tracking ability. Of those we’ve highlighted here, Zupo is your best bet for a comprehensive AIO service that can revolutionize the way your company does business in the online world.
