TL;DR:

  • The rise of AI Overviews, which is projected to answer 75% of searches by 2028, means traditional SEO alone is no longer sufficient for online visibility.
  • AI SEO is the specialized practice of optimizing content to be understood and cited by AI systems like ChatGPT and Google’s generative results.
  • Top agencies are setting the pace in this new landscape. They combine classic SEO with AI-driven optimization to help brands show up both in classic search results and AI answers.
  • The smartest move for 2026? Don’t go it alone. Partner with an AI SEO agency with a strong focus on E-E-A-T to build the authority that AI systems trust and cite.

AI has changed the way people search online, and the earlier we accept it, the better. A good example is the now-popular Google AI overviews, which launched in May 2024 for general users in the USA. 

This feature is typically found at the top of Google search results and provides instant, AI-generated summaries of what you’re searching for. 

It pulls information from many different sources so that you don’t have to do much deep digging.

According to McKinsey, approximately 50% of all Google searches in 2025 already have AI summaries. This number is expected to increase to exceed 75% by 2028. For users, this means fast and convenient results. For businesses, it’s a wake-up call: If you want to remain visible online, traditional search engine optimization may no longer cut it. You have to find a way to be found in AI searches, too.

The good news is that you don’t need to learn a new skill or hire another pro to make this possible. Working with an AI SEO agency that already knows the bolts and nuts of AI SEO is the best and most effective option.

That’s why we’ve put together this list of the top AI SEO agencies on the market today. It’s designed to help you adapt to this shift without the guesswork.

What is AI SEO?

Before we talk about agencies, it helps to know what AI SEO really means.

The goal of traditional SEO is for your website to rank on Google’s first page. You’d normally target keywords, build backlinks, write really great content, and then hope to land in those top spots. Seeing as how the top three organic search results on Google receive nearly 55% of all clicks, landing these spots is a really big deal. 

But that’s traditional SEO. AI SEO works differently.

AI SEO blends machine learning, natural language processing, and large language models with classic SEO foundations. 

The goal isn’t just to rank in classic search results only. It’s to make your content easy for AI systems like ChatGPT, Gemini, Perplexity, Claude, and other AI-powered search engines to understand, trust, and surface in answers.

FAQs

What is an AI SEO agency?

An AI SEO agency is basically a company that helps brands optimize their website and content so that both search engines and AI systems like ChatGPT and Google AI Overviews can find it. Unlike regular SEO agencies whose goal is to help you rank in search results, AI SEO agencies help you get found in both search results and AI answers.

Do you really need SEO and AEO in 2026?

Yes, you do. You need regular SEO to get found in search results, but you also need Answer Engine Optimization (AEO) so that AI systems can surface your content in AI answers. As more users rely on AI instead of clicking links, you need both working together.

Can AI SEO replace traditional SEO?

No. AI SEO cannot replace traditional SEO. These two optimization processes are designed to complement each other. You still need site health, backlinks, and quality UX, all elements of traditional SEO. AI SEO builds on that with machine-ready content and structures.

How do you optimize content for AI?

Start by being clear and direct. Use question-based headings in your posts. Each section should have a short and straight-to-the-point answer. Also, add E-E-A-T signals like author bios and stats to your content. AI models love citing original information.
