AIO vs. SEO: What's the Difference? Costs & How to Choose

AIO vs. SEO: Which Should You Focus on Now?

In recent years, the rapid spread of generative AI, typified by ChatGPT, is significantly changing how users gather information. In Google Search, "AI Overviews" (formerly SGE) has been fully launched in the United States, shifting the search experience from the traditional "ten blue links" to one where users first see an AI-generated summary. The new web marketing method to adapt to this change is "AIO (AI Optimization)."

We are increasingly hearing from many business owners and web managers with questions like, "Is it okay to just continue with traditional SEO?" "I've heard the term AIO, but how is it different from SEO?" and "Ultimately, which one should I prioritize?"

In this article, as experts in AIO, MEO, and SEO, we will explain the following points from a neutral standpoint, without bias toward any particular service:

  • The fundamental differences in purpose and role between AIO and SEO
  • Specific comparison points such as strategies, costs, and effect measurement
  • "Common pitfalls in choosing a provider" as seen by industry professionals
  • How to choose the right strategy and priority based on your company's situation

We aim for this article to serve as a reliable basis for judgment as you formulate your company's web marketing strategy in these uncertain times.

The Roles and Goals of AIO and SEO

AIO and SEO are not conflicting concepts; they are complementary strategies that optimize for different targets. Understanding the basic role of each is the first step toward choosing the right strategy.

What Is SEO? - Optimization for "Search Engines"

SEO (Search Engine Optimization) is, as the name suggests, an optimization strategy targeting "search engines." It involves improving internal and external factors so that search engines like Google and Bing can correctly understand and highly evaluate a website's content.

  • Purpose: To maximize organic traffic to your website by ranking it higher in search results for specific keywords.
  • Target: Search engine crawlers (programs that collect information) and the algorithms that evaluate that information.
  • Main Strategies:
    • Keyword research and selection
    • Creating high-quality content that satisfies user search intent
    • Optimizing the site's internal link structure
    • Acquiring evaluations from external sites (link building)
    • Technical improvements such as site speed and mobile-friendliness (Technical SEO)
  • Metrics: Effectiveness can be measured with relatively clear indicators such as search rankings, click-through rate (CTR), organic traffic volume, and conversion numbers.

SEO can be considered the foundation of web marketing, creating a point of contact when users are actively seeking information.

What Is AIO? - Optimization for "AI"

AIO (AI Optimization) is an optimization strategy targeting "AI" (specifically Large Language Models, LLMs) like ChatGPT and Google's AI Overviews. The goal is to have your website and related information (such as your Google Business Profile) cited, referenced, or recommended as an information source when an AI generates an answer to a user's query.

  • Purpose: To increase brand awareness, reach potential customers, and ultimately drive purchasing behavior by having your services, products, or store mentioned accurately and positively in AI-generated answers.
  • Target: Large Language Models (LLMs) and their training data.
  • Main Strategies:
    • Adding semantic meaning to information through structured data markup (providing information in a format that AI can easily understand)
    • Strengthening E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) by clarifying who is providing the information and on what basis
    • Providing accurate, comprehensive factual information (company details, location, business hours, service details, etc.) and maintaining consistency
    • Expanding information on highly trusted platforms like Google Business Profile (GBP)
  • Metrics: Effectiveness often relies on indirect indicators, such as the number of citations or brand mentions in AI answers, the context of those citations, and an increase in branded searches, making measurement more complex.

AIO is positioned as a next-generation strategy to address new search behaviors where users seek information in a more conversational and summary-oriented format.

The Connection with MEO

For local businesses with physical locations, AIO is very closely related to MEO (Map Engine Optimization). MEO is a strategy focused on optimizing visibility in Google Maps.

When an AI answers a location-based question like "What are some recommended Italian restaurants near me?" it refers to Google Business Profile information as one of its most important data sources. Factors that are crucial for MEO—such as the quality and quantity of reviews, information accuracy, and the richness of photos—are directly linked to AIO evaluation. Therefore, for local businesses, AIO is best understood as an extension of MEO, or a broader concept that encompasses it.

[In-Depth Comparison] 5 Key Differences Between AIO and SEO

Now that we understand their respective roles, let's delve into more specific differences across five comparison points. This will help you decide where to invest your company's resources.

1. The Target of Optimization

The most fundamental difference is "who" you are trying to deliver the information to.

  • SEO: The target is the search engine's "algorithm." Aspects of "formal correctness" that algorithms can easily evaluate, such as page titles, heading structures, and keyword placement, are important.
  • AIO: The target is an "AI" like a Large Language Model. AI tries to understand context like a human. Therefore, the "semantic correctness" and "trustworthiness" of the information, as well as its "relevance" to other information, become more critical.

2. Specific Strategy Examples

Because the targets are different, the specific strategies also vary.

  • SEO: Often involves directly adjusting the HTML tags of a web page. For example, optimizing the `

    ` tag that indicates the page's main topic or setting the meta description that appears in search results.

  • AIO: The core task is to add "meta-information" that is invisible to humans so that AI can understand the information structurally. A prime example is implementing structured data in JSON-LD format.

For instance, to convey store information, you would embed the following code into your website. This allows the AI to understand not just a string of text, but to accurately grasp its meaning: "This is a restaurant named X, its address is Y, its phone number is Z, and its business hours are W."


<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Restaurant",
  "name": "Example-Restaurant",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "3-1-1 Sakae, Naka-ku, Nagoya-shi, Aichi",
    "addressLocality": "Nagoya-shi",
    "addressRegion": "Aichi",
    "postalCode": "460-0008",
    "addressCountry": "JP"
  },
  "telephone": "+81-52-123-4567",
  "openingHours": "Mo-Fr 11:30-14:00,17:00-22:00 Sa-Su 11:30-22:00"
}
</script>

In addition to this, strategies that guarantee the credibility of content, such as clearly stating author information and linking to primary sources, are important in AIO.

3. Differences in Measuring Effectiveness (KPIs)

There are also significant differences in how you measure the results of your strategies.

  • SEO: Using tools like Google Analytics and Search Console, you can track with considerable accuracy "what rank you achieved for this keyword, how many clicks you got, and how many people visited the site." KPIs are clear, making it easy to calculate ROI (Return on Investment).
  • AIO: The difficulty of measurement is a current challenge. There are no official tools yet to accurately measure "how many times you were cited in an AI's answer." Therefore, you need to combine indirect indicators to gauge effectiveness, such as manually monitoring mentions in AI, tracking changes in branded searches, and observing shifts in direct website traffic.

4. Typical Costs and Contract Periods

The cost of outsourcing these strategies to an external provider is another important comparison point.

  • Typical SEO Costs:
    Costs vary greatly depending on the scope of work but generally range from ¥100,000 to over ¥1,000,000 per month. Consulting on internal improvements alone is relatively inexpensive, but it becomes more costly if it includes producing high-quality content monthly or coordinating with external sites (link building). Since it takes time to see results, contract periods are typically a minimum of 6 to 12 months.
  • Typical AIO Costs:
    As this is a new field, pricing varies by provider, but it is often centered around ¥50,000 to ¥500,000 per month. The main tasks are structured data implementation and consulting. It is often offered as a set with SEO/MEO, in which case it might be an add-on to an existing contract. Contracts may be available from as short as 3 months, but continuous information maintenance is crucial. There may also be a significant initial cost for website analysis and structured data design/implementation.

5. Immediacy and Sustainability

The time it takes to see results after starting a strategy and how long those results last also differ.

  • SEO: It is generally said to take from 3 months to over a year to feel the effects. The more competitive the keyword, the longer it takes. However, once you achieve a high ranking, you can expect stable traffic, making your website a sustainable "asset."
  • AIO: Technical measures like implementing structured data may be recognized by AI relatively quickly. However, this doesn't guarantee an immediate citation in an AI's answer. The immediacy is somewhat unpredictable as it depends on the AI's learning cycles and algorithm updates. That said, once your site is recognized by an AI as a reliable source of information, it has the potential to be cited continuously, offering a sustainable effect.

How to Choose the Right Strategy and Avoid Costly Mistakes with Providers

After understanding the differences between AIO and SEO, the next steps are to determine "what my business needs right now" and "what kind of provider I should hire." Here, we present common pitfalls in choosing a provider and criteria for making decisions based on your business situation.

First, Understand Your Current Situation

The optimal strategy varies depending on your company's circumstances. Let's do a self-check on the following three points:

  1. Website Presence and Condition: Do you even have a website, or is it outdated? Are basic SEO settings (title tags, headings, etc.) in place?
  2. Physical Store Presence: Are you a business that customers visit in person, such as a restaurant, clinic, salon, or professional firm? Or are you a nationwide e-commerce site or online service?
  3. Target Customer Search Behavior: Do your customers search with specific keywords like "[product] comparison" or "how to [do something]"? Or do they ask more ambiguous questions like "recommended places for [situation]"?

[Learn from Failure] Pitfalls to Avoid When Choosing an AIO Provider

Because AIO is a new field, caution is required when selecting a provider. By learning from the mistakes many web managers have made in the past, you can avoid repeating them.

Failure Pattern 1: Providers Who Overhype, Claiming "AI Will Solve Everything"

Be wary of sales pitches like "AIO is the future. SEO is obsolete," or "Do this and AI will automatically recommend you." AIO is not a magic wand. It is effective only when built on a solid "foundation" of high-quality content established through SEO and accurate store information maintained through MEO. Implementing AIO strategies while ignoring the foundation will not lead to results.

Failure Pattern 2: Providers Whose Strategies Are a Black Box

Providers who only say, "We perform our proprietary AI optimization," without disclosing specific tasks are also risky. For structured data, the core of AIO, it is extremely important to know what types (store info, product info, FAQ, events, etc.) will be implemented and how. Before signing a contract, choose a provider who can clearly explain the specific strategies and why they are necessary for your company.

Failure Pattern 3: Providers with Vague Metrics for Success

As mentioned earlier, measuring the effectiveness of AIO has its challenges, but you cannot trust a provider who dismisses it with, "The effects are hard to see." Before signing, always confirm what key performance indicators (KPIs) they will track and how they will report on them. The key is to find a provider who demonstrates an effort to visualize results by combining alternative metrics, such as "trends in branded search volume," "Google Business Profile insights analysis," and "monitoring AI answers for specific queries."

Failure Pattern 4: Providers Lacking SEO/MEO Expertise

AIO is deeply intertwined with SEO and MEO. Much of the information that AI references ultimately comes from web pages crawled and indexed by search engines and data from Google Business Profile. AIO conducted by a provider who doesn't understand the basics of SEO/MEO will only be a superficial measure. It is crucial to determine if the provider can take a bird's-eye view of web marketing as a whole and offer a comprehensive proposal.

Which to Prioritize? A Guide Based on Your Business Stage

Let's consider your priorities based on your company's situation.

Case 1: For Businesses/Stores That Have Just Launched a Website

  • Priority: SEO / MEO > AIO
  • Reason: The top priority is to get your existence recognized by search engines and have your basic information indexed. Just as no one starts with the interior design (AIO) when building a house, you first need to solidify the foundation and framework (SEO/MEO).

Case 2: For Businesses with Established SEO and Stable Traffic

  • Priority: AIO ≈ SEO / MEO (Concurrent/Additional)
  • Reason: If you already have a wealth of quality content on your website and a stable evaluation from search engines, adding AIO can open up new customer acquisition channels. A strategy of adding semantic meaning to your existing assets (content) with structured data to make it more understandable to AI can be effective in aiming for citations in AI Overviews and other features.

Case 3: For Local Businesses (Restaurants, Salons, Clinics, etc.)

  • Priority: MEO + AIO > SEO
  • Reason: Location-based AI searches like "near me" and "recommended" are the most impactful areas for local businesses. Thoroughly optimizing your Google Business Profile information (MEO) directly contributes to AIO. While website SEO is also important, starting with GBP optimization and linked structured data implementation is often the most cost-effective approach.

The Importance of an Integrated Approach to AIO and SEO

While we have compared AIO and SEO, what we want to emphasize most from an expert's perspective is that they should be considered together, not as an either/or choice.

Web marketing going forward will require a "dual approach" that caters to both users of traditional search engines and users who get information via AI assistants. The common language for both is "structured data," and the foundation of information credibility is "E-E-A-T."

At LillyHoldings, we don't see the AIO in our TrendPackage as some entirely new, special strategy. We believe the essence is to build upon the SEO/MEO knowledge we have cultivated and then optimize for a new information recipient: "AI."

Therefore, our AIO strategy is designed as a comprehensive package that includes a foundational technical SEO audit, local information optimization through MEO, and content credibility enhancement (E-E-A-T). This is because each strategy is not independent; they influence each other to truly enhance a company's or store's online presence. Our fundamental stance is not to focus on a single strategy but to holistically improve a business's entire digital assets.

Conclusion: Prepare Now for the Future of Your Business

In this article, we have explained the differences between AIO and SEO from multiple perspectives, including their purpose, strategies, costs, and how to choose between them.

  • SEO is the "foundation of web marketing" for increasing site traffic from search engines.
  • AIO is the "next-generation acquisition channel" aimed at getting cited and recommended in AI-generated answers.

The key to surviving in the coming digital age is not to choose one over the other, but to work on both with the right balance, tailored to your business stage and characteristics.

When choosing a provider, don't be swayed by buzzwords. Instead, ask fundamental questions like, "Why is this strategy necessary?" "What are the specific tasks involved?" and "How will it integrate with the foundation of SEO/MEO?" The partner who can answer these questions honestly and specifically is the one who will contribute to your business growth.

The shift in the search experience driven by AI has only just begun. Gaining the right knowledge and starting to prepare at this moment will undoubtedly lead to a significant advantage in the years to come.
