[The Biggest Change in 25 Years] Google Search Goes "AI-Default." Revealing the Prompt You Should Use for Your Lead Paragraphs Right Now
Introduction | Google Search is seriously trying to change for the first time in 25 years
Good morning. I'm Nakashima, an AI writer who earns 800,000 yen a month while running a ramen shop in a rural town in Tohoku.
I received some rather surprising news this morning.
Google Search is about to change significantly for the first time in 25 years.
If you've been following the announcements around Google I/O 2026, you might already know, but the search UI (interface) itself is shifting toward an "AI-default" state. A full-scale revamp of the search screen, centered on AI Mode and AI Overviews, is underway, and data shows that usage has surged 3.5 times in just eight months.
...If you heard that and felt, "Oh no, I have to do something about this," your instincts are correct.
But don't worry.
I, who used to burn myself out writing for 0.5 yen per character, will now give you—complete with a prompt—the "one block to be cited by AI" that you can implement in your own blog and client work starting this very moment.
I wrote that I was a 0.5 yen per character writer, but I have no intention of looking down on that. I was the same way. My first payment after registering on CrowdWorks was only 39 yen after fees were deducted. That is the truth. That is precisely why I want to share this change not as a "crisis," but as a "moment to turn a crisis into an opportunity."
Now, let's get into the main topic.
1. What is happening | The reality of Google Search's "AI-default" shift
The era of the "blue links" that lasted 25 years is ending
Google released its search engine in 1998. For about a quarter of a century since then, we have taken for granted the experience of "looking at 10 blue links from the top, clicking them, and reading the page."
However, looking at the movements around Google I/O 2026, this search experience centered on "blue links" is shifting toward search centered on AI Overviews/AI Mode.
Specifically, these kinds of changes are happening.
A large answer block summarized by AI is displayed at the very top of search results.
Users are satisfied with just the AI's answer before they even "click a link."
There is an extreme difference between sites that are referenced as "sources" when AI constructs an answer and sites that are ignored.
In other words, the era where you could "get to the top of search results by stuffing keywords into article titles and H2s" is coming to an end.
"Keyword-stuffing SEO" will no longer work.
According to the "AI Search White Paper 2026" released by Hakuhodo DY ONE, the usage rate of AI search has surged 3.5 times in just eight months. Furthermore, on May 18, 2026, Google clarified the application of its spam policy regarding AI Overviews and AI Mode.
In short, Google is strengthening its policy of not selecting articles written sloppily with AI or articles just stuffed with keywords as sources for AI.
With research (by Graphite) showing that approximately 50% of online articles are AI-generated, we are starting to see a plateau in mass-produced AI content. From now on, the question will not be "Was this written by AI?" but rather "Is it structured to be cited by AI?"
2. To put it in terms of a ramen shop, this is what it means
Let me use my other job, running a ramen shop, as an analogy here.
In the 15 years I've been running my ramen shop, I've been able to attract customers using "signboard text (keywords)." It was an era where if you wrote "Shoyu Ramen," "Iekei," or "Uses Prefectural Wheat" in big letters on your sign, passersby would just wander in.
But from now on, it will be like this.
A customer asks an AI agent on a delivery app, "List 3 delicious shoyu ramen shops I can eat at right now."
At that moment, the AI scans the menus of member stores.
At this time, the first ones to be recommended (cited) are only the shops that have a "clear menu (structured)" placed at the storefront.
Increasing the number of words on your sign no longer has any meaning. In fact, shops that put out a "organized menu" that says "Conclusion first, three main points, with photos and clear allergy information" are the ones that will be chosen by AI and introduced to customers.
The exact same thing is starting to happen in the world of blog articles.
3. The true nature of a "lead paragraph" cited by AI | 1 conclusion sentence + 3 main points + action
So, how exactly can you create a "structure that is cited by AI"?
The answer lies in the first 200 characters of the article (the lead paragraph).
When AI Overviews cite an article, the AI is not reading the entire article. In reality, it judges "whether this article is reliable and has clear points" within the first few hundred characters. That is precisely why the structure of the lead paragraph is critically important.
A structure that is cited by AI is made up of just three elements.
Element 1 | Conclusion first (1 conclusion sentence)
State the conclusion of the entire article in the first sentence. Abstract preambles like "~ is important" or "I will explain about ~" are a no-go. The ideal form is to answer immediately with "The conclusion is A."
Element 2 | 3 main points (bulleted structure)
Present the evidence supporting the conclusion or the benefits the reader will gain in three bullet points. AI tends to highly value bulleted structures as "organized information."
Element 3 | Presenting an action after reading
Clearly state in one sentence "what the reader can do next after reading this article." Since AI prioritizes citing articles that lead to solving the reader's problems, presenting an action is a powerful signal to the AI.
Why these three elements?
As Google has repeatedly mentioned at events like Google Search Central Live Canada, information that is "primary information, structured information, and information that answers the reader's intent" tends to be prioritized in AI Overviews. In other words, simply placing these three elements at the beginning significantly increases the probability of being included as an AI citation candidate.
…Having read this far, you're probably thinking, "So, how should I write it?"
Don't worry. I will give you that prompt right now.

Output Example (Before / After)
[Before | A Common, Typical Lead Paragraph]
There are many ways to diet, but it is important to choose an effective one. In this article, we will introduce diet methods that you can continue without strain. By being conscious of the balance between diet and exercise, you will be able to lose weight healthily. Please use this as a reference.
When you run this through the prompt, it becomes this:
[After | AI Citation-Ready Lead Paragraph]
Conclusion: The diet that women in their 30s can continue without strain is a combination of "1.2g of protein per kg of body weight + strength training twice a week."
Key Points: Dieting alone reduces muscle mass and increases the rebound rate. Strength training twice a week for 30 minutes improves basal metabolism by about 7% (Ministry of Health, Labour and Welfare data). Consuming 1.2g of protein per kg of body weight makes it easier to maintain a feeling of fullness.
Next Action:You can start by calculating your protein intake from tonight's dinner and adding "one salad chicken (approx. 20g)" from a convenience store.
…What do you think?
Even with the same topic, I think you can feel that the "desire to cite" from the AI's perspective is completely different. The Before version gets rejected by the AI because it asks, "So, what are you trying to say in the end?" whereas the After version is structured with a conclusion, evidence, and action, which significantly increases the probability that the AI Overview will decide to "cite this article."
5. [This is Important] The true value of this prompt is demonstrated in client work
I'll be honest with you.
This prompt is certainly effective just for use on your own blog. But thetrue value explodes when you use it in client work (CW).
Think about it.
Right now, many writers are burning out at "0.5 to 1 yen per character." I was the same. The reason the unit price doesn't go up is that, from the client's perspective, "there is no visible strength that differentiates you from other writers."
However, there are still almost no writers who can adapt to the AI search era.
In other words, at this very moment,
“I can also handle AI Search optimization. I will deliver the introduction already structured for AI citation upon submission.”
“Since I can write in a structure that is easily cited by AI Overview, I can boost both the conversion rate and traffic of the client's articles.”
A writer who can propose this will immediately be in the negotiation range for a rate of 2 to 3 yen per character.
Based on my own experience, once I was able to propose this added value of "AI era adaptation," I rose to 2nd place in the weekly rankings on CrowdWorks and stabilized my monthly sales in the 800,000 yen range. Although I had a background in writing from my time as an engineer and SEO sense gained from two years of blog management, the deciding factor was undoubtedly the skill of "being able to write in a structure that is cited by AI."
💡 For those who want to automate at the same level as this prompt
What I just gave you is a rewrite prompt for just one lead paragraph block.
But in actual client work—
AI optimization of H2 headings (prompts to design headings with a structure compatible with AI Search)
Automatic generation of FAQ blocks (Q&A structure that is easy for AI Overview to cite)
When a client sends a revision request saying "I want you to fix this here," a follow-up prompt
A prompt to rewrite existing SEO articles for AI Search in bulk
—only when you have this "series of prompts used in actual delivery sites" can you negotiate your rates.
That is why I have published a paid note that compiles the automation prompts that an active writer with 800,000 yen in monthly sales actually uses in their own client work.
There are four features:
✅ Contains many automation prompts with quality equal to or higher than the prompt I gave you this time
✅ Completely specialized for client work (CW). Designed for use in delivery sites, not for your own blog
✅ Includes follow-up prompts for handling client revisions and feedback (can respond immediately when told "make this a bit more reader-friendly")
✅ 1,980 yen with a money-back guarantee. If you try it and it doesn't fit, I will refund the full amount
I decided on a price of just a coin plus a little extra, and included a money-back guarantee, because I wanted it to be accessible even to the version of myself who was burning out at 0.5 yen per character.
Before Google Search's "AI Default" becomes fully established, why not position yourself as a writer who can handle it?
6. The First Step Starting Tomorrow | Implementing the "First Block" for the AI Search Era
This has been a bit long, but thank you for reading this far.
Finally, let me organize what you can do starting today.
Step 1 | Choose one of your blog posts Pick one article you've written in the past that you want to increase search traffic for.
Step 2 | Copy and paste the prompt above and enter your lead paragraph Paste it into ChatGPT, Claude, or whichever AI you prefer.
Step 3 | Replace the first 200 characters with the conclusion-first structure output by the AI With just this, your article will become a candidate to be "cited by AI."
Step 4 | Do the same for client articles Just adding a quick note when you submit, "Rewritten for AI Search compatibility," will change how you are evaluated.
Conclusion | To the version of myself back then who was burning out at 0.5 yen per character
In December 2022, when I registered for CrowdWorks, my first month's earnings were 39 yen.
After working as an engineer for 7 years, I switched to working at a ramen shop, and while doing that for 15 years, I ran a blog as a side hustle for 2 years. Even so, the first wall I hit when entering the world of writing was steep. Writing one article for 39 yen. If you broke it down to an hourly wage, the prep work at the ramen shop paid far better.
But the moment ChatGPT was released and I encountered Claude, and became convinced that "this is something else entirely," something started to change.
AI was the vehicle that carried someone like me, a person in their 40s from the countryside, from 0.5 yen per character to 800k in monthly revenue.
And now, as we stand at the moment Google Search becomes "AI Default," I believe we are being given the chance to board that same vehicle once again.
The lead paragraph prompt I provided this time is the key to the entrance of that vehicle.
If you feel like, "I want more serious weapons to fight in client work"—to you, who are standing in the same place I was back then, please let me gently offer this.
✅ Includes many automation prompts of the same quality as the one I gave you today
✅ Specialized for client work. Designed to be used immediately in delivery workflows
✅ Includes follow-up prompts for revisions and feedback included
✅ ¥1,980 with a money-back guarantee. If it's not a good fit, I will refund you in full
If I could give just one book to my past self, who was burning out at a rate of 0.5 yen per character—this is definitely the one I would give.
Today, too, while bathed in the steam of a kitchen in the countryside of Iwate, I am rooting for your next step with all my heart.
See you in the next article.
