Signs of AI Search in GSC: 5 Key Metrics

Introduction: Are You Using Search Console Correctly?

"I've installed Google Search Console (GSC), but I only look at rankings and clicks..."
If this sounds like you, you might be missing out on a huge opportunity. Especially in an era where AI generates search results, GSC has evolved from a simple rank-checking tool into a 'compass' for deciphering AI's thinking and planning future customer acquisition strategies.

As AI search (like Google's AI Overviews) becomes mainstream, the fundamental way users get information will change. In addition to the traditional behavior of "search, click a site, find information," we will see an increase in cases where users simply "read the AI-summarized answer and are done." This means we need to rethink the conventional approaches of SEO (Search Engine Optimization) and MEO (Map Engine Optimization), which have long been based on driving traffic to a website.

This is where the concept of AIO (AI Optimization) becomes crucial. This refers to optimization activities aimed at getting your business's information found, correctly understood, and recommended to users by AI. And the very first step in AIO is to correctly interpret the "signs of AI search" hidden in GSC.

In this article, we will provide a thorough explanation for store owners and small business web managers on the five key metrics to watch in GSC, complete with specific numbers and benchmarks, and the action plans derived from them, so you can start implementing them tomorrow.

Posing the Problem: Why Do We Need to Change How We View GSC Now?

You might be thinking, "Isn't our current SEO approach good enough?" However, the spread of AI search is quietly but surely changing the rules of web-based customer acquisition. There are three main reasons why you should change how you view GSC.

1. The Diversification of Search Results and the Rise of "Zero-Click Searches"

In the past, search results were fundamentally a list of 10 blue links. Now, they are a complex combination of AI-generated summaries, maps, images, videos, shopping ads, and more. AI summaries are particularly powerful and have the potential to accelerate "zero-click searches," where a user's query is answered without them ever needing to visit a website.

This means that only looking at simple "impressions" and "rankings" can lead to a misinterpretation of your business's actual performance. A situation where "our site is showing up, but inquiries aren't increasing" might be caused by these zero-click searches. It's necessary to analyze GSC data more deeply and consider the reasons why your site wasn't clicked.

2. The "Super-Long-Tail" and "Conversational" Nature of Search Queries

Users who are accustomed to interacting with AI will start searching with more specific, longer, and conversational phrases. For example, a search that was once "Nagoya cafe" will transform into a specific question like, "cafes in Naka-ku, Nagoya with power outlets where I can work quietly."

These "super long-tail" queries are difficult to discover with traditional keyword tools. However, GSC's "Search queries" report contains the raw, actual words users have searched for. These represent the hidden needs of users and are a treasure trove of hints for AIO and MEO strategies.

3. The Shift in "Information Quality" as Evaluated by AI

AI places immense importance not just on whether keywords are present, but on the comprehensiveness, expertise, authoritativeness, and trustworthiness (E-E-A-T) of information. It highly values pages that provide the most accurate and reliable "answer" to a user's question.

To be chosen as this "answer," a new SEO perspective is essential. This includes structuring your site's information in a way that AI can easily understand and creating content that proactively answers users' questions. GSC data provides valuable clues about how your site is being evaluated by AI and where you can make improvements to be chosen more often.

Concrete Solutions: The 5 Metrics to Watch in GSC and Signs of AI Search

So, what exactly should you look at in GSC, and how? Here, we'll explain five key metrics for catching the signs of AI search and connecting them to your AIO strategy.

Metric 1: Queries with High Impressions but Low Clicks

• Sign of AI Search This Indicates: Potential "zero-click searches" where the answer is provided completely by an AI summary (AI Overview), resulting in no click to your site.
• Where to Look: GSC Dashboard > Search performance > QUERIES
• Benchmark for Judgment: Question-based queries (e.g., "what is a ~," "how to ~," "~ price") with a CTR (click-through rate) of less than 1%, especially those below 0.5%.

【Specific Action Plan】

1. Assess the Current Situation (Time: 15 min)
   Once you find a query with an extremely low CTR, search for that term yourself in incognito mode. Is there an AI summary at the top of the results? Is your site's information cited within it? Or is a competitor's site being used?
2. Improve Content to Aim for Citation (Time: 1-2 hours/page)
   If a competitor is being cited, write a "concise and easy-to-understand answer" at the beginning of the relevant page on your site that is as good as or better than theirs. AI tends to prefer a conclusion-first structure. Summarizing information in a Q&A format is also effective.
3. Create Incentives to Click (Time: 1 hour)
   It's also important to provide a "reason to read more" rather than letting users be satisfied with the AI summary alone. For a query like "price estimate," for example, instead of just a price list, you can encourage clicks by providing deeper information such as "detailed estimate examples based on customer situations" or "services included/not included in the price."

Metric 2: A Sudden Increase in "New Queries"

• Sign of AI Search This Indicates: As users search conversationally with AI, unique search queries (super long-tail keywords) that no one has used before are being created.
• Where to Look: GSC Dashboard > Search performance > QUERIES > DATE > Compare
• Benchmark for Judgment: When comparing time periods (e.g., last 28 days vs. previous 28 days), look for long queries of 5 or more words that previously had 0 impressions but have suddenly appeared with a few to several dozen impressions.

【Specific Action Plan】

1. Discover Treasure Queries (Time: 30 min/month)
   Once a month, use the date comparison feature to list newly emerged queries. For example, you might find a query like "private party rental with projector in Chikusa-ku, Nagoya." This represents a very specific need that your existing pages may not fully satisfy.
2. Create Content to Serve as a Landing Page (Time: 2-3 hours/article)
   The queries you discover are the best inspiration for new content. For the example above, you could create a blog post or a dedicated page titled "5 Benefits of Hosting a Private Party with a Projector at Our Venue." By including specific details about your facility's equipment and past event examples, you can perfectly answer the user's question. This not only serves as high-quality SEO content but also becomes a powerful MEO measure.

Metric 3: Performance in the "Search Appearance" Report

• Sign of AI Search This Indicates: AI prefers structured data. How your reviews, FAQs, event information, and other elements are displayed in search results (as rich results) is a key barometer of whether you are communicating information correctly to AI.
• Where to Look: GSC Dashboard > Search performance > SEARCH APPEARANCE
• Benchmark for Judgment: Check if impressions or clicks are being recorded for items like "FAQ rich results," "Review snippets," or "Product rich results." If they are, is their CTR higher than your site's overall average CTR?

【Specific Action Plan】

1. Check Implementation Status (Time: 15 min)
   If the "Search Appearance" report doesn't show items corresponding to the information you offer on your site (like FAQs, products, reviews), it's possible that structured data is either not implemented or not being recognized by Google.
2. Implement Structured Data (Time: 1-2 hours/page type)
   To accurately convey your store or service information to AI, implement structured data. If you're using WordPress, you can set this up relatively easily with a dedicated plugin. For example, for store information, you would embed code like the following into your page. This allows AI to accurately understand the address, phone number, business hours, and more.
   

   <script type="application/ld+json">
   {
     "@context": "https://schema.org",
     "@type": "LocalBusiness",
     "name": "あなたの店舗名",
     "address": {
       "@type": "PostalAddress",
       "streetAddress": "中区三の丸３丁目１−１",
       "addressLocality": "名古屋市",
       "addressRegion": "愛知県",
       "postalCode": "460-8501",
       "addressCountry": "JP"
     },
     "telephone": "052-123-4567"
   }
   </script>

Metric 4: "By Device" Performance, Especially Deterioration on Mobile

• Sign of AI Search This Indicates: The primary use case for AI search is on mobile, including voice searches and on-the-go searches like "__ near me." Mobile usability directly impacts AI evaluation.
• Where to Look: GSC Dashboard > Search performance > DEVICES
• Benchmark for Judgment: When mobile accounts for the majority of impressions (e.g., over 70%), but the mobile CTR or average position is significantly lower than on PC (e.g., CTR is less than half of PC's, position is 5 or more ranks lower).

【Specific Action Plan】

1. Check for Technical Issues (Time: 20 min)
   Go to GSC's "Page Experience" > "Mobile Usability" report and check for errors like "Text too small to read" or "Clickable elements too close together." If there are errors, ask your website developer to fix them.
2. Check the Actual User Experience (Time: 15 min)
   Try using your own website on your smartphone. Do images load slowly? Can you tap the phone number to call immediately? Is the contact form tedious to fill out? Beyond technical errors, this kind of perceived difficulty in use can also cause users to leave.

Metric 5: "Indexed, not submitted in sitemap" in the Pages Report

• Sign of AI Search This Indicates: AI tries to understand the overall context and structure of a site. Important pages not listed in your sitemap, or low-quality pages indexed unintentionally, can lower your site's overall evaluation and create noise that prevents AI from correctly interpreting your information.
• Where to Look: GSC Dashboard > Indexing > Pages
• Benchmark for Judgment: The URL list for this status contains important service pages or blog posts that should be communicated to Google. Alternatively, it contains test pages or thin-content tag pages that don't need to appear in search results.

【Specific Action Plan】

1. Check and Correct Your Sitemap (Time: 30 min)
   If important pages are on this list, your sitemap (sitemap.xml) may not be generating or submitting correctly. Review your WordPress plugin settings and ensure your sitemap is set to update automatically when a new page is added.
2. Clean Up Unnecessary Pages (noindex setting) (Time: 1 hour)
   Conversely, if low-quality pages that don't deserve to be in search results (e.g., empty category pages, internal search result pages) are being indexed, set a <meta name="robots" content="noindex"> tag in the page's HTML to request their removal from the index. This helps maintain a high overall site quality and improves your evaluation from AI.

Practical Steps: A GSC Monitoring Checklist to Start Tomorrow

Understanding the theory is not enough. Here are practical steps to make analysis a habit and turn it into concrete action.

Step 1: Detect Anomalies with a Weekly Check (Time: 30 min/week)

Make it a habit to check GSC at a set time, such as every Monday morning. The goal is to spot major changes or problems early.

【Weekly Checklist】

• [ ] Search Performance > Queries: Has the CTR for queries containing your main service or product names dropped suddenly? (Benchmark: a drop of 30% or more from the previous week)
• [ ] Search Performance > Queries: Are there any question-based queries with a CTR below 1% that you should address?
• [ ] Page Experience: Have any new errors appeared in Mobile Usability or Core Web Vitals?
• [ ] Indexing > Pages: Has the number of "Errors" increased sharply?

Step 2: Formulate Strategy with a Monthly Review (Time: 1.5 hours/month)

At the beginning of each month, review the entire previous month's data for deeper analysis and to create an action plan for the next month.

【Monthly Checklist】

• [ ] Period Comparison Analysis: Identify queries and pages with significant changes in impressions/clicks month-over-month or year-over-year, and hypothesize the cause (seasonal factors, content updates, algorithm changes, etc.).
• [ ] Deep Dive into the 5 Metrics: Conduct a detailed check of each of the five metrics discussed in this article (signs of zero-click search, new queries, rich results, mobile performance, index status).
• [ ] Content Planning: Based on the newly discovered "treasure queries," decide on one or two topics for blog posts or FAQs to create next month.
• [ ] List Improvement Tasks: Create a list of concrete improvement tasks, such as implementing structured data, setting noindex on low-quality pages, or requesting mobile usability fixes.

Step 3: Execute, Record, and Iterate

Put the plan from Step 2 into action. And most importantly, 'record' your actions. Keep a simple log in a spreadsheet of "what changes were made to which page on what date." This record will allow you to accurately review the effectiveness of your measures months later, dramatically improving the precision of your next improvement cycle.

Summary

In the age of AI search, Google Search Console is more than just a rank-tracking tool. It is a "treasure trove of needs" filled with the raw voice of the user, and a "mirror" reflecting how AI evaluates your site.

The five metrics we introduced are specific perspectives for looking into that mirror to find hints for future customer acquisition.

1. Low CTR Queries: Signs of zero-click searches
2. New Queries: Hidden user needs
3. Search Appearance: A report card on your information transfer to AI
4. Mobile Performance: A basic requirement in the AI search era
5. Index Status: Overall site quality control

Regularly monitoring these metrics and channeling the insights into steady site improvements (AIO) is the key to success in future SEO and MEO strategies.

Start with a 30-minute weekly check. The time you spend engaging with your GSC data will become a powerful support for your store's future customer acquisition.
