Compared to traditional interview-based research, online research offers significant advantages: it can be conducted at lower cost, in less time, and allows you to gather a wide variety of information.

That said, online research is not a silver bullet. If the research design is flawed, you may end up simply “collecting the answers you wanted to hear,” “mistaking a subset of opinions for the entire market’s needs,” or “concluding that a product will sell when it actually won’t.”
In this article, we introduce the latest online research methods and key tools you can actually use, while walking you through an approach to research that genuinely supports business decision-making.

1. Online Research Is a Tool for Testing Hypotheses, Not Just a Cheap and Fast Way to Ask Questions

When people hear “online research,” they often think of surveys. But today’s online research goes far beyond simply conducting questionnaires on the internet. In practice, online research methods broadly fall into the following categories:

Search Data Analysis
Website Access Analysis
Competitor Site Analysis
Social Media & Review Analysis
Online Survey Research
Web Behavioral Log Analysis
E-commerce & Review Analysis
AI-Assisted Information Gathering, Summarization & Hypothesis Structuring

What matters is not rushing straight to the tools. The first question to answer is: “What decision is this research meant to support?”

For example, consider a metal fabrication subcontractor that wants to leverage its long-cultivated machining expertise to develop consumer-facing (B2C) products. Before launching any research, it would need to frame questions such as:

  • ►Which consumer product categories can leverage our fabrication capabilities?
  • ►Which market holds the most potential—interior goods, outdoor gear, kitchen items, stationery, pet products?
  • ►What value do consumers see in metal products?
  • ►Do attributes like “high precision,” “durable,” “long-lasting,” and “premium feel” actually drive purchase decisions?
  • ►What price range would consumers accept?
  • ►Compared to competing products, on what basis should our product win?

If research begins without these questions clearly defined, you may gather plenty of data — but it will fail to lead to any meaningful decisions.

2. Reading “Explicit Needs” and “Market Temperature” from Search Data

Analyzing search data is one of the most effective first steps in online research. People turn to search engines when they have a problem to solve, something they want, or a challenge they need to address. By examining search data, you can understand what language consumers and business buyers use to articulate their challenges, and which topics are attracting growing interest.

Here are the key tools available:

Google Trends lets you see how often a particular keyword is searched, across different time periods and regions. For example, a metal fabricator developing B2C products could compare search trends for terms like “metal interior,” “iron furniture,” “stainless kitchen goods,” “brass accessories,” “titanium outdoor gear,” or “aluminum stationery” — helping identify whether a topic represents a short-lived trend or sustained consumer interest.

It’s also important to search using terms that describe use cases and everyday situations rather than material names — for instance, “garage storage,” “camp gear,” “desk organization,” “stylish pet supplies,” or “entryway interior.”

Metal fabricators tend to think in terms of their processes — cutting, sheet metal work, welding, anodizing — but consumers rarely search using these technical terms. A consumer’s search is more likely to be something like “I want durable camping gear.” Google Trends helps you form an initial hypothesis about which markets and everyday scenarios your technical capabilities can best serve.

Note: Google Trends shows relative interest, not absolute search volume. Do not use it alone to judge market size — always combine it with other data sources.

Part of Google Ads, this tool lets you check search volume by keyword and gauge competition in the advertising space. For a metal fabricator exploring B2C products, you could research terms such as:

  • ►Iron shelf
  • ►Stainless steel storage
  • ►Brass accessories
  • ►Aluminum business card holder
  • ►Titanium camping gear
  • ►Metal pet products
  • ►Stylish entryway umbrella stand

This tool can reveal a gap between the language your company uses to describe its products and the language consumers actually use when searching. For instance, your company might describe itself as offering “products made with precision sheet metal technology,” while consumers are searching for “stylish metal storage” or “space-saving umbrella stand.”

In search data research, the key is finding the everyday-problem language that customers are actually using — not the technical language your company wants to promote.

Note: As of the time of writing (June 2026), Google Keyword Planner’s full functionality — including specific search volume data — is only available to active Google Ads accounts. Please be aware of this limitation.

3. Understanding Real Interest from Your Own Website’s Access Data

Online research should not only look outward at the broader market — analyzing the behavior of users already visiting your own website is equally important. Key tools include the following:

Google Analytics 4 is an access analysis tool that lets you see how users arrived at your site, which pages they viewed, how long they stayed, and whether they converted. It can answer questions such as:

  • ►Which pages are being viewed most frequently?
  • ►Which traffic sources are generating inquiries?
  • ►On which pages are users dropping off?
  • ►Is there a behavioral difference between smartphone and desktop users?
  • ►Which channel — paid ads, organic search, social media, or referrals — is driving the most results?

Even for a metal fabricator exploring B2C products, the access data from an existing B2B website can be revealing. For example, if pages covering topics such as “stainless steel processing,” “aluminum machining,” “exterior parts,” “bending fabrication,” “surface treatment,” or “small-lot production” are receiving significant traffic, this indicates which technologies and materials are attracting external interest.

Additionally, by creating test pages or landing pages aimed at B2C audiences and monitoring their traffic, you can gauge which product concepts are generating actual response.

Google Search Console tells you how your website is appearing in Google search results and which keywords are generating clicks. If Google Analytics shows you “what users do after arriving at your site,” Search Console shows you “what users were searching for before they arrived.” The most valuable data includes:

  • ►Search keywords generating a high number of impressions
  • ►Keywords that are actually being clicked
  • ►Keywords where your ranking is rising or falling
  • ►Pages that appear in search results but are not being clicked
  • ►Topics with clear search demand that your site is not yet addressing

For example, if your site is being displayed and clicked for searches like “stylish metal products,” “long-lasting storage,” or “durable camping gear” rather than “metal fabrication technology,” that is a strong signal that you are already reaching general consumers.

4. Comparing “Reasons for Being Chosen” Through Competitor and Industry Site Analysis

Market research that only looks at your own company is never sufficient. Customers are always comparing you to alternatives. Today, with search engines and generative AI making it easy to compare multiple companies in a matter of seconds, businesses need to think not only about “being found,” but about “remaining in the running once the comparison starts.”

Key tools include the following:

Similarweb is a competitive analysis tool that provides estimated traffic figures, traffic channels, referral sources, search keywords, and visitor interest areas for competitor websites. It helps you understand how your competitors are driving web traffic — information that is invisible from your own site alone.

For a metal fabricator developing B2C products, your direct competitors are not limited to other metal fabrication companies. You also need to examine players such as:

Metal interior goods brands
Storage product manufacturers
Camping & outdoor gear brands
Pet product brands
Stationery & desk accessory brands
Companies selling metal products via crowdfunding
Top-ranking similar products on e-commerce platforms

Using Similarweb, you can understand which channels each of these competitors relies on for traffic — whether they are strong in organic search, social media, advertising, or third-party media referrals.

Note: Similarweb figures are estimates, and accuracy can be limited for smaller websites with lower traffic. Rather than treating the numbers as absolute truth, use the tool to compare trends across competitors and identify differences in traffic channel mix.

Other Competitor Analysis Tools

There are many other competitor site analysis tools available. Many carry a high price tag (annual fees reaching tens of thousands of dollars), so it is worth choosing based on your budget and specific needs.

Semrush

A global competitive analysis and SEO tool. Annual subscription costs are high.

Dockpit

A web analytics tool focused on the Japanese domestic market. Annual fees are high.

Rakko Keyword

Starting from a few thousand yen per month. Provides a solid overview of competitor site traffic and inflow keywords at a cost-effective price point.

5. Validating Price, Comparisons, and Use Cases with Online Surveys

Online surveys are one of the most representative methods of internet research. Today, you no longer need to commission an expensive specialist firm — self-service survey tools allow you to run research quickly and independently.

Key tools include the following:

A globally recognized survey platform with robust question branching, tabulation, and analysis features. Particularly well-suited for international surveys and English-language questionnaires.

Example: A 10-question survey targeting 200 women aged 30–60 in the United States costs approximately $300–$600 USD.

A self-service survey tool provided by Macromill. Its intuitive interface makes it accessible even to users unfamiliar with research methodology.

Also supports panel surveys using Macromill’s registered respondent base. Primarily focused on the Japanese domestic market.

A low-cost, fast self-service online research tool. Well-suited for lightweight market validation and hypothesis testing.

Example: A 10-question survey targeting 200 Japanese women aged 30–60 costs 22,200 yen (tax included). Pricing is straightforward: questions × respondents × 10 yen (excl. tax). Available for domestic Japan surveys only.

Whether you are surveying internationally or domestically will determine which tool is most appropriate. Always compare features and pricing estimates before committing to a platform.

One critical point: simply asking “Would you buy this product?” in an online survey is dangerous. Respondents often say they would buy something even when they never actually would. Questions must be made more concrete and conditional, such as the example below.

Good question example

“If this metal desk organizer were listed on an e-commerce site at a price of $65 USD (tax included), would you switch from your current storage solution and purchase it?”

Beyond that core question, you should also gather the following information:

  • ►What products do they currently use?
  • ►How much do they pay for similar products?
  • ►Where do they expect to buy it — which retailer or e-commerce site?
  • ►In what situations or contexts would they use it?
  • ►What appeals to them compared to competing products?
  • ►Do they see value in the fact that it is made of metal?
  • ►Do they have concerns about weight, price, maintenance, scratches, or rust?
  • ►What are the reasons they would not buy it?

Survey results can vary enormously depending on how questions are framed. Rather than steering respondents toward the answers you hope for, designing the survey to surface reasons for not buying and reasons for not being chosen is what leads to genuinely useful insight.

6. Uncovering the Real Voices of Consumers Through Social Media and Reviews

Surveys only capture what respondents consciously choose to say. Social media posts and online reviews, by contrast, contain the unfiltered frustrations, surprises, comparisons, and real-world experiences that consumers share naturally in their daily lives. For this reason, social media and review analysis is a valuable source of inspiration for product development and advertising messaging.

Key tools include the following:

Brandwatch is a social listening and consumer insight analysis tool that collects and analyzes online conversations about brands, products, competitors, and industry themes — covering volume, sentiment, trends, and related keywords. For a metal fabricator considering B2C products, it is well-suited for research such as:

  • ►Extracting frustrations related to metal interior goods
  • ►Analyzing user experience with camping and outdoor gear
  • ►Understanding pain points with storage products
  • ►Capturing consumer opinions on pet product safety and design
  • ►Reputation analysis of competing brands
  • ►Understanding the language used by younger and design-conscious consumer segments

As a global social listening tool, Brandwatch is especially effective when cross-border comparisons are part of your research goals.

Provided by Plus Alpha Consulting Co., Ltd., Mieruka Engine is an analysis platform with particular strengths in review analysis, social media monitoring, and text mining. It processes diverse text data — including social media posts, review sites, open-ended survey responses, and inquiry records — to visualize consumer dissatisfaction, evaluation patterns, emotional tone, trending topics, and related keywords.

While global tools like Brandwatch are powerful for international market research, for domestic product development and marketing planning in Japan, Mieruka Engine’s ability to handle Japanese-language reviews, SNS posts, and survey free-text responses makes it a highly practical choice in real-world projects.

7. Using Generative AI to Speed Up Research Preprocessing and Hypothesis Structuring

Generative AI is increasingly being applied within online research workflows. Tools like ChatGPT, Gemini, and Claude can streamline research design, competitive comparison, organization of public information, survey question drafting, review analysis, and hypothesis generation.

Key tools include the following:

Generative AI is effective for tasks such as:

Clarifying research objectives
Generating a list of hypotheses
Creating frameworks for competitor comparison
Drafting survey question sets
Preparing interview question guides
Categorizing customer reviews
Summarizing social media posts and reviews
Creating first drafts of research reports

However, generative AI is not a substitute for actual research findings. AI outputs can contain errors and speculation. While AI excels at producing plausible-sounding general conclusions, it has no knowledge of your company’s specific machining precision, equipment, cost structure, production capacity, quality control standards, inventory risk, or existing customer relationships. Generative AI should be treated as an assistant that accelerates the groundwork for research — not as a decision-maker.

8. Summary: Online Research Is a Means of Gathering Decision-Making Material, Not Answers

Online research is a powerful approach that allows you to gather a wide range of information at relatively low cost and in a short time. By combining Google tools, competitor analysis platforms, survey tools, social listening tools, and generative AI, you can gain a far more efficient understanding of market shifts and customer needs than was possible with traditional methods.

That said, online research is not omnipotent — and it is certainly not a means of reinforcing a convenient story you have already decided to tell. By thoughtfully combining search data, web behavioral data, surveys, social media, competitive analysis, and AI, you can more objectively assess which everyday scenarios have unmet needs, at what price points purchases actually occur, and how your product’s strengths translate into value for customers. From there, the path forward is through test marketing — moving from “this looks like it will sell” toward building a business that actually sells.
