Web Data 101

Every team in your business needs fast and accurate insights to make decisions that will help the company succeed. For this reason, companies across industries — from media intelligence to risk management — have turned to web data integration platforms for automated insights. These platforms require a lot of data, especially web data, to perform well. We’ve created this guide to explain what web data is, the use cases for it, and the web data options available today.

What is web data?

Web data is information sourced and structured from various sites across the Internet. Types of web data include:

• Open web data – Publicly accessible data extracted from sources on the open web, such as news sites, blogs, message boards, forums, review sites, and Q&A pages.
• Dark web data – Data obtained from websites within a hidden network, or “Dark Web,” only accessible with a specially designed web browser like TOR. Dark web data includes posts that include leaked or stolen sensitive information, such as credit card numbers, social security numbers, and passwords.
• Deep web data – Data found on sites that traditional search engines do not index and password-protected sources. These sites live on networks such as Telegram and IRC.

We often see confusion around the terms “dark web data” and “deep web data,” so we’ve created an article to explain the differences between these two terms. You can use one or multiple types of web data to gain valuable insights for your business.

Web data use cases

You can use web data for a wide range of use cases, such as:

• Media Intelligence – By monitoring trends across millions of open web data sources, you gain real-time insights into consumer sentiment and industry trends. You can track content performance, brand sentiment, customer experience, and competitor performance.
• Brand Protection – Brands face many online threats today — from inflammatory comments made against them on alternative media sites to malicious insiders selling sensitive company information to third parties. You can uncover these threats by analyzing massive volumes of open, dark, and deep web data.
• Risk Intelligence — Every company today faces a wide range of constantly evolving risks. For example, supply chains can quickly become vulnerable to potential cybersecurity attacks. When corporate executives travel abroad, they face potential safety hazards stemming from crime, terrorism, or natural disasters. Brands face continuous attempts at counterfeiting and unlicensed use of their products. You can use open, deep, and dark data to create more accurate and effective risk assessment solutions.
• Regulatory Compliance — Running a business requires that you manage regulatory compliance well or face potentially huge penalties and fines. Every company faces different regulations depending on the geographic location in which the business operates. Companies also face an increasing number of government regulations. You need access to relevant public government websites to keep up with the latest regulations to ensure your business always remains in compliance.
• Financial Analysis – traditional web data and alternative data across the web contain hidden signals that impact financial markets and investments. You can discover consumer sentiment and economic trends by analyzing critical real-time and historical market information. You can then use that information to create data-driven investment strategies, accurate predictive financial models, and ESG benchmarking solutions.
• Machine Learning — You need high-quality data to build accurate and effective ML models, which typically requires data scientists to spend a lot of time on data cleaning and preparation. Using well-structured and unified web data helps reduce the time data scientists must spend on these tasks. And for certain types of machine learning, like supervised learning, you need quality historical web data to properly train predictive models.

Whatever the use case, you first need to find an efficient and cost-effective way to obtain relevant web data.

Key web data challenges

If you want to leverage web data, the first big challenge is figuring out how to get it. Should you build your own web crawling system, or is it better to buy a ready-made solution? Many companies also struggle with data literacy – having the right skills to make sense of web data. According to Gartner, most chief data officers will fall short in improving data literacy across their teams through 2025, making it even harder to turn web data into actionable insights.  

Start Scaling With Big Web Data

Building an in-house solution

Building your own web crawling solution gives you complete control over how you collect and process data, but it’s a major investment. Developing and maintaining an in-house system takes time, money, and a highly skilled team. Since your data needs to grow, scaling becomes increasingly complex and expensive. Plus, staying compliant with data privacy regulations that are constantly changing means constant updates and monitoring. If you go this route, be prepared for a long-term commitment with ongoing costs and challenges.

Purchasing a third-party solution

Buying a third-party web data solution is the faster, more scalable option. With a ready-made platform, you don’t have to worry about development, maintenance, or infrastructure costs. Leading providers offer tested solutions that can handle massive data volumes while ensuring compliance with industry regulations. The downside? You’ll have less control over how data is collected and may become dependent on vendor-specific technology.

Beyond choosing between building or buying, you’ll also need to address issues like data privacy, security, and integration. With increasing regulations and growing cyber threats, protecting collected data is more critical than ever. You’ll also need to integrate web data with your existing systems while ensuring accuracy and consistency. And, of course, data quality matters – if your data is full of errors or gaps, your insights won’t be reliable.

To make web data work for you, you need a strategy that balances cost, control, and expertise. Whether you build or buy, the key is finding a solution that delivers the insights you need without unnecessary risk or complexity. We cover this topic in more detail in this white paper.

Why structured web data matters in 2025

If you’re using machine learning or large language models (LLMs), structured web data isn’t just helpful – it’s essential. Unlike raw, unstructured data, structured web data is already categorized and formatted, saving you hours of cleaning and prepping before analysis.

For AI-driven applications, structured data eliminates inconsistencies, reduces bias, and improves accuracy. It allows you to extract high-quality insights at scale, making everything from risk assessments to financial forecasting more precise. Plus, structured data is easier to retrieve and index, which means you can integrate real-time information into your models and decision-making processes without delays.

Efficiency is another major advantage. Without structured data, you’ll need to standardize datasets before they’re even usable. By leveraging structured web data, you can train models faster, cut down on operational costs, and generate insights with more confidence.

Looking ahead, companies that prioritize structured web data will gain a clear edge. Whether you’re building AI models, analyzing market trends, or ensuring regulatory compliance, structured data helps you scale, stay accurate, and get results – without unnecessary complexity.

Web data solutions

If you want to buy a web data solution, you have two types to choose from: ad-hoc web scraping or web data feeds via APIs. The solution that will work best for you depends on how much data and scalability you need. For example, a large enterprise would need to leverage massive volumes of web data from different sources. In general, ad-hoc web scraping solutions are designed for small-scale data projects. The ad-hoc solution provides web data based on a list of websites the customer has given the data provider.

On the other hand, a solution that uses high-speed web feeds with flows of different data types would work well for the enterprise. Web data feeds provided through APIs allow businesses to access ongoing scalable flows of web data from numerous websites. They enable companies to generate insights from web data at scale.

The Webz.io platform gathers data from sources across the open, dark, and deep web. We provide this data in the form of feeds which you can integrate into other platforms using our data feed APIs.

The future of web data

Today, web data plays a vital role in decision-making and risk protection for many businesses. But what does the future look like for web data as a whole? In the future, we expect to see the following:

• More annotated web data — More annotated data means that search engines and scraping/crawling solutions will better “understand” the meaning of the data, i.e., its structure for analysis.
• The fusion of web data types — We expect more companies to leverage multiple data types. For example, a company might extract data from news, government, and dark web sites, as one contributes to the other. Analyzing multiple data types adds more dimensions to analysis and brings deeper insights.
• More scraping prevention measures — We predict that more companies will implement measures to protect against illegal scraping. In the future, we expect that fewer reputable sites will be available for scraping, and some web data solutions will resort to evasive scraping techniques, like proxies.

How companies use web data will continue to evolve, and so will solutions for obtaining it.
