Key Takeaways
Many businesses face a practical challenge after adopting AI systems: they have internal data such as orders, customer records, product information, and sales data, but external information such as market trends, competitor information, product prices, and industry news does not automatically enter their AI systems.
If businesses want AI to support market research, competitor analysis, price analysis, or content analysis, they first need to obtain enough external data.
The internet contains a large amount of publicly available information, but this data is scattered across different websites and often presented in different formats. Small amounts of information can be collected and organized manually. Standardized data can be obtained through public datasets or APIs. When information needs to be collected from a large number of webpages on an ongoing basis, web scraping provides a more flexible approach.
AI data collection is not a single technical process. The appropriate approach depends on the data source, data volume, update frequency, and intended use.
Many AI applications rely heavily on internal business data, such as orders, customer information, products, and sales. However, internal data alone is often not enough to understand broader market changes.
The internet contains a wide range of publicly available information outside a company’s own data, including product information, prices, market trends, industry news, public resources, and competitor product information. This information is distributed across different websites and can change quickly, making it useful for supplementing internal business data.
For example, businesses can use public information to understand product and price changes across different markets, monitor new products and pages from competitors, or collect industry articles and public resources for content analysis. Internet data can also support AI applications such as information retrieval and knowledge bases.
However, this information does not automatically enter an AI system. Businesses first need to determine where the data comes from, how to collect it, and how to organize it.
Depending on data volume, structure, update frequency, and source, AI projects can use different methods to obtain internet data.
Manual collection is the simplest way to gather data.
If you only need a small amount of product information, a few industry resources, or data for a one-time market research project, searching webpages and organizing the information manually may be sufficient. This approach does not require a complex data processing system and can also be useful when validating data requirements during the early stages of a project.
However, manual collection becomes less efficient as the amount of data increases. Repeated copying and organizing take time and can lead to missing information, duplicates, or inconsistent formats.
In practice, manual collection is more suitable for small, temporary, or one-time tasks. Projects that require large amounts of data on an ongoing basis may need a more automated approach.
Public datasets are another common data source.
Some research organizations and data platforms provide datasets that have already been collected and organized. Using an existing dataset can reduce the work involved in gathering and initially processing the information.
This approach works well when data requirements are clear and real-time updates are not essential. For example, an existing dataset may be sufficient for historical market research or data analysis.
However, the fields, coverage, and update schedule of a public dataset are generally determined by its provider. If you need very specific information or frequently updated data, an existing dataset may not fully meet your requirements.
An API can be understood as a structured interface provided by a data service.
When using an API, users send requests according to the specified format and receive the corresponding data. Because the returned information is usually organized in a consistent structure, it can be easier to process.
APIs are suitable for scenarios where the data source is stable, the structure is clear, and information needs to be obtained regularly. If a reliable API is already available for the required data, using it can often be more efficient than processing webpages directly.
However, APIs also have limitations. The information available depends on the service provider, and not every website offers an API. Even when an API is available, there may be restrictions related to access permissions, request limits, data coverage, or other conditions.
When the required information is mainly available on webpages but there is no suitable dataset or API, web scraping can provide a flexible option.
The basic process is to access a target webpage, retrieve its content, extract the required information, and then clean and organize the collected data before storing it.
For example, a business may collect public product information to monitor prices in a specific market, gather product names, prices, and descriptions for competitor research, or collect industry articles to analyze changes in a particular field.
Compared with manual collection, web scraping is more suitable for larger amounts of data and can reduce repetitive work. However, practical implementation also requires consideration of website structure, dynamic content, access frequency, and other factors.
Once you decide to obtain data from webpages, the process involves more than simply collecting page content. A typical workflow includes several stages.
Define the data requirements. Before collecting anything, determine exactly what information is needed, which fields should be included, how much data is required, how often it needs to be updated, and what the AI system will ultimately do with it.
For example, if you are researching a product market and only need to monitor price changes, product names and prices may be enough. For competitor analysis, you may also need product descriptions, ratings, and other information. Clear requirements make the later collection and processing stages easier to plan.
Identify the data sources. Once the requirements are clear, find the relevant websites or webpages and determine whether their information meets your needs.
In addition to checking whether the required information is available, consider whether the data is complete, how frequently it is updated, and whether the website structure and data organization are suitable for further processing.
Retrieve webpage content. After identifying the sources, a collection process needs to access the target webpages and retrieve their content.
A webpage usually contains much more than its main text, including navigation, images, recommendations, reviews, and other elements. Retrieving the page is therefore only the beginning and does not mean that the required data is ready to use.
On simpler webpages, the required information may be available directly in the page content. On dynamic webpages, some information may only appear after additional browser-based loading, requiring an approach that can process dynamic content.
Extract the required information. After retrieving the webpage, the next step is to identify the information that actually matters.
For example, a product page may contain product names, prices, images, reviews, and recommended products, while an AI market analysis project may only need the product name, price, rating, and description.
The required data fields should be defined according to the project’s purpose, and information should be extracted into a consistent structure. If the same type of information is presented differently across webpages, additional processing may be needed.
Clean and organize the data. Raw collected data is usually not ready to be used by an AI system. It may contain duplicate information, empty fields, irrelevant text, or inconsistent formats.
Before the data enters the AI system, it may need to be cleaned by removing duplicates, standardizing fields, handling missing information, and filtering out irrelevant content.
Store the data for AI use. Once the data has been organized, it can be stored in a suitable format, such as a spreadsheet, database, or other structured data format.
The processed data can then be used by AI applications for information retrieval, content analysis, market research, knowledge bases, and other tasks.
Overall, web scraping is mainly about turning information scattered across webpages into structured data that AI can process and use. Data cleaning and organization are essential for ensuring that the collected information can be effectively applied.
Different websites use different page structures, and even pages within the same website may not always be identical.
On some webpages, the main information is directly available in the page content. On others, the complete information may only appear after the browser loads additional content. The collection method should therefore be selected according to the characteristics of each webpage.
Website redesigns, layout changes, field updates, and content changes can all affect an existing data collection process.
If data needs to be collected over a long period, it is important to monitor whether the website structure remains stable and leave room for future adjustments.
News and real-time market information may need frequent updates, while industry reports and product resources may only need to be updated every few days or weeks.
The appropriate collection frequency should be determined by how quickly the underlying data changes.
Sending a large number of requests within a short period may result in failed requests or missing data.
When collecting data, access frequency should be planned according to the data volume and update requirements. Failed requests and abnormal results should also be monitored to maintain data quality.
When researching multiple countries or markets, regional differences should also be considered.
The same website may display different languages, currencies, products, prices, or search results depending on the user’s location.
For projects that require data from specific markets, the collection setup may need to account for the target region. In some cases, residential IPs associated with the target market can be used to obtain data that more closely reflects that market.
For example, 1024Proxy provides residential IP resources across multiple countries and regions for use cases involving multi-region public webpage data collection. The appropriate approach should still be selected based on the target website’s rules and the project’s specific data requirements.
If you are preparing to build an AI data collection project, it is better to determine the requirements step by step rather than immediately looking for a specific tool.
First, determine what problem the data needs to solve. Is the goal market research, competitor analysis, price monitoring, or industry content analysis? Different use cases require different data fields.
Next, determine the required data volume and update frequency. Collecting a few hundred records once is very different from collecting large amounts of data every day. You also need to understand how frequently the data changes so that an appropriate update schedule can be established.
Then determine where the data should come from. If a suitable public dataset already exists, it may be sufficient. If the data source is stable and provides an appropriate API, an API may be more efficient. Web scraping can be considered when these options do not provide the information you need.
If webpages are required, further assess the page type, data structure, dynamic content, and potential regional differences. These factors can affect the collection approach.
Finally, select the technical solution and tools based on the earlier decisions. Different tools are designed for different webpage types, data volumes, and technical requirements.
In simple terms, define your data requirements first, identify the data source and collection method next, and choose the specific technology afterward. This approach makes the overall project easier to plan.
Different data requirements call for different approaches.
| Data Requirement | Recommended Method |
|---|---|
| Small, one-time data needs | Manual collection |
| Existing standardized data | Public datasets |
| Stable source with structured data | API |
| Data mainly available on public webpages | Web scraping |
| Webpages with significant dynamic content | Browser automation |
| Data that needs to be collected regularly | Automated data collection |
| Data comparison across different markets | Multi-region data collection |
In practice, a project can also combine several methods. For example, an AI market research project could use a public dataset for basic information, an API for structured data, and web scraping to supplement more recent public information.
The goal is not to choose one fixed method, but to select an approach based on the data source, volume, update frequency, and intended use.
AI data collection is more than simply retrieving content from webpages. It is a complete process that involves defining requirements, identifying data sources, retrieving information, extracting relevant content, cleaning the data, and organizing it for later use.
Different requirements call for different approaches. Small amounts of information can be collected manually, standardized data can come from public datasets, stable sources can be accessed through APIs, while web scraping offers greater flexibility when information needs to be collected from a large number of webpages.
If you are preparing to start an AI data collection project, begin with three questions: What data do you need? Where will you get it? And how will you use it?
Once these questions are clear, you can choose an appropriate approach based on data volume, update frequency, webpage type, and regional requirements, making the collected data more useful for AI analysis and applications.
How does AI collect internet data?
AI can obtain internet data through manual collection, public datasets, APIs, and web scraping. The appropriate method depends on the data source, data volume, update frequency, and intended use.
What internet data can AI collect?
The focus is mainly on publicly visible information, including product information, prices, product resources, industry news, public articles, and market information. The specific data available depends on the source and the project’s requirements.
What AI applications can benefit from web scraping?
Web scraping is suitable for AI applications that need external internet information, including market research, competitor analysis, price analysis, content analysis, information retrieval, and knowledge bases.
What is the difference between APIs and web scraping?
APIs typically return structured data and are convenient to use when the data source is stable and an appropriate interface is available. However, they may be subject to access permissions, request limits, and data coverage. Web scraping offers greater flexibility when specific public information needs to be extracted from webpages. The choice depends on the data source and project requirements.
What should you consider when collecting internet data with AI?
From a technical perspective, consider website structure, data update frequency, access frequency, data quality, and regional differences. From a data-use perspective, follow the website’s rules and pay attention to copyright and personal information protection requirements.
