What is Data Scraping? Definition and Best Techniques (2025)

What is data scraping?

Data scraping is a process of leveraging automated tools and scripts to extract unstructured web data. This data is thereafter transformed into business insights that contribute towards predictive models, market research, product positioning, and lead generation.

How is scraping different from data mining

Data mining involves analyzing large historical data to identify patterns, trends, and insights. For example, a company might use web scraping to collect customer reviews from multiple websites and then use data mining techniques to identify common feedback themes.

How is data scraping different from web scraping

Data and web scraping, data crawling, and data mining are often used interchangeably but have distinct implementations and usages.

Web scraping is a part of data scraping that specifically targets large websites. The data is often unstructured and will require cleaning in the future.

How is data scraping different from data crawling

Data crawling, on the other hand, is an automated process used by search engines to discover and index content, structure, and navigation relations between pages using software called crawlers or spiders.

On the contrary, data scraping refers to the automated extraction of data from various sites and digital platforms, including databases, APIs, and spreadsheets.

How does data scraping work?

Data and web scraping tools follow a structured process for extracting and storing relevant information from various digital platforms.

Here's a quick step-by-step guide on how to get started with data collection:

1. HTTP requests are sent by scraping tools to web pages to retrieve data from websites. The HTML code with the underlying DOM (Document Object Model) is used to parse the hierarchical representation of a web page's data and structure.
2. Users can configure the frequency of requests per second to the target website. Advanced tools can trigger 30+ to unlimited requests per second and offer worldwide geo-targeting.
3. Configure any credentials that may be needed to log in to the target website. For example, you could configure your Amazon credentials for Amazon data scraping. And fire the CURL request to check connectivity.
4. The underlying data parsing algorithm can identify HTML, XML, or JSON data, to identify and extract public data. The extracted data can be stored in spreadsheets or local files on the computer. This data, in turn, could be written into an enterprise database.

Applications of data scraping

From market research and price monitoring to lead generation and sentiment analysis, companies rely on scraping to extract valuable insights from the web. But how exactly do businesses use this technology, and why is it so essential? Let’s break down the key applications of data scraping and how it powers smarter decision-making.

Why & how do businesses use data scraping?

Individuals and companies leverage automated web scraping for a range of use cases, including:

Market research

Businesses use web scraping tools to track competitors and extract industry trends and consumer behavior insights. The market research industry was about 54 billion U.S. dollars in 2023 and has grown exponentially by more than 20 billion U.S. dollars since the year 2008.

Innovations such as data scraping are set to revolutionize approaches to navigating the complex global market and ever-changing consumer landscape. For example, retailers and eCommerce platforms use data scraping to analyze competitors, strategies, and customer preferences.

Lead generation

Users can automate contact information collection from directories and social media. Companies that use automated lead generation tools also experience an increase in conversion.

For example, B2B sales teams scrape LinkedIn and directories so that they can gather information about their potential clients.

Also, Report mining using API-based scraping approaches is generally considered since they are generally legal and compliant with the websites' TOS (Terms Of Services).

Web scraping for price and product monitoring

Tracking competitor prices and stock availability to make sure they offer the best in the market. For example, Amazon sellers, travel agencies, airlines, etc., use data scraping tools to adjust their prices according to competitors to offer the best deals for price-sensitive customers.

Consumer sentiment analysis

Businesses leverage data scraping to analyze customer reviews, social media conversations, and forum discussions to understand public opinion about their brand, products, or industry trends. By tracking sentiment shifts—whether positive, negative, or neutral – companies can refine their marketing strategies, improve customer experience, and quickly address potential issues before they escalate.

How to overcome data scraping challenges?

As data scraping becomes well known businesses apply protective strategies to safeguard their data. Scrapers must overcome these challenges while keeping in mind the legal and ethical standards.

• CAPTCHAs – many businesses implement CAPTCHAs on their website to differentiate bots from human users. New-age bot prevention tools include Cloudflare, DataDome, and Akamai with advanced securities. Advanced data scrapers can handle the challenge-response tests.
• Modifying HTML markup – many websites keep changing their HTML structure to keep scapers away, but this can be overcome with AI-powered scrapers that automatically adapt to these changes.
• Rate limiting – certain websites restrict multiple requests within a certain time span. Advanced scraping tools can trigger from 30+ to an unlimited number of requests per minute from their unique IP pools.
• Embedding content in media objects – images, Videos, and PDFs are embedded into the website using tags such as <embed>, <iframe>, etc. This prevents text-based scraping, which can be extracted from non-text elements by OCR (Optical Character Recognition) or AI-powered tools.
• Bot protection solutions – many websites implement bot detection and advanced security measures to block automated scrapers, one can easily overcome this by rotating IPs using residential or mobile proxies such as Smartproxy’s residential proxy and mobile proxy.
• Adaptive security measures – websites implement dynamic protection from scrapers. Headless automation scripts such as Puppeteer or Selenium are often used to replicate humanlike behavior and interactions with JavaScript-heavy pages.
• Advanced bot detection – major websites keep changing their bot detection techniques. Regularly analyzing and adapting to new bot detection techniques is a challenge by modifying request headers, user agents, and interaction patterns, one can overcome this.

Navigating ethical considerations in data scraping

While data scraping could be one of the most sought-after technologies, it's important to follow the ethical guidelines.

For example, scraping personal information or intellectual property without proper attribution could violate the website's terms and conditions, copyright laws, unauthorized surveillance, or automated customer spamming.

Email harvesting for unethical lead generation and spamming has been a concern worldwide, leading to the incorporation of the CAN-SPAM Act, which lays out steep penalties.

Scraping of personal data is often seen as a violation of regulations such as GDPR (General Data Protection Regulation) for EU residents and CCPA (California Consumer Privacy Act), a US law meant to protect the personal data of California residents.

To continue, sending too many automated and unauthorized requests to a website could be termed a brute force attack, resulting in DDoS (Distributed Denial-of-Service). The enterprise application servers and network run out of resource capacity to handle the exponential number of web requests, leading to a total outage and unavailability of services.

So, be mindful while choosing a web scraper that's legitimate and ethically compliant. Popular eCommerce, SERP, social media, and generic scrapers usually follow ethical principles and offer complete transparency with elaborate user guides, documentation, and code samples.
