10 Myths about Web Scraping

“Is web scraping legal?” “Are web scraping and web crawling the same things?” You may have such questions when you hear about web scraping. Many people avoid web scraping entirely due to widespread misconceptions about its legality and technical requirements. Let’s separate fact from fiction by debunking 10 myths of web scraping.

Is Web Scraping Illegal?

Myth 1: Web scraping is always illegal and will get you in trouble.

Reality: “Is web scraping legal?” Yes, when done correctly. Web scraping itself isn’t illegal, but problems arise when people disregard websites’ terms of service or scrape protected content without permission.

The legality depends on several factors:

Public vs. private data: Scraping publicly available information is generally legal
Personal data protection: Laws like GDPR affect scraping personal data from publicly accessible sources
Website terms of service: Many sites explicitly prohibit automated data collection
Data usage: How you use scraped data matters legally

According to reports, 2% of online revenue can be lost due to content misuse through web scraping. While no specific laws ban web scraping outright, several legal frameworks apply:

Is Web Scraping Legal in Different Regions?

Is WEb Scraping Legal in US?

Yes, US courts consistently uphold scraping publicly available data when done appropriately. The landmark LinkedIn vs HiQ Labs case confirmed that accessing public data doesn’t violate the Computer Fraud and Abuse Act (CFAA).

However, be cautious with:

Personal data protected by state privacy laws (CCPA in California, CPA in Colorado, VCDPA in Virginia)
Copyrighted content requiring fair use consideration
Data behind logins or password protection
Terms of service violations that can lead to contract breach claims

For business scraping projects, consider forming an LLC to protect personal assets from potential legal risks.

Is Web Scraping Legal in Canada?

Yes for public data, but Canada has stricter privacy protections than the US. The Personal Information Protection and Electronic Documents Act (PIPEDA) governs how personal data can be collected and used.

Key considerations:

Public data scraping is generally permitted for legitimate purposes
Personal information requires explicit consent under PIPEDA
Provincial laws like Quebec’s Law 25 add additional requirements
Cross-border data transfers have specific restrictions

Always check both federal and provincial privacy laws before scraping personal information.

Is Web Scraping Legal in Europe?

Public data scraping is legal, but GDPR creates the world’s strictest framework for scraping personal data from publicly available sources.

Important regulations include:

GDPR requires lawful basis for processing personal data, even if public
Digital Single Market Directive permits data mining for research and innovation
Database Directive protects substantial database investments
National variations across 27 EU member states

UK Post-Brexit: Similar protections under UK GDPR, Data Protection Act 2018, and Computer Misuse Act.

The key difference: EU treats publicly available personal data as still requiring consent or legitimate interest justification, unlike the US approach.

Are Web Scraping and Web Crawling the Same?

Myth 2: Web scraping and crawling are identical processes.

Reality: These terms describe different activities:

Web crawling scans and indexes entire websites systematically, like search engines do. It focuses on discovery and mapping.

Web scraping extracts specific data from targeted webpages. It’s goal-oriented and selective, focusing on particular information like prices, reviews, or contact details.

Can I Scrape Any Website?

Myth 3: Technical ability equals legal permission to scrape.

Reality: Technical capability doesn’t grant legal rights. Consider these restrictions:

Private data requiring login credentials cannot be scraped legally
Terms of Service often explicitly prohibit automated data collection
Copyrighted content requires permission to use
Personal information may be protected by privacy laws

One person can be prosecuted under several laws. For example, one scraped some confidential information and sold it to a third party disregarding the desist letter sent by the site owner. This person can be prosecuted under the law of Trespass to Chattel, Violation of the Digital Millennium Copyright Act (DMCA), Violation of the Computer Fraud and Abuse Act (CFAA), and Misappropriation.

When scraping social platforms like LinkedIn, Twitter, or Facebook, you must understand what data is permissible. Most websites allow scraping services that follow robots.txt guidelines.

Users data protection varies by jurisdiction. What’s legal in one country may violate privacy laws in another.

Do I Need to Know Python When Scraping

Myth 4: Web scraping requires extensive programming knowledge.

Reality: No-code solutions make web scraping accessible to everyone.

Modern free web scraping tools like Octoparse provide preset templates for popular platforms:

Amazon product data
eBay listings
LinkedIn profiles
Twitter posts
Google Maps information

These templates require only keywords or URLs – no coding needed. This democratizes data collection for marketers, researchers, analysts, and journalists.

Can I Use Scraped Data for Anything

Myth 5: Once I scrape data, I can use it however I want.

Reality: Data usage has legal and ethical boundaries.

Legal uses:

Market research and analysis
Academic research
Price comparison
Public information aggregation

Potentially illegal uses:

Selling private contact information
Republishing copyrighted content
Creating competing services with scraped data
Using data for spam or fraud

Always consider the source, type of data, and intended use. Proper attribution and avoiding plagiarism are essential ethical practices.

Are Web Scrapers Always Reliable

Myth 6: Web scrapers work consistently across all websites.

Reality: Scrapers face various challenges:

Websites change layouts and structures
IP addresses may get blocked as suspicious
Geographic restrictions can limit access
Anti-bot measures like CAPTCHAs interfere

To avoid being blocked, it is imperative to know more about how to scrape websites without being blocked.

Can I Scrape Data at a Fast Speed

Myth 7: Faster scraping is always better.

Reality: Excessive speed can cause legal and technical problems.

You may have seen scraper ads saying how speedy their crawlers are. According to them, they can collect data in seconds. But what they don’t tell is that a scalable data request at a fast speed will overload a web server, which might lead to a server crash.

In this case, the person is responsible for the damage under the law of “trespass to chattels” law (Dryer and Stockton 2013). As a result, you, the user of the crawler, might be the lawbreaker who will be prosecuted if damages are caused.

If you are not sure whether the website is available for web scraping and how to avoid causing a server crash while extracting data, please ask the web scraping service providers.

Octoparse is a responsible web scraping service provider that places clients’ needs and satisfaction in the first place. The goal of Octoparse is to help clients get their problems solved and be successful.

Are APIs and Web Scraping Identical

Myth 8: APIs and web scraping serve the same purpose.

Reality: They’re different approaches with distinct advantages:

APIs provide structured data channels with defined access rules. They return data in JSON format but may have limitations on available information.

Web scraping offers more flexibility and customization. It can extract virtually any visible data and interact with websites dynamically.

Many platforms offer APIs (Amazon, eBay, Twitter), but web scraping can access data that APIs don’t provide.

Octoparse has made more effort in building preset web scraping templates. Templates are even more convenient for non-tech professionals to extract data by filling out the parameters with keywords/URLs.

Is Raw Scraped Data Useless?

Myth 9: The scraped data only works after being cleaned and analyzed.

Reality: Raw data can provide immediate insights.

Examples of immediately useful scraped data:

Competitor SEO analysis from search results
Product pricing for market positioning
Social media sentiment monitoring
Real estate market trends

Let’s take Octoparse’s Google Search web scraping template as an example. With it, you can search for an organic search result and extract informatics, including the titles and the meta descriptions about your competitors to determine your SEO strategies.

For retail industries, web scraping can be used to monitor product pricing and distribution. For example, Amazon online shop owners can crawl products under the “Electronic” catalog on Flipkart and Walmart to assess the performance of electronic items on other platforms.

While some applications require data cleaning and analysis, others benefit from real-time raw data.

Is Web Scraping Only for Businesses?

Myth 10: Web scraping can only be used in business.

Reality: Web scraping has diverse applications across sectors:

Academic Research:

Paper and citation analysis
Social media trend studies
Economic data collection

Real Estate:

Housing market analysis
Property value tracking
Investment opportunity identification

Marketing:

Influencer identification
Brand mention monitoring
Content aggregation

Personal Projects:

News customization
Price tracking for purchases
Job market analysis

For instance, students can also leverage a Google Scholar web scraping template to conduct paper research. Realtors are able to conduct housing research and predict the housing market.

You will be able to find YouTube influencers or Twitter evangelists to promote your brand or your own news aggregation that covers the only topic you want by scraping news media and RSS feeds.
