Is Web Scraping Legal? (Legal Analysis)
What Is Data Scraping?
Data scraping is the automated process of extracting large amounts of data from websites.
It involves:
- using software tools or scripts to access and gather information from web pages, and
- then storing that data in a structured format for further analysis or use
Here’s a step-by-step explanation of how data scraping typically works:
1. Identification of the target website
The first step is to identify the website or web pages from which you want to extract data. This could be any website that contains relevant information you're interested in.
2. Choosing the scraping tool
Once you’ve identified the target website, you need to select an appropriate scraping tool or library that will enable you to automate the data extraction process.
3. Analyzing the website structure
Before scraping the data, it’s important to understand the structure of the target website.
This involves examining the HTML code of the web pages to identify the specific elements (tags, classes, or IDs) that contain the desired data.
Inspecting the website’s source code or using browser developer tools can help in this process.
4. Writing the scraping code
Once you have a good understanding of the website’s structure, you can start writing the scraping code.
This typically involves using the chosen scraping tool and its associated programming language (e.g., Python) to:
- navigate through the website
- locate the desired data elements
- extract the relevant information
5. Handling anti-scraping measures
Some websites implement measures to prevent or limit scraping activities, such as:
- CAPTCHAs
- IP blocking
- rate limiting
To overcome these obstacles, additional techniques like using proxies, rotating user agents, or incorporating delays between requests may be necessary.
6. Storing the scraped data
After successfully extracting the data, you need to store it in a suitable format for further use or analysis.
This could involve saving the data in a structured format (e.g., CSV, JSON, or a database).
7. Regular maintenance and legal considerations
It’s important to note that data scraping may raise legal and ethical concerns.
Why?
It’s because some websites prohibit or restrict scraping activities through their terms of service.
Therefore, review the website’s policies and consider the legality and ethical implications before proceeding with data scraping.
Additionally, websites frequently update their structure or employ anti-scraping measures. So, periodic maintenance of the scraping code may be necessary to ensure it continues to function properly.
Data scraping can be a powerful tool for various purposes, such as:
- market research
- competitive analysis
- content aggregation
- price comparison
- sentiment analysis
However, it’s crucial to conduct scraping activities responsibly and within the bounds of the law and website policies.

Google And AI Technology
At the 3-day 2018 Google I/O conference (May 8-10) at the Shoreline Amphitheatre in Mountain View, California, an announcement was made regarding Google Research.
According to TechTarget, Google Research, the company’s research and development department for its artificial intelligence (AI) applications, was rebranded and now called Google AI.
Through Google AI, the company will develop and upgrade its Google products (e.g., Google Search, Google Assistant, Google, Google Maps, etc.) and conduct research work in various fields, including:
- robotics
- deep learning
- machine learning (ML)
Per Cointelegraph, Google recently updated its privacy policy because it now decided to use, whenever it deems suitable, data available in public for its AI-related activities.
Specifically, Google will use, as indicated on its revised privacy policy:
- “information . . . publicly available online”
- “other public sources”
In other words, when people upload something online, Google may use itto develop its AI systems.
For its AI data scraping plans, which could compromise people’s personal information, it’s no surprise to learn that Google is now being sued for it.
Reuters reported that on July 11, eight people went to a courthouse in San Francisco and filed a class-action complaint against Google.
In the said lawsuit, based on a copy of the complaint, the plaintiffs enumerated 10 violations allegedly committed by Google.
In a released statement, Ryan Clarkson, the attorney of the plaintiffs, said:
“„Google does not own the internet . . . our creative works . . . our expressions of our personhood, pictures of our families and children, or anything else simply because we share it online.- Attorney Ryan J. Clarkson
In June 2023, the Malibu-based Clarkson Law Firm sued (same lawsuit) OpenAI, the one co-founded by Elon Musk and behind ChatGPT.
