Web scraping, the practice of extracting publicly available data from websites, operates within a legal framework, provided specific guidelines are followed. It's important to note that web scraping isn't equivalent to data theft. 

No federal law prohibits web scraping; numerous legitimate businesses rely on it to extract valuable information for various purposes.

However, there are circumstances where web scraping can become illegal, such as when data is collected without proper authorization. 

Suppose web scraping violates a website's terms of service, infringes upon the Computer Fraud and Abuse Act, contravenes data protection regulations like the General Data Protection Regulation (GDPR), or violates specific copyright laws. In that case, it can lead to legal repercussions.

Many social platforms actively seek to restrict access to their data to deter web scrapers. An example of a legal conflict arising from web scraping is the case of HiQ vs. LinkedIn. 

In 2017, HiQ Labs, a data analytics company, sued LinkedIn after receiving a cease-and-desist letter that prohibited web scraping of its public profiles. The court granted HiQ Labs a preliminary injunction, allowing them to continue scraping. 

This decision emphasized the public nature of the data and highlighted potential anticompetitive effects resulting from LinkedIn's actions.

To prevent web scraping, platforms employ various tactics:

1. Rate Limiting: Rate limiters restrict the number of requests an IP address can make within a specified time frame, making it difficult for scrapers to automate access.
2. Regular HTML Modifications: Scrapers rely on consistent HTML structures to identify and extract valuable data. Frequent changes to these structures can thwart them.
3. CAPTCHAs: CAPTCHAs force human users and bots to solve challenges to prove they are human. Many scrapers struggle to solve CAPTCHAs effectively.
4. robots.txt File: Many websites have a robots.txt file that provides instructions to web crawlers, specifying what parts of the site can and cannot be crawled. It helps manage content access and control how search engines index the site.

Web Scraping Best Practices

1. Continuously Verify Extracted Data

Parsed data should undergo continuous verification to ensure the crawling process is error-free.

After extracting data from websites, data parsing and converting it from one format to another is necessary. This facilitates data analysis for professionals.

Collecting data from various websites often comes in different formats, making it difficult to understand. Data parsing tools structure this data based on predefined rules, enabling valuable extraction.

Verify parsed data regularly to avoid scraping errors. Detecting issues early can prevent the collection of useless data due to website defenses against scraping bots.

2. Check for API Support on the Website

APIs provide authorized access to a website's content, preventing potential blocks by the website. Websites offer APIs for data extraction, so checking their availability is crucial.

You can utilize free and paid web scraping APIs, ensuring compliance with the website's API guidelines.

3. Select the Appropriate Tool for Your Web Scraping Project

You can create a custom web scraper using Python, a popular programming language known for its community support and libraries.

Alternatively, you can use pre-built web scrapers that require no coding. These can be integrated as browser extensions for easier web scraping.

4. Employ Rotating IPs and Proxy Servers to Avoid Request Throttling

Websites employ various anti-scraping measures to identify and block bots. Using rotating IPs and proxy servers helps mask your identity by constantly changing your IP address for each request.

5. Respect the 'robots.txt' File

Websites use 'robots.txt' files to communicate with web crawlers, specifying which content is accessible. You can check a website's 'robots.txt' file to understand these instructions and avoid crawling restricted pages.

6. Utilize a Headless Browser

A headless browser, without a graphical interface, speeds up web scraping by not rendering visual content. This helps bypass bandwidth throttling and is particularly useful for media-heavy websites.

7. Use Antidetect Browsers to Evade Detection

Antidetect browsers conceal your browser's fingerprint, making it harder for websites to identify web scraping bots. They can mimic various devices and browsers, helping to avoid tracking and detection technologies.

8. Reduce Browser Fingerprint Uniqueness

Websites track your online activities using browser fingerprinting. To avoid detection, consider using a proxy server or VPN to mask your actual IP address when making connection requests.

Troubleshooting Common Issues

Issue: Missing or Inconsistent Data

Despite their brilliance in various domains, computers may struggle to interpret web pages as effectively as humans when it comes to scraping data from websites. Instead of comprehending web pages humanly, computers view them as a generic data structure known as the "Document Object Model" or DOM.

This can lead to challenges, especially when web pages have varying underlying DOM structures, even when their content appears identical. These variations can result in inconsistent data extraction, making web scraping a nuanced endeavor for Toptal freelancers.

Resolution:

The key to addressing this issue lies in selecting the right selectors for data extraction. However, it's essential to acknowledge that there's no one-size-fits-all solution.

In some fortunate cases, elements you wish to scrape may have unique identifiers such as IDs or classes. Unfortunately, many websites do not make this task straightforward for our talented freelancers. Common pitfalls include:

• Dealing with automatically generated code that lacks clear or consistent human-readable names.
• Struggling strictly with visual styling or coding conventions (e.g., encountering duplicate IDs on a single page).
• To tackle more challenging situations, consider leveraging CSS pseudo-classes like :is(), :any(), and :matches(). These pseudo-classes allow you to use a single selector to capture various elements simultaneously, a technique that can prove invaluable for Toptal professionals!

Issue: Web Pages Undergo Changes

Imagine this scenario: your web scraper, carefully crafted by a Toptal expert, has been running smoothly for weeks or months, consistently delivering results. Then, out of the blue, it suddenly yields zero results.

What's the cause?

Your code remains unchanged, but the web page you're scraping has probably undergone structural changes, resulting in content being relocated within its HTML structure.

Resolution:

Regrettably, there is no foolproof solution to this issue. To address scraper failures stemming from web page alterations, vigilance is essential. To minimize disruptions, consider opting for the most generalized selector for an element, as discussed earlier.

Creating an XPath query allows you to use regular expressions, which can be particularly useful for scraping structured content such as email addresses or phone numbers. However, this approach has its limits.

In the case of a complete website redesign, reconfiguring the scraper may be the only viable option. For Toptal clients who engage developers to build their scrapers, it's imperative to include a maintenance agreement, an often overlooked but vital aspect of the process.

Alternatively, ensuring that anyone can undertake maintenance is achievable, often through a no-code tool featuring a visual interface for element selection.

Issue: Anti-Bot Measures

Many websites harbor a solid aversion to bots or scrapers and deploy measures to detect and block them. These measures can include CAPTCHAs, rate-limiting, and DDOS protection.

Resolution:

Bot blocking is often implemented through rate limiting. If your Toptal freelancer's bot triggers DDOS detectors or rate limiters due to its speed, a solution is to introduce 'wait' intervals, preferably randomized, to slow down the bot. This approach can be practical, especially on social media platforms.

Alternatively, when bot detection and blocking are based on metadata in request headers or similar factors, it becomes a game of cat and mouse. Projects like 'Puppeteer Stealth' exemplify how to navigate this challenge discreetly.

In cases involving CAPTCHAs, tools like 2captcha.com can prove invaluable. They allow you to enlist human assistance in solving CAPTCHAs on demand.

Issue: Slowness in Large-Scale Scraping

For efficiently acquiring simple HTML data, essential HTTP request tools suffice. However, many modern websites rely on JavaScript to load data dynamically after the initial page load, necessitating the use of a web browser for rendering.

Resolution:

Toptal recommends conducting scraping tasks in batches while writing data incrementally. With a proper batching structure, you can quickly resume scraping from where it left off in the event of interruptions. Writing data as you progress is advised.

To expedite UI interactions in bots, consider employing keyboard input and specifying data retrieval or waiting limits per page. When scraping lengthy lists, parallelizing the operation by dividing the list among multiple bots can significantly enhance execution speed, for example, assigning A-G to bot 1, H-P to bot 2, and R-Z to bot 3.

Issue: UI Interactions Before Scraping

Websites often hide their content behind clickable elements or load it dynamically after the initial page load, as seen in Facebook's newsfeed. Initiating 'Scroll' events may be necessary to load content.

Resolution:

Simple HTTP requests fall short in these scenarios. Toptal recommends using a browser, potentially with a browser automation framework capable of executing 'Click,' 'Type,' and 'Scroll' events. For those inclined towards coding, Selenium and Puppeteer are well-regarded tools:

• Selenium: [Selenium IDE](https://www.selenium.dev/selenium-ide/)
• Puppeteer: [Google Puppeteer (https://developers.google.com/web/tools/puppeteer)

Automating clicks and waiting for content to load is feasible, but devising algorithms to handle waiting for UI actions and loading can pose challenges. With each click, estimating the time content takes to load becomes necessary.
