Web Scraping Vs Web Crawling

Web scraping vs web crawling is two different methods for collecting data from the web. One method involves manually browsing web pages and collecting data, while the other is automated and requires zero infrastructure. A major advantage of web scrapers is that they enable you to filter data based on certain criteria, which can save you a significant amount of bandwidth and time.


Web scraping is an excellent way to extract data from the web. It is cost-effective and highly accurate. There are many web scraping solutions that can save you a great deal of time and bandwidth, and they are 100% automated. In addition to saving you time, you can also select a specific data point to scrape.

When comparing web scraping with web crawling, it is important to consider the level of complexity. Scraping can be performed manually or using only a crawling agent. Using a scraper allows you to skip the extra work and expense of a complex system. If you’re working with more complex data extraction projects, automation is essential. While hiring temporary staff is necessary for some tasks, such as checking website content and performing analysis, you can automate these tasks with simple scripts that run on Apify’s platform.

Data scraping is very effective for companies working in the eCom space, where it’s crucial to regularly perform market analyses. This is done by gathering relevant data sets, including pricing, reviews, inventory, and special offers. Data collection is also important for brand protection, as it helps identify potential cybercriminals and keep track of their activities. Web scraping services also eliminate human error, ensuring 100% accuracy of the data collected.

Protection from theft

The difference between web scraping and web crawling is that web scraping is done for benign purposes, such as organizing large amounts of text. On the other hand, web crawling is done for more harmful purposes, such as data theft and targeted attacks. Some examples of web scraping include collecting email addresses to spam lists, gathering competitive intelligence, republishing content, and publishing comparative pricing. These activities can have a negative impact on a business. For example, a competitor may be scraping your website in order to gather competitive intelligence, or your competitors may be scraping your content for unauthorized use.

However, there are ways to protect your data from scraping. If you’re worried about your content being used without your permission, you can limit the number of requests made by a particular IP address. This will prevent anyone from making malicious requests to your website and will protect your business from potential financial damage.

Alternatives to point-and-click tools

There are many different types of web scraping tools available for your needs. Some are free, while others are paid and require programming skills. Most are small and easy to use, but they often don’t have the power to handle high volumes of websites. If you need a lot of data, you’ll want to use a full-service web scraping provider. While web scraping tools are great for smaller projects, programming can give you a lot of flexibility and get better results.

If you’re looking for a web scraping tool without the complexity of coding, consider Hevo, which allows you to live monitor data flow and develop web scrapers without writing any code. ParseHub is another good option that lets you choose and store data from different websites. Both programs have desktop clients for Windows, Mac OS, and Linux.

Octoparse is a web scraping tool with a visually intuitive interface. This tool allows you to select various fields from a website with a single click, and it supports dynamic and static websites. The software can scrape data using AJAX, JavaScript, and cookies. It is available for Windows, and includes a free trial.

Alternatives to DOM parsing

If DOM parsing is not what you’re looking for, there are a few alternatives. These tools are all similar, but have some differences. One of these alternatives is JSDOM, which is a pure Javascript implementation of the DOM. It makes scraping HTML websites easy, enables interaction with websites, and is fast. It also has an API for fetching URLs and manipulating data.

These libraries support a number of DOM-based web scraping functions, including XPath and CSS selectors. Moreover, they come with javascript support and user agent mocking. Both of these libraries have their own advantages and drawbacks, but are both suitable for dynamic websites.

Another alternative is Puppeteer. It provides a high-level API to control Chrome. This makes it a preferred choice of Javascript developers for web scraping. However, it is important to note that Puppeteer is not a programming language. It is a server runtime that uses Javascript as its primary programming interface. For more information, read the Puppeteer tutorial.
