What is Web Scraping?

Web Scraping is the process of extraction of data from a website or webpage. It is an automated method of extracting data into specific datasets using bots. The desired information is collected separately in a new file format.

Once the desired information is scraped through the webpage, it is further used for analysis, comparisons, and verification based on a business’s goals. This is an effective tool that many business owners use to optimize and plan their business operations in a better way.

This process is usually done on a large scale mostly by search engines and captures generic information. The crawlers go through every page on a website rather than a subset of pages.

Thus, when you search anything on the search engine, they use web crawling to find all the relative links based on your search query.

Major Output Difference Between Web Scraping and Web Crawling

While both the Web Scraping and Web Crawling tools deal with data collection, they are unique in their output result. One can noticeably agree that the results generated by both tools are different.

Web Crawling outperforms its functions to typically list URLs. There might be other fields of information but predominantly, URLs are the major by-product.

In the case of Web Scraping, the major output focuses on broader information other than URLs. This might include a study of customer reviews, competitor product star ratings, product price, and other relative outputs.

Challenges For Web Scraping and Web Crawling

Even after being so advanced and effective in the relative data extraction field, both Web Scraping and Web Crawling tools face great challenges. These challenges act as a barrier in the working and procedure of these functions. Following are some of the challenges that hinder the process –

Blockage in Data Access

Many websites today use anti-scraping and anti-crawling policies which makes it quite challenging for businesses to do the job.


Performing data crawling or scraping at a large scale can be resource-intensive. Resources include proxies, engineers, etc. So, companies operating on a large base will require high-cost inputs to continue the process.

IP Blockage

Websites that can be easily targeted can easily provide you with the target data sets. But there might be some websites(google, amazon, indeed, etc) that restrict IP addresses to prevent them from performing any web scraping or crawling. This could be a major challenge for the process performers.

Crawler Trap

A Crawler trap misguides web crawlers and scrapers to fetch malicious pages such as spam links. The crawler works on the malicious links and gets stuck in the dynamically generated spam links. This way it enters an infinite loop and gets trapped.

I have explained the challenges of web scraping in detail here. Do check it out!!


To sum it up, Web Crawling is the data indexing process while Data Scraping is a data extraction process. Data Scraping helps businesses with the information they need to optimize their business functions.

It is relatively used for a targeted and personal approach to getting a hold of real-time data. While in the case of Web Crawling the bot or crawlers scan the information present on the web pages to identify its URL for indexing and further ranking purposes.

But the common part with both of them is IP blocking. To overcome this you should use Web Scraping API which can help you overcome any blockage and will help you maintain your data stream

I hope now you have a good idea of the difference between the two. Please do share this blog on your social media platforms. Let me know if you have any scraping-related queries. I would be happy to help you out.
