What is Web Scraping and Who is Using it?Monday, August 27, 2018
What is Web Scraping?
Web Scraping (also called Web Crawling, Data Extraction, Screen Scraping) is the process of extracting data from multiple websites and saving it into local databases, in formats of Excel, txt, CSV and JSON. With the overwhelming data available on the internet, web scraping becomes an essential approach to aggregating Big Data.
Who is using web scraping?
We are going to address this question by looking into different industries and jobs that require web scraping skills. To do this, we've compiled and analyzed job information extracted from job sites, including Indeed, Glassdoor, and LinkedIn.
To see exactly which jobs are using web scraping skills, we take a tech giant (Google) as an example in this research. We scraped and analyzed job postings of Google, to find out which and how many jobs are requiring web scraping skills.
Our findings are shown below. After reading them, you might be just as surprised as we were. If you are interested in the scraping process, you may want to check GitHub Repositories to download the crawlers (running at a free web scraping tool Octoparse) to get the data you want.

Finding 2: Non-tech Jobs Are Requiring Web Scraping Skills
Also based on the information extracted from LinkedIn, we found that non-tech jobs are also including web scraping in their job requirements.
Traditional wisdom has it that most jobs requiring web scraping are tech-relevant ones, like Information Technology and Engineering. There are, however, surprisingly many other kinds of jobs that require web scraping skills as well, such as sales, business development, marketing, human resources, writing/editing, and consulting.
Specifically, we explored web scraping jobs in Google, to find out how many jobs are requiring web scraping skills and what other requirements are besides web scraping.

The ability to compile large datasets is fundamental to Big Data analytics, Machine Learning, and Artificial Intelligence.
