Web Scraping Of Job Postings | A Complete Guide | JobsPikr

Introduction to Web Scraping of Job Postings:

Web scraping, also known as data scraping, refers to the process of retrieving data from a website and storing it in an accessible format on your local computer or the cloud. Choosing to manually copy and paste data will take days because most of the data is displayed using a browser. This process is automated by a web scraper which only takes a few seconds to complete the task.

In the web scraping industry, job data is considered important information. According to Gallup’s 2017 State of the Workplace Report, about 51% of workers are looking for new jobs in developed countries while 58% are looking for jobs online. This means that the online job market is huge and being able to keep track of the data can bring you positive results if you are a job aggregator, a company looking to hire or just want to be hired.

Web Scraping of Job Offers:

There are two main sources of job data:

  1. Work aggregator sites (Indeed, Monster, etc.)
  2. Job offers from each company

Task aggregator sites are more difficult to scrape because they use anti-itching techniques such as Captcha, IP blocks, honey pot traps, etc. to protect their information from scraping robots. However, job vacancies from a business are much easier to scratch. But each company uses a different interface, which means that you will have to use a different crawler for each. This is not an easy task, as it is expensive and difficult to maintain robots when a website undergoes changes.

These are the tools that you can choose from when you delete job postings from the web.
