Practical web scraping tutorial for how to extract all the data from Glassdoor without login: job listings, company data and reviews, salary information, and other public data, and export it as a CSV file, HTML, JSON, Excel, or XML.
When it comes to job search and company insights, the Glassdoor website stands out. Employee reviews, salaries, interview afterthoughts, company overviews, job postings – they've got it all. However, extracting this data manually is daunting. Here’s where web scraping comes into play, allowing you to bypass the Glassdoor login and access data efficiently and legally. In this article, we'll learn about the limitations of Glassdoor API, see a web scraping tool called Glassdoor Scraper in action, and even discover how to build a Glassdoor web scraping API of your own.
🤖 Is there an official Glassdoor API?
If you look at the Glassdoor website, there's plenty of data there that could be useful for any job project. Typical categories of Glassdoor data include:
Company reviews and ratings: detailed reviews and ratings about companies given by current and former employees.
Salary reports: information on salary and compensation for various positions within companies.
Interview questions and reviews: details about interview processes, questions asked, and feedback on the interview experience.
Job listings: data about current job openings, including roles, job title, locations, and job descriptions.
Conditions for use
While Glassdoor does seem to provide a public Glassdoor API, you'd expect it to allow access to at least some range of its public web data. The current free Glassdoor APIs such as Job Actions API or Companies Actions API seem accessible but in reality, are heavily undermaintained. On their official Help page, Glassdoor says they do not freely make API partnerships available.
The official Glassdoor Developer documentation that there is on this topic also seems undermaintained. However, it's enough to see that there will be some conditions for using the Glassdoor API such as:
Registering and getting anAPI key: you usually need to register to become Glassdoor's API Partner and obtain an API key or token for authentication.
Attribution: proper attribution to Glassdoor is required if you're displaying the data publicly.
And even if you fulfill those conditions, here are some typical limitations of getting data through official APIs that you might encounter:
Basic knowledge of programming: you would need to figure out of to use the API key and token as well as how to send the right requests.
Rate limiting: the API may have restrictions on the number of requests you can make in a certain time frame to ensure server stability.
Access to data: some data might be restricted based on user privacy or company policies.
API versioning: features and accessible data might vary between different versions of the API, and newer features might not be available in older versions.
Considering these limitations and extra conditions, web scraping comes up as a practical alternative to accessing Glassdoor data.
🦾 What is web scraping?
In short, web scraping is the process of extracting data from websites. An automated tool for web scraping (such as Glassdoor Scraper) can visit a web page and reformat displayed data into a separate database. The process essentially ‘scrapes’ the target information off of the website (the Glassdoor website in our case) and makes it readable and reusable.
Both job seekers and employers are looking to extract data such as company information or reviews in a fast and organized way. And if the official Glassdoor API seems too big of a hassle to deal with, web scraping on the other hand would allow anyone to access public Glassdoor data without an account.
