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. This situation calls for a thorough policy analysis to understand the implications and potential improvements in their API accessibility and maintenance practices.
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 an API key: you usually need to register to become Glassdoor's API Partner and obtain an API key or token for authentication.
- Accepting use policy: users must agree with Glassdoor's terms of use agreement.
- 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.
🌟 What kind of data can you scrape from Glassdoor?

⚖️ Legal considerations of scraping Glassdoor job data
It's generally legal to scrape publicly available data like company reviews and job listings. However, it is important to ensure compliance with Glassdoor's terms and conditions. Agreeing to Terms and Conditions is an important concept to be familiar with for everyone who's trying to web scrape or bypass the Glassdoor login wall.
🥾 How to scrape Glassdoor company reviews and other data
Selecting the right tools is the heart of any successful scraping project. For Glassdoor, this involves finding and choosing a web scraper advanced enough to navigate the complexities of the site. So would you have to build one? 🤔 Tools like Playwright or Selenium are popular choices among developers due to their ability to automate browsers and mimic human interaction on the website (such as visiting a website and copying data from it). However, creating a scraper like that requires a certain level of coding knowledge.
This is where Apify Actors come into play. These serverless cloud programs are designed to perform web scraping and automation tasks on any website. On a marketplace like Apify Store, you can search and find more than 1600 of them, with the majority made by independent developers. Advanced Glassdoor Scraper is just one among many pre-built Actors that can save time and effort in the scraping process. So let's see how we can use it.
Step 1. Find the Advanced Glassdoor Scraper
To start with Glassdoor scraping, you need to find a good web scraping tool first. Visit the Advanced Glassdoor Scraper page on the Apify Store and click the Try for free button. You can find other data extraction tools there that able to scrape data from Glassdoor but we'll be demonstrating the process on this one first.
Create an Apify account by signing up for free using your regular email address, Gmail, or GitHub. You'll find yourself in Apify Console – your workspace for any web scraping tool and storage for the data it extracts.
Step 2. Add Glassdoor page URLs
Your web scraping project setup is simple. Go to any browser and navigate to the glassdoor.com web page. Then copy the URL of that page and paste it into the Start URLs field. You can add as many Glassdoor URLs as you want and of a different variety: reviews, company pages, job postings.
What the scraper is going to do is go to every Glassdoor page you've added and scrape data from it. If you don't want to use the fields, you can always use the JSON editor and import a JSON file as your input. You can also use other fields such as Search keyword but for our example, it's not necessary.
Step 3. Begin scraping Glassdoor data by clicking Start ▷
Once you are all set, click the Start button. You will notice that your task will change its status to Running 🏃♂️. It will be just a minute before you see the status switch to Succeeded ✅ and you can see the results of data extraction.
Step 4. Export the data scraped from the Glassdoor
When the status changes to Succeeded ✅, you can check the results in the Output and Storage tabs. Before exporting, you can preview the dataset in a table or see how it would look in other formats.
Step 4. Export the data scraped from the Glassdoor. Here are examples of scraped interviews and reviews.
After you scrape data, you can export the data as a CSV file or any other format like JSON, Excel, HTML or XML. We can also share the scraped Glassdoor data directly via an API.
