Job hunting has come a long way since the days of scouring newspapers and pounding the pavement. These days, the vast majority of job openings can be found online, scattered across thousands of different company websites, job boards, and staffing agency pages.
While this wealth of digital job listings has made it easier than ever for job seekers to access a wide range of opportunities, it has also introduced a new challenge: information overload. With so many job postings to sort through, it can be overwhelming and time-consuming for job hunters to find the most relevant openings for their skills, experience level, and location.
This is where job aggregators come in. Job aggregators are websites that collect and centralize job listings from many different online sources, providing job seekers with a one-stop shop to search and browse through thousands of curated job openings.
Some of the most popular job aggregators include:
What Exactly Is a Job Aggregator?
A job aggregator is a website or platform that compiles job listings from various sources across the web into a single, searchable database. Job aggregators typically gather postings from employer websites, job boards, classified ads, and staffing agency websites.
The goal of a job aggregator is to save job seekers time and effort by eliminating the need to visit dozens of different sites to find job openings. Instead, they can simply enter their search criteria into the job aggregator and instantly access a curated list of relevant opportunities aggregated from many sources.
Job aggregators don‘t post jobs directly or get involved in the hiring process. They simply re-post job listings that have already been published elsewhere online. Job seekers can click on postings they are interested in to be taken directly to the original source to learn more and apply.
However, job aggregators go beyond just collecting links. They typically standardize the format of the job data they aggregate and enrich it with additional classification and tagging (e.g. categorizing jobs by industry, seniority level, required skills, etc.). Many also offer powerful search filters and email alerts to help job seekers quickly pinpoint the most relevant opportunities.
Some of the key benefits job aggregators provide include:
- Saving job seekers significant time and effort by aggregating listings in one place
- Surfacing job opportunities job seekers may have otherwise missed
- Making it easy to compare job openings side-by-side
- Providing more comprehensive search results than any single source
- Offering tools to help job seekers find the most relevant openings faster
In addition to benefiting job seekers, job aggregators can also be valuable for employers. Having job openings distributed to aggregators exposes them to a larger audience and drives more qualified applicants. Some job aggregators also sell premium placement or featured listing upgrades to employers looking to get even more visibility for their job postings.

Adzuna: This aggregator collects job ads from over 1000 sources and offers unique features like "ValueMyResume" to predict earning potential and a career personality test. It also provides detailed labor market data and salary stats.
While these established players dominate the job aggregation space, there are also opportunities for entrepreneurs and organizations looking to build niche job aggregators focused on specific locations, industries, or job types.
However, building a successful job aggregator requires having comprehensive, up-to-the-minute job listings data – which is where web scraping comes in.
How Web Scraping Powers Job Aggregators
The core asset of any job aggregator is its database of job listings. The more comprehensive and current this database is, the more useful the aggregator will be to job seekers.
However, manually gathering and importing job listings from hundreds or thousands of different sources is simply not feasible. Not only would it require a huge amount of time and human resources, but the listings data would quickly become outdated as openings are filled and new jobs get posted.
This is why web scraping is an essential tool for job aggregators. Web scraping refers to the automated process of using bots to systematically extract large amounts of data from websites. A web scraper can be programmed to automatically visit specified job boards and company sites, identify and extract new and updated job postings, and pull that data into a structured database.
Web scraping allows job aggregators to automate the arduous process of job data collection. Instead of manually copying and pasting job ads, aggregators can use web scrapers to instantly gather job listings from thousands of online sources and continuously update their database as new openings appear.
Some of the key ways web scraping supports job aggregators include:
- Drastically reduces the time and effort required to build a comprehensive job database
- Enables the aggregator to provide the freshest, most up-to-date job listings
- Allows scraping on a continuous schedule to constantly add new job postings
- Extracts job data in a structured format ready for importing into the aggregator‘s database
- Can be easily scaled up as the aggregator expands to new markets or sources
In short, web scraping is what allows job aggregators to operate at scale by automating the otherwise impractical task of manually aggregating job listings across the web. Without web scraping, it would be nearly impossible to build a truly comprehensive, useful, and current job listings database.
How to Scrape Job Postings from the Web
If you‘re looking to build your own job aggregator, the first step is gathering comprehensive job postings data from relevant websites. Here is a simplified overview of how the job listings web scraping process works:
Identify the websites you want to scrape job postings from (job boards, company sites, etc.)
Determine the specific data points you want to collect for each job posting (job title, company, location, job description, application URL, etc.)
Use a web scraping tool or write a script to automate the process of visiting the target websites, locating the desired data fields, and extracting the data
Set up the web scraper to run on a continuous basis to capture new job listings as they are posted
Export the scraped job data into a format that can be imported into your database
While it is possible to write your own web scraping scripts from scratch if you have coding knowledge, many job aggregators choose to utilize no-code web scraping tools that simplify the process. These tools provide a user-friendly interface for specifying the target websites and data fields to extract without requiring any programming.
For example, here is a simple 4-step process for scraping job listings using Octoparse, a leading no-code web scraping tool:
Enter the URL of the job board or company site you want to scrape into Octoparse‘s built-in browser.
In Octoparse, use the "auto-detect web page data" tool to identify the data fields you want to collect for each job listing (job title, company name, location, etc.)
Set up the scraping workflow in Octoparse to paginate through all search results and extract the specified job data fields. You can run your scraping task locally or in the cloud.
Export the scraped job data in your preferred format (CSV, JSON, etc.) or set up an API integration or scheduled exports.
Using a no-code tool like Octoparse, even those without a technical background can easily scrape job postings from multiple websites. However, there are a few potential challenges to be aware of when scraping for job aggregation:
Some websites may attempt to block scraping activity, so choose a web scraping tool that offers workarounds like IP rotation and headless browsers.
Job postings may not always have a standardized format across different websites. You may need to set up separate scraping workflows for each site and then standardize the data afterwards.
Scraped job data may contain duplicates that need to be filtered out before adding the records to your aggregator‘s database.
With the right tools and approach, these common web scraping obstacles can be overcome. Once you have a steady pipeline of job listings flowing into your database via web scraping, you can start exploring other ways this data can enhance your job aggregator platform.
Additional Applications of Job Listings Data for Aggregators
While the core function of a job aggregator is to collect and display job openings to job seekers, there are many other ways aggregators can leverage web scraped job data to provide additional value, such as:
Analyzing trends in job titles, skill requirements, and hiring industries to produce labor market insights
Providing salary estimates for different job types based on aggregated compensation data
Identifying companies that are actively hiring for certain roles or in specific locations
Powering personalized job recommendations to surface more relevant listings to each user
Estimating job fill times based on how long postings remain active before being removed
Enhancing job search by extracting relevant keywords from job descriptions to improve search relevancy
By thinking creatively about all the ways job postings data can be sliced, diced, and applied, job aggregators can differentiate themselves and provide unique value to job seekers and employers alike.
The Future of Job Aggregation and Web Scraping
As online job listings continue to proliferate across the web, the need for job aggregators that can collect and organize this data will only grow. Web scraping will remain an indispensable tool for job aggregators looking to build comprehensive, up-to-date job listings databases efficiently and cost-effectively.
Advancements in AI and machine learning may also unlock new opportunities for job aggregators to extract additional insights and value from job postings data in the future. Some exciting possibilities on the horizon include:
Using natural language processing to automatically categorize job listings and extract structured data fields even from unstructured job descriptions
Leveraging AI to identify patterns and predict job market trends on both the supply and demand sides based on aggregated postings data
Applying machine learning algorithms to job descriptions and user behavior to match job seekers to openings they are most qualified for
As the world of online job search continues to evolve, it‘s clear that web scraping will play a pivotal role in helping job aggregators innovate and thrive. By harnessing the power of web scraped job data, aggregators can build data-driven platforms that effectively connect job seekers and employers at scale.
