First, we’ll explore the role of web scraping in the context of job searching, highlighting how it can empower you to access, filter, and organize job listings from websites like Indeed.
Web scraping, often referred to as web harvesting or web data extraction, is a technique used to extract information from websites. It involves automating the retrieval of data from web pages, which can then be saved, processed, and analyzed for various purposes. Web scraping is a valuable tool in the world of data collection, as it allows you to transform unstructured data on websites into structured datasets that are easier to work with.
Web scraping is achieved using specialized software tools, programming languages like Python, and sometimes with the help of APIs (Application Programming Interfaces). By sending HTTP requests to a website, you can retrieve its HTML or XML content, parse it to extract the data you need, and then store that data for analysis, research, or other applications.
The traditional method of job searching often involves visiting multiple job boards, company websites, and recruitment platforms to find relevant job listings. This process can be time-consuming and overwhelming, especially when you’re searching for opportunities across different locations and industries.
Web scraping plays a crucial role in simplifying and optimizing the job searching process. Here’s how:
Aggregating Job Listings: Web scraping allows you to aggregate job listings from various sources and websites into a single dataset. This means you can access a wide range of job opportunities all in one place, saving you the effort of visiting multiple websites.
Automating Data Retrieval: Instead of manually copying and pasting job details, web scraping automates the data retrieval process. With the right scraping script, you can extract job titles, company names, job descriptions, locations, and more without repetitive manual tasks.
Customized Searches: Web scraping empowers you to customize your job search. You can set up specific search criteria and filters to extract job listings that match your preferences. This level of customization helps you focus on the most relevant opportunities.
Real-Time Updates: By scheduling web scraping scripts to run at regular intervals, you can receive real-time updates on new job listings. This ensures that you’re among the first to know about job openings in your desired field.

Here, you’ll notice the
When interacting with the Crawlbase Crawling API, it’s crucial to understand the response times and how to interpret success or failure. Here’s a closer look at these aspects:
Response Times: Typically, the API response time falls within a range of 4 to 10 seconds. To ensure a seamless experience and accommodate any potential delays, it’s advisable to set a timeout for calls to at least 90 seconds. This ensures that your application can handle variations in response times without interruptions.
Response Formats: When making a request to Crawlbase, you have the flexibility to choose between HTML and JSON response formats based on your preferences and parsing requirements. You can pass “format” query parameter with value “html” or “json” to select the required format.
If you select the HTML response format (which is the default), you’ll receive the HTML content of the web page as the response. The response parameters will be added to the response headers for easy access. Here’s an example response:
If you opt for the JSON response format, you’ll receive a structured JSON object that can be easily parsed in your application. This object contains all the information you need, including response parameters. Here’s an example response:
Response Headers: Both HTML and JSON responses include essential headers that provide valuable information about the request and its outcome:
url: The original URL that was sent in the request or the URL of any redirects that Crawlbase followed.
original_status: The status response received by Crawlbase when crawling the URL sent in the request. It can be any valid HTTP status code.
pc_status: The Crawlbase (pc) status code, which can be any status code and is the code that ends up being valid. For instance, if a website returns an
original_statusof 200 with a CAPTCHA challenge, the
pc_statusmay be 503.
body(JSON only): This parameter is available in JSON format and contains the content of the web page that Crawlbase found as a result of proxy crawling the URL sent in the request.
These response parameters empower you to assess the outcome of your requests and determine whether your web scraping operation was successful.
Additionally, you can extract cookies and headers, set custom user agents, capture screenshots, and even choose geolocation preferences using parameters such as “get_cookies,” “user_agent,” “screenshot,” and “country.” These options provide flexibility and control over the web crawling process. For example, to retrieve cookies set by the original website, you can simply include “&get_cookies=true” in your API request, and Crawlbase will return the cookies in the response headers.

In this section, we will guide you through the process of creating a powerful Indeed job scraper using Python. This scraper will enable you to gather job listings, handle pagination on job search pages, extract detailed information from job posting pages, and efficiently save this data into an SQLite database.
To begin scraping job listings from Indeed.com, we need to understand how to make requests to the website and parse the results. If you visit Indeed’s homepage and submit a job search query, you’ll notice that the website redirects you to a search URL with specific parameters, like this:
Here, we’re searching for Web Developer jobs in Virginia, and the URL includes parameters such as
q=Web+Developer for the job query and
l=Virginia for the location. To replicate this in your Python code using the Crawlbase library, you can use the following example:
from crawlbase import CrawlingAPI
This code snippet demonstrates how to send a GET request to Indeed’s job search page. Once you have the HTML content of the job listing page, you can parse it to extract the job listings.
We could parse the HTML document using CSS or XPath selectors, but there’s an easier way: we can find all of the job listing data hidden away deep in the HTML as a JSON document:
We can use regular expressions to extract this JSON data efficiently. Let’s update the previous example to handle scraping of job listings.
mosaic-provider-jobcards containing structured job listing information in JSON format. It then parses this JSON data, extracting two main components: “results,” which contains the job listings, and “meta,” which contains metadata about the job listings, such as the number of results in various categories. The function returns this structured data as a Python dictionary for further processing.
Indeed’s job search results are typically paginated. To handle pagination and collect multiple pages of job listings, you can modify the URL parameters and send additional requests. To scrape multiple pages, you can adjust the URL’s
start parameter or extract pagination information from the HTML.
scrape_indeed_search function starts by making an initial request to the Indeed search page using the provided query and location. It then checks the response status code to ensure that the request was successful (status code 200). If successful, it proceeds to parse the job listing data from the HTML of the first page.
To handle pagination, the code calculates the total number of job listings available for the given query and location. It also determines how many pages need to be scraped to reach the maximum result limit set by the user. To collect the URLs of the remaining pages, it generates a list of page URLs, each with an incremental offset to fetch the next set of results.
Then it initiate Crawling API request for each of the generated page URLs. As each page is fetched, its job listings are extracted and added to the
results list. This approach ensures that the script can handle pagination seamlessly, scraping all relevant job listings while efficiently managing the retrieval of multiple pages.
Once you have the job listings, you may want to extract more details by scraping the full job posting pages. The job search results encompass nearly all job listing information, except for certain specifics like a comprehensive job description. To extract this missing information, we require the job ID, conveniently located within the jobkey field within our search results:
Leveraging this jobkey, we can send a request for the complete job details page. Much like our initial search, we can parse the embedded data instead of the HTML structure:
This data is tucked away within the _initialData variable, and we can retrieve it using a straightforward regular expression pattern. Here’s how you can do it:
To store the extracted job data, you can use an SQLite database. Here’s an example code of how to create a database, create a table for job Postings, and insert data into it.
This code starts by initializing the database structure, creating a table named ‘jobs’ to store information such as job titles, company names, locations, and job descriptions. The
initialize_database function initializes the SQLite database and returns both the connection and cursor. The
save_to_database function is responsible for inserting job details into this table.
The actual web scraping process happens in the
scrape_and_save function, which takes a job key (a unique identifier for each job posting) and an SQLite cursor as input. This function constructs the URL for a specific job posting, sends an HTTP request to Indeed’s website, retrieves the HTML content of the job page, and then parses it using the
parse_job_page_html function. This parsed data, including job title, company name, location, and job description, is then saved into the SQLite database using the
main function orchestrates the entire process. It initializes the database connection and Crawling API instance, defines a list of job keys to scrape, and runs the scraping and saving tasks for each job key. Once all the job details have been scraped and stored, the database connection is closed.
By following these detailed steps, you can build a comprehensive Indeed job scraper in Python, scrape job listings, handle pagination, extract data from job posting pages, and save the data into an SQLite database for further analysis or use.
