Boligportal.dk Property Scraper: Extract Danish Rental Listings at Scale

---

What Is Boligportal.dk?

Boligportal.dk is one of Denmark's largest rental property platforms, connecting landlords with tenants across the country. The site hosts thousands of active listings for apartments, houses, and rooms — spanning Copenhagen, Aarhus, Odense, and beyond.

Manually collecting this data is impractical at scale. The Boligportal.dk Property Scraper automates extraction from search result pages, turning paginated listings into clean, structured datasets ready for analysis, integration, or market monitoring.

---

Overview

The Boligportal Property Scraper targets search result pages (SRP) on Boligportal.dk and extracts detailed listing records from each result. It is suited for:

• Real estate analysts tracking rental prices and availability trends
• Proptech developers feeding data into pricing models or aggregators
• Relocation services monitoring listings in specific cities or postal codes
• Academic researchers studying the Danish rental market

Key features include multi-URL support, configurable item limits, and fault-tolerant crawling via ignore_url_failures.

Input Format

The scraper accepts a JSON configuration with three parameters:

{
  "urls": [
    "https://www.boligportal.dk/lejeboliger/?offset=18"
  ],
  "ignore_url_failures": true,
  "max_items_per_url": 50
}

Field	Type	Description
urls	array	One or more Boligportal.dk search result page URLs to scrape. Supports pagination via the ?offset= parameter. Add URLs one by one or in bulk.
ignore_url_failures	boolean	When true, the scraper continues if a URL fails instead of halting the entire run. Recommended for bulk jobs. Default: true.
max_items_per_url	integer	Maximum listings to extract per URL. Useful for controlling dataset size. Default: 20; set higher (e.g., 50) for denser pages.

Tip: To paginate through results, add multiple URLs with incremental offsets: ?offset=0, ?offset=18, ?offset=36, etc.

How to Use

1. Find search URLs — Browse Boligportal.dk and filter by city, price range, or property type. Copy the resulting search page URL.
2. Add pagination — Boligportal uses ?offset=N for pagination (18 listings per page). Add multiple offset URLs to cover more results.
3. Configure the input — Set max_items_per_url based on how many listings you need per page. Set ignore_url_failures: true for bulk runs.
4. Run the scraper — Start the actor and monitor progress in the run log.
5. Export — Download results as JSON, CSV, or Excel for use in spreadsheets, databases, or dashboards.

Best practices:

• Use multiple offset URLs to paginate through large result sets systematically.
• Filter search results on-site (by city, rooms, price) before copying URLs to pre-target your dataset.
• If a page returns no results, verify the URL is a valid search listing page, not a detail page.
