Tips for Best Results

Start with Known Working Search URLs

• Use real Immowelt search result URLs for the most predictable output.
• Test with one URL first, then scale to multiple URLs.

Tune Collection Size

• Start small (20-50) for validation.
• Increase results_wanted once output quality is confirmed.

Use Proxy Configuration for Production

• Residential proxy groups are recommended for larger or repeated runs.
• Keep retry and scheduling strategy consistent for stable pipelines.

Keep Input Focused

• Use specific propertyType and location values to reduce noisy results.
• Split broad monitoring into multiple targeted runs.

Frequently Asked Questions

How many listings can I collect?

You can collect up to your configured results_wanted limit, constrained by available source results and run conditions.

Can I run multiple searches in one execution?

Yes. Use startUrls to process multiple Immowelt search pages in a single run.

Why are some fields sometimes empty?

Some listings do not expose every field. Missing values are returned as null or empty arrays.

Is proxy configuration required?

Not always for testing. For production or repeated monitoring, proxy usage is recommended for reliability.

Can I schedule this actor?

Yes. You can schedule runs in Apify to collect fresh listing data automatically.

How do I avoid duplicate records?

Use listingId or url as your primary deduplication key in downstream systems.
