Project Update: Toward a Complete, Reliable Business Directory

In this project, we are steadily building a complete business directory with a strong focus on data quality, freshness, and operational resilience. This write‑up is anonymous by design and intentionally avoids naming specific sites or technologies. Below is a practical overview of the challenges we solved.

At a Glance

7 Management commands (CLI) covering the full pipeline

8 Data models for sitemaps, pages, snapshots, and contacts

These components form the backbone of discovering, fetching, enriching, and monitoring business listings.

Key Challenges Solved

1) Stability and respectful interaction with websites

- Traffic pacing: dynamic delays and jitter smooth out load to reduce rate limits and soft blocks. - Predictable rotation: scheduled IP rotation after a fixed number of pages; no rotation during manual checks so operators can complete challenges safely. - Graceful pauses: when access challenges (such as additional security checks) appear, the process pauses and allows an operator to resolve them.

2) Handling security challenges

- Reliable detection: clear page signals for additional verification are recognized, even when responses still return success status codes. - Interactive flow: after a manual resolution, the job confirms and resumes, avoiding unnecessary restarts or IP changes while a challenge is active. - Auditable status: each request logs the HTTP status and, after resolving a challenge, logs the follow‑up status as well.

3) Efficient population and clean enrichment

- Sitemap and page processing: automated discovery, selection, and queuing of relevant category, listing, and detail pages. - Snapshots: storing page bodies and content hashes to detect changes, deduplicate, and enable later verification. - Careful enrichment: contact information is extracted and cautiously merged into existing listings without overwriting good data. - Practical dedupe: multiple matching signals minimize duplicates while remaining tolerant to incomplete data.

4) Smarter scheduling with less noise

- Recency focus: we prioritize recently changed listings and limit rechecks to at most once per year per listing. - Status tracking: each listing records the last time its site was reviewed; even “no‑new‑info” outcomes are recorded properly. - Clear operator choices: quick skip/abort options make handling exceptions fast without derailing the whole run.

Outcome: a durable foundation for a full directory

With this pipeline, we can populate and maintain a comprehensive directory: discovering new pages, safely retrieving content, enriching company records, and auditing changes over time. The system runs autonomously by default but puts operators in control when intervention is needed.

What’s next

- Detection tuning: refine challenge recognition using real‑world cases to further reduce false positives. - Reporting: lightweight dashboards/exports for progress, new listings, and enrichment quality. - Quality checks: stronger normalization and heuristics to flag inconsistencies earlier.

Our goal remains a sustainable, well‑maintained business directory that stays up‑to‑date, minimizes noise, and remains comfortable to operate.
