Global search-results scraping that doesn't get blocked
A rank tracker is only as good as the search-results data behind it — and collecting that data at scale is genuinely hard. Search engines actively resist automated access, so reliably fetching results from the right country, language and device, for hundreds of thousands of keywords every day, requires a large, constantly-rotating pool of network infrastructure and sophisticated handling to avoid being blocked. On top of acquiring the pages, the raw results then have to be parsed into clean, structured ranking data across many different search engines and result formats. Nightwatch needed this entire pipeline to be fast, resilient and cost-efficient.
We built Nightwatch's end-to-end search-results collection pipeline in two parts. The first is a distributed proxy-and-orchestration layer that provisions and scales cloud instances across multiple regions on demand, distributes scraping jobs across them with priority handling so urgent work isn't starved, and uses anti-detection browser automation to fetch results reliably from the correct location and device. The second is a SERP parsing engine that turns the raw fetched pages into structured ranking data — positions, URLs, snippets and the many rich SERP features — across all the major search engines and their desktop and mobile variants. Results are persisted efficiently, with structured data in PostgreSQL, raw pages compressed into object storage, and analytics flowing into ClickHouse. The infrastructure uses cost-optimised, preemptible instances and exposes metrics for monitoring throughout.
Nightwatch can collect search-results data globally, at the volume its rank tracker demands, while staying resilient against the blocking that defeats naive scrapers. The distributed, auto-scaling proxy layer keeps throughput high and costs controlled, and the parsing engine produces clean, structured ranking data across many engines and result formats. Together they form the reliable data foundation the entire product is built on.
We treated data collection as two distinct problems. For acquisition, we built an orchestration layer that provisions and scales a proxy fleet across cloud regions, balances scraping jobs across it with priority tiers, and uses anti-detection browser automation to fetch results that look like genuine traffic from the target location. For processing, we built a parsing engine that handles the quirks of each search engine and device variant, extracting positions and the full range of SERP features into a consistent structured form. We paired each storage need with the right system — relational for structured results, compressed object storage for raw pages, and columnar ClickHouse for analytics — and kept the whole pipeline cost-efficient with preemptible instances and instrumented with metrics for reliability.
