TL;DR · WeSearch summary

The author developed five single-platform web scrapers for Chinese social media platforms, but found that an aggregator combining all five sells more quickly. The aggregator performs parallel scraping, normalizes data, applies sentiment analysis, and deduplicates results across platforms. It commands a higher price by reducing integration effort for customers who need cross-platform brand monitoring.

Key facts

▪The aggregator scraper does not collect new data but orchestrates calls to five existing single-platform scrapers.
▪It normalizes outputs, runs sentiment analysis, and deduplicates mentions across platforms like Weibo, RedNote, and Bilibili.
▪The aggregator charges $0.045 per mention—nine times the price of individual scrapers—attracting buyers due to reduced engineering overhead.
▪Each platform is given a 180-second timeout to ensure partial results even if one fails, improving reliability.
▪Billing occurs once per aggregated mention, avoiding double-charges that would occur with sub-actor calls.

The one that sells fastest is the aggregator that wraps them. #webscraping #python #apify #indiehackers I run a small portfolio of public scrapers on the Apify Store. Most of them are single-platform — one for Weibo, one for Douban, one for Xueqiu, one for RedNote (Xiaohongshu), and so on. They cover the long-tail of Chinese consumer signal that Synthesio and Brandwatch charge $50K/year+ for.
