Recurring Data Collection
Run scheduled extraction cycles to capture public data at consistent intervals.
Applications
Longitudinal Trend Analysis with Historical Public Data
Track changes over time using recurring public data collection to support investigative series and long-term research.
Overview
Capture Data At Regular Intervals
Longitudinal Trend Analysis focuses on recurring collection of publicly available data to build time-series datasets. Instead of one-time snapshots, data is captured at regular intervals so research and journalism teams can track changes across entities, markets, policies, and activities over time. These structured historical datasets support investigative series, trend reporting, and pattern validation.

TESTIMONIALS
Here's what our customers say about us
I worked with Grepsr to undertake a one-time extraction of data through web scraping for references made to keywords across four websites of Multilateral Development Banks. Grepsr scraped vast volumes of data over 65,000 PDF documents and provided final files of scraped data in the format I desired. This data scraped by Grepsr will have a profound impact on my research.
Team was able to extract 500 pages of data within 48 hours that would’ve taken my team weeks to do. The concierge service was responsive and helpful. It was affordable.
I struggled a lot with DataMiner and still can’t manage using it. Grepsr literally saved me. It’s simply intuitive and easy to use. I had one page where data was not taken properly. After submitting information on support they fixed that in one day. Such an amazing result even keeping in mind that I am not a paid customer. Thanks a lot!
We routinely conduct detailed and sometimes obscure internet searches and crawls to support our top-end research studies. I have rarely come across a more responsive and professional organization. Grepsr does exactly what they say, faster than promised, and at excellent prices.
