Data Miner Crawl is for when you have a list of items on a webpage that you need to click into to see additional data. This is a two step process that uses a combination of a List Recipe and Detail Recipes .

Crawl Process Overview

This process requires two recipes. The first recipe is used on the search results page and extracts the detail page URLs from every individual item.

You will then take this list of URLs and upload it to Data Miner. Data Miner will then visit every URL and apply the second recipe, which is used to scrape the details.

Once the process complete, you will have a file with the combined data from the list page and each detail page. Continue below to see complete documentation.
