Web scraping, explained simply

What web scraping is, what it's concretely for, and the framework to use it in. A quick overview.

Web scraping is the automated extraction of data found on websites. Instead of copying and pasting information by hand, a program retrieves it and organises it for you.

The uses are many: tracking prices and catalogues on e-commerce sites, aggregating real-estate listings, building B2B prospect lists, or monitoring a market.

The principle is always the same: locate the useful information on the pages, extract it, then structure it into a clean format, such as a table, a database or a feed your tools can use.

Then there is the question of framework. We work with publicly accessible data, at a controlled pace so as not to disturb the sites we consult. Defining the uses is your responsibility, and we advise you on it.

Web scraping becomes valuable as soon as data exists online but no interface lets you retrieve it easily, at volume or on a regular basis. That is where Keldin comes in.
