“What does it cost?” always comes first. It is also the question nobody can answer without detail.
The word scraping covers a one-off extraction of three hundred records as readily as a daily feed of several million rows. Nothing comparable between the two. Here is what moves the number, in order of weight.
The number of sources
First factor, by a distance. Collecting one site takes one extractor. Collecting ten takes ten, each with its own structure, traps and maintenance.
Going from a thousand rows to a hundred thousand mostly changes run time. Going from one site to ten multiplies the work by ten.
Once, or every day
A one-off extraction is designed, run, delivered. End of story.
A daily collection lives. It runs, it breaks, it gets repaired. That is a service rather than a deliverable, and it is the line budgets underestimate most often.
The target site's defences
A page served as HTML can be read directly. A site that builds everything in JavaScript, shows a captcha or watches for automated behaviour needs driven browsers, proxies, challenge solving. Same data at the end, nothing alike about the route.
The shape of the delivery
A file dropped once commits you to nothing afterwards. A maintained API, with uptime to hold, commits you daily. We cover the four possible formats in a dedicated article.
The quality expected
It appears on no quote and is always paid. Deduplicating, normalising addresses, recovering missing fields, handling edge cases: that is what separates usable data from a pile to reprocess.
Four answers are enough for us to give you a number. Which sites, which fields, how often, in what form. Our pricing gives the orders of magnitude.
