What is web scraping?
Web scraping aka. web extraction or web crawling refers to the process of obtaining various unstructured information from any websites and turn it into structured, clean data such as xls, csv, or txt or populate the captured data to a database directly. Some common uses of web scraping include lead generation, data collection for academic researches, price monitoring from competitors’ websites, product catalogue scraping and many more. For all kinds of good reasons people turn to web scraping and can get pretty confused about which is the best path to go.

What are some web scraping options?
When it comes to web scraping, there are two major kinds of providers available in the market, scraping tool provider and scraping service provider. Product provider basically refers to the many so called web scrapers or web extractors, examples are import.io, Octoparse, Scrapy and others. Some of these products are easier to handle for non-technical users such as Octoparse and Import.io. Some require more programming background such as Scrapy and Content Grabber. For those running on a service model, they are commonly known as DaaS, short for Data as Service. These companies do all the scraping work themselves and will provide the data to you in any formats you like in any frequencies; they will even provide weekly/monthly data feeds to you via API if needed. A few well known ones are Scrapinghub, Datahen and Data Hero etc. Among these there are also companies that provides scraping tool and provide scraping service at the same time, Mozenda scraping service and Octoparse Scraping Service. Just because they offer self-customizable scraper doesn’t mean their scraping service is any less proficient than those only do scraping service. In fact, data service provided by crawler companies can be a lot more cost efficient and are much more friendly to one-time scrapes because obviously they have the edge in owning a customizable scraping tool and only minimum manual intervention will be required.
So what it the essential difference between using a DIY web scraper and seeking help from a web scraping company? While there are many the most critical ones are,
- Willingness to learn
- Complexity of the scraping project
If you are a student looking to scrape some public data to support your thesis research with a tight budget, a scraping tool will be the best way to go; If you are an enterprises looking to outsource a brand monitoring project running on a tight schedule, data scraping service will provide you with what you need. While these are only two obvious examples of how people of different groups will find themselves at more advantages using one product/service over another, they should give you a general feeling of how to approach this question by going through your specific demands, budget, schedule, project complexity and etc.
