Before embarking on a project to write your own web scrapers, here are 10 questions to ask yourself and your team:
- Does your team have the experience in writing code for web scraping? (It is harder than it looks)
- What are the server / networking / storage costs to continually run your web scrapers?
- What happens when your IP addresses get blocked by the websites that you are scraping? (It will happen)
- How will you deal with CAPTCHA and the slew of more sophisticated anti-scraping methods?
- What happens when the websites you need data from change? How quickly can you rewrite your code?
- Are you ok with gaps in your data when your web scraping fails?
- How will you deal with a “dynamic” website where the content changes but the URL stays the same?
- What happens when the website requires a login or the submission of a form before data is displayed?
- What is the opportunity cost on your business taking time away from core engineering responsibilities?
- What happens when the engineers who built your web scrapers leave?
- If you need high quality web data at scale, it will work out 20 to 30 times cheaper to partner with Import.io than to build it yourself.
