News Scraping: Everything You Need to Know

Hey there! News scraping is one of the most useful techniques that has totally changed how companies leverage online news data. In this comprehensive guide, we‘ll explore everything about news scraping – from what it is to how you can scrape news articles using Python.

Let‘s get started!

What is News Scraping and Why Should You Care?

News scraping refers to programmatically extracting data from online news sources like CNN, New York Times, BBC, etc. This usually involves writing scripts to download articles and then parse the HTML to extract information like headlines, text, authors, dates – you name it!

But why go through the effort of building scrapers? What can you do with all this scraped news data?

Plenty! Here are some of the most common and valuable uses of news scraping:

  • Reputation Monitoring – Analyze coverage of your brand across every online news source. Early detection of PR issues is critical. One retail company scrapes 50K articles a day to monitor their reputation.
  • Competitive Intelligence – Keep real-time tabs on competitors by scraping news of their product launches, executive changes, financial performance, and more.
  • Trend Identification – Discover the latest trends in your industry by mining news data for patterns. Finance firms scrape economic indicators to detect macro trends early.
  • Idea Mining – Uncover innovative business ideas and partnerships by broad scanning news content. Scraped news alerts seeded Slack‘s pivot to a messaging app.
  • SEO Optimization – Incorporate scraped news keywords into content and metadata to boost search visibility.

According to analysts, the global web scraping market size was valued at USD 2.3 billion in 2021. With so many business benefits, it‘s no wonder news scraping adoption is exploding!

This is a common question! The short answer is yes, in most cases news scraping is perfectly legal.

Specifically, scraping public factual data like headlines, dates, and article summaries is fine as long as you:

  • Avoid bypassing any paywalls or site restrictions
  • Don‘t republish full copyrighted article text
  • Comply with a website‘s terms of service

Of course, consult an attorney about your specific use case and location. But generally news scraping falls under fair use exemptions for analyzing and extracting factual data.

For responsible news scraping, simply stick to harvesting public data – not stealing content!

Scraping CNN Headlines in 5 Lines of Python

One of the best parts of Python is how quick and easy it is to write scrapers. Let‘s walk through a simple example together.

First we‘ll import Requests and BeautifulSoup:

import requests
from bs4 import BeautifulSoup

Now we can use Requests to download CNN‘s homepage:

response = requests.get(‘‘)
html = response.text

Next we‘ll parse the HTML with BeautifulSoup:

soup = BeautifulSoup(html, ‘html.parser‘)

Then extract headlines using a CSS selector:

headlines =‘.cd__headline-text‘)

And finally print them out!

for h in headlines:

In just 5 lines we were able to grab all the headlines! The .select() method makes querying elements super easy.

Now let‘s look at some more scrapers…

Comparing Python Scraping Frameworks

While Requests and BeautifulSoup offer a simple scraping solution, you may want to use more robust frameworks for larger projects. Here are some top options with key strengths:

Newspaper3kSimple API, built-in article extraction
ScrapyHigh performance, easy to scale
seleniumJavascript support, mimics browsers
feedparserEfficient handling of RSS/Atom feeds

I recommend Newspaper3k for quick scrapers that don‘t require advanced functionality. Scrapy is great for larger production scrapers that need to maximize performance.

Let‘s compare Newspapers and Scrapy scraping Hacker News:

# Newspapers
from newspaper import Article

article = Article(‘‘) 

# Prints "Hacker News"
# Scrapy 
import scrapy

class HackerNewsSpider(scrapy.Spider):

  name = ‘hn‘
  start_urls = [‘‘]

  def parse(self, response):
    yield {
      ‘title‘: response.css(‘title::text‘).get()

While both get the job done, Scrapy provides more flexibility for larger scraping projects. But Newspaper offers a quick one-line solution for basic scraping!

Tips for Scraping News Efficiently

Here are some key tips for scraping news sites efficiently and overcoming common challenges:

  • Use a scheduler – Only scrape a site every 60-90 minutes to avoid aggressive scraping patterns.
  • Handle pagination – Detect and follow pagination or "Next Page" links to scrape all content.
  • Retry on failures – Use exponential backoff to retry failed requests and gracefully handle flaky sites.
  • Distribute requests – Spread load across multiple proxies/IPs and throttle request rate to avoid blocks.
  • Cache responses – Hash and store already scraped content in Redis to avoid duplicate work.
  • Maintain user agents – Rotate a pool of randomized browser user agents to mimic organic traffic.
  • Monitor scrapers – Use Sentry or logging to monitor scrapers in production and catch errors quickly.

Following web scraping best practices like these will ensure your news scrapers stay fast, reliable and resistant to blocks.
