Let‘s dive in to unlocking the trove of opportunities hidden in Bing‘s billions of searches.
The Tantalizing Promise and Legal Risks of Scraping Bing
First, we must address the obvious question – can you legally scrape Bing search results?
The short answer is it‘s complicated. Broadly speaking, US law and jurisprudence around web scraping remains unclear. There is no definitive federal statute that explicitly prohibits or allows scraping.
Relevant laws like the CFAA (Computer Fraud and Abuse Act) and DMCA (Digital Millennium Copyright Act) may apply circumstantially depending on how scraping occurs and the purpose. Most cases around scraping have relied on these statutes.
For example, in the closely watched LinkedIn vs. HiQ case, HiQ scraped public LinkedIn user profiles for business intelligence services. LinkedIn alleged violations of the CFAA and DMCA, but HiQ prevailed on appeal with scraping protected under fair use.
However, other cases like Sandvig vs. Barr saw the DOJ argue that all scraping, even of public data, inherently exceeds "authorized access" under the CFAA. This creates risk of criminal penalties. The implications of both rulings are still evolving through new cases.
What Bing‘s Terms of Service Permit
Beyond these federal laws, site terms of service also govern scraping jurisprudence. Microsoft‘s Terms of Use for Bing prohibit a few specific activities:
- Launching denial of service attacks
- Disabling or compromising the integrity of Microsoft‘s products
- Attempting to gain unauthorized access to Microsoft‘s systems or data
Broad crawling or scraping does not seem to be explicitly prohibited based on my interpretation. However, the Terms do reserve Microsoft‘s right to:
"limit your use of the services to prevent harm to other Users, us or third parties."
This provides Microsoft latitude to restrict scraping if they deem it excessive or intrusive.
Treading Carefully to Avoid Legal Risks
Given the complex legality, scraping Bing requires treading carefully. Here are some tips:
- Consult an attorney – Get advice tailored to your specific situation and jurisdiction on potential risks.
- Review terms frequently – Check Bing‘s Terms often for changes that may impact scraping.
- Scrape ethically – Avoid denial of service and excessive loads that may trigger limits.
- Use data legally – Don‘t sell or misuse scraped data in ways that violate rights.
- Mask scraping activity – Make scraping appear more human-like and less intrusive.
While the law remains unsettled, responsible scraping for legitimate business intelligence purposes seems permissible currently based on my understanding. But legal guidance is still highly recommended.
Next, let‘s examine some key technical challenges Bing presents for scrapers.
Why Scraping Bing is Challenging
If harvesting search data from Bing was straightforward, everyone would be doing it already. Here are some key obstacles in the way:
Bot Detection and IP Blocking
Like most prominent sites, Bing employs advanced bot detection systems to identify patterns of automated scraping activity. Scraping from a single IP will often get blocked in minutes to hours.
Bing‘s systems analyze many signals – request frequency, headers, interactions, clicks etc. Once flagged as a bot, your IP can be permanently blocked.
Heavy Reliance on JavaScript Rendering
Modern sites like Bing dynamically generate their user interface and content using JavaScript executing in the browser. The raw HTML from a requests call won‘t contain the data we need.
JavaScript must be executed to fully construct the search results page. This complexity makes parsing the finished DOM challenging.
Shifting Page Structures and Parameters
The URLs, page structures, and query parameters on Bing are constantly changing rather than a fixed template. This requires continuously updated parser logic.
For example, pagination uses POST requests and relative page numbers rather than a simple &page=2 pattern. The location of result elements may also shift.
Evolving Evasion Tactics
Search engines are in an arms race to detect ever more subtle signs of scrapers. Tactics like mouse movements, scrolling, and clicks help avoid patterns.
Bing may deploy other advanced tactics like page randomization, silent blacklist banning, or honeypots/traps for scrapers.
The Stakes are High for Getting Banned
A single mistake that gets an IP address flagged as a scraper could lead to a permanent ban from Bing. This makes operating safely with minimal footprints crucial.
Losing access to a major search engine could cripple SEO monitoring, reporting, and competitive intelligence.
Thankfully, with the right approach and tools, these hurdles can be overcome to access Bing data at scale. Let‘s explore the key ingredients next.
Scraping Stack: Python Libraries for Extracting Bing Results
Sophisticated bots can be challenging, but thankfully Python offers a robust set of libraries purpose-built for automation.
Here are the key modules we‘ll leverage:
Requests – Simplified HTTP Requests
The Requests library provides an elegant API for creating HTTP requests in Python without low-level complexity. We can use it to easily request Bing result pages.
BeautifulSoup – DOM Parsing Made Simple
BeautifulSoup is a battle-tested Python library for parsing and extracting information from HTML and XML documents. We can use it to analyze the Bing results pages and extract the data we need.
Selenium – Browser Automation and JavaScript Execution
Selenium allows controlling an actual browser like Chrome directly from Python code. This will allow our scraper to load JavaScript and render fully-populated search results.
pandas – Powerful Data Analysis Toolkit
The pandas library provides highly optimized tools for cleaning, transforming, and analyzing structured data in Python. We can leverage it to wrangle and store extracted search data.
proxies – Masking Scrapers with IP Rotation
Residential proxy services like Luminati allow routing requests through thousands of IPs. This masks scrapers and protects against blocks. Integrating proxies is essential for large-scale Bing scraping.
With these powerful libraries, we have all the ingredients necessary to build a robust Bing scraper. Now let‘s examine how to put them together.
Assembling the Bing Scraper Step-by-Step
Let‘s walk through a proven process for extracting data from Bing at scale:
1. Configure Selenium with Browser and Proxies
First, we‘ll configure a Selenium webdriver instance with Chrome as the target browser.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
webdriver = webdriver.Chrome(options=chrome_options)The headless flag runs Chrome in invisible mode for undetected scraping.
Next, we integrate proxies by defining the --proxy-server argument with IPs supplied from our proxy service:
proxied_options = chrome_options
proxy = random_proxy() # Fetch new proxy IP
proxied_options.add_argument(‘--proxy-server=%s‘ % proxy)
proxied_webdriver = webdriver.Chrome(options=proxied_options)This routes the scraper through proxy IPs to mask its activity.
2. Construct Target Search URL
Now we can build the target URL to extract data from. Bing‘s base search URL is:
https://www.bing.com/search?q=We simply append our query keywords to this:
search_term = "web scraping"
search_url = "https://www.bing.com/search?q=" + search_term This assembles the Bing search URL for our chosen term.
3. Load Search Results Page
With the target URL assembled, we use Selenium to access the page and load the fully rendered HTML:
proxied_webdriver.get(search_url)
page_html = proxied_webdriver.page_sourceBy using Selenium through a proxy IP, we fetch the complete search results protected from bot detection.
4. Parse Results with BeautifulSoup
Now we can parse the result HTML using BeautifulSoup to extract the data points we want:
from bs4 import BeautifulSoup
soup = BeautifulSoup(page_html, ‘html.parser‘)
titles = soup.find_all(‘h2‘)
links = soup.find_all(‘a‘)
snippets = soup.find_all(‘p‘)BeautifulSoup conveniently locates and extracts result titles, links, snippets, and more.
5. Store in pandas DataFrame
As we extract data, we‘ll store it in a pandas DataFrame for analysis:
import pandas as pd
df = pd.DataFrame()
df[‘Title‘] = titles
df[‘Link‘] = links
df[‘Snippet‘] = snippetsWe now have our results accessible for data cleaning, analysis, and export.
6. Iterate Through Pages
To move through multi-page SERPs, we increment a page counter to update the URL parameter:
page = 0
max_pages = 10
while page < max_pages:
# Update search URL
search_url = base + "&first=" + str(page*10)
# Load > parse > extract
page += 1This allows iterating through and aggregating data across many pages.
7. Export Data
Finally, we can export the scraped dataset using pandas for offline analysis:
df.to_csv("bing_results.csv", index=False)
df.to_json("bing_results.json", orient="records")This provides easy access to the extracted data as CSV and JSON files for further mining.
This covers a battle-tested process for building a robust Bing scraping solution leveraging Python. Next let‘s explore what‘s possible by tapping into this data.
