Why has web scraping become so valuable?
Before diving into specific use cases, it‘s helpful to understand why web scraping has moved from a niche technical tool to a mainstream business solution.
Web scraping allows accessing data at scale. The internet contains endless sources of valuable data – from product listings to social media chatter. Manually extracting this information is time-consuming and inefficient. Web scrapers can automatically gather thousands of data points in minutes.
It enables informed, data-driven decisions. All businesses want to make strategic choices based on actionable insights. Web scraping provides the raw data needed for analytics on everything from prices to customer sentiment.
It creates opportunities for new business models. Web scraping isn‘t just used for internal purposes – some companies are built entirely around data gathered through scraping. Review sites, price comparison engines, and market research firms all leverage scalable data collection.
It saves time by automating manual work. Repeatedly visiting websites to copy data is tedious for staff. Intelligent scraping bots handle these mundane tasks, freeing up employees for higher-value work.
It helps monitor outside forces impacting a business. Competitor prices, brand reputation, investor chatter – web scraping provides visibility into external factors, allowing companies to react appropriately.
Now let‘s explore some of the most popular and emerging uses of web scrapers across industries:
Core Business Applications
Continuous price monitoring
One of the most common uses of web scraping is to monitor competitor pricing from e-commerce sites. By scraping sites daily, businesses can adjust their own prices to stay competitive. Dynamic pricing algorithms often incorporate scraped data on rivals‘ prices.
Scraping also enables enforcing pricing policies like minimum advertised price (MAP) by detecting violations and unauthorized discounts. The major camera manufacturer Canon uses web scraping to monitor reseller prices across thousands of listings and identify MAP violators. They‘ve substantially reduced unauthorized discounting through their scrapers.
Aggregating data from multiple sources
While a single website may hold useful data, combining relevant information from hundreds of sources can provide even more powerful insights. Web scraping is ideal for aggregating heterogeneous data sets.
For example, metasearch travel sites like Kayak scrape listings from major OTAs, airlines, and hotels to give users comprehensive pricing options in one place. By aggregating disparate data, they deliver a service that wouldn‘t be possible otherwise.
Generating leads
Contact information, demographics, interests – public websites and social networks hold vast troves of data that can be mined to generate new sales and recruiting leads.
Data service providers like ZoomInfo and Apollo scrape the web and compile listings of company contacts and professional profiles – a valuable prospecting resource. LinkedIn Recruiter and other HR tools also use lead generation techniques.
According to Forrester Research, over $4.6 billion was spent on B2B lead generation in 2022 alone. Web scraping is now a key enabler behind the lead gen industry.
Monitoring brand reputation
Understanding how a company‘s brand is perceived online has become critical. Web scraping software can track mentions across the web – on social networks, review sites, forums, and blogs – to provide insights into brand reputation and help address negative publicity or rumors before they spread.
Brand monitoring is also used to catch illegitimate use of brand assets. Scraper bots can detect copyright violations, fake social media profiles, and cybersquatting. Luxury fashion house Chanel employs web scraping as part of their anti-counterfeiting efforts.
Scraping for Competitive Intelligence
Identifying new investment opportunities
Hedge funds, venture capital firms, and traders are investing heavily in alternative data scraped from across the web in order to gain an investing edge.
Product reviews, employee sentiment ratings, cybersecurity breaches, clinical trial outcomes – these and countless other data points are being parsed by algorithms to predict stock performance and identify promising investments.
J.P. Morgan Asset Management told Bloomberg they incorporate scraped data from over 1,000 alternative sources into their quantitative investment strategies.
Monitoring SEO performance
Search engine optimization has become heavily data-driven. Web scraping helps SEOs research competitors, track keyword rankings over time, perform site audits, and discover new link-building opportunities.
Scraping tools like Moz and Ahrefs have been adopted by SEO agencies to automate competitive research and reporting. The data they provide influences strategy and recommendations.
Analyzing consumer sentiment
Product manufacturers and service providers closely monitor social media, reviews and forums to understand consumer attitudes toward their brand and offerings. Sentiment analysis based on text scraped from these sources provides valuable customer feedback.
The analytics firm Alteryx found that 90% of the largest global brands use social media scraping for monitoring and insight mining.
Emerging Use Cases
Training AI and machine learning models
Gathering high-quality training data is a fundamental need and major bottleneck for many AI systems. Web scraping can rapidly generate text, image and structured data sets on virtually any subject from online sources to use in model development and validation.
Researchers at the Indian Institute of Science created a deep learning tool called SenticNet by scraping over 50 million sentences with emotional connotations from the web as training data. The resulting sentiment analysis model is now used by major banks and financial firms.
Local SEO monitoring and outreach
With Google increasingly favoring local results, monitoring location-specific SEO data like Google Maps listings, Local Pack rankings, and reviews on neighborhood forums has become crucial.
Web scraping enables multi-location brands to audit name, address and phone (NAP) consistency across the web and listings sites. It also helps identify locally-relevant link building and outreach opportunities.
Testing and monitoring websites at scale
To deliver robust digital experiences, development teams need to continuously test sites under realistic loads. Web scraping bots can simulate user traffic for stress testing and performance monitoring.
Scraping all site pages also helps identify problems like broken links. Content teams use scrapers to audit sites and get alerts when changes occur. E-commerce sites confirm product info stays up-to-date across catalogs.
Building data sets for academic research
Academics have adopted web scraping as a research tool across disciplines from political science to epidemiology. Scraped social media data provides insights into public health trends. News and government sites offer corpus material for machine learning research.
A study by MIT researchers used millions of Yelp reviews scraped weekly to analyze trends in gentrification across U.S. cities. Open datasets fuel much of today‘s cutting-edge research.
How to Get Started with Web Scraping
Now that we‘ve covered some of the most valuable business applications, here are a few parting tips on integrating web scraping successfully:
-
Use proxies – Websites try to block scrapers, so residential proxies are essential to manage requests. Proxy rotation helps avoid IP bans.
-
Evaluate legal compliance – Assess how you‘ll scrape within platforms‘ terms of service. Some data may have usage restrictions.
-
Start with a focused use case – Implement scraping for a single well-defined need before expanding. Quick wins build internal buy-in.
-
Consider outsourcing – Managed scraping services handle infrastructure and APIs so you just get data. They offer tech expertise and legal cover.
-
Monitor performance – Track metrics like requests scraped, data volumes and failures. Tweak approaches to improve efficiency.
Web scraping enables leveraging the internet‘s treasure trove of public information for competitive advantage and intelligent automation. Adoption is soaring as companies recognize its strategic value. While extracting maximum insights takes some technical acumen, the payoff for organizations who harness web data can be game-changing.
