People out there are looking for jobs in the Data Science field but do we really need jobs if we have the right skillset? Let's find out.
Before we go forward, it's important to understand what 'Web Scraping' means.
In simple terms, Web Scraping is the process of collecting structured web data in an automated fashion. It’s also called web data extraction.
Scraping the web can be a good source of income if you put in the time and effort. Making money off of web scraping is very possible and not as difficult as it seems. In this article, we will talk about how to scrape the web and create datasets that can be used by businesses for marketing or their personal use.
What is Scrapy and why do we need it?
Sometimes Kaggle is not enough, and you need to generate your data set.
Maybe you want to scrape the images of your favourite singer or the Data Science interview questions on Quora. Whatever your reasons, scraping the web can give you very interesting data, and help you compile datasets.
Scrapy was designed originally for web scraping. However, it can also collect data through APIs, or be used as a general web crawler. It’s the scrapers' best friend today, you just need to understand the basics of python programming or need to learn from a professional to use it well.
Who needs your services?
In a world where everyone wants to make money, Web Scraping has become a very unique and new way to make money on the side. Where if you apply it to the right situations it can make you a ton of money, and it is easier to do than most people think.
Scraped data gets used in all sorts of useful ways. Some of them are:
- Build and sell a list of leads:
Every sale starts with a lead. As a result, all kinds of businesses around the world will spend thousands of dollars on high-quality lead lists. There’s a slew of startups out there that are trying to automate lead generation and outbound sales. Data helps them track down the right people in the right companies while providing context and sometimes contact details to boot, following scraping practices for building high-quality lead lists helping you give good returns.
- Data to compete in markets:
A slew of companies uses data to track product information. Think of price comparison apps for consumers, spotting price changes by their competitors so they can adjust prices faster, monitoring that their resellers are not offering their product for a lower price than agreed, and also applying sentiment analysis across end-user forums.
- Hiring process:
HR departments and companies are more interested in profiles or the candidates they should be headhunting, to begin with. There’s a lot of information that can be collected across the web and help them decide which candidate will be a good fit for the position they’ve offered.
- Scrape data to build an app:
Why not try your hand at app development?
I know, this sounds quite intimidating. But with web scraping, you can scrape the data you need to build a simple app without the need for any coding skills.
For example, let’s say you’d want to create a simple investment app that sends you an email when a stock hits a specific price. This you can do using the Yahoo finance data.
- Uncover market opportunities:
You can use web scraping to identify market opportunities and gaps in product offerings. For example, let’s assume you’ve scraped data on all mobile phones being sold on Amazon/Flipkart. From your research, you have noticed that there’s a certain price range for which all products get low review scores. For example, mobiles priced within the 7000 to 10000 price range all average about 3 stars in review scores. They also get tons of reviews, meaning that people are buying them but are not pleased with them. This means there is a gap in the market for mid-range mobiles that can meet the customers’ expectations.
- Resolve lawsuits:
Legal departments and companies use data to gather documents for discovery or due diligence purposes. This data helps them trendsetting with legal developments in and around the industry or mining laws and jurisprudence that may be related to their legal cases.
- Government using it:
An obvious agency using data is governments. National statistics offices, for instance, are seeking to automate computing consumer price indexes. And law enforcement agencies are scraping the dark web to locate and watch criminals. To great effect, we dare add: not a month goes by without busting a human trafficking ring in India, and Scrapy helps government do that.
- Take up paid web scraping gigs:
Why not work for a web scrapper firm. Many companies often decide to outsource their web scraping jobs and can offer some pretty decent payouts for more complex jobs. Also, you can scrape LinkedIn to find your Job.
