What is Web Scraping?

Web scraping is the process of extracting useful data from websites. The data can then be exported in a format that will be helpful to you.

Although you can copy content from a website and then paste it into a document on your computer, you would lose a lot of important data this way.

It would also take you a long time to copy everything from a website, not to mention the websites that don’t let users copy their content. 

So, how does web scraping work? Simply put, there are tools and software that can scrape data off the web for you.

Some of these software are available for free, while the rest are paid.

Before you decide to pay for software, it is important to make sure that it is simple enough for you to work with.

There are different types of tools available for web scraping, and not all of them will be useful for you. 

Overview of Open Source Web Scrapers

Open-Source Web Scrapers

When choosing a web scraper, you should not only consider the data that you wish to extract but the amount of control you want.

Although most scrapers let users select the data they wish to extract, they still might not have all the features you want, or they may not work with the kind of content you want to copy.

The best way to avoid that is to choose open-source web scrapers. 

Open-source software can be inspected and modified by anyone. The copyright holders give people the right to change the source code of their software for any purpose.

So, if you want complete control over the scraping processes, you should work with an open-source web scraper.

If you use an open-source web scraper, you can easily scrape in a fast and extensive way.

If you have sufficient programming knowledge, then there’s no reason for you to choose anything but an open-source web scraper. 

What Are the Uses of Web Scraping?

You may wonder what’s the point of web scraping when you can visit different websites to access the information you want.

But if you have ever turned to a website that compares the prices of different products, then you have already benefited from web scraping. 

Industry-specific Insights

A company can get help from a scraper to extract extensive data and then analyze it to draw industry-specific insights.

Companies can sell this data to other companies in the relevant industry.

This data is quite valuable as it can inform companies of various trends in the industry and help them make fruitful decisions. 

Real Estate Listings

You can see multiple listings on the website of a real estate agent. These listings are often scraped off MLS listings.

These listings are scraped off to build an API so the data can be sent to the website of the real estate agent or agency.

If someone finds the listing on a real estate agent’s website, they can act as the agent and earn a commission once the deal is sealed. 

Price Comparisons

Whether you are thinking of buying a mobile phone or a home appliance, you would choose multiple options, compare their prices, and then make a decision.

There are different websites you can turn to compare the prices of various products. These websites are often set up with the help of a web scraper. 

Prices of different products are scraped off Amazon and other online stores and added to the website for comparison.

Multiple web scrapers are specifically designed for extracting information about prices from different websites. 

Lead Generation

Digital marketing is all the rage these days, but if companies don’t have the contact information of potential customers, there isn’t much they can do.

Fortunately, web scraping can help companies with lead generation by extracting the contact information of potential customers from various websites.  

If a company has the contact details of potential customers, it can easily reach out to them about offers and discounts.

Turning potential customers into regular customers can become possible this way. Web scraping is also helpful in the business-to-business space.

Customers in this space post their contact details openly so extracting information about them won’t be difficult. 

Social Media Analysis

Things change pretty quickly on social media websites. If you are too late to join a trend, it might already be over.

Businesses can lose the opportunity to act on the latest trends and attract new customers.

But with web scrapers, you can easily extract data from multiple social media websites. 

The analysis of social media posts is not only important for businesses but also for politicians and policymakers.

The analysis can show the decision-makers how people are reacting to different things and what is their opinion on policy matters. 

Investment Options

If you are looking to invest in real estate, you can make use of a scraping tool to find out about promising neighborhoods.

You can focus on keywords like highest-rated houses and attractive renting locations.

Real estate agents use the scraping tool to learn about good neighborhoods and make investments in property accordingly to make money. 

Is Web Scraping Illegal?

The biggest concern people have about web scraping is whether it is legal or not. The answer to this question depends on the kind of data you are scraping off a website.

For instance, if you are extracting data that is not publicly available, scraping becomes illegal. Local laws might also play a role in deciding the legality of web scraping. 

The Features of a Good Web Scraper

There are various factors that can help you figure out which open-source web scraper to go for.

But the most important thing to keep in mind is the programming language the scraper runs on.

Even if you are familiar with both Java and Python, it is better to go for the one you have worked with for longer. 

The second thing to consider is the interface and ease of use. Even the best feature would be useless if you can’t figure out how to use it.

If a web scraper is easy to use and also comes with detailed documentation on how to run it, then you should definitely give it a try. 

A good web scraper must also be reliable and quick. You don’t want it to stop halfway through a scrape and waste your time.

It is also important for a good scraper to offer multiple output formats so the users can get data in the format of their choice. 

Final Thoughts

A web scraper can be a great way of extracting the information you need from web pages.

But in order to make your scraping experience worthwhile, you must choose the right web scraper.

All the open source web scraping tools mentioned above have been tried and tested by multiple developers.

So, if you need to scrape data off the web, try one of the web scrapers mentioned above and see which one best suits your requirements.
