The web scrapers industry has been functional for many years, even to the point where abusive practices have become the norm. There was a time when software developers had more of a need for data scrapers. However, now it is common to have large amounts of data being scraped and accessible through APIs. It is quite possible that this act went from an ethical thing to something less than desirable today.
I think scraping is a very important tool in the web designer’s toolkit. There are times when getting information from government websites, for example, and is not available through an API or any other convenient method. We are seeing more and more instances where scrapers are being used to bypass paywalls, which has always bothered me.
Paywalls for news sites were designed to keep people from reading their articles without paying them money. While we have a more open information culture in this day, that does not mean there should be no paywalls at all. It just means that these paywalls should be actively protected in order to prevent people from bypassing them.
While scraping can be seen as a popular practice, there are still those who wish to use it as a tool for doing the right thing. There are plenty of instances where scraping is used by independent designers and programmers who want to create new products based on their own research.
What are web scrapers?
Web scrapers are a type of software used to located and extract valuable data from websites. This can include information such as contact details, upcoming events or even news articles. Scraping is the act of extracting data from a website without prompting the owner of that website for permission. The process is pretty simple, and it involves writing code that runs along with a website and extracts the information necessary for you to get the desired data.
There are many reasons that people scrape data: Some do it for profit, while others do it for research purposes. Regardless of their cause, web scrapers have become a common practice on the internet today.
How do they work?
When using PHP or Python, you must write code to interact with the website. This makes it a bit harder for beginners and those who are working on a smaller budget.
Why use web scrapers?
For many years, web scrapers were used for good. Programmers used them to create search engines, browser-specific tools and even free online newspapers based on data they had extracted themselves from websites. Web scrapers were a way for developers to get their information from websites without needing permission and without paying the fees associated with using an API.
However, as the years have progressed, it has become common practice for scraper makers to use these scripts to defraud websites in order to get the information they don’t actually need. Web scraping is a common problem that we have been facing now for many years, and we are still stuck in this situation.
How to use the web scrapers to your advantage?
There are a few ways to use scrapers to your advantage. Probably the most common use for scrapers is in creating search engines. There are many who find these kinds of sites very helpful, and there is nothing wrong with that. As long as the search engine does not violate someone else’s copyright, there shouldn’t be any real problem with this.
You can also use scrapers to generate your database of information from various sites. There is a lot of complexity to find otherwise, and it is much easier when you can scrape this data for yourself and use it for whatever purposes you want.
Examples of website scraping and its benefits
Here are two examples of how websites scrape data:
1. Customizable weather sites
A couple of years ago, we had a problem with customized weather sites not working properly across all browsers. The problem was quite annoying, and the cause was out of our control. However, some web scrapers allow you to access weather data from various locations around the world, get information about it and put it into a personal database where you can view the data from multiple places altogether.
2. A news aggregator site
A couple of years ago, there was a big problem with paywalls on news sites. More and more people were starting to use web scrapers to get past the paywall and read all of the articles for free. This caused a lot of problems for people who did not have any money, to begin with, and it was also harmful in terms of copyright law.
Wrapping it up
While the use of web scraper tools may seem like a simple and common practice, there are still those who wish to use it as a tool for doing the right thing. There are plenty of instances where scraping is used by independent designers and programmers who want to create new products based on their own research. Luckily, it is not an illegal practice of web scraping, and you are free to use the software that makes web scraping easier for you.
However, you should be wary about using scrapers to get information for which you don’t have any reason to need. There are a lot of potential problems associated with this practice, and you should always research what kind of harm you might cause by scraping a website. You should also be aware that not all scrapers are the same, and some can cause more harm than good.
