Avoiding Parsing Errors When Web Scraping

Web Scraping, Scraping Data From the Internet

Web scraping itself is an umbrella term for a collection of methods used to assimilate information from the internet. An integral part of web scraping is the use of data parsing. In simple terms, this is the technique used to transform data in one format to another. This is an essential step in web scraping, as different sites hold different kinds of data. Bringing it all together requires data parsing. This technique, however, can be prone to parsing errors.

What are parsing errors?

Such an error occurs when an invalid syntax is detected by the interpreter. They prevent your code from being executed. In the case of web scraping, data parsing becomes impossible. You can learn more about parsing errors and how to resolve them here.

The software involved in this data collection is designed to simulate user behaviours. This mimicking behaviour allows a large amount of data to be gathered from a variety of sources in a relatively short period of time. Web scraping can be done manually too, but automated tools eliminate a lot of the time and labour that goes into the process. This is why web scraping tools rely on data parsing techniques that take vast amounts of data and make it readable and ready for analysis.

Web scraping has a lot of uses in the business world. Whatever kind of business you’re involved in, web scraping techniques can offer an insightful opportunity for efficiency and business security. Understanding what web scraping does can help you figure out how it can benefit your business.

Web scraping and business management

The internet, as a source of information, is unparalleled. There is all kinds of data simply free floating on the interweb, and having access to this information can play a significant role in business intelligence. Keep in mind web scraping is not a technique you can use with every website. Many sites block such techniques from retrieving information, and often for good reason. Some information is private and sensitive, open access to which would be a breach. Web scraping can also use up the server’s bandwidth, causing a site to slow down or even crash.

There is virtually no limit on the kind of information you can collect through scraping tools. Depending on what you are looking for, the code designed for scraping will provide you with that information. The only exception, of course, exists for information hosted on sites that block scraping. Other than that, you can collect any kind of information, from audio, video and text data, to customer information stored on websites.

One of the most significant uses for web scraping is market research. With the kind and extent of information you gain access to, it is a time and cost-efficient method of understanding your target market and obtaining information on your competitors. In essence, it is a relatively cheap way to conduct mass research into consumer spending patterns. You can stay informed and up-to-date on consumer needs, response to products, and feedback. It can even help you identify other businesses that complement your own for merger or joint promotion opportunities.

The nature of web scraping might make it seem like a bad idea, but this technique is perfectly legal. For new startups and small businesses, it is especially a useful tool to gain a competitive edge and to help build up the business.

How web scraping benefits your business

There are a variety of uses for web scraping techniques. What you can use them for depends on the information that you use them to collect. Scraping is a good way to stay informed of trends and feedback, and you can do so in real time. Staying informed is the first step to making decisions that are beneficial to your business.

You can collect information that shows you what the best way to market your business and products is, and what consumers respond to most. An online presence is especially essential in the growing world of ecommerce, and scraping techniques can help you manage your presence. You’ll know what consumers are responding to, what isn’t being well-received, and you can even spot fake, fraudulent claims faster.

There are a lot of aspects to running a business, and believe it or not, data scraping can help you stay abreast of all of them. You can collect information to determine what the right price for your product is, that offers profits without driving away customers, how your business is doing across various distribution channels, and how your product line is doing. Essentially, any business function that requires large amounts of information for decision making is made simple with scraping and parsing.

How to scrape data from the internet

Web scraping is not a particularly difficult technique to initiate. Especially with automated tools available online, it can be a pretty straightforward implementation. If you have a tech department to handle the technical aspect, you’re good to go. If not, you can still find a viable tool and learn the necessary coding from online resources. Steer clear of parsing errors and you will be fine.

You also have the option of outsourcing this particular task. The nature of web scraping can be a potential security risk, so make sure you render the services of a reputable firm that can be relied on. That said, scraping is a useful tool, especially where business management is concerned, and if used right, can result in major returns.
