For those who are going to extract information from websites, web scraping tools will be indispensable helpers. This technique is developed for the large-scale extraction of information from websites. However, with the huge variety of scraping tools and services available, it can be difficult to choose a program just right for your needs.
To help you with your choice, this article takes a look at the different web scraping tools available and how to choose them.
What’s API in Web Scraping?
Application Programming Interface (API) is an interface that allows apps to communicate and work with each other. It is like the link between your device and whatever is delivered to it at your request. This is usually done to develop other applications that use the same data.
API is one of the most common tools for collecting data using web scraping. It helps in obtaining valuable and structured data without having to research and collect information on your own.
One example is the Ahrefs data extraction API. The site has a complex algorithm and data collection model that provides all the information about keywords, their volume, traffic to sites, and so on. Here, the scraping API makes the process of extracting information from Ahrefs quick and easy, as users can get SEO-related information collected by Ahrefs simply by typing a keyword into the search bar.
Is Web Scraping API Legal?
Application programming interfaces consist of rules that create structure, impose restrictions on users, control retrieved types of data, frequency of requests, and which sources are open for collection. An API is like an individual website or application communication protocol with specific rules to follow.
Why Use a Web Scraping API?
Easy integration. The developer can implement the web scraping API into the application using only a set of credentials and a clear understanding of the API documentation.
Time-saving. Instead of collecting information manually, the scraping API automates the whole process. You won’t have to fumble with creating, downloading, or installing it. Integration, configuration, and getting started – the API will do it all.
Cost efficiency. Choosing API isn’t the cheapest choice, but it’s not the most expensive either. Prices vary depending on how many API calls you’ll make per month and how much bandwidth you need. Nonetheless, it’s a worthwhile investment.
Speed. This talks about the way the data is extracted. The web scraping API is optimized to be fast.
The site is not overloaded with traffic. A surge in traffic can cause any site to slow down or crash for a while, which can be the result of both bot and human activity. To protect themselves, many sites implement spec algorithms to distinguish humans from bots. And since bots are responsible for web scraping, you run the risk of being blocked and losing data. So with the web scraping API, you can set the wait time before the two execution phases, limit the access rate, and avoid detection by specification algorithms.
Factors to Consider when Choosing Web Scraping Tools
There are a number of variables to consider when choosing a data scraping technology. Each person has different requirements, and there are a number of different tools for them. For example, serious data enthusiasts want tools that can do both basic and advanced tasks. Here are the factors by which a web scraping tool should be evaluated first:
Scalability. The tool you choose should be scalable, as your scraping needs will only grow over time as the demand for data increases. So you need to choose a tool that doesn’t slow down as your data needs increase.
Avoid anti-scraping mechanisms. Some sites have anti-scraping measures in place and on such sites, you cannot freely extract data. However, most of these measures can be bypassed with simple scraper modifications. A good web scraping tool can help deal with such a situation. You should make sure that the tool you buy has mechanisms to avoid anti-scraping mechanisms.
Price. Prices for the tool you choose should be transparent and every explicit feature should be clearly stated in the pricing structure.
Data quality. Most data on the web is unstructured and needs to be processed before it can be used for your purposes. Look for a tool that has the features to clean up, organize the collected information, and provide it in the format you need.
Data delivery. The choice of the tool also depends on the data format in which you would like to receive the information. Data delivery formats can be XML, JSON, CSV, or on Dropbox, Google Cloud Storage, FTP, etc. It is better to find a tool that provides data in different formats.
Customer service. If you encounter a problem while the web scraping tool is running, you may need help to resolve it. Also, the data may be corrupted or unstructured and you may have many questions to ask the experts. This is where customer support is one of the important factors in choosing a good tool. With good customer support, you won’t have to worry about the hassle of collecting data.
