Effective Web Scraping Tips
Tip 1: Use the right tools
The First and most important step in the beginner web scraping projects for the people is to decide on the right set of tools for the entire procedure.
The first step of any web scraping project is to determine what kind of tools you want to use in the web scraping process. You can either build your own web scraper or purchase a web scraping service. Both come with their own advantages. If you have a tech team capable of building a scraper, you will have more control and say over what you want. However, if you do not have the skillset or your team doesn’t, it’s just as good hiring a company to do it for you so all you have to do is focus on the data.
The other tool you need is a proxy. In order to allow your web scraper to be protected, using a proxy will help protect you from any sites specifically looking for non-human activity. When that activity is detected, the IP is blocked, essentially blocking you from scraping that website.
Tip 2: Act like a human
It’s important to make sure that your activity looks like you are a human user and not a bot. Websites that look for scraping behavior will be able to detect any suspicious behavior and you will get your IPs banned.
Take your time and be intentional about the activity on any websites you’re scraping so you are able to quickly get the data that you need.
Tip 3: Respecting rules
For every website you tend to open for web scraping, you will see a list of guidelines from the website owner to the viewers in a robot.txt file. This file will inform you exactly what you can and cannot scrape on their website.
With ethical web scraping, you need to be sure to be scraping according to the rules the website has set. They are easy to find and important to follow.
Tip 4: Public data only
When web scraping, make sure that you are accessing public data only. Any data outside of that is considered unethical and give web scraping a bad name. Don’t do it!
Tip 5: Use proxies
There are different types of proxies to consider when scraping for data: residential, ISP, and data center.
Residential proxies are associated with a home or business address giving them the most authority. These will also be the hardest to detect since they are coming straight from a user’s home. While pricier, these are less likely to be banned which can come in handy when web scraping.
ISP proxies are a combination of data center and residential proxies. Housed in data centers, they have the speed but they also are assigned to ISPs (internet service providers) giving them residential level authority. Another great option in many different scraping cases.
Data center proxies are housed in data centers and known for their fast speeds. These are another great option for web scraping in specific situations. These are also the most likely to be banned as it is clear the IP is coming from a data center. Be careful when using data center for your web scraping project and that it would be a good fit for your use case.
Web scraping is a great practice for individuals, businesses, academics, pretty much anyone looking to gather information. It helps you gather the data you need and make smart, data-based decisions. It’s also important to understand best practices for web scraping in order to be successful.
