Web scraping tips
We want to make it easy for you to start web scraping, that’s why we have put together these web scraping tricks and tips that you can follow when working on your beginner web scraping projects.
Have the right tools for web scraping
Before you can start web scraping, you need to have the right tools for what you want to do. If you don’t have knowledge of any programming languages, then you might want to use an online web scraping tool. If you do have programming knowledge, or it won’t be an obstacle for you, then you can build one.
If you need more customization when web scraping, then you may need to build a web scraper. If your web scraping needs aren’t complex, then using an online tool can save you time and make this process easier for you. Before you look for a web scraping tutorial for beginners, you should know what your web scraping needs are.
You need to decide if you want to use a desktop app when web scraping or a cloud-based solution. Both options have their pros and cons and knowing them will help you decide on what option is the best choice for what you need.
A desktop app will not have restrictions like a cloud-based solution will, so if you need to extract a large amount of data, then you should not choose the hosted solution. To make the best decision, you need to understand what you need from the web scraping process.
Using proxies is important when web scraping. Anti web scraping systems will look at your IP address, and if they find you web scraping, then they will blacklist your IP address. You will then be unable to visit or scrape the data on that website. By using a proxy, you can display a different IP address as the one requesting to scrape web data.
Simulate human behavior
Web scraping slowly will help you extract the data you want from web pages and not be prevented by anti-web scraping systems. By web scraping slowly and using delays randomly during the process of web scraping, the systems will think you are a human and not a bot.
A web scraping tutorial for beginners might not tell you how important this tip is. You need to simulate human behavior to get the data that you want quickly.
Respect websites and their rules
Before you start web scraping, you need to read the robots.txt file that is written by the owner of the website. This will tell you what web pages you can scrape and which ones you cannot. This file can include other important information that the website’s owner wants you to know. This could be the frequency that they want you to web scrape at, and what you shouldn’t do.
You need to respect the website’s owner, and the people using the website. If you are scraping a large amount of data, this can slow down the website, so you should wait until the website isn’t as busy. If you don’t respect the rules of the website when web scraping, you will be blocked.
Web scraping public data
There are all types of public data that you can scrape to analyze and make better decisions with. We will talk about the popular ones and why they are used by so many people and businesses.
Price intelligence
Web scrapers are used to extract the retail prices of stores so the competition’s prices can be monitored. Retailers use web scraping for this to stay competitive, find trends the market is showing, and give their customers a better experience and service than other stores can give.
Search engine optimization (SEO)
Web scraping is used to help businesses and people improve their Search Engine Optimization. The large amounts of data that is extracted is used to find the keywords people are searching for, and what people are interested in. This information is then used by businesses to improve their online presence within search engines.
You can research your competition, find backlinks, and direct your efforts to the customers that are more likely to engage with your business and website.
Statistics and data
Businesses use web scraping to populate large databases with information they can analyze and get insights from. This helps them make the best business decisions by giving their customers what they want, and offering services that other businesses aren’t.
Generating leads
Businesses use web scraping to find people that will want to buy their products and use their services. The process of web scraping will extract the contact information of these likely customers so the business can focus its efforts on them to sell more products.
Use The Right Proxies
When web scraping, you need to use proxies. This will make your web scraping experience better and help you get the data you need faster and more easily. There are different types of proxies, such as ISP, data center, and residential proxies.
ISP Proxy
These proxies have the attributes of both data center and residential proxies. An IP address is assigned to the user by an ISP, and it’s hosted on a data center’s servers.
ISP proxies look real, so websites think you are a normal user browsing using their own IP address. This reduces the risk of being blocked by the website. These proxies are hosted on data center servers, giving you faster speeds to perform web scraping.
Data Center Proxy
These proxies have IP addresses that are owned by web hosting companies and other organizations that aren’t working with ISPs. There are private, public, and shared data center proxies.
Data center proxies have high speeds and high uptime, making them ideal for web scraping large amounts of data. You can use a static IP address for as long as you want. You can use proxies from all over the world.
Residential Proxy
These are proxies given to users by ISPs or Internet Service Providers. These proxies look like the IP addresses of normal users browsing the internet. There are static and rotating residential proxies.
Residential proxies will let you send concurrent requests to speed up your data collection when you are web scraping. Anti-web scraping systems will be less likely to block your Ip addresses if you’re using this proxy.
Conclusion
Web scraping is used by businesses and people to extract valuable data and get insights that can be used to benefit them. There are many tools that you can use, and different options to choose from when you are web scraping. You need to make the right choices to help you succeed in web scraping, and by following this article’s tips, you can do that.
