4.8Everything You Need To Know About Web Scraping
Everyone’s on the web scraping train these days. Businesses seek to scale digital marketing efforts and be at the forefront of SEO. Individuals see it as a relatively easy side hustle that requires only a computer, some patience, and, obviously, brainpower. Stick around and you’ll find out what web scraping is, why it’s essential, and how to do it right.
So what’s web scraping, exactly?
Data or web scraping is an automated process of gathering publicly accessible data for marketing, e-commerce, and research purposes.
Peeps scrape the web for a variety of reasons but, in the end, it’s all about using automation for business. Web scraping is attracting many favorable vibes from SMBs and freelancers who seek to make some money faster.
The whole process of scraping the web is meant for people who like to work smart, not hard.
How does web scraping work?
- It all starts with a script for your project. No matter which tool or scraper you wish to employ.
- Once the script is done, your scraper is ready to scan your target website and select the relevant information. In this case, selecting equals collecting data.
- When all the needed data has been collected, the scraper will parse it and then export it in one of your chosen formats (e.g. JSON, CSV, or XLSX).
Three things to keep in mind before scraping the web
No 1 – Use rotating residential proxies
Proxies are just as important as a scraper. We recommend scraping with rotating residential proxies because each residential IP is a real mobile or desktop device that pinpoints a certain physical location.
To any website, traffic from residential proxies looks like a request from an ordinary person residing in any corner of the globe. This way, you can avoid IP bans and flagging, solve CAPTCHAs, etc.
No 2 – Mind your browser fingerprinting
While proxies do wonders for hiding your IP address, they can’t mask browser fingerprinting. It’s a technique that identifies internet users by gathering information about their devices and operating system. This includes the type of your browser and device, language settings, screen resolution, and the like.
Although you can’t really stop browser fingerprinting, you can spoof your browser attributes, thus elevating privacy. (Note that an anti-detect browser can also give you unique fingerprints but, surely, you won’t be able to scrape the web with such a browser.)
Last but not least, try blocking Flash and/or Javascript.
No 3 – Respect the site policy
There are many different tools and softwares for web scraping. No matter how advanced your coding skills are (or even if they’re non-existent), there’s a tool for you. And if you’d rather avoid the hassle, you can hire a data broker to do the job for you (yep, it’s a real career).
In essence, web scraping is just the collection of public data. What happens with that data later is a whole different story, and it’s not all sunshines and rainbows. Some collect data for wrongful purposes such as email spam. That’s how those “I’m a Nigerian prince and I want to give you money” emails end up in your inbox…
For lawful and successful web scraping, we recommend:
- Reading the Terms & Conditions of your target websites.
- Referring to the robots.txt files of your targets (these tell crawlers which pages or files a crawler can or can’t request from a site).
What is web scraping used for?
Review and sentiment analysis
Keep an eye on what your competitors are good and bad (!) at so that you could improve your services accordingly. Besides, it’s a great way to find out what your customers’ needs are.
Email lead generation
Old-fashioned for some, the best for others. Whichever side you take, reaching new audiences via email marketing (by sending bulk emails) is still alive. Heads up, though! Email lead generation may be perceived as either tasteful advertising or annoying spam.
Competitor site check
Sneak a peek at your competitors to figure out how they market their products and what seems to be working for them and what’s not.
Real-time price comparison
Web scraping will let you compare literally anything from product pricing on Amazon to flight fares on airline sites.
Social media management
Scraping social sites will let you see what’s trending so appropriate, effective, and the best performing content could be produced. But that’s not all! For example, recruiters scrape LinkedIn to dig out more facts about potential employees.
Gathering stats
Most research companies scrape government websites and other big data sites to get statistics. Note though that we block some.gov sites.
SEO improvements
Web scraping comes in handy when tracking your website’s position on Google or another search engine. Scrape the web to watch your website go up in ranks or react to drops promptly.
And let us just remind you that SERP scraping also means gathering priceless info about your competitors to see the dos and don’ts of multiple players in your niche.
Friendly advice: you may wanna crawl using Screaming Frog, an SEO tool that performs site audits, looks for broken URLs and links, and helps with technical and onsite SEO.

Not should, but you must! Proxies are as important as a scraper. We recommend rotating residential proxies because each residential IP is a real mobile or desktop device. So, to any website, traffic from residential proxies looks like a request from an ordinary person. That’s why a constant supply of IP addresses that belong to real devices is a must.
