Pulling Data from the Web: How to Get Data from a Website

The value of web data is increasing in every industry from retail competitive price monitoring to alternative data for investment research. Getting that data from a website is vital to the success of your business. As the trusted research firm, Gartner, stated in their blog:
“Your company’s biggest database isn’t your transaction, CRM, ERP or other internal database. Rather it’s the Web itself…Treat the Internet itself as your organization’s largest data source. ”
In fact, the internet is the largest source of business data on earth and it’s growing by the minute. The infograph below from Domo shows how much web data is created every minute from just a few websites out of a billion.

Here are a few examples:

Now that you have some examples of what companies are doing with web data, below are the steps that will show you how to pull data from a website.
Steps to get data from a website
Websites are built for human consumption, not machine. So it’s not always easy to get web data into a spreadsheet for analysis or machine learning. Copying and pasting information from websites is time-consuming, error-prone and not feasible.
Web scraping is a way to get data from a website by sending a query to the requested page, then combing through the HTML for specific items and organizing the data. If you don’t have an engineer on hand, provides a no-coding, point and click web data extraction platform that makes it easy to get web data.
Here’s a quick tutorial on how it works:
Step 1. First, find the page where your data is located. For instance, a product page on
Step 1. First, find the page where your data is located.
Step 2. Copy and paste the URL from that page into, to create an extractor that will attempt to get the right data.
Step 2. Copy and paste the URL from that page into
Step 3. Click Go and will query the page and use machine learning to try to determine what data you want.
Step 4. Once it’s done, you can decide if the extracted data is what you need. In this case, we want to extract the images as well as the product names and prices into columns. We trained the extractor by clicking on the top three items in each column, which then outlines all items belonging to that column in green.
Step 4. Once it’s done, you can decide if the extracted data is what you need.
Step 5. then populates the rest of the column for the product names and prices.
Step 6. Next, click on Extract data from website.
Step 7. has detected that the product listing data spans more than one page, so you can add as many pages as needed to ensure that you get every product in this category into your spreadsheet.
Step 8. Now, you can download the images, product names, and prices.
Step 9. First, download the product name and price into an Excel spreadsheet.
Step 10. Next, download the images as files to use to populate your own website or marketplace.
What else can you do with web scraping?
This is a very simple look at getting a basic list page of data into a spreadsheet and the images into a Zip folder of image files.
There’s much more you can do, such as:
Link this listing page to data contained on the detail pages for each product.
Schedule a change report to run daily to track when prices change or items are removed or added to the category.
Compare product prices on Amazon to other online retailers, such as Walmart, Target, etc.
Visualize the data in charts and graphs using Insights.
Feed this data into your internal processes or analysis tools via the APIs.

Don’t get frustrated when you come across such websites that your scraper fails to read for the second time. There are many reasons.

You may have seen scraper ads saying how speedy their crawlers are. It does sound good as they tell you they can collect data in seconds.

API is like a channel to send your data request to a web server and get desired data. API will return the data in JSON format over the HTTP protocol. For example, Facebook API, Twitter API, and Instagram API. However, it doesn’t mean you can get any data you ask for. Web scraping can visualize the process as it allows you to interact with the websites. Octoparse has web scraping templates. It is even more convenient for non-tech professionals to extract data by filling out the parameters with keywords/URLs.
9. The scraped data only works for our business after being cleaned and analyzed

Students can also leverage a Google scholar web scraping template to conduct paper research. Realtors are able to conduct housing research and predict the housing market.
