What is price scraping?

Is web scraping the same as screen scraping?

I have a lot of experience with web scraping but I am struggling with the terminology.

Are they the same thing? What is the difference between the two? Web scraping is about automating the fetching of data from websites. Web scraping may involve: Fetching data from websites, usually using a programming language. Extracting data from websites that is in a format that can be processed. Screen scraping is about extracting data from websites using a GUI program. Screen scraping may involve: Fetching data from websites, usually using a GUI. There are differences between web scraping and screen scraping, but both are automated ways of extracting data from websites. Wikipedia defines web scraping as: Web scraping is the practice of using client-side software to extract. information from a website. While it can be considered as synonymous with web extraction, it is not, as the scope of web scraping is strictly limited to web-browsing. In addition to this, it's the part where we automate fetching of information from websites. The term "screen scraping" on the other hand has broader scope. It's a process of extracting information from a computer display device (screen).

I'm surprised no one has mentioned the difference in usage between these terms. Web scraping: Web scraping is the process of automatically harvesting information from websites. Screen scraping: Screen scraping is the act of using a GUI to search for information within a computer's display. The above definitions alone, however, don't tell the whole story. Both web scraping and screen scraping are considered forms of web crawler, but web crawlers have much more functionality than simple extraction of text. In fact, many web crawlers have features like:
Extract HTML tags. Extract links to pages. Extract images. Extract CSS styling. Screen scrapers are capable of much more, but this is a much longer answer.

What is price scraping?

Price scraping is a common SEO practice used by many e-commerce websites that want to rank for search queries about specific products.

In an effort to rank high for those particular products, many site owners will list prices on the page that match those of competitors who are selling the same product. The thinking behind this is that these lower prices will make it seem like a better deal and entice buyers to come to their site first instead of the more expensive competitor.

Although it seems like a good idea at first, the way that this affects search rankings is not desirable. Google values price as an important factor in search rankings. If your website's prices are better than the competition, you can start to move up in search results. However, if your prices are higher than other competitors, you'll start to lose trust with customers and fall farther down the search rankings. Google is going to prefer to show customers information that's actually beneficial to them, so if they start to see that your prices are higher than competitors, it can actually harm your search engine optimization.

Some methods of price scraping include: Listing similar prices or prices that are higher/lower than competitors.99 or higher.

Creating a duplicate of a product and creating an if-this-then-that type of pricing strategy. Using tactics to make the perceived value of a product lower than it really is. The original store may offer free shipping and free returns, but if the competitor does not offer either, the store owner may offer free shipping and try to use tactics to make the store appear cheaper than it is. For example, offering free shipping will only work if your company has a good reputation with buyers, and if they are selling a product at a high price point.

However, there are many ways to use price scraping, so before we go any further, let's make sure that you know what you're getting into and understand the best practices you should be using while doing it.

What is scraping competitors pricing?

Competing directly with an existing e-commerce company can be daunting.

You have to spend a lot of time and effort to compete against an established brand that has a customer base, a distribution channel, and a brand.

You can also be too aggressive about your pricing and undercut the existing market leaders, which can damage your reputation and brand. Fortunately, scraping competitors' pricing data is quick, simple, and free. All you need is access to their website's API and some Python knowledge.

We will walk through building an API for an e-commerce website in Node.js and Python and scraping competitor pricing data for your own business.

Setting up your API. Before we get started with the actual scraping code, let's talk about setting up your API on the web store you want to scrape. If you haven't already done so, you'll want to create an account on the website you want to scrape. The best place to start is with their developer portal.

It will have instructions on how to get the necessary API keys, access tokens, and documentation. After you log into your account and click the Create API Key button, the API Key page will appear. In this page you will enter a description, API Key name, and a website URL. These are used to identify the site that you are making requests from. I am going to be requesting pricing data from Target. In this case I will be using the API Key target-api-key for Target. I will go ahead and add my API Key and Website URL. After you create the API Key and Website URL, you will be taken back to the API Key page. You'll want to copy your API Key and Website URL.

Setting up your Python API. There is a plethora of Python libraries that you can use to perform web scraping. The two I like most are Scrapy and Requests.

Scrapy is more powerful and a lot faster, but it is much harder to setup. Requests is a simple API wrapper for requests. So if you have a ton of experience using Requests, you might want to consider using that.
