Data-driven business decisions are key to companies that seek to stay relevant in the competitive e-commerce market. Extracting data from various websites and using this information to build a strong marketing strategy is essential for any e-commerce business.  

The main issues of web scraping for e-commerce websites are data quality and speed. Scraping at scale requires high-speed crawlers that do not compromise the quality of extracted data.

A powerful web crawler that both crawls and scrapes complicated targets, parses data, and ensures a 100% success rate without any maintenance, would be ideal for any e-commerce business. The good news is, that is exactly what Oxylabs’ Real-Time Crawler does!

But before we get to the solution, let’s have a better look at the issue. What is a website crawler and why do e-commerce websites need it?

e-commerce businesses know well what is a web crawler

What is a web crawler?

Web crawler definition is already suggested by its name. A web crawler (also known as a crawling agent, a spider bot, or a search engine bot) goes through websites and gathers information. In other words, the spider bot crawls through websites searching for information. In e-commerce, this information may include product names, item prices and descriptions.

For e-commerce purposes, a web crawler is usually accompanied by a web scraper that downloads, or scrapes, required information.

Oxylabs’ Real-Time Crawler does both – it crawls websites and scrapes information, but we will get to this tool soon.

Why use a web crawler for e-commerce websites?

Large e-commerce websites use web scraping tools to gather data from competitors’ websites. 

For example, companies crawl and scrape websites to gather real-time competitors’ price data. This allows businesses to monitor competitors’ campaigns and promotions, and act accordingly.

Another use case includes keeping up to date with the assortment on competitors’ websites. Monitoring new items that other companies add to their product lists allows e-commerce businesses to make decisions about their own product range.

Both of these use cases help companies keep track of their competitors’ actions. Having this information, companies offer new products or services. Being on top of their game is essential if businesses want to stay relevant in the competitive e-commerce market. 

Challenges of web crawling

We already discussed web crawling advantages for your e-commerce business, but this process also raises challenges. 

First of all, web crawling requires a lot of resources. In order to gather wanted data from e-commerce websites, companies need to develop a certain infrastructure, write scraper code and allocate human resources (developers, system administrators, etc.) 

Another issue is anti-bot measures. Most large e-commerce websites do not want to be scraped and use various security features. For example, websites add CAPTCHA challenges or even block IP addresses. Many budget scraping and crawling tools on the market are not efficient enough to gather data from large websites. 

Some companies use proxies and rotate them in order to mimic real customer’s behavior. Rotating IPs works on small websites with basic logic, but more sophisticated e-commerce websites have extra security measures in place. They quickly identify bots and block them.

One more challenge: the quality of the gathered data. If you extract information from hundreds or thousands of websites every day, it becomes impossible to manually check the quality of data. Cluttered or incomplete information will inevitably creep into your data feeds. 

How to avoid all these challenges?
