Web scraping, web crawling, html scraping, and any other form of web data extraction can be complicated. Between obtaining the correct page source, to parsing the source correctly, rendering JavaScript, and obtaining data in a usable form, there’s a lot of work to be done.
Web scraping also knew as Web Data extraction / Web Harvesting / Data Crawling / Screen Scrapping is a technology that is loved by start-ups, small and big companies. In simple words, it is actually an automation technique to extract the unorganized web data into a manageable format, where the data is extracted by traversing each URL by the robot and then using REGEX, CSS, XPATH or some other technique to extract the desired information in a choice of the output format.
So, it’s a process of collecting information automatically from the World Wide Web. Current web scraping solutions range from the ad-hoc, requiring human effort, to even fully automated systems that are able to convert entire web sites into structured information. Using web scraping software’s you can build sitemaps that will navigate the site and extract the data. Using different types of selectors the web scraping tool will navigate the site and extract multiple types of data – text, tables, images, links, and more.
The site-specific web crawling websites or the price comparison websites crawl the store’s website prices, product description, and images to get the data for analytics, affiliation, or comparison. It has also been proved that pricing optimization techniques can improve gross profit margins by almost 10%. Selling products at a competitive rate all the time is a really crucial aspect of e-commerce. Web crawling is also used by travel, e-commerce companies to extract prices from airlines’ websites in real-time for a long time. By creating your custom scraping agent you can extract product feeds, images, price, and other all associated details regarding the product from multiple sites and create your own data-warehouse or price comparison site. Here is one example of trivago.com
That’s also an important aspect of web scraping where business profiles and reviews on the websites can be scrapped. This can be used to see the performance of the product, user behavior, and reaction. The web scraping could list and check thousands of user-profiles and the reviews which can be really useful for business analytics.

It has become a common practice for people to read online opinions and reviews for different purposes. Thus it’s important to figure out the opinion spamming: It refers to “illegal” activities example writing fake reviews on the portals. It is also called a shilling, which tries to mislead readers. Thus the web scrapping can be helpful crawling the reviews and detecting which one to block, to be verified, or streamline the experience.

It tracks the stock availability and prices of products in one of the most frequent ways and sends notifications whenever there is a change in competitors’ prices or in the market. In eCommerce, Retailers or marketplaces use web scraping not only to monitor their competitor prices but also to improve their product attributes. To stay on top of their direct competitors, nowadays e-commerce sites have started closely monitoring their counterparts. For example, say Amazon would want to know how their products are performing against Flipkart or Walmart, and whether their product coverage is complete. Towards this end, they would want to crawl product catalogs from these two sites to find the gaps in their catalog. They’d also want to stay updated about whether they’re running any promotions on any of the products or categories. This helps in gaining actionable insights that can be implemented in their own pricing decisions. Apart from promotions, sites are also interested in finding out details such as shipping times, a number of sellers, availability, similar products (recommendations), etc. for identical products.
This is another important use for the sales-driven organization wherein lead generation is done. Sales teams are always hungry for data and with the help of the web scrapping technique, you can scrap leads from directories such as Yelp, Sulekha, Just Dial, Yellow Pages, etc. and then contact them to make a sales introduction.

Job sites are also using scrapping to list all the data in one place. They scrape different company websites or job sites to create a central job board website and have a list of companies that are currently hiring to contact. There is also a method to use Google with LinkedIn to get lists of people by the company which is geo-targeted by this data. The only thing that was difficult was to extract from the professional social networking site is contact details, although now they are readily available through other sources by writing scraping scripts methods to collate this data. For example here is one example of naukri.com
Do you know 50% of consumers read reviews before deciding to book a hotel? Now scrape review, ratings, and comments from multiple websites to understand the customer sentiments and analyze with your favorite tool.
This is a new thing popular in the market but again for this, a lot of data is needed hence web scrapping is done for as much public data as possible because this volume of data is practically impossible to gather.
