Semalt Explains What Web Scraping Is

Dec 06, 2017

Web scraping is the process of extracting large volumes of data from different websites using a tool called website scraper. The extracted data could be saved in a designated folder or any other location. It could also be saved to a database in a table or spreadsheet format.

Content of most websites can only be viewed using a web browser. You can't save a copy for your personal use. Your only option is to copy the content manually and paste it elsewhere. Apart from being tedious and frustrating, it is also time-consuming. Imagine you have to copy all the content of a 200-paged website. It will take an enormous amount of time!

However, web scraping is the method that can automate this process. Instead of the manual copying, web scraping software or website scraper will do the job in a very short time. It will save you a lot of pain, efforts and time.

The software has the ability to scrape different elements of data from multiple web pages of different websites per your request. Currently, there are two main types of website scrapers. There are custom built ones for a specific purpose or websites. On the other hand, there are general scrapers that can be configured to work with any website. Whichever one you opt for, you only need to click a single button to extract and save some data on your local computer.

Due to the fact that the cost of custom built software is quite high, a lot of people prefer to go for generic web scraping software. However, those ones have their drawbacks too. They are very difficult to setup and use, especially for a non-technical user. And they are often difficult to learn.

This is where WebHarvy comes in handy. It was developed to cope with the difficulties which occur when using most generic website scrapers. This tool offers an intuitive, point and click interface. With WebHarvy, data extraction from any website is a matter of a couple of minutes.

The tool comes with a video clip that shows how easy it can be set up and used for your data extraction needs. After watching the video, you will learn how simple its point and click interface is. What really stands this tool out is the fact that it does not require any coding to configure. It can be configured to scrape data from any website with a few clicks of your mouse. To select the data to be scrapped, you only need to point your mouse to the data elements. To assess it, you can try out its evaluation version, and you can also watch the video demonstration too.

Reasons you should try WebHarvy:

Being a generic data scraper, it is cheaper than custom built ones
It requires no code for setting up and use
It is very easy to use even for a non-technical user
It comes with an evaluation version and a video demo
