Semalt Provides The Test Results Of Web Scraping Tools
Every user faces two options when they want to use web scraping tools. They either use an off-the-shelf web scraper or a custom scraper. While a custom scraper is a better option, a lot of people shy away from it because of its high cost. The tool has to be developed to suit your business and preferences, so it requires a lot of work. On the other hand, off-the-shelf web scrapers are too generic since they are designed for general web scraping tasks. They are usually better at some web scraping projects and do shoddy jobs at others. To help you make the right choice, some web scrapers were subjected to thorough web scraping tests and the results have been displayed below.
Test Criteria The web scrapers were tested on the following common data extraction tasks. They were tested on their ability to scrape tabular reports, text lists, and login forms. In addition, the web scrapers were also tested on their ability to extract data from dynamic web pages built on AJAX. This is usually one of the most dif cult tasks for many web scrapers. Their ability to handle Captcha was also put to test. Lastly, they were tested on their ability to handle block layout. http://rankexperience.com/articles/article2472.html
