Examples are lazy loading images, infinite scrolling and show more info by clicking a button via AJAX calls.

Many websites apply AJAX to update dynamic web content. It can even execute customized workflow under preset situations. Octoparse allows users to set up auto-retry or retry loading when certain conditions are met to solve the issues.

But scraping may be broke up as the scraper does not know how to deal with such an emergency.

That is not a problem when humans browse the site as they just need to reload the web page and wait for the website to recover. Websites may respond slowly or even fail to load when receiving too many access requests. Octoparse uses XPath to precisely locates items to click or to scrape, which largely reduces the chance of falling into the trap. Once a scraper falls into the trap, the website can use the information it receives(e.g. The traps can be links that are invisible to humans but visible to scrapers. Honeypot is a trap the website owner puts on the page to catch scrapers. Although the technologies to overcome CAPTCHA can help acquire continuous data feeds, they could still slow down the scraping process a bit. Many CAPTCHA solvers can be implemented into bots to ensure non-stopping scrapes. Octoparse Cloud extraction utilizes multiple IPs to scrape one website at the same time to not only make sure one IP would not request too many times but also keep the high speed.ĬAPTCHA(Completely Automated Public Turing test to tell Computers and Humans Apart) is often used to separate humans from scraping tools by displaying images or logical problems that humans find easy to solve but scrapers don’t. There are many IP proxy services like Luminati, that can be integrated with automated scrapers, saving people from such blocking. The website would either totally ban the IP or restrict its access to break down the scraping process. It typically happens when a website detects a high number of requests from the same IP address. IP blocking is a common method to stop web scrapers from accessing data of a website. You can modify the workflow easier to adapt to the new pages. Octoparse uses customized workflow to simulate human behaviors so that to deal with different pages. Sometimes even a minor change in the target website requires you to adjust the scraper. Since web scrapers are set up according to a certain design of the page, they would not work for the updated page. Moreover, websites periodically update their content to improve the user experience or add new features, which often leads to structural changes on the web page. When you need to scrape multiple websites, you need to build one scraper for each website. Web page designers can have their own standards to design the pages, so web page structures are widely divergent. Most web pages are based on HTML ( Hypertext Markup Language). Complicated and changeable web page structures

If the owner still disagrees, it’s better to find an alternative site that has similar information.Ģ. If you find it disallows for scraping via its robots.txt, you can ask the web owner for scraping permission, explaining your scraping needs and purposes. The first thing to check is that if your target website allows for scraping before you start it.

However, many challenges, such as blocking mechanisms, will rise when scaling up the web scraping processes, which can hinder people from getting data. More and more people hunger for extracting data from multiple websites to help with their business development. Web scraping has become a hot topic among people with the rising demand for big data.
