They are just like traps to detect scraper by directing them to blank pages.

Honeypots are links that are invisible to normal visitors but are there in the HTML code and can be found by web scrapers. However, with Octoparse, this can be easily dealt with as Octoparse can directly access the data from the target website in its built-in browser then analyze it automatically. Solution: When an HTTP Post request is sent, there is no doubt that JavaScript encryption will make it more difficult to scrape. Crawlers that written in JavaScript can be “tricked” easily. JS encryption tech is used to keep content safe from being scraped. More details can be found in Extract data behind a login.ĥ.

inputting username and password as part of the workflow. Solution: Octoparse works by imitating human browsing behaviors, so when login is required to access the data needed, you can easily incorporate the login steps, ie. Take Instagram as an example, without login, visitors can only get 20 comments under each post. Login can be regarded as permission to gain more access to some specific web pages, like Twitter, Facebook, and Instagram. Octoparse local extraction allows users to set up proxies to avoid being blocked. When an extraction task is set to be executed in the Cloud, requests are performed on the target website through various IPs, minimizing the chances of being traced. Octoparse Cloud Service, for instance, is supported by hundreds of cloud servers, each with a unique IP address. Solutions: Many servers, such as VPNs, can help you to get rotated IP.

You need to create a pool of IP addresses and use them randomly to route your requests through a series of different IP addresses. Of course, if you use a single IP set up in the proxy server, it is still easy to get blocked. It allows you to send requests to websites using the IP you set up, masking your real IP address. A proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers ( Proxy server). To avoid sending all of your requests through the same IP address, you can use proxy servers. When a site detects there are a number of requests coming from a single IP address, the IP address can be easily blocked.

Tools like Octoparse does provide cheaper alternatives with a bit compromised results.

Solution: With the surge of the image recognition tech, conventional CAPTCHA can be cracked easily, though it costs a lot. Type 3: Select the specified images from all the given images. Solution: We can set random time intervals between requests, i.e., we can either add “sleep” in the code when writing a script or set up wait time when using Octoparse to build a crawler. Websites can track your access speed easily and once the system finds you are going through the pages too fast, it will suspect that you are not a human and block you by default. Most web scraping bots aim to fetch data as quickly as possible, however, this can easily get you exposed as a scraping bot as there’s no way a real human can surf the web so fast. In this article, we will see some common anti-scraping systems and discuss the corresponding solutions to tackle them.

Luckily, for those who use web scraping responsibly, there are solutions to bypass anti-scaping techniques and avoid being blocked by anti-scraping systems. As a result, many websites “protect” themselves using anti-scraping mechanisms to avoid being “attacked” by web-scraping programs. While a crawler goes un-restrained and sends an overwhelming number of requests to a website, the server could potentially crash down. It can be used to help people of all fields capturing massive data and information from the internet.Īs more and more people turn to web scraping for acquiring data, tools like Octoparse are becoming popular as they help people to quickly turn web data into spreadsheets.ĭuring this process, however, web scraping does put some extra pressure on the target website. Web scraping is a technique that enables quick in-depth data retrieving.
