If you ignore this, then it might give you incomplete or even crash scraper.

· IP based blocking: Let’s understand this using an example. If you have built a web scraper in Python so as to scrape the product prices from any ecommerce website, then if you run it from your local system, it would result in the scraper to fail. This is because wet scrapers give too many requests at a time which blocks the IP and this problem can be solved by using reliable proxy services.

· CAPTCHA based blocking: Most of the E-Commerce companies use CAPTCHA solutions which identify non-human behaviour and blocks the web scrappers. It is one of the most common challenges that arise in the way of web scraping. Even though if you solve it and resume the process, they can still slow down the scraping process.

· Honeypot traps: Some of the web designers install Honeypot traps web scrappers. They may be the link that normal users can't see but a bot can see. The web scraping services should design the scrappers so that it can deal with honeypot traps.

Top 4 Methods Used Against Web Scraping

Even though web scraping services are widely used across most of the industries, still most of the websites do not appreciate it and they develop new anti-scraping methods on a routine basis. The main reason behind is that aggressive web scraping can eventually slow down the website for regular visitors. And in the worst case scenario, it can even result in a denial of service. So as to prevent you from scraping their websites, companies use a number of strategies. So in this blog, we are going to talk about the methods that are used against web scraping as it will prevent your IP address from getting blocked.

Let’s get started!

IP rate limiting: This is also called request throttling which is one of the most common anti scraping methods. One of the good practices of web scraping is to respect the website and scrape it gradually. This will help you in avoiding the monopolising of the bandwidth of the website and regular visitors will also have a smooth experience of the website. Request throttling refers that there are more number of actions on the website and any request over this limit will not get an answer.

Blocking the bot scrapers: Some websites are fine with a simple regulation of website scraping but other websites try to prevent it all together. They use a number of tactics to identify and block the scrapers like CAPTCHAs, user agent, entire IP range, AWS shield and more.

Providing fake information: Are you familiar with honeypots? Honeypots are those links that only bots find and visit. But there are some other techniques as well that only bots see. This is known as cloaking. Cloaking is a hiding techniques that shows and altered page of the website. The bots collect information without knowing that it is fake. This method is an accepted by the search engine and the websites does use this method are at the risk from getting removed from the index.

Making the data collection even harder: Some of the websites modify their HTML mark-ups at regular intervals of time in order to protect the data. Scraping bots try to find data that it found last time. By changing the HTML mark-ups, the websites try to confuse the scraping bots and make it harder to find the required data. In this case, individuals are left confused and this is where web scraping services come into role where professionals identify the obstruction and overcomes it in an easier way. The programmers can even manipulate the code but still the desired information can't be obtained.
