We’ve already introduced you to the theory behind the new NO CAPTCHA reCAPTCHA v2, but now we come to the practical integration part. Here we’ll share how to insert and configure “NO CAPTCHA reCAPTCHA” into a web page.

No CAPTCHA reCaptcha challenge
Sooner or later a new generation of spam protection methods will emerge to block all unwanted site visitors. The recently launched Google “No CAPTCHA reCaptcha” or ReCaptcha v2.0 could just be such a method.
This new behaviour analysis tool is getting more and more attention both from the site owners and from scraping engines who are trying to break it. Since Google does not reveal any secrets of its operation, we want to share with you the techniques used in this new smart analysis CAPTCHA that determines between bot and human. Let s look inside.
Recently I received a question in my mail box about scraping data aggregate sites (aka yellow pages) or business directories.
I replied to him directly, but our conversation on business directories was an interesting one that I thought you guys would find useful.
Here’s the question:
I am interested in scraping the database in such a website www.1881.no. My guess is that I would need a webdriver, like Selenium to do the job. I am very newbie to this field, but I believe if given some pointers, I can get some data out.
Could you please provide me with pointers on how to extract data from this website.

As a generic answer, I’ll provide you with some basics of scraping those business (and private life) directories.

Q&A with ScrapeHero
In this post we’d like to share an interview with a young service called ScrapeHero. We’ve interviewed Tony Paul (marketing head) and this is what he had to say.
Here we come to the next anti-scrape tool, called CloudFlare, former ScrapeShield.
CloudFlare
The CloudFlare app has been developed by CloudFlare to guard a site’s content. Its features are limited number, but it’s still an interesting tool to look at for anyone interested in web scraping.
Here I’d like you to get familiar with an online scraping protection service called BotDefender. It’s interesting both to know how to use it (in case you want to protect your data) and to understand how it works in case you ever come across it while collecting data.
