I’ve already written about how the new No CAPTCHA ReCaptcha works, and even had some success breaking it with an iMacros’ browser automation. But, the latest scraping tools are – for most part – driven by Python, so now I want to try the same experiment with Selenium + Python.

Professional data extraction requires adequate proxying to keep anonymity of scraping robots. When attempting to extract large data sets (over 1M records, ex. business directories) reliable and fast proxy service is needed.
Sequentum has released the Nohodo proxy service integration for Content Grabber. Nohodo provides a free account for Content Grabber users (up to 5000 requests/monthly for free). The feature is available for both trial users and regular customers. Here’s how it works… more…
Sooner or later a new generation of spam protection methods will emerge to block all unwanted site visitors. The recently launched Google No CAPTHCA reCaptcha 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. more…
In the age of the modern web there are a lot of data hunters – people who want to take the data that is on your website and re-use it. The reasons someone might want to scrape your site are incredibly varied, but regardless it is important for website owners to know if it is happening. You need to be able to identify any illegal bots and take necessary action to make sure they aren’t bringing down your site. Not all bots are malicious (think search engine bots) so I’ve outlined some criteria for site owners and developers to use to identify if and how their site is being scraped.
Suppose I run a query to import.io API:
$url = "https://query.import.io/store/connector/" . $connectorGuid . "/_query?_user=" . urlencode($userGuid) . "&_apikey=" . urlencode($apiKey);
“HI there can you please tell me that what are connector-guid, user-guid and api key in below given code and how to get them for any website?”
Recently Import.io introduced a new extraction technique called Magic. The Magic scraping method works be attempting to scrape all the information off the page automatically and in one shot. We covered it in another post early last year. When we covered it back then, we noted a few issues:
- The scraper only works on pages with more than one row of data like a search results page, category pages and etc.
But now Import.io has released a second version of Magic which seems to have dealt with those obstacles. Not only that, but they have released an API for Magic that lets you see what’s going on behind the scenes. more…
In this post I want to let you how I’ve managed to complete the challenge of scraping a site with Google Apps Script (GAS).
The challenge was to scrape arbitrary sites and save all the site’s pure text (stripping all the html markup) into a single file. Originally I was going to use python and PHP solutions, but then I thought I’d try using Google App Script instead. And it turned out pretty well. more…
