Recently I was asked to help with the job of scraping company information from the Yellow Pages website using the ScreenScraper Chrome Extension. After working with this simple scraper, I decided to create a tutorial on how to use this Google Chrome Extension for scraping pages similar to this one. Hopefully, it will be useful to many of you.

Crawler vs Scraper vs Parser
In the post we share the differences between Crawler, Scraper and Parser.
After a great deal of work, the Death By Captcha developers have finally released their new feature to the world – new Recaptcha v3 Support.
As you may already know, the Recaptcha v3 API is quite similar in many ways to the previous one used to manage tokens (Recaptcha v2). In Recaptcha v3, the system evaluates or scores each user to determine if it’s bot or human, then it uses the score value to decide if it will accept or not the requests from said user. Lower scores are identified as bots. Check this link to verify the API documentation and download client based sample codes.
With very competitive pricing, Death By Captcha is at the cutting edge of solving tools in the market. Check it out – you can receive free credit for testing from this LINK; ping the service with the promo code below to receive your captchas.
Use the promo code “Scrapepro” and you’ll get 3k Captchas credit for free.
P. S. See the ReCaptcha v2 test results.

Smartproxy Review
Getting precise and localized data is becoming difficult. Advanced proxy networks are the only thing that is keeping some companies running intense data gathering operations.
Residential proxies are in extremely high demand, and there are only a few networks available that can offer millions of IP addresses around the world.
Smartproxy is one of those networks, rapidly growing to offer the best product in residential and data center proxies.
Anything free always sounds appealing. And we are often ready to go an extra mile to avoid expenses if we can. But is it a good idea to choose the free option when it comes to using proxies for data scraping? Or should you stick to the paid ones for better results?
Let’s weigh all the pros and cons to see why you should consider using residential IP providers like Infatica, Luminati, NetNut, Geosurf and others.
General Data Protection Regulation or GDPR: enforcement date – 25 May 2018. The GDPR covers the matter of online user data privacy rules for electronic communication and data protection. The regulation includes modern communication messengers and services, eg. Skype, Viber, Gmail, etc., that have not been previously mentioned in the former EU e-communication directives.
“Privacy is guaranteed for content of communication as well as metadata (e.g. time of a call and location) which have a high privacy component and need to be anonymised or deleted if users did not give their consent, unless the data is needed for billing.”
See the infographic on GDPR or the main elements of GDPR in EU.
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.
We’ve already written about suitable proxy servers for web scraping. Now we want to focus our readers on those for the huge/mass quantities data records scrape, particulary from the business directories. When scraping business directories, their web servers can identify repetitive requesting and put you on hold by looking at the IP address that is used for frequent http requests. Proxy rotation web service is the means for repeatedly changing IP address. Thus, target web server can only see the random IP addresses from rotating proxies pool at each request.
Recently I’ve got a note with the question on search engine queries through the web scraping software.
“I’m looking for a scraper program that can initiate search queries in a search engine automatically, using proxies would be an added benefit if possible.” – Mike
As anyone who has spent any time on the scraping field will know, there are plenty of anti-scraping techniques on the market.

If you think we’ve missed any out, please let me know in the comments below!
