web scraping

The present trends in web scraping tools

Recently I got a question from one of the blog readers. After I replied to it, I decided to share it with a wider audience.
Question:

Hi,

I found your scraping.pro site and found it very helpful, then realized the web scraper solutions rating was from 2014.  What is the best solution for today?   I have lots of sites I need to scrape, mainly search then drill-down sites.   I would like to be able to schedule the scraping to run on a daily basis.  Is there a direction you could point me?  I’m a seasoned developer by trade but am seeing all these point and click solutions (e.g. import.io) and am wondering if I should stick with Node.JS or .NET or if I should investigate some of these GUI scrapers of today.

Dexi.io – how to improve performance

dexi-improve-speedIntro

Some may argue that extracting 3 records per minute is not fast enough for an automated scraper (see my last post on Dexi multi-threaded jobs). However, you should realize that Dexi extractor robots behave like a full-blown modern browser and fetch all the resources that crawled pages load (CSS, JS, fonts, etc.).
In terms of performance, an extractor robot might not be as fast as a pure HTTP scraping script, but its advantage is the ability to extract data from dynamic websites which require running JavaScript code in order to generate a user-facing content. It will also be harder for anti-bot mechanisms to detect and block it. more…

Reliable rotating proxies for business directories scrape

logo_rotating_proxiesWe’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 busines directories, their web servers can identify repetative 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 rotatign proxies pool at each request. more…
