Recently we’ve performed the Yelp business directory scrape for acquiring high quality B2B leads (company + CEO info). This forced us to apply many techniques like proxying, external company site scrape, email verification and more.

Let me tell you what you already know! Octoparse is a great web scraping tool! But like every great tool, it’s got its limitations. At times, you may wonder if there are any alternatives to Octoparse. We wondered the same and put together this blog to provide you a short list of Octoparse alternatives along with their features and distinguishing factors. Let’s get started!
Selenium Web Scraping in simple words

Answer: A picture is better than 1000 words:
So, you make a program with Python, PHP, JAVA, Ruby and whatever language you use in order to browse(), select(), click(), submit(), save(), etc., target web pages.
Linkedin scrape guide lines
The LinkedIn crawl success rate is low; one request that a bot makes might require several retries to be successful. So, here we share the crucial Linkedin scraping guide lines.
- Rate limit
Limit the crawling rate for LinkedIn. The acceptable approximate frequency is: 1 request every second, 60 requests per minute. - Public pages only
LinkedIn allows for bots only public pages; pages that are private cannot be crawled.
- Online marketplaces
In the marketplaces people offer their products for sale. Similar to garage sales, but online. (eg. eCrater, www.1188.no).
Easy to scrape since they are usually free and do not tend to protect their data. - Business directories
The usually huge online directories targeted at the general audience. (eg. Yellow Pages). They do protect their data to avoid duplication and loss of audience. See some posts on this.
