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.

  1. Rate limit
    Limit the crawling rate for LinkedIn. The acceptable approximate frequency is: 1 request every second, 60 requests per minute.
  2. Public pages only
    LinkedIn allows for bots only public pages; pages that are private cannot be crawled.

Most popular web scraping targets and how to scrape them

  1. 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.
  2. 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.
