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.

Get and pass CSRF token using python requests library

 

import sys
import requests
URL = 'https://portal.bitcasa.com/login'
client = requests.session()

# Retrieve the CSRF token first
client.get(URL)  # sets cookie
if 'csrftoken' in client.cookies:
    # Django 1.6 and up
    csrftoken = client.cookies['csrftoken']
else:
    # older versions
    csrftoken = client.cookies['csrf']

# Pass CSRF token both in login parameters (csrfmiddlewaretoken)
# and in the session cookies (csrf in client.cookies)
login_data = dict(username=EMAIL, password=PASSWORD, csrfmiddlewaretoken=csrftoken, next='/')
r = client.post(URL, data=login_data, headers=dict(Referer=URL))

Business directory simple scraper (python) at pythonanywhere

business directoryMy goal was to retrieve data from a web business directory.

Since the business directories scrape is the most challenging task (beside SERP scrape) there are some basic questions for me to answer:

  1. Is there any scrape protection set at that site?
  2. How much data is in that web business directory?
  3. What kind of queries can I run to find all the directory’s items?

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.
