How to Scrape Data from Linkedin Using Proxies

Scrape LinkedIn Using Proxies never get blocked!

With over 500 million users, LinkedIn is the digital Rolodex of the modern age. If you don’t have an account you should probably get one. You can rub shoulders with major players in your industry, creep on old high school acquaintances, and strategize your next business move.

That’s all for the normal user of LinkedIn, which I am, and which you should be.

However, for the scraper, LinkedIn has an entirely different meaning. Instead of connecting manually with people in an industry, scrapers see LinkedIn as a gold-filled mine of personal information. A mine with 500+ million (and growing) nuggets, all of which can be harvested in a variety of ways.

Then there are company profiles on LinkedIn, which is separate from individual users and adds an entire other element for a scraper.


Why Scrape LinkedIn?

The answer should be clear: to get all that information. User profiles have names, email addresses, industries, skill competencies, etc. Companies have a number of employees, job postings, current employees, and a host of other important data.

LinkedIn is a literal representation of people and companies in the workforce, and they keep their info up to date. This data is incredibly valuable.

Of course, you can’t scrape all the data I listed above. But you can scrape some of it.


Does LinkedIn Allow Scraping?

Let’s all yell “NO!” together so the point gets across. LinkedIn is very, very against scraping of any kind. It recognizes the worth of its customers in terms of analytics and privacy and will continue to fight tooth and nail to keep scrapers off the site. You can read it’s clear statement titled “Prohibition of Scraping Software” to get the gist.

Linkedin Prohibited Software and Extention

While that language is solid, this subject is best illustrated by the lawsuit LinkedIn took out against 100 anonymous data scrapers who did what you’re trying to do but did it poorly. The verdict of the case has not been decided at the time of writing, and it brings up many issues around scraping that are beyond the purview of this article.

The point I’m trying to make is that if you do plan to scrape LinkedIn, be very cautious. They really don’t want you to do it, so if you plan to you have to do it right.


How to Scrape LinkedIn

Doing it right consists of many factors. You need to think about:

  • The applications required to do the scraping
  • The parameters you need to set in the applications
  • The type of pages you will scrape on LinkedIn (public or private)
  • The types of proxies to use, and how many proxies to use

LinkedIn Crawling Applications

There are specific applications meant for LinkedIn and LinkedIn alone — like Octoparse. Then there are multi-functional tools like Scrapebox (Good for public profiles).

How to scrape linked in profile using Octoparse

.To use Octoparse to scrape LinkedIn profiles, you will need to do the following:

  1. Install Octoparse on your computer.
  2. Go to LinkedIn and log in to your account.
  3. Search for the profile you want to scrape and open it in your browser.
  4. Click on the “Extract” button in Octoparse and select “Advanced Mode” from the dropdown menu.
  5. Use the built-in selector tool in Octoparse to select the data you want to scrape from the LinkedIn profile.
  6. Click on the “Start Extraction” button to begin scraping the LinkedIn profile.
  7. Once the extraction is complete, the data will be saved to a file that you can access and use as needed.

Keep in mind that scraping LinkedIn profiles may violate the website's terms of service, so be sure to check their terms of service before using Octoparse for this purpose.

Choosing an application is important, as many of them cost money. You’ll want to have a full
understanding of the software itself, and then what you’re trying to get out of LinkedIn in order to make a solid return on your investment.

How to scrape linked in profile using Python

To scrape LinkedIn profiles with Python, you will need to use a web scraping library such as BeautifulSoup. Here are the steps you can follow to scrape LinkedIn profiles with Python:

  1. Install the BeautifulSoup library by running the following command in your terminal:
pip install beautifulsoup4
  1. Import the BeautifulSoup library and other required libraries into your Python script:
from bs4 import BeautifulSoup
import requests
  1. Use the requests library to make a GET request to the LinkedIn profile page you want to scrape. For example:
URL = "https://www.linkedin.com/in/username"
response = requests.get(URL)
  1. Parse the HTML content of the LinkedIn profile page using the BeautifulSoup library. For example:
soup = BeautifulSoup(response.content, "html.parser")
  1. Use the find() or find_all() method of the BeautifulSoup object to select the specific elements on the page that contain the data you want to scrape. For example, if you want to scrape the user's name, you can use the following code:
name = soup.find("h1", {"class": "pv-top-card-section__name"}).text
  1. Extract the data from the selected elements using the appropriate methods, such as text or get(). For example, if you want to extract the user's job title, you can use the following code:
job_title = soup.find("h2", {"class": "pv-top-card-section__headline"}).text
  1. Repeat steps 5 and 6 for each piece of data you want to scrape from the LinkedIn profile.
  2. Save the scraped data to a file or database for future use.

Keep in mind that scraping LinkedIn profiles may violate the website's terms of service, so be sure to check their terms of service before using Python for this purpose.

Parameters within the Application Need to note!

Once you’ve settled on an application you’ll need to adjust two key settings inside it. This is generally true for all scraping procedures, but specifically for LinkedIn as it is more sensitive than other websites.


1. Threads

Threads in scraping software details the number of open connections you are using to scrape. The more threads the faster the scrape; the more threads the faster you will get flagged and banned.

The very cautious use one thread per proxy. That’s what a true human does, so anything more than that will, at some point, become suspicious. However, plenty of scrapers use up to 10 threads per proxy.

Due to LinkedIn’s extreme policy against scraping, I recommend staying to the single thread per proxy. Yes, it will slow results and cost more in the long run. In my view, those are costs built into scraping LinkedIn and avoiding a lawsuit.


2. Timeouts

The second major factor in adjusting your application’s scrape settings is timeouts. Timeouts are the literal amount of time it takes for a server to respond to a proxy before the proxy starts a new request.

If your timeouts are set to 10 seconds, your proxy will send another request for information from the server after 10 seconds of it not responding.

Many scrapers set the timeout very low: 1 or 2 seconds. This produces a huge number of results because it creates new requests for information often, meaning you get results more often.

Don’t do this. Set your timeouts high, between 30-60 seconds. This gives the server a solid pause before that particular proxy sends another request.

Think of it like a human: does a human reload a website’s home page every second if there is lag? Maybe, but they don’t do it a thousand times in a thousand seconds on repeat.

By setting your timeouts high you avoid a lot of the detection by LinkedIn and don’t overwhelm them with repeated requests.


Scraping Public Profiles on LinkedIn Through Search Engines

Moving away from the applications let’s get into LinkedIn itself. LinkedIn is primarily used as a private network. To see most of its information you have to create an account, log in, and start connecting with people.

Scraping on LinkedIn Through google

However, it has plenty of public pages. These can be viewed without an account, and can, therefore, be scraped without logging in, for you can easily view the public LinkedIn profile without an account.

You are free to scrape public pages on LinkedIn like any normal scrape that starts with a search engine, You have to enter the correct search terms, like including “LinkedIn.com”, which will generate results in Google that point to specific LinkedIn pages.

Your scraper can then access the information available on these public pages and return it to you. You’ll be scraping both Google and LinkedIn in this context, so you’ll want to be careful not to set off the alarm bells for either of them.

You can get very specific with this, searching for an industry sector of company pages on LinkedIn through an engine, like Microsoft or Google or Apple. You would do this by scraping for “Apple LinkedIn” and then scraping the results.

This will only give you public pages though, and you may not want to be limited.


Use Rotating Backconnect Proxy to anonymous Scraping

It's not difficult to Scrape public files on LinkedIn on Google, Even just use Scrapebox that can help you handle it in many cases.

So, if you just want to Scrape public profiles the best solution is to use backconnect rotating proxies for Scraping data on google and LinkedIn!

  • Smartproxy – 40+ million residential IPs in proxy pool

  • Shifter – 31+ million residential IPs in proxy pool

Scraping Private Profiles on LinkedIn

The scraping of private accounts is the specific line in the sand that LinkedIn doesn’t want you to cross. It’s not happy that you scrape public pages, but they’re public, and there’s not much they can do about it from a legal standpoint.

Scraping Private Accounts

Private pages are another matter. When a person signs up with LinkedIn they are told their information will be kept private, not sold to other companies, and used for internal use only. When a scraper comes along to grab that information LinkedIn has a major problem on its hands.

I don’t condone this activity if you’re using your scrape to sell an individual’s information. This basically means you’d be bypassing LinkedIn’s privacy clause, harvesting personal information from people, then selling it to companies for a profit. Not the coolest thing to do.

There are other reasons to scrape this information though. Maybe you’re on a job hunt and want to find programmers in a specific city or available jobs in a new state. You can scrape for research, too. Either of these seems fine to me, but the for-profit model doesn’t.


Create Accounts

The way to scrape private pages on LinkedIn is to create an account. Once you do this and
actually log into LinkedIn you’ll be able to search as much as you want. Remember, this account isn’t for connecting with people, but as an access point to LinkedIn for a scrape.

Linkedin Accounts for scraping

To do this I recommend Octoparse. Their software allows you to log in to LinkedIn with an account and apply specific searches and scrapes with a drag and drop interface, all while showing you the LinkedIn page you’re on. It’s very nice visually if a little clunky to use.

You could figure out a way to do it with other applications but it won’t be as easy.


Search and Harvest

After creating the account, just figured out what you want to search. If you try and find Microsoft employees a ton of people will come up. You can have the scraper harvest any information that is available to you as a non-connection. Basically name, position, sometimes the email address.

Much of the information is still private unless you connect with people, and if you do that you’re basically just running a normal LinkedIn account.

Use Dedicated Proxy Per Account

By doing the above you are using a direct automation tool within LinkedIn. The potential for getting caught here is huge, so make sure to follow the threads and timeouts rules above.

Also, make sure you’re using one proxy IP address to create the account, and then scrape on that account. This is all about appearing like a human. Most humans don’t access LinkedIn from a different IP address every few hours. They access it from one IP address: their home address.

Use a Proxy Per Account

If you create the account with a proxy IP, use the same proxy IP to scrape on the account, and set all your parameters correctly you will greatly reduce the chances of getting blocked or banned.


Types and Number of Proxies

The final element in all this is the types of proxies you use, and how many of them you use. This coincides pretty heavily with your budget because more proxies (and better ones) equals more cash. Keep that in mind for this whole process.

If you want to scrape private profiles of Linkedin accounts, you have to use dedicated proxies for each account! For you have to log in to views others private profiles, and Linkedin is so strict to IP,When you change the IP to login to account, you have to verify via email!

You want elite private proxies for scraping LinkedIn. With a lawsuit underway, LinkedIn is not kidding around about punishing scrapers. This means you’ll want elite private proxies and only elite dedicated proxies.

These proxies offer the most anonymous and secure HEADER settings out of all the proxy types, and give you unfettered access and speeds. Shared proxies or free proxies (even lesser private proxies) are simply not secure or fast enough to do the job.

You’ll also want to test your proxies to make sure they work with LinkedIn. Due to LinkedIn’s
anti-scrape stance, it has a large list of blacklisted IPs. If your proxies are in this list they won’t work at all. Contact your provider to get these details, or test it out for yourself and then chat with them.


Number of Proxies

Depending on the size of your scrape you’re going to need a number of them. The general rule of thumb is the more proxies the better, especially when scraping a difficult website.

If you stick to a single proxy per account and want to harvest a lot of data quickly, consider 50 accounts and 50 proxies as a place to get started.

If you want to do more proxies per account (which I don’t recommend), grab somewhere in the 100-200 range and rotate them often so they don’t get noticed, then blocked, banned, and blacklisted.

The fewer proxies you have the more often they’ll be detected. This is always an experiment, so make sure you test everything.


Wrapping Up

Scraping LinkedIn requires proxies and moxie. You have to really want to do it because it’s not going to be easy, and could result in blacklisted IPs or a lawsuit. As such, take precautionary measures. Understand why you’re scraping LinkedIn, and then reach those specific goals carefully.
