How to scrape LinkedIn Post Likers with Python [2024 Edition]

200 countries all over the world, more than a billion (!) members: LinkedIn is a dense and active social media.

Every day, millions of posts, and millions of (enthusiastic) post likers.

In this article, we will see how to scrape likers of a LinkedIn post with Python and requests. And export all of it into a properly formatted CSV file.

What data points will we recover using this Python Linkedin Post Likers Scraper?

We will recover all publicly visible datapoints:

1. Name
2. Image
3. Reaction (LIKE, PRAISE etc.)
4. Connection
5. Job
6. Profile URL

Why do people need to scrape LinkedIn Post Likers?

But before getting to the heart of the matter, one question arises: why scrape people who like a post on Linkedin?

There are two main use cases:

1. Know who is interested in you
2. Steal your competitors’ audience

Know who is interested in you

From the likers of a post, you can identify the type of profile that is interested to you.

For example, I asked ChatGPT to compile a list of the main business functions:

And then I count the number of functions that appear in the job titles:

We find a large proportion of engineers, and this is quite expected. Bill Gates is the creator of Microsoft, a computer giant, and the post concerns the world of energy.

Steal your competitors’ audience

We started with vanilla data. It is time to tackle something more ethically questionable but practiced by all in a free market economy: stealing a competitor’s audience.

🥷

Retrieve your competitor's LinkedIn URLs, and contact them automatically with for example the LinkedIn Message Sender of PhantomBuster.

Is it legal to scrape LinkedIn?

Let's be frank: LinkedIn doesn't like it.

In the general conditions of use of the site, it is explicit: you are prohibited from using automated collection tools, under penalty of seeing your account banned.

However, the data on LinkedIn is public data. And it is completely legal to scrape public data online.

Whether by hand, or using an automated tool.

LinkedIn hosts this data, but does not own it.

In any case, this is what a Supreme Court in the United States decided in 2022. In the case opposing HiQ Labs to… LinkedIn themselves.

Prerequisites

Before running the code, you will need to install requests via pip.

$ pip install requests

It is the most used Python library, with 51K+ stars on GitHub. It allows you to browse the Internet with Python. Magical.

Complete Code

And here is the complete code, also available on Github right here: linkedin_post_likers.py.

Step by step Tutorial

OK and now how to use it?

Unfortunately, for ease of development reasons, this script is semi-automatic. That is to say, you must slightly modify the script before launching it.

Indeed, the part login is always delicate, with its captchas and double authentication.

So we made it simpler: just log in to LinkedIn and retrieve the li_at cookie.

Easy and error-free.

We will do this in 5 very simple steps:

1. Download the file
2. Installer requests
3. Retrieve the li_at cookie
4. Retrieve the URL of the LinkedIn post
5. Start the machine

Download file

First, we will download the Python file.

Retrieve the file either on this page or via the address mentioned above: linkedin_post_likers.py.

Click on Download ZIP then unzip the file.

Install requests

As suggested earlier, install requests simply as follows:

$ pip install requests

Retrieve the li_at cookie

When you log in to LinkedIn, the site assigns you a session cookie. This cookie certifies that it is really you, you show your white paw.

We're going to go get it.

First of all, go to LinkedIn, and identify yourself using your email and password.

Then download the extension Get cookies.txt LOCALLY from the Chrome Store. This extension will allow us to quickly retrieve the li_at cookie that we will need next.

Finally, once on LinkedIn, collect the li_at cookie by clicking on the extension:

And replace in the script at the variable LI_AT.

# Update your LI_AT below
# vvvvvvvvvvvvvvvvvv

LI_AT="AQEFARABAAAAAA582xIAAAGN-ncr4gAAAY4eg6_iTQAAs3VybjpsaTplbnRlcnByaXNlQXV0aFRva2VuOmVKeGpaQUFDZGcvUE9TQ2FlMFBHRkJETkVmYjlDU09JWWZlTmJ4V1lJWFhtL0M4R1JnQzJmZ25FXnVybjpsaTplbnRlcnByaXNlUHJvZmlsZToodXJuOmxpOmVudGVycHJpc2VBY2NvdW50OjEyMjE3Nzk0OCwxOTYxMTA0ODQpXnVybjpsaTptZW1iZXI6MzA0NzQwNDUzCJCilw8ToxGdMzR3SPl1TqCZTknBs1duxKFK7L6EsksXVkem6Xq-ZOZRNLuEfpl_6xFR2zcQqQWMPlKPlKJq5AzO8H1mffd4EgVN-MaTu0UEMZdnhd6sLxssWLyAOjDkvPpeab6WM2CfbRitkYiIqyurdTCQrck9Cr3ghlmSBGZlFScZ7xRXu3Xpn3q07cYgenQ5vw"

Retrieve the URL of the LinkedIn post

Go to LinkedIn, and retrieve the URL of your LinkedIn post.

At the post level, simply click on the three vertical dots, and click Copy link to post.

Paste this URL into the URL variable.

# Add you URL below
# vvvvvvvvvvvvvvvvvv

URL = "https://www.linkedin.com/posts/williamhgates_us-carbon-emissions-fell-in-2023-as-coal-activity-7156808265396285440-EV0P/?utm_source=share&utm_medium=member_desktop"

Start the machine

And now it's time to run the script!

Open the command line, move to where the script is and launch the machine.

You will see information about

1. retrieving the csrf_token at the beginning
2. recovery of post identifiers
3. collecting reactions 50 by 50

$ python3 scrape_name_of_likes_linkedin.py
[0] starting https://www.linkedin.com/posts/williamhgates_us-carbon-emissions-fell-in-2023-as-coal-activity-7156808265396285440-EV0P/?utm_source=share&utm_medium=member_desktop

[3] collecting reviews
0 ok
50 ok
100 ok
150 ok
...
2900 ok
2950 ok
3000 ok
done :°

And if you open the file named results_linkedin_post_likers_lobstrio.txt, located in the same folder as the script, you get a superb dataset.

We did extract LinkedIn Post Likers exhaustively, with 3000 reactions collected. And for each reaction, all the attributes mentioned initially.

Structured, exhaustive, and directly usable.

Is it possible to get email LinkedIn Users scraped through Post Reactions?

Emails are highly requested. You can deploy a successful lead generation through direct outreach strategy. And massively boost B2B sales.

Unfortunately it is not possible to recover the email address of a LinkedIn profile, from the information retrieved with this LinkedIn Post Likers scraper.

Many chrome extensions that let you find phone numbers or email addresses from a LinkedIn profile.

1. Kaspr
2. Lusha

But these do not allow mass enrichment from profile URLs. You need to click from the add-on, directly from the LinkedIn page.

Not ideal for 3000+ reactions CSV file list.

There are also mass enrichment tools, such as B2B SaaS:

1. Hunter.io
2. Dropcontact

But here, on top of the name, you need to provide the company name the person is working in. And we do not collect this information.

If you feel this specific need, please, tell us: Ideas | Lobstr.

Is it possible to scrape LinkedIn post comments with Python?

Yes, absolutely! Contact us directly via chat if you are interested in this tutorial. We will be happy to provide the complete code as well as a tutorial.

Can LinkedIn block my account?

Yes, as stated in the general conditions, if LinkedIn recognizes that you are carrying out actions in an automated manner, the account can be blocked.

And it happens quite often 🌝

Be careful not to visit pages with supernatural frequency:

1. Pause between queries
2. No more than 30K reactions collected per day
3. Secondary account usage
