Scraping Instagram Data with Instagram Scraper and Python: A Comprehensive Guide

Instagram is a rich source of data for businesses and marketers looking to better understand their audience, track trends, and analyze engagement metrics. Scraping Instagram data ethically and efficiently can provide insights into user behavior and inform your digital strategies. In this guide, we’ll walk you through the process of scraping Instagram using the instaloader Python library, and cover advanced techniques such as scraping stories and highlights, storing data, analyzing it, and even mitigating scraping challenges with proxies and VPNs.

Prerequisites

Before we dive into the code, make sure you have the following installed:

1. Python: Version 3.x or later.

2. Instaloader: A tool that downloads images, videos, and metadata from Instagram:

   pip install instaloader

3. Requests and BeautifulSoup: For additional requests and HTML parsing, if needed:

   pip install requests beautifulsoup4

Basic Profile Scraping

We’ll start by scraping basic profile data, including follower counts, captions, and hashtags:

import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load a profile by its username
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Display profile metadata
print(f"Profile: {profile.username}")
print(f"Full Name: {profile.full_name}")
print(f"Followers: {profile.followers}")
print(f"Following: {profile.followees}")
print(f"Biography: {profile.biography}")

# Download all posts
for post in profile.get_posts():
    loader.download_post(post, target=profile.username)

This basic script downloads posts from a user’s profile and provides metadata like follower counts, biography, and captions. But now, let’s take it to the next level.

Storing Scraped Data

Storing data effectively is crucial for conducting further analysis or building a dataset for machine learning models. We can store the scraped data in a structured format such as a CSV or JSON file.

Storing Data in CSV Format

Here’s how you can store scraped post data in a CSV file:

import csv
import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Open CSV file to store data
with open('instagram_data.csv', mode='w', newline='', encoding='utf-8') as file:
    writer = csv.writer(file)
    writer.writerow(['Post Date', 'Caption', 'Likes', 'Comments', 'Hashtags'])

    # Scrape posts and write to CSV
    for post in profile.get_posts():
        writer.writerow([post.date, post.caption, post.likes, post.comments, post.caption_hashtags])

This script saves essential post data into a CSV file, which you can then use for analysis or reporting.

Storing Data in JSON Format

Alternatively, you can store the data in JSON format, which is easier for developers to work with, especially if you want to feed it into web services or APIs.

import json
import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Scrape data and store in JSON
posts_data = []
for post in profile.get_posts():
    post_info = {
        'post_date': post.date.isoformat(),
        'caption': post.caption,
        'likes': post.likes,
        'comments': post.comments,
        'hashtags': post.caption_hashtags
    }
    posts_data.append(post_info)

# Write to JSON file
with open('instagram_data.json', 'w') as json_file:
    json.dump(posts_data, json_file, indent=4)

Advanced Scraping Techniques

Beyond scraping standard profile information and posts, instaloader allows you to scrape more advanced data such as stories, highlights, and follower/following lists.

Scraping Instagram Stories

Instagram stories provide valuable insights into real-time content and user engagement. Here’s how you can scrape stories:

import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Download stories if available
loader.download_stories(userids=[profile.userid])

This code will download all available stories from the specified user. You can customize it further to scrape stories from multiple users.

Scraping Instagram Highlights

Highlights are curated sets of stories saved on profiles. You can also scrape these using instaloader:

import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Download highlights
for highlight in loader.get_highlights(profile):
    loader.download_highlight(highlight)

Data Analysis

Once you’ve scraped and stored the data, analyzing it can provide useful insights, such as identifying trends in hashtag usage, understanding engagement metrics, or even conducting sentiment analysis on captions.

Sentiment Analysis

You can use the textblob library to perform basic sentiment analysis on Instagram captions:

from textblob import TextBlob
import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Perform sentiment analysis on post captions
for post in profile.get_posts():
    caption = post.caption
    if caption:
        analysis = TextBlob(caption)
        print(f"Post Date: {post.date}")
        print(f"Caption: {caption}")
        print(f"Sentiment: {analysis.sentiment}")
        print("n")

This script uses TextBlob to evaluate the sentiment of Instagram captions, providing you with a simple sentiment score based on positive or negative language.

Engagement Rate Analysis

You can calculate the engagement rate (likes + comments / followers) for posts to identify high-performing content:

import instaloader

# Create an instance of Instaloader
loader = instaloader.Instaloader()

# Load the profile
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

# Calculate engagement rates
for post in profile.get_posts():
    engagement_rate = (post.likes + post.comments) / profile.followers
    print(f"Post Date: {post.date}")
    print(f"Engagement Rate: {engagement_rate * 100:.2f}%")
    print("n")

This provides a better understanding of how well content is performing relative to the audience size.

Ethical Scraping and Legal Considerations

Before you proceed with Instagram scraping, it’s important to understand the legal and ethical guidelines that govern scraping activities:

1. Instagram’s Terms of Use: Instagram does not allow scraping of private data or the use of automated means to collect information without permission. Always scrape public data and stay within Instagram’s API usage policies.

2. Avoiding Abuse: Do not scrape data in bulk or use the scraped data for malicious purposes like spamming or unauthorized access.

3. Rate Limiting: Instagram imposes rate limits to prevent bots from overwhelming their servers. Be sure to handle rate limits responsibly by using delays between requests.

Using Proxies and VPNs for Scraping

To avoid being blocked or rate-limited, you can use proxies or VPNs to distribute requests across different IP addresses.

Setting Up a Proxy

You can set up a proxy for instaloader like this:

import instaloader

# Create an instance of Instaloader with proxy support
loader = instaloader.Instaloader()

# Add proxy settings
loader.context.session.proxies = {'https': 'https://your-proxy-address:port'}

# Now scrape as usual
profile = instaloader.Profile.from_username(loader.context, 'instagram_username')

Using proxies can help distribute your scraping activities, but be sure to use trusted and legal proxy services.

Using VPNs

If you’re doing more extensive scraping, using a VPN can help distribute traffic across different regions and IP addresses, reducing the chance of getting blocked by Instagram.

Conclusion

Instagram scraping using Python and instaloader opens up a world of possibilities for analyzing trends, engagement, and audience behavior. In this article, we covered everything from basic profile scraping to advanced techniques like scraping stories, highlights, and performing sentiment analysis. Always ensure you’re following ethical guidelines and legal considerations when scraping social media data.
