IGBot: AI-Powered Instagram Marketing Automation

The Challenge

Instagram marketing is time-consuming and often ineffective when using generic, mass-produced messages. Businesses struggle to reach their target audience with personalized content at scale. I set out to solve this problem by building an intelligent automation tool that combines profile scraping with AI-generated personalized messaging.

Project Overview

IGBot is an automated Instagram marketing tool that revolutionizes how businesses engage with potential customers on Instagram. By leveraging OpenAI's language models and intelligent profile scraping, the bot delivers personalized messages that feel authentic and relevant to each recipient.

Key Results

• 25% increase in engagement - Personalized messages significantly improved response rates
• 500+ targeted DMs per week - Automated outreach at scale without sacrificing quality
• Improved product visibility - Reached highly targeted audiences based on specific keywords
• Time savings - Reduced manual outreach time by 90%

Technical Architecture

Profile Scraping System

The first component is an intelligent profile scraper that identifies potential customers based on specific keywords and criteria:

# Instagram Profile Scraper
import instaloader
from typing import List, Dict

class ProfileScraper:
    def __init__(self, keywords: List[str]):
        self.loader = instaloader.Instaloader()
        self.keywords = keywords
        self.target_profiles = []
    
    def scrape_by_hashtag(self, hashtag: str, max_posts: int = 100):
        """Scrape profiles from posts with specific hashtags"""
        posts = self.loader.get_hashtag_posts(hashtag)
        
        for post in itertools.islice(posts, max_posts):
            profile = {
                'username': post.owner_username,
                'profile_id': post.owner_id,
                'bio': self.get_profile_bio(post.owner_username),
                'follower_count': post.owner_profile.followers,
                'engagement_rate': self.calculate_engagement(post)
            }
            
            # Filter based on criteria
            if self.is_target_profile(profile):
                self.target_profiles.append(profile)
        
        return self.target_profiles
    
    def is_target_profile(self, profile: Dict) -> bool:
        """Determine if profile matches target criteria"""
        # Check if bio contains relevant keywords
        bio_match = any(keyword.lower() in profile['bio'].lower() 
                       for keyword in self.keywords)
        
        # Check engagement and follower thresholds
        min_followers = 1000
        min_engagement = 0.02  # 2% engagement rate
        
        return (bio_match and 
                profile['follower_count'] >= min_followers and
                profile['engagement_rate'] >= min_engagement)
    
    def calculate_engagement(self, post) -> float:
        """Calculate engagement rate for a post"""
        total_engagement = post.likes + post.comments
        return total_engagement / post.owner_profile.followers

AI-Powered Message Generation

The core innovation is using OpenAI's GPT models to generate personalized messages based on each profile's unique characteristics:

# AI Message Generator
import openai
from typing import Dict

class MessageGenerator:
    def __init__(self, api_key: str, product_info: Dict):
        openai.api_key = api_key
        self.product_info = product_info
    
    def generate_personalized_message(self, profile: Dict) -> str:
        """Generate a personalized DM based on profile information"""
        
        prompt = f"""
        Generate a friendly, personalized Instagram DM for the following profile:

        Our product: {self.product_info['name']}
        Product description: {self.product_info['description']}
        
        Requirements:
        1. Keep it under 150 characters
        2. Reference something specific from their bio or interests
        3. Naturally introduce our product as a solution
        4. Include a clear call-to-action
        5. Sound authentic and conversational, not salesy
        6. Use emojis sparingly and appropriately
        
        Generate only the message text, no additional commentary.

        response = openai.ChatCompletion.create(
            model="gpt-4",
            messages=[

        )
        
        message = response.choices[0].message.content.strip()

        Requirements:
        1. Keep it under 100 characters
        2. Add value or ask a question
        3. Don't be pushy
        4. Reference the original message naturally
        
        Generate only the follow-up text.
        """
        
        response = openai.ChatCompletion.create(
            model="gpt-4",
            messages=[
                {"role": "system", "content": "You are an expert at writing non-pushy follow-up messages."},

Automated Messaging System

The messaging system handles rate limiting, scheduling, and tracking to ensure compliance with Instagram's policies while maximizing reach:

# Automated Messaging System

        responses = sum(1 for msg in self.sent_messages 
                       if msg.get('response_received'))
        
        response_rate = (responses / total_sent * 100) if total_sent > 0 else 0
        
        return {
            'total_sent': total_sent,
            'responses': responses,
            'response_rate': f"{response_rate:.2f}%"
        }
