Monitor Reddit comments for keywords

Monitoring Reddit comments for specific keywords involves setting up a process to continuously scan comments on Reddit posts and identify when particular words or phrases appear. This can be useful for tracking trends, brand mentions, or specific topics of interest.

Here’s a concise guide on how to monitor Reddit comments for keywords:

1. Using Reddit API (PRAW – Python Reddit API Wrapper)

Step-by-step:

• Create a Reddit app: Go to Reddit apps, create a script app to get client_id, client_secret, and user_agent.

• Install PRAW:

bash
CopyEdit
pip install praw

• Sample Python Script:

python
CopyEdit
import praw

# Initialize Reddit instance
reddit = praw.Reddit(
    client_id='YOUR_CLIENT_ID',
    client_secret='YOUR_CLIENT_SECRET',
    user_agent='YOUR_USER_AGENT'
)

# Keywords to monitor
keywords = ['keyword1', 'keyword2', 'keyword3']

# Subreddit to monitor (e.g., 'all' for all subreddits)
subreddit = reddit.subreddit('all')

# Stream comments
for comment in subreddit.stream.comments(skip_existing=True):
    comment_body = comment.body.lower()
    if any(keyword.lower() in comment_body for keyword in keywords):
        print(f"Keyword found in comment by {comment.author}: {comment.body}")

• This script will listen to live comments and print those containing your keywords.

2. Using Pushshift API (Historical Comments)

Pushshift allows querying historical Reddit comments for keywords.

Example using requests:

python
CopyEdit
import requests

keywords = ['keyword1', 'keyword2']
query = ' OR '.join(keywords)
url = f"https://api.pushshift.io/reddit/comment/search/?q={query}&size=100"

response = requests.get(url)
data = response.json()

for comment in data['data']:
    print(comment['body'])
