How to Monitor Keywords on X and Reddit to Find Leads

This article is part of our comprehensive SaaS Growth Strategies Guide.

How to track Reddit mentions and get alerts automatically

Yes, you can automate it. Pick your keywords (your product name, competitor names, and the problem phrases buyers use), then point a Reddit listening tool at them: F5Bot emails you within minutes when a term appears, and Syften and Octolens add Slack alerts and AI filtering. If you want the alert to also tell you whether the person is a buyer and hand you a reply to send, OneUp Today's Lead Agent watches your subreddits 24/7, scores every post 0 to 100 for buying intent, and drafts the DM or reply for you to approve.

1. Write three keyword groups: your brand, your competitors, and the problem in the buyer's own words ("looking for a tool that...").
2. Choose where alerts land: email for a daily sweep, Slack if you want to reply within the hour.
3. Filter before you read: raw keyword matches are mostly noise, so use AI filtering or intent scoring to cut the list.
4. Reply while the thread is active: lead with help, and mention your product only where it answers the question.

What is Social Listening for Leads?

Social listening means monitoring social platforms for conversations relevant to your business. For lead generation, you're looking for people actively discussing problems your product solves.

OneUp Today Social Listening automates exactly this: it watches X and Reddit for high-intent mentions, scores buyer intent, and drafts the reply or DM you approve, so a mention becomes a conversation instead of a data point.

Unlike traditional marketing where you push messages out, social listening is about finding people already expressing need and engaging with them directly.

Why Is Social Listening So Effective for Leads?

• High intent: People actively asking for solutions
• Perfect timing: Catch them when the problem is top of mind
• Low cost: No ad spend required
• Relationship building: Start with help, not pitch

Setting Up Monitoring

For X (Twitter)

Native Search

Use advanced search operators:

• Keywords: "looking for [product type]"
• Exclusions: -filter:retweets -is:retweet
• Sentiment: "frustrated with" OR "hate how"
• Questions: "what do you use for" OR "recommend"

Example Searches

• "social media scheduler" recommend -is:retweet
• "alternative to Buffer" OR "Buffer alternative"
• "looking for" "content calendar" min_replies:1

For Reddit

Subreddit-Specific Searches

Monitor specific subreddits where your audience lives:

• site:reddit.com/r/SaaS "recommendation"
• site:reddit.com/r/startups "looking for"
• site:reddit.com/r/Entrepreneur "tool for"

Keywords to Monitor

• Recommendation requests
• Competitor mentions
• Problem descriptions matching your solution
• Pricing complaints about alternatives

High-Intent Keywords by Category

Research Phase

• "best [product category] for"
• "[product category] comparison"
• "reviews of [competitor]"
• "anyone used [competitor]"

Purchase Phase

• "looking for [product category]"
• "need a [product category]"
• "recommend a [product category]"
• "suggestion for [product category]"

Switching Phase

• "alternative to [competitor]"
• "leaving [competitor]"
• "switching from [competitor]"
• "[competitor] is too expensive"

Engaging Without Being Spammy

Done right, this beats paid ads on response. In our study of 2,269 Reddit DMs, personalized outreach to people who described a problem replied at 29.7%, roughly 5x cold email's typical 1 to 5%. The catch: that number only holds when you lead with help, not a link.

The 80/20 Rule

• 80% of your engagement should be purely helpful
• 20% can mention your product (when relevant)

Good Engagement

• Answer the question completely
• Share your personal experience
• Mention your product only if directly relevant
• Be honest about your affiliation

Bad Engagement

• Drop a link without context
• Copy-paste the same response
• Pitch to everyone mentioning a keyword
• Hide that you're affiliated with the product

Automating the Process

What to Automate

• Monitoring: Keyword alerts across platforms
• Filtering: AI to identify high-intent posts
• Alerting: Notifications when opportunities arise
• Drafting: AI-generated response suggestions

What to Keep Manual

• Sending: Review before responding
• Customization: Make each response unique
• Judgment: Decide when to engage

Measuring Success

Track These Metrics

• Posts found per day: Is monitoring comprehensive?
• Response rate: How many engage back?
• Click-through rate: Do they visit your site?
• Conversion rate: Engagement to signup to paid

Iterate Based on Data

• Which keywords produce best leads?
• Which platforms convert better?
• What response style gets engagement?
