What you can monitor on Reddit
Syften is built for specific Reddit alerts: brand names, product names, domains, competitors, recommendation requests, pain points, and links to your content. If someone is talking about something your team should act on, Syften can send it to you.
Brand mentions
Catch posts and comments that mention your company name, product names, domain, or common misspellings.
Competitor mentions
Watch competitor names, domains, and product phrases so you notice comparison threads and migration intent.
Recommendation threads
Find people asking for tools, alternatives, agencies, apps, and services in your category.
Pain points
Monitor phrases that signal frustration, broken workflows, missing features, and problems your product solves.
Subreddit discussions
Track all of Reddit by default, or focus filters on a subreddit when a niche community matters more than broad coverage.
Links to your content
See when Reddit users share your site, docs, blog posts, landing pages, or competitor comparison pages.
The benefits of answering questions on Reddit
The person who asked the question learns about your product
Other people reading the discussion learn about your product
You "steal" SEO from Reddit, and your comment then ranks highly for the keywords in the question
ChatGPT and Perplexity start recommending your product
Reddit keyword alert examples
These are Syften filters, not Google search queries. Start with a product name, domain, competitor, or subreddit, then add title filters, post/comment filters, exclusions, or language filters when the alert is too broad.
| Goal | Example filter | What it finds |
|---|---|---|
| Brand mentions | syften.com | Mentions of your domain, including subdomains and common obfuscated forms like syften[.]com. |
| Product name | "Yet Another Mail Merge" | Mentions of a multi-word product name. |
| Competitor mentions | yamm.com | Discussions where people mention a competitor's domain. |
| Buying intent | "alternative to" hubspot | Posts and comments where someone compares options around a known tool. |
| Subreddit-specific alert | site:reddit.com/r/saas/ type:post title:mrr | New threads in r/saas with mrr in the title. |
| Questions in a subreddit | site:reddit.com/r/shopify/ title:plugin title:`?` | Shopify subreddit threads with plugin and a question mark in the title. |
| Track a Reddit user | site:reddit.com author:someuser123 | Posts and comments by a specific Reddit user, including promoted posts (ads). |
| Noise reduction | syften NOT lang:sv | Syften mentions while excluding Swedish-language matches. |
| AI filtering | apple $accept:"true when the post mentions Apple the company; false otherwise." | Adds an AI accept/reject check before Slack or email notifications are sent. |
Syften filters are precise enough to find the Reddit comments you actually want, without flooding you with junk.
Reddit social listening vs Reddit keyword alerts
Social listening often means broad dashboards, sentiment charts, share-of-voice reports, and weekly analysis. Those are useful for some teams, but they are not the same job as catching a live Reddit thread while someone is still looking for help.
Syften is strongest when you want fast, precise Reddit keyword alerts. It finds actionable posts and comments, filters out noise, and sends the match to the person who can reply.
Why not just use Reddit search or Google Alerts?
Reddit search is useful when you remember to check it. It is not a monitoring workflow, and manual searching makes it easy to miss short-lived recommendation threads.
Google Alerts can help with broad web mentions, but it misses most Reddit comments. Syften tracks Reddit directly and reliably, including posts and comments, and sends alerts to Slack, email, RSS, API, or webhooks.
If you are still comparing options, see the guide to the best Reddit monitoring tools.

At Rewardful, we're huge believers in word-of-mouth marketing. I've used most of the social monitoring tools on the market and most have a lot of noise in the results or miss important conversations happening online. Syften returns the most relevant social mentions with the least amount of noise out of all the tools I've tested so far. Their community listening is the best on the market and I love how you can fine tune by source.
I love that Syften monitors all the communities I am part of but don't have enough time to check all day. Now, I can check my email and see conversations happening on Twitter, Reddit, Indie Hackers, and many more places. It's incredibly useful. Worth every dollar.
We use Syften to react to people saying things about us on the internet every single day. It's a set once and forget tool that just helps your team keep your pulse on whatever it is you care about.
Syften is awesome. I use it for my business so I can monitor the brand, and participate in online discussions which can help us attract new customers. I also use it personally to keep track of niche subjects that I'm interested in like emerging tech and products.
We love Syften at PostHog and find it incredibly useful for listening to our open-source community. The Slack integration enables our entire team to find ways to connect with our users, whether it's the Marketing team sharing new content or the Engineering team answering technical questions. The filtering system is especially powerful and helps us separate the signal from the noise.
I've written a couple books and like to keep an eye on how and where folks are talking about them. Syften has helped me catch several key conversations that I otherwise wouldn't have seen. Even on the days without any notable alerts, I'm still happy to know that I haven't missed anything. A very useful tool.
Syften has become integral to our business. It allows us to monitor *and* respond in real-time using their super simple webhooks. For example, when people mention our competitors being expensive on Twitter, Syften finds it and enables us to respond instantly with Zapier. It's paid for itself many times over. It even helped us secure $5M in funding for one of our community members. Michael has been overwhelmingly supportive over the past 18+ months we've been a customer and we couldn't be more grateful.
I use Syften every day and have been for a year. I looked at various other social listening tools but they were mostly aimed at big brands and enterprise customers and carried a hefty price tag. Syften tracks all of the major networks that I'm interested (even ones the big tools don't) and it's affordable for businesses of every size. Every day I get an email digest of people talking about my product for me to take immediate action on.
I gather the mentions I get from Syften and add them to our customer sales and partner presentations to show how our product is gaining mindshare amongst users on Reddit and forums. These slides are very impactful.
Syften has been a great tool to understand in which communities my website is being mentioned, or topics relevant to my business. It allowed me to engage in meaningful discussions and to identify some important actors in my niche.
Syften has enabled us to keep an eye on the topics related to our product. We can easily track posts about discount codes, email marketing, and e-commerce. We can then suggest using our service, or just be helpful answering questions on subjects that we are familiar with.

Frequently asked questions
Can I get alerts when keywords are mentioned on Reddit?
Is Reddit monitoring the same as Reddit social listening?
Not exactly. They overlap, but they are not the same job. Broad social listening tools usually emphasize dashboards, sentiment, and share-of-voice reports. Syften is closer to an alerting workflow: find the Reddit posts and comments worth reading, answering, routing, or researching.
Can Syften monitor Reddit comments, not just posts?
Yes. Syften monitors both Reddit posts and comments. The type:post filter returns new threads, and type:comment returns replies.
How do I monitor Reddit for brand mentions?
Start with your company name, product names, domain, founder names, and common misspellings. Domains are treated specially: example.com also catches subdomains and common obfuscated forms like example[.]com.
Noisy brand names can be narrowed with exclusions, language filters, subreddit filters, or AI filtering.
How do I monitor Reddit for competitor mentions?
Track competitor product names, domains, founder names, and Reddit usernames. This catches comparison threads, complaints, recommendation requests, support problems, and product-switching conversations.
Add tags when you want to route competitor alerts separately from brand alerts.
How do I get Slack alerts for Reddit keywords?
Connect Slack, choose the channel, then add the Reddit filters you want to watch. Syften sends matching Reddit posts and comments to Slack, and you can also use email, RSS, API, or webhooks.
Can Syften help my team find my Reddit comments to upvote?
Yes. Monitor your Reddit username with an author filter, tag those matches, and route that tag to a separate Slack channel. An example filter is author:yourusername $tag:upvotes, which can send your Reddit posts and comments to a channel where teammates can see them quickly.
How fast are Reddit keyword alerts delivered?
Syften's target is to deliver Reddit matches in under 1 minute. That speed matters because useful Reddit threads often get crowded fast; the value is seeing them while a helpful reply can still be noticed.
Can I monitor specific subreddits?
Yes. The site: operator can limit alerts to a subreddit, as in site:reddit.com/r/saas/. Multiple site: operators can be used together, and they are treated as alternatives.
End subreddit filters with a trailing slash so site:reddit.com/r/cat/ does not also match /r/catapult. The site operator documentation has more examples.
How do you keep Reddit alerts from getting noisy?
Start narrow: product names, domains, subreddits, post type, language, title terms, exclusions, and exact text when needed. Add $accept AI filtering in cases where keywords alone are too broad.
AI filtering works best with clear rules such as $accept:"true if the post asks about Apple laptop recommendations; false otherwise."
How is Syften different from Google Alerts?
Google Alerts can help with broad web mentions, but it misses most comments on Reddit. Syften tracks Reddit directly and reliably, including posts and comments, with filters built for community monitoring.
Google Alerts is free, so there is no reason not to use it alongside Syften as general web coverage.
Can I search older Reddit mentions after signing up?
Yes. Syften includes archive search so you can test filters and find recent Reddit mentions from before you created an alert. During the trial, Syften immediately shows you who mentioned you in the last 2 months.
Do you support other communities, or just Reddit?
Yes. Syften also monitors Hacker News, X/Twitter, YouTube, Bluesky, GitHub, Product Hunt, Stack Exchange, forums, blogs and news, selected Slack communities, Mastodon, podcasts, newsletters, and more. The documentation has the full source list.
