Do you really track every Reddit comment live?

Yes, as a specialized Reddit keyword tracker we aim for at most a 1-minute delay. And because we specialize in live content delivery (as opposed to searching historical data) we're able to perform a more advanced search that is not possible for search engines.

You can get your results delivered through our Slack integration, email, RSS or an API.

So what can a Reddit monitoring tool be used for?

You can use Syften to receive alerts whenever a thread is started or a comment is posted with the keywords you want to monitor. This allows you to be one of the first to comment or find discussions that are relevant to you or your business.

By replying you're not only helping the original poster, but also the army of lurkers. The thread will be indexed by Google, and people searching for similar questions in the future will find your reply.

You can also monitor the activities of other users, see their posts and track their paid ads (a Reddit paid ad is just a post).

And if someone posts a link to your article your team can give it that initial upvote and comment needed to reach the top.

Reddit social listening? Sounds like it could get me banned

We’ve all seen plenty of these:

Four days and no upvotes? Why even bother?

Four days and no upvotes? Why even bother?

Ouch, wouldn't want that.

Ouch, wouldn't want that.

Can we turn that into this?

That's more like it.

You could get banned, if your posts are obnoxious. Once you sign up you'll receive a few guides that explain how not to be. At Syften, we can track 16% of our customers to social listening. It's easier than you think.

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.

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.

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.

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.

That could be you! So let's get started!
