If you’re like me, when you want to find out what real people are saying about a product or app, you go to Google search and type in your question … then add “Reddit” to the end.
People all around the world modify their searches like this every day, as Reddit is considered by many to be a trusted and accurate source; even more so than traditional search engine results pages (SERPs) or ChatGPT.
And because so many people want to see information provided by Reddit users, it’s becoming increasingly important for brands to actively work on their Reddit marketing strategy. By doing so, you can both ensure your company comes up in “Reddit”-modified search results and potentially nab multiple spots in a SERP: your website and a related subreddit.
Estimate traffic you could steal from competitors
Because Reddit is a predominantly text-driven platform, you‘ll want to approach Reddit search engine optimization (SEO) from a keyword-based perspective. For your efforts to work, you’ll need to know:
While you can use a standard keyword research tool like Semrush and some manual digging to find all of this information out, there are a growing number of Reddit SEO tools that‘ll make your work easier.
A good Reddit SEO tool should include:
Tip: Combining a Reddit SEO tool and a trend spotting platform can give you the best results.
Our new Reddit SEO tool is completely free and gives you a helpful overview of:
My favorite thing about the Reddit tool, though, is how it shows you multiple subreddits that you could leverage for your brand.
This information makes it easy to plan exactly how you could start using Reddit to provide support to your customers, showcase new product features, and drive organic traffic to your website.
Our Reddit SEO tool even tells you the best times to post on Reddit and provides sample comments you could use to start a conversation around your brand.
2. Exploding Topics Pro: Best Paid Reddit SEO Tool
Exploding Topics is also incredibly valuable when used for Reddit SEO.
If you subscribe to Exploding Topics Pro, you can use our social listening data to:
Exploding Topics’ data is extremely important, because it lets you determine if a trending topic is actually popular on Reddit or not. Without this information, you might waste your time trying to generate conversations on Reddit about topics that are only popular on Instagram or LinkedIn.
If you need Reddit data, Google SERP information, paid advertising tools, and more, then you’ll want an all-in-one research and keyword tracking tool like Semrush One.
With a Semrush account, you can:
You can use a free Semrush account to do a limited amount of keyword discovery and competitor research, but I recommend upgrading to a paid plan if you’re serious about improving your Reddit SEO. I use Semrush every day for different tasks related to my marketing work — it’s an incredibly versatile and useful platform.
Tip: Exploding Topics Pro is actually an app that works inside of Semrush, so you can get the best of both worlds all in one spot — just sign up for a Semrush account and then add on an Exploding Topics free trial to see how the two tools work together.
Use trending keywords to create content your audience craves.
Keywordly is an AI-powered content creation tool for organic marketing. It includes a feature that analyzes topics and conversations across both Quora and Reddit, making it a great choice for anyone who wants to get ideas from — or optimize for — multiple forums at once.
With Keywordly, you can:
While Keywordly does offer users a variety of free tools, the Reddit and Quora keyword research tool is not one of them — you’ll need to subscribe to a paid plan for access to this feature.
Important: Keywordly will show you how different conversations relate back to your keyword of choice. If you want to see how other keywords, in the form of trends, connect to each other, then you’ll want to use something like the Exploding Topics Meta Trends reports. Personally, I’d start my research with Exploding Topics, identify connected trends, then use Keywordly to search for conversations about those topics.
Higher Visibility's Keyworddit tool lets you see specific topics and terms associated with a single subreddit.
For example, if I search r/3dprinting using Keyworddit, I can see that the users of this subreddit frequently talk about:
Each result includes monthly search volume related to the term and a link to a Google search page for that topic and subreddit.
Keyworddit is free to use and can be a useful step in your research process, especially after you’ve used our Reddit SEO tool to identify specific subreddits that are related to your brand.
It’s important to note, though, that not all subreddits are available for analysis and not-safe-for-work (NSFW) topics are included in the lists of suggested subreddits. However, if a subreddit you’re interested in is part of Keyworddit results, the tool is very useful.
Calculate potential organic traffic for a target keyword based on Google ranking positions
This free Mangools Reddit thread suggestions tool works similarly to Keywordly, but is only focused on Reddit — not Quora.
Mangools gives you some additional data that Keywordly doesn’t, too, including:
Because Mangools offers this tool for free, it’s a great option to use when you’re first starting out — and it’s worth checking Mangools’ results in addition to the data you get from a paid tool like Keywordly, too.
Sprout Social offers social listening tools that you can use to monitor and analyze the sentiment behind various Reddit conversations. This tool is useful if you are tackling a massive Reddit optimization campaign for a large brand — the sort of operation that would require days if not weeks of your time to collect and analyze data manually.
When using Sprout Social to analyze trending discussions, you can see information that includes:
You can also use the tool to identify influencers who may be able to further amplify your brand and boost user engagement online.
Sprout Social isn't a free tool, though, and its other features could wind up duplicating functionality that you already pay for through another social media management tool. Be sure to consider carefully whether you’ll benefit more from Sprout Social or an all-in-one platform like Semrush One (and yes, you can do social media management through Semrush).
I regularly consider Reddit in my SEO and generative engine optimization (GEO) work, as it’s an important part of targeting both people and AI search tools. Here’s the exact tech stack and process I recommend for mastering your Reddit SEO this year:
You can try all of these steps right now for free. Just grab your 14-day extended free Semrush trial, then add on a 7-day free trial of Exploding Topics Pro. I’m confident that you’ll be impressed by both the data accuracy and breadth available to you — and will be relieved to see just how easy mastering Reddit optimization really is.
