Best Reddit SEO Tools (2026): Mentionova $99, Reddit Pro Free + 5

The best Reddit SEO tool for AI search is Mentionova, at $99 a month billed annually: pick it if you want the Reddit threads ChatGPT, Perplexity and Google AI actually cite for your category, ranked, with a reply drafted in your voice for a person to post. Pick Reddit Pro if you want free keyword tracking straight from Reddit, Syften or Octolens if you need fast mention alerts in Slack, and skip paid tools if a handful of free F5Bot alerts covers you. Every price and feature below comes from the vendor’s own site, captured October 31, 2026.

How did we pick these Reddit SEO tools?

Reddit SEO used to mean ranking a thread in Google. It now also means getting quoted inside AI answers, because the engines lean on the same threads. Ahrefs’ own AI Overviews page says AI Overviews lean on Reddit, Quora and YouTube, and Octolens’ Reddit page says Reddit threads rank on Google and get cited by AI assistants. A tool made this list if its own site shows it does at least one of three jobs: finds the threads that matter, alerts you when a new one appears, or helps you reply well.

1. Official pages only. Every price, limit and feature comes from the vendor’s pricing, product or help page, captured October 31, 2026. No review sites, coupon sites or affiliate roundups.
2. AI citations first. Knowing which threads AI answers quote is the scarce part, so tools that tie threads to engines ranked above tools that only alert on keywords.
3. Help with the reply. Finding a thread is half the job. We weighted tools that draft or guide the reply and keep a person in charge of posting.
4. Coverage of comments. Most buying questions sit in comments, so we noted which tools cover comments as well as posts.
5. Free path. We noted every free plan and free trial the vendor lists.

The ranking is editorial. For the wider category, see the best AI visibility tools and AI citation tracking tools. For the numbers behind Reddit’s role, see our Reddit statistics.

Mentionova

Mentionova is an AI visibility platform built around agents. Its Reddit SEO product ranks the Reddit threads that ChatGPT, Perplexity and Google AI cite for your category, then drafts a reply in your voice that answers first and discloses who you are.

Best for

Brands and agencies that want Reddit work tied to AI answers: which threads the engines quote for your buying questions, and a ready reply for each one.

How it handles Reddit

Instead of a keyword feed, you get a queue of threads ranked by influence, which Mentionova defines as how often the engines cite the thread for your prompts. Each thread shows which engines cite it. The Reddit tab lists the threads your engines cite plus threads found through Reddit search.

Replies are drafted in your brand voice with the answer first. The editor scores each draft as you work, with a humanity score, marketing words, em dashes and word count, so you can fix it before approval. Every reply moves from draft to approved to posted, or gets skipped, and a person posts it from their own account. Once posted, the thread’s citations show up beside the other engines, so you can see whether the answer starts quoting it.

What each plan includes

Source: mentionova.com/pricing, fetched October 31, 2026.

Reddit Engagement is listed on every plan, including Starter. The six engines on Scale and Enterprise are ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews and Reddit; Starter covers ChatGPT, Perplexity and Google. Every paid plan starts with a free trial with no card.

Limits

Mentionova never posts to Reddit, by design, so someone on your team still has to post and reply to follow-ups. It is not a real-time alert tool for every brand mention; it focuses on the threads that matter to AI answers and Reddit search.

The pricing catch

Enriching a thread (pulling its upvotes and comment count, then drafting the reply) costs 5 tasks from the plan’s pool, which grids and workflows share. If every Starter task went to Reddit, that is 20 threads a month, or about $4.95 a thread. Scale works out to about $3.20 a thread and Enterprise about $1.60. Re-opening a thread you have already enriched is free.

Who should skip it

Skip it if you only want an inbox of every mention of your brand name, or if nobody on your team will post replies. A monitoring tool such as Syften or the free Reddit Pro is a better fit for pure alerts.

Why it is #1

It is the only tool here that starts from the threads AI answers cite for your own prompts, and the only one that drafts the reply and then tracks the citation after you post. See the Mentionova review for the rest of the platform.

Reddit Pro

Reddit Pro is Reddit’s own free toolkit for businesses. It covers a business profile, keyword monitoring through Trends, and performance metrics for your posts and comments.

Best for

Any brand starting on Reddit that wants official data and a business profile at no cost.

How it handles Reddit

Trends, launched January 7, 2025, lets you track keywords such as your brand, products and competitors and see where, when and how they are discussed. For each keyword it shows the most discussed posts and comments and the communities talking about it. Smart keywords add conversation volume, related keywords and an AI-generated summary of top discussions organised into themes; smart keywords are only available for some brand names, products, categories and topics so far. Reddit’s help center says there is currently no limit to the number of keywords you can track in Trends.

Profile tools let you pick an AI-generated bio at sign-up and repost conversations about your business from Trends to your profile. Reddit Pro also measures post and comment performance, from upvote rate to views.

What it costs

Free. Reddit’s page says “Sign-up for Reddit Pro (it’s free)”.

Limits

Trends is a dashboard, not an alert stream to Slack or email, and it does not tell you which threads AI answers cite. Standard keywords get only posts, comments and communities; the richer insights depend on smart keyword coverage.

The pricing catch

None on price. The cost is time: someone has to check Trends and decide which threads to answer.

Who should skip it

Teams that need alerts pushed to Slack within minutes, or that need to know which threads ChatGPT and Perplexity quote.

Ahrefs Brand Radar

Brand Radar is Ahrefs’ AI visibility product. Its AI Sources section lets you search across Reddit results in Google, including titles, descriptions and subreddit snippets, next to YouTube and TikTok.

Best for

SEO teams already on Ahrefs that want Reddit results in Google alongside a large AI prompt index.

How it handles Reddit

You search Reddit results that appear in Google by keyword and see the threads, titles and subreddits. The AI Visibility Index maps visibility across 519 million prompts people ask AI platforms. YouTube, TikTok and Reddit are listed as a bonus for Ahrefs customers, free while in beta.

What each plan includes

Source: ahrefs.com/brand-radar and ahrefs.com/pricing, fetched October 31, 2026.

Limits

It does not send live mention alerts, rank threads by how often AI cites them, or draft replies. The Reddit search covers Reddit results in Google, not every post and comment on Reddit.

The pricing catch

The Reddit, YouTube and TikTok search is a bonus for Ahrefs customers while in beta, so the cheapest path still runs through an Ahrefs subscription plus Brand Radar. See Ahrefs pricing for the base plans.

Who should skip it

Teams that are not on Ahrefs, and anyone who mainly needs to reply to threads rather than research them.

Writesonic

Writesonic is an AI visibility and content platform. Its home page says 85% of AI citations come from sites you don’t own and that it surfaces every Reddit thread, YouTube video and high-DR listicle citing competitors, then drafts the outreach.

Best for

Teams already buying Writesonic’s Growth plan or Enterprise that want Reddit threads flagged inside a wider off-page workflow.

How it handles Reddit

The Reddit work runs through the Action Center, which Writesonic labels with a Reddit Agent and an Outreach Agent. It finds threads that cite competitors and drafts outreach, alongside on-page fixes.

What each plan includes

Source: writesonic.com/pricing, fetched October 31, 2026.

Limits

On Starter and Basic the pricing page lists Action Center as available on Enterprise, so the Reddit features are not part of the lower tiers.

The pricing catch

Growth’s Action Center is a trial capped at 5 off-page actions a month. A full Action Center means Enterprise at a custom price.

Who should skip it

Anyone who wants Reddit help under $399 a month, or a dedicated Reddit reply workflow.

Octolens

Octolens is a brand mention monitoring tool that tracks Reddit posts and comments, with AI filtering, and pushes mentions to Slack, email, webhooks or an API.

Best for

Teams that want fast, filtered Reddit mentions in the tools they already use.

How it handles Reddit

You add keywords and subreddits, and Octolens can track whole subreddits alongside keywords. It monitors comments as well as posts and surfaces new mentions within 1 to 2 minutes. MCP, API and webhooks are on all plans, with unlimited seats.

What each plan includes

Source: octolens.com/pricing, fetched October 31, 2026.

Extra keywords cost $10 each on Pro and $5 on Scale. Pro keeps 2 years of history and Scale unlimited history; Scale adds podcasts, news from 150k+ outlets and the web. There is a 7-day trial with no card and up to 5,000 mentions.

Limits

It reports mentions, not which threads AI answers cite, and it does not draft replies.

The pricing catch

Overage is $0.013 per mention on Pro and $0.01 on Scale, so 5,000 extra mentions on Pro adds about $65. The headline prices are billed annually.

Who should skip it

Small teams with one brand and a few keywords, where Syften or F5Bot cost far less.

Syften

Syften is a keyword monitoring tool for Reddit and other communities. It targets Reddit delivery in under one minute and routes matches to email, Slack, RSS, API or webhooks.

Best for

Founders and small teams who want precise, cheap alerts for recommendation requests and competitor mentions.

How it handles Reddit

Filters cover posts and comments and can be narrowed by subreddit, author, title and type, with an optional AI relevance rule to cut noise. Syften says it scanned 400,822,882 Reddit posts and comments in the last 30 days.

What each plan includes

Source: syften.com, fetched October 31, 2026.

X costs +$40/mo and YouTube +$20/mo on top. The PRO plan has a 14-day free trial with no card, and you see matching mentions from the last 60 days straight away.

Limits

Entry keeps a 7-day archive and has no Slack. Syften does not rank threads by AI citations or draft replies.

The pricing catch

Slack and AI filtering start on Standard, not Entry. Standard with X and YouTube added comes to $109.95 a month.

Who should skip it

Teams that want analytics, dashboards or AI citation data rather than an alert stream.

F5Bot

F5Bot sends keyword alerts from Reddit, Hacker News and Lobsters. It has run since 2017 and says it delivers more than 430,000 alerts a day.

Best for

Individuals and tiny teams who want free email alerts for a few keywords.

How it handles Reddit

You enter brand names, products or topics, and F5Bot emails you when they appear. Paid tiers speed up alerts, add RSS and JSON feeds and, on Gold, Slack or Discord and AI filtering.

What each plan includes

Source: f5bot.com/tiers, fetched October 31, 2026. Diamond starts at $500/mo.

Limits

The free tier is for personal use only, keeps 7 days of history and caps alerts at 20 a day. Silver is non-commercial too. There is no AI citation data and no reply help.

The pricing catch

Commercial use starts on Gold, at $49.99 a month or $549 a year, which saves about $50.88 against paying monthly. AI filtering includes the first $10 a month of token usage.

Who should skip it

Businesses that need commercial use on a budget, where Syften Entry costs less than F5Bot Gold.

How to choose a Reddit SEO tool

Start from the threads AI cites

Ask the questions your buyers ask in ChatGPT, Perplexity and Google, and note the Reddit threads in the sources. Those threads are worth more than any new mention, because the answer already quotes them. Mentionova does this per prompt; Ahrefs Brand Radar helps with the Google side.

Decide whether you need alerts or a queue

Alert tools (Syften, Octolens, F5Bot) are built for speed: a complaint or a “what should I use?” post lands in Slack within minutes. A ranked queue (Mentionova) is built for impact: fewer threads, chosen because the engines cite them.

Check comment coverage

Octolens and Syften both cover comments, where many buying questions sit. Reddit Pro Trends shows posts and comments for each keyword.

Keep a person on the post button

Every tool here leaves posting to you, and that is the right default. Reddit communities set their own rules on vendor replies, and a disclosed, useful answer is the one that survives.

How to start on Reddit this week

1. List 10 buying questions and run them in ChatGPT, Perplexity and Google. Note every Reddit thread cited.
2. Sign up for Reddit Pro under a business username and add your brand, product and top competitor as Trends keywords.
3. Rank the cited threads by engagement and by how many engines cite them. Mentionova does this for you; by hand, a spreadsheet works.
4. Draft one reply per thread that answers the question first and discloses who you are. Leave links out of the first reply.
5. Set an alert for new recommendation requests in Syften, Octolens or F5Bot, so you see the next thread while it is fresh.
6. Re-check the answers in 30 days to see whether the threads you answered now show up with your brand.

Reddit is one source among several. Our YouTube statistics and Wikipedia statistics cover the other community sources AI answers lean on, and LLM brand monitoring tools covers tracking your brand across the answers themselves.

Which should you choose?

Choose Mentionova if Reddit matters because AI answers quote it: it finds the cited threads for your prompts, drafts the reply and shows the citation afterwards, from $99 a month billed annually. Choose Reddit Pro as the free first step for every brand. Add Syften or Octolens if you need mentions in Slack within minutes, and Ahrefs Brand Radar if you already pay for Ahrefs. Skip Writesonic for Reddit alone unless you are on its Growth plan or Enterprise, and keep F5Bot for personal or very small projects.

Frequently asked questions

What is Reddit SEO?

Reddit SEO is the work of getting your brand into the Reddit threads that Google ranks and that AI answers cite, then keeping those threads accurate. In practice it means finding the threads buyers read, answering them helpfully from a disclosed account, and tracking whether the engines quote them. It is not posting links or buying upvotes, which most subreddits remove.

What is the best Reddit SEO tool?

Mentionova, for teams whose goal is showing up in AI answers. It ranks the Reddit threads ChatGPT, Perplexity and Google AI cite for your category, drafts a reply in your voice and leaves the posting to a person. It starts at $99 a month billed annually, and Reddit Engagement is on every paid plan. If you only need free keyword monitoring, start with Reddit Pro.

Is there a free Reddit SEO tool?

Yes. Reddit Pro is Reddit's own business toolkit and is free. Its Trends tool tracks keywords with no stated limit, shows the posts, comments and communities that mention them, and adds AI summaries for some keywords. F5Bot also has a free tier with 5 keywords, alerts up to 2 hours late and 7 days of history, for personal use only.

Does Mentionova post to Reddit for me?

No. Mentionova drafts the reply and scores it, but a person on your team adds any disclosure the subreddit expects and posts from their own account. Each reply moves from draft to approved to posted, or gets skipped. Mentionova says it never posts to Reddit.

Which Reddit threads do AI answers cite?

The ones that already rank and get engagement for the question a buyer asks. No vendor publishes a universal list, so the useful step is checking your own prompts. Mentionova shows which engines cite each thread for your prompts, and Ahrefs Brand Radar lets you search Reddit results in Google by title, description and subreddit.

How much do Reddit monitoring tools cost?

From free to about $500 a month on the official pages we checked. Reddit Pro is free, F5Bot Silver is $12.99 a month, Syften Entry is $29.95 a month, F5Bot Gold is $49.99, Octolens Pro is $159 a month billed annually and Octolens Scale is $499 billed annually. These tools alert you to mentions; they do not show which threads AI answers cite.

Should a brand reply on Reddit as itself?

Usually yes, and disclosed. Reddit Pro is built for business profiles and suggests a new username for your business rather than your personal account. Mentionova's drafts answer first and mention the brand last with a disclosure line. Check each subreddit's rules before you post, because many restrict vendor replies.

Can I track Reddit inside Ahrefs?

Partly. Ahrefs Brand Radar can search Reddit results in Google, including titles, descriptions and subreddit snippets, and lists YouTube, TikTok and Reddit as a bonus for Ahrefs customers that is free while in beta. Brand Radar's AI Visibility Index costs $199 a month. It does not send live alerts or draft replies.

Does Writesonic help with Reddit?

Writesonic says it surfaces Reddit threads, YouTube videos and high-DR listicles that cite competitors and drafts outreach. That work sits in its Action Center, which is only a trial on Growth ($399 a month billed annually, 5 off-page and 5 on-page actions a month) and is full on Enterprise. Starter and Basic do not include it.

How fast do Reddit alerts arrive?

Syften targets Reddit delivery in under one minute. Octolens surfaces new mentions within 1 to 2 minutes and covers comments. F5Bot's free tier can be up to 2 hours late, Silver is within 5 minutes and Gold is instant. Speed matters most for complaints and recommendation requests, where the first useful reply tends to win.
