Google Keyword Planner vs Keyworddit in 2026: Google Ads volume data vs Reddit community language mining

Both tools are free, but they answer completely different questions. One forecasts search volume from Google's ad systems. The other extracts the vocabulary real Reddit communities use around a topic and pairs it with search volume from Grepwords.

Key takeaways
  • Both tools are completely free. Google Keyword Planner requires a Google Ads account and billing profile to access; Keyworddit requires no account at all.
  • Keyword Planner sources volume data directly from Google's own search systems. Keyworddit sources its volume data from Grepwords, which the tool itself notes is similar to Keyword Planner data but should be cross-referenced for accuracy.
  • Keyworddit extracts keywords from real Reddit comment threads within a chosen subreddit, surfacing authentic user language. Keyword Planner generates suggestions from Google's own keyword and search-term database, not from any single community's discussions.
  • Keyworddit only works on subreddits with 10,000+ subscribers; smaller communities return no results. Keyword Planner has no such restriction and works for any keyword or topic.
  • Keyword Planner includes CPC data and a performance forecasting tool for projecting clicks and impressions. Keyworddit has neither; it is a keyword-and-volume list with context links, nothing more.
  • Keyword Planner offers API access via the Google Ads API. Keyworddit has no API, no integrations, and no automation options of any kind.
  • Keyworddit has no saved projects or search history; every session starts fresh. Keyword Planner keeps keyword plans tied to your Google Ads account.

Google Keyword Planner and Keyworddit are both free, which is unusual for a keyword research comparison, but that is close to where the similarity ends. Keyword Planner is a Google Ads feature that returns volume, competition, and CPC data for any keyword you type in, sourced directly from Google's own search systems. Keyworddit does something narrower and more specific: point it at a subreddit with 10,000 or more subscribers and it scans comment threads for the terms people actually use, then attaches monthly search volume from Grepwords to each one. One is a general-purpose forecasting tool built for advertisers; the other is a single-purpose discovery tool built to surface authentic community language before you commit to a broader research plan.

Google Keyword Planner

Free keyword research and forecasting tool from Google, built into Google Ads with search volume data direct from the source

Full review →

Google Keyword Planner is a free tool inside the Google Ads interface. Type in a seed keyword, phrase, or landing page URL and it returns related suggestions with search volume, competition level, and average CPC, along with a forecasting tool that projects clicks and impressions for a given bid. The data comes directly from Google's own search systems, which is why SEOs keep using it as a free cross-reference even when they have a dedicated paid tool.

Without active ad spend on the connected account, search volumes display as wide ranges like 1K to 10K rather than a specific number, and you need to set up a Google Ads account and billing profile to access the tool at all, even if you never spend a cent on ads. There is no keyword difficulty score, no SERP analysis, and nothing resembling Keyworddit's community-language angle; it works from Google's own keyword database, not from any single online community's discussions.

For teams that want a general-purpose keyword forecasting tool at zero cost, particularly those already running Google Ads, Keyword Planner is the more complete option of the two by a wide margin. It just does not do what Keyworddit does: surface the specific vocabulary a niche community uses when talking about a topic.

Keyworddit

Extract real keywords from Reddit subreddits with monthly search volume data, completely free

Full review →
Keyworddit screenshot

Keyworddit does one thing: you type in a subreddit name, it scans that community's comment history, and it returns the keywords people actually use most often, each paired with a monthly search volume figure from Grepwords. The idea is that Reddit comments reflect how real people describe problems and ask questions, which is often more authentic and less sanitized than the phrasing that shows up in a standard keyword database.

The tool is deliberately narrow. It only works on subreddits with 10,000 or more subscribers, since smaller communities do not generate enough comment volume for meaningful keyword frequency data. There is no rank tracking, no backlink analysis, no CPC data, and no API. Each result comes with a context link to a Google search combining the keyword and subreddit name, which helps you verify how a term is actually being used when the meaning is not obvious from the keyword alone.

Keyworddit is not trying to replace a full keyword research workflow, and it does not pretend otherwise. It is a free first step: run a subreddit through it, export the results to CSV, and take the authentic-language list into Keyword Planner, Ahrefs, or Semrush for volume validation and competition analysis. Used that way, it fills a gap that neither Keyword Planner nor most paid tools address at all.

These two are not really competitors; they are complementary free tools that answer different questions. Keyword Planner tells you roughly how many people search for a term and what advertisers pay for clicks on it. Keyworddit tells you what real people in a specific community actually call that same topic. Neither replaces the other, and both cost nothing to try.

Bottom line

If you only have time for one free tool and need volume, competition, and CPC data across any topic, use Google Keyword Planner. If your content or product targets a specific, active subreddit and you want to write in the language that community actually uses rather than the language a keyword database assumes, run Keyworddit first and feed its output into Keyword Planner or a paid tool afterward. Used together, in that order, they cover more ground than either does alone.

Frequently asked questions

Should I use Google Keyword Planner or Keyworddit for finding niche content ideas?

Keyworddit is the better starting point for niche content ideas since it extracts the actual vocabulary a specific subreddit uses, which surfaces angles a standard keyword database misses entirely. Google Keyword Planner is better once you have a shortlist of terms and need volume, competition, and CPC data to prioritize them.

Is Keyworddit's search volume data as reliable as Google Keyword Planner's?

No single sentence settles this cleanly: Keyworddit sources its volume figures from Grepwords, which the tool itself describes as similar to Google Keyword Planner data but recommends cross-referencing for accuracy. Keyword Planner's volume comes directly from Google's own search systems, making it the more authoritative source when precision matters, though it only shows ranges without active ad spend.

Can I run Keyworddit on any subreddit?

Only subreddits with 10,000 or more subscribers return results in Keyworddit. Smaller or newer communities do not generate enough comment volume for the tool to extract meaningful keyword frequency data, so there is no workaround for niche subreddits below that threshold.

Does Keyworddit have an API like Google Keyword Planner does?

No, Keyworddit has no API, no integrations, and no automation options; every search is a manual, single-page session with CSV export as the only way to move data elsewhere. Google Keyword Planner offers programmatic access through the Google Ads API for teams that want to automate keyword pulls.

Why would I use Keyworddit instead of just searching Reddit directly?

Reddit's own search returns posts and threads, which you would have to read manually to spot recurring language. Keyworddit instead extracts and counts the most frequently used keyword phrases from comments within a subreddit and attaches search volume data to each one, turning an unstructured browsing task into a structured, exportable keyword list.

Do I need a Google Ads account to use Keyword Planner if I only do organic SEO?

Yes, Google Keyword Planner requires setting up a Google Ads account and billing profile to access it, even if you never spend money on an actual ad campaign. Keyworddit requires no account at all, which makes it the faster option if you just want a quick, frictionless keyword pull.
