Google Keyword Planner vs LowFruits in 2026: Free ad-platform data vs paid SERP weakness analysis
One is a free Google Ads feature that reports search volume in ranges. The other is a paid tool built to find keywords where low-authority sites already rank.
Google Keyword Planner
LowFruits- Google Keyword Planner is completely free and pulls search volume directly from Google, while LowFruits starts at $20.75 per month (billed yearly) or from $25 in one-time pay-as-you-go credits.
- LowFruits bulk-analyzes SERPs to flag positions held by low-authority sites, a more direct competition signal than Keyword Planner's ads-focused Competition label.
- Keyword Planner shows search volume as broad ranges unless the connected account has active Google Ads spend, which limits precision for pure organic teams.
- LowFruits pulls long-tail keyword ideas from Google Autocomplete using wildcard searches, plus keyword clustering to group them by intent, neither of which Keyword Planner offers.
- Keyword Planner has documented API access through the Google Ads API, while LowFruits has no API on any plan.
- LowFruits subscription credits reset monthly and do not roll over, while Keyword Planner has no usage limits or credits to manage at all.
Google Keyword Planner and LowFruits solve different halves of the keyword research problem. Keyword Planner tells you how many people search for a term, using Google's own advertiser data, at no cost. LowFruits tells you whether you can actually rank for that term, by fetching the live SERP and flagging positions held by weak, low-authority sites instead of relying on a modeled difficulty score. Neither replaces the other: Keyword Planner has no organic competition signal beyond an ads-focused Competition label, and LowFruits does not report raw search volume at all. The choice comes down to which half of the research process you are missing.
The tools at a glance
Google Keyword Planner
Free keyword research and forecasting tool from Google, built into Google Ads with search volume data direct from the source
Google Keyword Planner is the free keyword tool built into Google Ads. Enter a seed term, phrase, or landing page and it returns related keyword ideas alongside search volume, CPC, and an advertiser-facing Competition label. Because the data comes straight from Google's own search systems, it is the closest thing to a ground-truth volume number that costs nothing to access.
The catch is precision. Accounts without active Google Ads spend see volume as a wide range, such as 1,000 to 10,000 monthly searches, rather than a specific figure. There is also nothing in the tool that speaks to organic ranking difficulty; the Competition label reflects ad auction pressure, not how hard a keyword is to rank for organically.
Against LowFruits specifically, the gap is clear: Keyword Planner has no SERP-level competition analysis, no keyword clustering, and no way to identify which of its keyword suggestions are actually winnable for a given domain. It is a volume and CPC lookup, nothing more.
| Feature | Free Free |
|---|---|
| Search volume data | Yes (ranges unless active ad spend) |
| CPC data | Yes |
| Keyword difficulty / competition scoring | Ads Competition label only, no organic KD score |
| API access | Yes (Google Ads API) |
| Bulk keyword upload | Yes |
LowFruits
Bulk SERP analysis that finds low-competition keywords by spotting weak spots other tools miss with generic KD scores
LowFruits starts from a different premise than most keyword tools: modeled difficulty scores are unreliable because they estimate competition rather than examining who is actually ranking. Instead, it bulk-fetches the live SERP for every keyword in your list and flags positions held by low-domain-authority sites, thin content, or weak title relevance, which is a far more direct signal that a term is winnable for a smaller or newer site.
The Keyword Finder adds a discovery layer on top, pulling long-tail suggestions straight from Google Autocomplete using wildcard searches, and automatic clustering groups related terms by intent so you are not manually sorting a raw list into a content plan. Subscription plans also add competitor keyword extraction and a Domain Explorer covering more than 150,000 known low-authority sites.
What LowFruits does not do is report search volume as its primary output, and it has no API on any plan, subscription or pay-as-you-go. It is a focused opportunity-finding tool, not a full SEO platform, and it is priced accordingly: Standard runs $20.75 a month billed yearly, and one-time credit packs start at $25 for project-based work.
| Feature | Standard $20.75/month (billed yearly) | Premium $62.45/month (billed yearly) | Pay-As-You-Go From $25 one-time |
|---|---|---|---|
| Credits per month | 3,000 | 10,000 | Varies by pack |
| Competitor keyword extractions | 30/month | 70/month | Not included |
| Tracked keywords | 100 | 500 | Not included |
| Domain Explorer | Yes | Yes | No |
| API access | No | No | No |

Which should you choose?
Google Keyword PlannerLowFruitsGoogle Keyword PlannerLowFruitsGoogle Keyword PlannerLowFruitsThese two are not really substitutes for each other. Keyword Planner is a volume and CPC lookup with no organic competition signal; LowFruits is a competition and opportunity finder with no volume database. Most serious keyword research workflows end up using both: Keyword Planner (or a similar volume source) to size a market, LowFruits to filter that list down to what a specific domain can realistically rank for. If forced to prioritize spend, LowFruits is where the money is better placed, because knowing a term gets 5,000 searches a month is far less useful than knowing whether your site has any chance of ranking for it.
Bottom line
Start every keyword list in Google Keyword Planner, since it costs nothing and the volume data is Google's own. If you are building a new or lower-authority site, the $20.75 LowFruits Standard plan is worth adding on top, because it answers the question Keyword Planner cannot: which of those keywords can you actually win. Skip LowFruits only if your site already carries enough authority that competition filtering matters less than raw demand.
Frequently asked questions
Is LowFruits worth paying for if Google Keyword Planner is free?
LowFruits is worth paying for if your bottleneck is knowing which keywords you can actually rank for, not how many people search them. Google Keyword Planner reports search volume for free but has no organic competition signal beyond an advertiser-facing Competition label, so it cannot tell you whether a keyword is winnable for your domain. LowFruits fills that specific gap for $20.75 a month.
Does LowFruits show search volume like Google Keyword Planner does?
Not directly. LowFruits is built around SERP weakness analysis, flagging keywords where low-authority sites are already ranking, rather than a raw search volume database. If you need Google-sourced volume figures specifically, pair it with Keyword Planner or another volume-focused tool.
Which tool is better for a brand-new website with no domain authority?
LowFruits is the better fit for a brand-new website, because its SERP weakness analysis is designed to surface keywords where low-authority domains already rank in the top 10. Google Keyword Planner will tell you a keyword gets 1,000 to 10,000 searches a month but says nothing about whether a new site stands a chance of ranking for it.
Can I use Google Keyword Planner data inside LowFruits, or the other way around?
There is no direct integration between the two. You would need to export a keyword list from one and import it manually into the other, for example generating volume estimates in Keyword Planner and then running that list through LowFruits' SERP analysis for competition data.
Does either tool have an API for pulling data into a reporting dashboard?
Google Keyword Planner does, through the Google Ads API with a developer token. LowFruits does not offer API access on any current plan, so its data has to be pulled manually or exported to CSV.
Is LowFruits or Google Keyword Planner better for agencies managing multiple clients?
Neither is purpose-built for agency-scale reporting. Google Keyword Planner is free per Google account, so cost is not the constraint, but it has no client-organization structure at all. LowFruits Premium supports more credits and tracked keywords but still has no white-label export or API, so agencies typically use both as data sources feeding a separate reporting tool rather than as the reporting layer itself.
