Rankar vs LowFruits: Low-Competition Keyword Discovery Compared

Quick comparison

A short side-by-side before the detail. Every line describes what each product actually does rather than marking a box.

What is LowFruits?

LowFruits is a keyword research tool built specifically to find low-competition keywords by analysing the actual SERP for each candidate term. Its bulk SERP checker can analyse large batches of keywords at once, importing lists from CSV or Excel, and flags 'weak spots': low-authority pages ranking in the top 10 that a new or smaller site could realistically outrank [2](https://lowfruits.io/features/bulk-serp-tool/).

Its keyword clustering tool groups related queries by SERP overlap or semantic similarity, using a rule that keywords sharing at least 40% of ranking URLs belong in the same cluster, which helps a publisher write one article that targets several related terms at once [5](https://lowfruits.io/docs/kw-clustering/).

LowFruits also includes competitor keyword and sitemap extraction and a basic keyword rank tracker, but its core identity and marketing are built entirely around finding 'low fruit' keywords, meaning genuinely winnable ones, rather than being a general-purpose SEO platform.

What is Rankar?

Rankar is an all-in-one SEO and agency platform. RankSearch covers keyword research, volume, difficulty, clustering and question discovery. RankSpy adds competitor research: organic competitors, keyword gaps, missing keywords, a competitor SEO report across up to 20 domains, and a raw 0 to 1,000 domain rank score, with manual competitor entry always available.

Between them, RankSearch and RankSpy cover a similar underlying goal to LowFruits, finding keywords worth targeting and understanding how tough the competition is, but Rankar also adds rank tracking, site audits, backlinks, AI search visibility and content writing in the same workspace.

Feature comparison

LowFruits is narrower but more purpose-built for its specific job: nothing else in this comparison scores SERP weakness as directly as its weak-spot flags. Rankar's RankSearch plus RankSpy combination covers more ground but does not offer that same single-purpose weak-competitor signal out of the box.

SERP weakness analysis vs domain rank scoring

LowFruits' weak-spot detection works at the level of an individual search result: for each keyword, it checks whether the current top-10 pages come from low-authority domains, which is a very direct signal for 'can I outrank this page'. This is arguably the most specific competitive-weakness signal of any tool covered in this series.

RankSpy works at the domain level rather than the individual-result level: its 0 to 1,000 raw domain rank score gives a general sense of a competitor's overall strength, and its keyword gap report shows which keywords a competitor ranks for that you do not. It is a broader competitive intelligence view rather than a per-keyword weakness scan, so a team wanting LowFruits' exact granularity will not find an identical feature in RankSpy.

Clustering approaches

LowFruits offers two distinct clustering methods, SERP clustering based on shared ranking URLs and semantic clustering based on shared word patterns, and lets users adjust the similarity threshold themselves [5](https://lowfruits.io/docs/kw-clustering/). That flexibility suits a technical SEO who wants to tune how tightly keywords are grouped.

RankSearch's clustering is intent-based and designed to flow straight into a content brief without manual threshold tuning, prioritising a fast path from keyword list to article outline over granular control of the clustering method itself.

Credit-based pricing in both products

LowFruits runs entirely on a credit system: the Standard plan is $20.75 per month billed annually (or $29.90 monthly) with 3,000 credits, and pay-as-you-go packs range from $25 for 2,000 credits up to $250 for 50,000 credits, with credits expiring after a year [1](https://lowfruits.io/pricing/). The vendor's own documentation notes cost varies widely by seed keyword breadth, a narrow search might cost $0.50 to $1.50 to analyse, while a broad seed like 'car' can cost $10 to $15 [3](https://lowfruits.io/docs/how-many-credits-would-i-need-to-find-low-fruit-keywords/).

Rankar also uses a credit model, but credits are shared across every tool rather than being specific to keyword and SERP analysis: keyword research, rank tracking, audits, competitor reports and AI visibility checks all draw from the same pool, and a wallet top-up is available when the plan allowance runs out instead of forcing an upgrade.

Rank tracking included with keyword tools

LowFruits' Standard plan bundles a basic keyword rank tracker with 100 tracked keywords, which is a convenience for a niche site owner who does not want a separate tracking subscription [1](https://lowfruits.io/pricing/).

RankTracker inside Rankar is a fuller rank tracking product: tracking by country, language and device, tags and groups, SERP feature visibility, competitor gap tracking and scheduled white-label reports, available from 25 keywords on the Free plan up to tens of thousands on higher tiers.

How the day-to-day workflow differs

A LowFruits workflow starts with a broad seed keyword, expands it into hundreds or thousands of long-tail ideas, runs a bulk SERP check to flag weak spots, clusters the survivors, and exports a content plan built almost entirely around winnability.

A Rankar workflow for the same goal would run keyword research and clustering in RankSearch, cross-check the toughest terms against a domain rank score and keyword gap in RankSpy, then move straight into a RankWriter brief, with rank tracking and site audits available in the same project once content is published.

Where Rankar differentiates

Rankar's advantage is breadth: the same subscription that helps find winnable keywords also tracks rankings once content is live, audits the site technically, checks AI search visibility and drafts the content itself, none of which LowFruits offers.

Shared, non-expiring credits across every tool also give more flexibility than LowFruits' keyword-and-SERP-specific credits that expire after a year.

Where LowFruits is stronger

LowFruits' weak-spot detection is genuinely more specific than anything in RankSpy: it checks the actual top-10 result pages per keyword and flags authority weaknesses directly, which is exactly the signal a niche site builder or affiliate publisher needs, and Rankar has no feature that replicates that exact per-result weakness check.

Its bulk SERP checker processing thousands of keywords in one pass, and its adjustable SERP/semantic clustering thresholds, also give more manual control over the clustering method than RankSearch's more automated approach.

Who should choose Rankar

Agencies and content teams that want keyword and competitor research connected to rank tracking, audits and a content studio, without buying a separate keyword-gap tool, will get more overall value from Rankar's single subscription.

Who should choose LowFruits

Niche site builders, affiliate publishers and solo SEOs whose main task is finding genuinely low-competition keywords at scale, and who are comfortable using a separate tool for tracking, writing and technical audits, will get sharper weak-spot detection from LowFruits.

Final comparison

LowFruits and Rankar approach the same underlying problem, finding keywords worth targeting, from different angles. LowFruits goes deep on one very specific signal, SERP weakness, with a credit-based tool built for niche site and affiliate workflows. Rankar spreads that discovery across RankSearch and RankSpy and connects it to tracking, audits and content, trading LowFruits' sharpest single feature for a broader platform.
