Keyword Difficulty Checker — Free KD Score
and SERP Analysis Tool
Enter a keyword and select your country above. The tool returns a difficulty score from 0 to 100, the current top 10 SERP with DA and DR for each result, an estimated time to rank for a new or low‑authority site, and a recommended link count to be competitive.

What Keyword Difficulty Actually Measures
Most KD scores are a function of the backlink strength of pages currently ranking in the top 10. Ahrefs KD is purely link‑based; Semrush adds domain authority signals; Moz uses page and domain authority. This tool combines top‑10 DR averages, referring domain counts, and SERP feature presence.
The practical takeaway: The SERP analysis (actual DA/DR of ranking pages) is more useful than the headline KD number.
Why the SERP Breakdown Matters More Than the KD Score
Who's actually ranking: A KD 45 with Wikipedia and government sites is harder than a KD 45 with niche blogs.
Weakest spots: Positions 7‑10 often have lower DR — realistic initial targets.
AI Overviews: If present, organic traffic per position is reduced. The tool flags this.
Content format signals: Google's preferred format for the query is visible in the SERP.
Interpreting the KD Scale: What Each Range Actually Means
| KD Range | Description | Typical Top‑10 Profile | Realistic Strategy |
|---|---|---|---|
| 0‑20 | Low competition | DR 5‑35, 10‑50 RDs/page | Content quality + 5‑10 links, 2‑4 months |
| 20‑40 | Medium‑low | DR 20‑50, 30‑200 RDs | 10‑25 links, 3‑6 months, PBN + niche edits |
| 40‑60 | Medium‑high | DR 40‑65, 100‑500 RDs | 20‑60 links, 6‑12 months, mixed tactics |
| 60‑75 | Hard | DR 55‑75, 300‑2,000 RDs | 50‑150+ links, 12‑24 months |
| 75‑90 | Very hard | DR 65+, 1,000+ RDs | 18‑36 months, editorial PR |
| 90‑100 | Extremely hard | Major brand monopoly | Not realistic without years of authority |
Choosing Realistic Keywords for a New or Low‑Authority Site
The DR parity rule: Your DR should be within 10‑15 points of the average DR of pages at positions 6‑10 before investing heavily.
Start with KD 20‑35: Lower competition builds traffic, crawl priority, and DR for harder keywords.
Look for intent mismatches: Outdated SERP results or partial intent matches create opportunities at higher KD.
Check SERP volatility: High volatility means Google hasn't settled — easier to enter.
How Link Count Relates to KD: The Tool's Recommendation Logic
The recommendation is based on the average referring domain count of pages at positions 6‑10, minus your current estimated RDs, adjusted for link type mix. Positions 6‑10 are a realistic 6‑12 month target.
The raw count assumes high‑quality dofollow contextual links. Lower‑authority links require proportionally more. On‑page quality is assumed to be strong — fix content issues before building links.
Frequently Asked Questions
All KD calculations use different inputs. This tool combines DR averages, RD counts, and SERP features. The SERP breakdown is more useful than the headline score.
KD 20‑35 is realistic. These keywords have pages at DR 20‑45, achievable with 10‑25 quality links over 3‑6 months.
It's a total referring domain target. A practical mix: 25 PBN links + 8 niche edits + 7 guest posts over 8‑12 weeks.
This tool notes when an AI Overview is present. Organic positions may deliver less traffic when AI Overviews capture clicks.
It's a range based on average outcomes for similar sites. Existing topical authority and content quality accelerate results; algorithm changes can shift timelines.
