What is a good keyword difficulty score?

It depends entirely on your site's authority. Under 30 is realistic for a new site; 30–50 needs solid content and patience; 50–70 needs consistent publishing and links; above 70 is large-site territory. Calibrate to your own domain, not to an absolute threshold.

Why do different tools give different difficulty scores?

Every tool uses its own formula and its own link index. Ahrefs weighs referring domains to the ranking pages, Semrush blends several signals, and each samples a different SERP snapshot. Compare scores within one tool; never across tools.

Is low keyword difficulty always worth targeting?

No. Low difficulty with no commercial intent produces traffic that never converts. Check the CPC and the intent alongside the difficulty — a 90/mo keyword with a $10 CPC is often worth more than a 5,000/mo informational term.

How accurate is keyword difficulty?

It is a prioritisation aid, not a prediction. It cannot see topical authority, internal linking, brand strength or how well your content actually matches intent. Use it to rank a shortlist, then judge the SERP yourself.

Keyword Difficulty Checker

See how hard a keyword really is, based on the live top 10 and the authority you would actually have to outrank.

Estimated difficulty

Easy

Why this score

• Long-tail phrase (6 words) — much easier to rank.
• Commercial modifier detected — attracts paid competition and listicles.
• Niche modifier detected — narrows the SERP to specialised results.

Recommendation

Realistic for new sites. Write a thorough, well-structured page with clear H2s and internal links.

How this keyword difficulty score is calculated

When you run a check, this tool requests the live Google top 10 for your keyword, then looks up the authority score and referring-domain count of every domain on that page. Difficulty is derived from the authority you would have to outrank — weighted mostly by the mean domain authority of the top 10, and adjusted by how heavily linked those pages actually are. A SERP of well-known domains with thin link profiles scores lower than one where every result is deeply linked.

If live SERP data is temporarily unavailable, the tool falls back to a transparent structural estimate based on phrase length, commercial modifiers and query format, and labels the result accordingly.

KD checker (free): what each score band means

"KD" is simply shorthand for keyword difficulty. Every KD checker maps the 0–100 score to a decision, and these are the bands this tool uses:

0–14 Very easy — a focused page can rank within weeks, even on a new domain.
15–29 Easy — realistic for low-authority sites with thorough content.
30–54 Moderate — needs good content plus a few months of publishing in the same cluster.
55–74 Hard — ambitious; a longer-tail variation is usually the faster route.
75–100 Very hard — established-authority territory.

Use bulk mode to score a whole list at once: paste up to 200 keywords and the easiest ones are sorted to the top, so you can pick the terms worth a live SERP check.

Keyword difficulty FAQ

How is keyword difficulty calculated?: This checker fetches the live Google top 10 for your keyword, looks up the authority and referring-domain count of each ranking domain, and scores difficulty from the authority you would actually have to outrank. It is measured from the current SERP, not from a static database.
Is the keyword difficulty checker free?: Yes. It is free to use with no signup and no credit card. Results for popular keywords are served from a shared cache so repeat lookups are instant.
What is a good keyword difficulty score?: Below 30 is realistic for a new or low-authority site. 30-55 needs solid content plus consistent publishing in the same topic cluster. Above 75 generally requires established domain authority.
Why does the score differ from other keyword difficulty tools?: Most tools score difficulty from a stored keyword index that can be weeks old. This checker reads the SERP at the moment you run it, so the score reflects who is ranking right now.
What is a KD checker?: A KD checker is a keyword difficulty checker: it scores how competitive a search term is from 0 to 100 so you can decide whether it is worth targeting. This free KD checker reads the live Google top 10 and scores the keyword from the authority of the pages already ranking.
Can I check keyword difficulty in bulk?: Yes. Switch to bulk mode, paste up to 200 keywords (one per line), and every phrase is scored instantly in your browser and sorted easiest first. Bulk scores use the structural model; run any single keyword through the live check for a SERP-backed score.

In short

Keyword difficulty estimates how hard it is to reach Google's first page for a term, on a 0–100 scale. The honest version of the number comes from the live SERP: the authority and referring-domain count of the pages currently ranking, and whether any of them are weak. A difficulty score with no SERP behind it is a guess — two keywords with identical volume can differ enormously depending on who already holds the page.

Worked example

What the output looks like

Input: Keyword: "keyword golden ratio calculator"
Output: Difficulty 12/100 — top 10 averages 21 referring domains; positions 6, 8 and 9 held by pages with fewer than 5 referring domains
How to read it: This is a genuine opening. Three of the ten results have almost no link equity, so a single well-formatted page with a working calculator can realistically take a first-page slot without any link building.

How it works

We read the live top 10

The check runs against Google at the moment you press the button, not a cached index. The score reflects who is ranking today.

Authority of the incumbents sets the score

Difficulty is driven by the link profile of the pages ahead of you, not by search volume. A 3,000/mo term held by thin pages is easier than a 200/mo term held by Wikipedia and Ahrefs.

Look for the gap, not the average

The useful signal is the weakest result in the top 10. One low-authority page at position 7 is a foothold, even when the average difficulty looks discouraging.
