What is Ahrefs Keyword Difficulty (KD)?
Ahrefs Keyword Difficulty (KD) is a unique metric which shows how difficult it is to rank for a specific keyword in Google’s top 10 organic results.
It’s scored on a scale of 0 to 100 in a logarithmic fashion, where 0 is nearly effortless and 100 is practically impossible without a huge amount of domain authority and backlink profiles.
How Does Ahrefs Calculate KD? The Core Algorithm
Ahrefs is different from tools that mix up a lot of different metrics. It mainly looks at one thing: Backlinks. Specifically it looks at Backlinks, from Unique Referring Domains. Here is how it works:
KD 0-10 (Easy)
You require between 0 and 10 backlinks to rank. Good for brand new websites with low domain authority.
KD 11-30 (Medium)
Needs approximately 11 to 36 referring domains. Good for sites that have some authority already built up.
KD 31-70 (Hard)
Requires between 37 and 200+ referring domains. High competition, needs dedicated and aggressive link building campaigns.
KD 71-100 (Super Hard)
Requires 200-1000+ domains. Usually dominated by household names (eg. Wikipedia, Forbes, Amazon).
Visual Data Analysis: Decoding Difficulty
Why KD is Just One Piece of the Puzzle
Beginners often make the mistake of treating Ahrefs KD as gospel. KD is a guideline not a rule Here’s why you may rank (or not) regardless of KD:
1. Search Intent Mismatch
If a keyword is 5 KD but the user wants to download a software and you make a blog post you will not rank. Google is most concerned with format and intent.
2. Topical Authority
If you blog only about “Dog Training”, you have a better chance of ranking for a KD 40 dog leash keyword than a large general-news site. Niche knowledge wins.
3. Content Quality & UX
Backlinks get you to the first page, UX keeps you there. If users click and immediately bounce back to Google (pogo-sticking) your rankings will suffer.
Strategic Workarounds: Targeting High KD
What if your business really needs to be at the top of the list, for a keyword that's very hard to get with a keyword difficulty of 80? Do you just stop trying? No. Here are some things that work from the Digi Schema playbook:
Hub & Spoke Model
Make a huge “Hub” page for the high KD keyword. “Write dozens of smaller “Spoke” articles targeted at low KD, long-tail variations and link them all back to the Hub.
Long-Tail Modifiers
Instead of broad terms like “Digital Marketing” (KD 95) target specific queries like “Digital Marketing strategies for local bakeries” (KD 12).
Leverage Video SEO
Ahrefs KD is for normal web pages. A YouTube video can be ranked on the first page of Google for a high KD keyword much more easily than a normal blog post.
Frequently Asked Questions (FAQs)
AEO Optimized answers questions about Ahrefs metrics complexities.
What is a good Keyword Difficulty score in Ahrefs?
When you want to get a score you need to think about your websites Domain Rating. If your website is new and has a Domain Rating of 0 to 15 you should try to use keywords that have a KD of 0 to 15. If your website is medium and has a Domain Rating of 30 to 50 you can try to use keywords with a KD of 15 to 40.. If your website is established and has a Domain Rating of 60 or more then you can compete for keywords that have a KD of 50 or more.
Does Ahrefs KD account for on-page SEO?
No. The Ahrefs Keyword Difficulty is figured out mostly by looking at the backlink profiles which're the websites that link to the top 10 pages that show up in search results. The Ahrefs Keyword Difficulty does not look at how good the content's how many times a keyword is used or how fast a website is. The Ahrefs Keyword Difficulty is, about the backlink profiles of the top 10 ranking pages.
Why is Ahrefs KD different from Semrush KD?
Ahrefs looks at the number of websites that link to a page, which is called referring domains or backlinks to figure out how hard it is to rank for a keyword. Semrush does things a bit differently. It uses a lot of things to come up with its score like how important a website is, what people are trying to accomplish when they search for something and other things that are, on the actual webpage. This means that Ahrefs and Semrush can give scores for the same keyword.
Can I rank for a high KD keyword without backlinks?
This is something that does not happen often but it can happen. If the websites that are currently at the top of the search results do not give people the information they are looking for and you write something that really answers what the person is asking Google may put your website above others that have links to them. Google likes it when a website is really good at talking about a topic so if your website is very good at that Google may rank you higher, than other websites.
