Keyword difficulty answers one question: how strong is this results page? Weak spots answers a different one: how many of those results could my site actually beat, with better content and no new backlinks? Both are in the product, because both questions matter — but they are not interchangeable, and for a small or growing site, the second one is usually the question that decides what to do.
The two questions
Keyword difficulty: the strength of the market
Difficulty is a 0–100 score of how strong the pages ranking for a keyword are. It is absolute: the same for every site that looks at it, because it describes the competition, not you. It rolls up by averaging — a page’s difficulty averages its keywords’, a cluster’s averages its pages’ — which makes it a summary of a whole market at any zoom level. What is keyword difficulty?
Weak spots: your opening in it
Weak spots counts the positions in the top 10 that are held by pages your site could realistically outrank through content quality alone — because your link profile is already on a par with theirs or stronger. It is relative by construction: the same results page can show different counts to different sites, a handful of giant domains never count as beatable, and if RankDots does not know your site yet, it judges from a cautious young-site baseline until you connect Search Console. What are Weak spots?
Why an average hides the answer
Difficulty is a summary, and summaries hide distribution. Picture two keywords with identical difficulty scores. Behind the first, every ranking page is uniformly solid — decent content, decent authority, no obvious gaps. Behind the second, most results are strong but two positions are held by thin, unfocused pages that rank despite themselves. Same score; completely different situation.
The first keyword has no way in on content alone. The second one does — twice. And here is the point the average cannot see: you do not rank by beating the average of a results page. You rank by taking one specific position from one specific page. A metric that summarizes the whole page tells you the neighbourhood’s price; it cannot tell you whether there is a single door open. Counting the doors is a different measurement, and that is the measurement Weak spots was built to make.
Why the second question fits a smaller site
A large, authoritative site can afford wars of attrition: pick the market, spend on content and links, and grind the average down. A smaller site wins differently — by selection. Its advantage is not force but choice: thousands of keywords, and the freedom to pick the ones where an opening already exists.
Difficulty cannot power that strategy, because it ignores you entirely. Weak spots is computed against your standing — which also means it grows with you. Positions that read as out of reach today can become beatable as your authority builds, and the counts move when Search Console replaces the baseline with your real data. The metric is not a fixed map; it is your current reach.
Side by side
| Keyword difficulty | Weak spots | |
| The question | How strong is this results page? | How many of its results could my site beat with content alone? |
| Form | A 0–100 score | A count of beatable positions |
| Relative to your site? | No — the same for everyone | Yes — judged from your site’s standing |
| Describes | The market | Your opening in it |
| Best for | Comparing subjects and sizing up markets | Choosing what to build next |
When difficulty is still the right lens
- Comparing subjects. For triage across whole clusters, an average is exactly the right summary — Topic cluster difficulty exists so you can sort markets before you ever look at individual doors.
- Long-horizon planning. If you intend to build authority toward a hard space over quarters, difficulty maps the price of the terrain you are buying into.
- Comparing across sites. Difficulty is site-independent, which makes it the shared language when you are sizing a market for a client or comparing niches before a site exists.
Using both in the app
Choosing between clusters: sort by Topic cluster difficulty and potential. Choosing the next page to build: read Weak spots, next to Easy-to-rank search volume. Judging one keyword: read both columns together — and treat disagreement as information, not noise. High difficulty with weak spots present is the best find in the product: a strong market with a door open. When the two point different ways, remember what each is talking about: difficulty is describing the market, Weak spots is describing you. Trust Weak spots for what to do next, and difficulty for where you stand.
