Keyword Difficulty Explained for Beginners
You’ve done your keyword research. You’ve got a spreadsheet (or a tab full of screenshots) with keyword ideas, search volumes, and that one column that trips everyone up: difficulty.
Maybe it’s called “SEO Difficulty.” Maybe it’s “Competition.” Either way, you’re staring at a number next to every keyword, and you genuinely don’t know what to do with it. Is 20 good? Is 45 too high for a brand-new blog? Should you just write about whatever has the highest search volume and hope for the best?
That’s exactly what I want to clear up in this post. Keyword difficulty explained for beginners means one thing to me: understanding what that score is actually telling you so you can use it to make a real decision about what to write next, not just stare at it and guess.
I’m going to walk you through what the score measures, why I sort my own content ideas by competition level before I write a single word, and what kind of ranking timeline you can realistically expect depending on the tier a keyword falls into.
What a Keyword Difficulty Score Actually Measures
A keyword difficulty (KD) score is a tool’s estimate of how hard it will be to rank on page one of Google for a specific keyword. It’s usually shown as a number from 0 to 100, sometimes with a label like “Easy,” “Medium,” or “Hard” attached to it.
Here’s the part most beginners miss: the score isn’t measuring the keyword itself. It’s measuring the competition already sitting in the search results for that keyword. Specifically, tools look at things like:
- Authority of the ranking pages — are the top 10 results dominated by large, established sites with a lot of trust built up over years?
- Backlink profiles — how many other websites link to those top-ranking pages, and how strong are those linking sites?
- Content depth and quality — are the current top results thorough, well-structured, and clearly answering the search intent, or are they thin and outdated?
So when a tool tells you a keyword has a difficulty of 65, it’s really telling you, “The pages currently ranking for this have strong authority and solid backlinks; you’re going to be competing against that.” A score of 15 tells you the opposite: the current competition is weaker, so there’s more room for a new site to break in.
This is why I always tell people How to Do Keyword Research for Blogging (Free Tools Only): the volume and the keyword itself are only half the picture. Difficulty tells you who you’re actually up against.
Why a Young Blog Should Prioritize Low-Difficulty Keywords First
If you’re new, your site doesn’t have authority yet. Google doesn’t know you. You don’t have backlinks. You don’t have a track record of publishing consistently helpful content. That’s not a criticism; every single site starts there, including mine.
Trying to compete for a high-difficulty keyword on day one is like showing up to a race where everyone else has been training for years, and you just laced up your shoes. You might write genuinely excellent content and still not rank, simply because the competition has structural advantages you haven’t built yet: domain authority, backlinks, and historical trust signals.
Low-difficulty keywords level that playing field. If the current top-ranking pages are weaker, thinner, or from less-established sites, a well-written, genuinely helpful post from a newer blog has a real shot at breaking through. This is exactly why I sort my own content ideas into low, medium, and high competition tiers before I ever open a draft. I deliberately write my low-competition topics first, not because they’re the “best” ideas, but because they give me realistic early wins. Those wins do two things: they get me actual traffic while my site is young, and they start building the authority I’ll need to eventually take on harder keywords.
High-difficulty keywords aren’t off-limits forever. They’re just not where I start.
How to Read Difficulty Scores From Free Tools
You don’t need an expensive tool to get a workable difficulty reading. Free tools like Ubersuggest and Google Keyword Planner both give you a usable signal, though they present it slightly differently.
Ubersuggest shows an SEO Difficulty score from 0–100 for organic search. As a rough guide, I use:
- 0–29: Low competition — good target for a newer site
- 30–49: Medium — doable once you have a few solid posts and some backlinks
- 50+: High — save these for later
Google Keyword Planner doesn’t give you a true keyword difficulty score the way SEO-specific tools do. Instead, it shows “Competition” as low, medium, or high, but that column reflects competition for paid ads, not organic ranking difficulty. It’s still a useful directional signal, but I don’t treat it as equivalent to a proper SEO difficulty score. If you’re using Keyword Planner, pair it with an actual SEO tool’s difficulty metric before deciding what to write.
Whichever tool you use, remember the number is generated by an algorithm looking at backlinks, authority, and on-page signals; it’s an estimate, not a guarantee (more on that in a minute).
Once you’ve got your keyword list pulled together with volume and difficulty side by side, sorting it into tiers takes ten minutes and saves you from months of writing content that was never going to rank yet.
Why Low Volume + Low Difficulty Can Beat High Volume + High Difficulty
This is the part that trips up almost every beginner: chasing the biggest search volume number on the sheet.
A keyword with 50 searches a month and a difficulty score of 10 will very likely outperform a keyword with 5,000 searches a month and a difficulty score of 70 for a new blog in the early stages. Here’s why: if you can’t rank for the high-volume keyword at all, 5,000 monthly searches means nothing. Zero times any number is still zero. Meanwhile, ranking for the low-volume keyword actually gets you traffic, starting now.
There’s a compounding effect too. Every post that ranks and earns even a small amount of traffic can:
- Start earning natural backlinks and internal link opportunities
- Build topical relevance around your niche
- Contribute to your site’s overall authority, which makes your next post (even a harder one) easier to rank
I’d rather stack five realistic wins on low-competition keywords in month one than gamble everything on one high-volume keyword and get nothing back for eight months. Once your site has more authority, the math changes; those bigger, harder keywords become realistic. But early on, difficulty should weigh more heavily in your decision than volume does.
Realistic Ranking Timelines by Competition Tier
One of the most honest things I can tell you is that difficulty doesn’t just affect whether you rank; it affects how long it takes. Here’s what I’ve seen play out, tier by tier:
- Low competition: Often shows movement, meaning you start appearing somewhere in search results and can track progress within 1–3 months. This is the fastest tier for a new blog to get feedback that something is working.
- Medium competition: Usually takes 3–5 months before you see meaningful ranking movement, assuming consistent publishing and reasonably strong content.
- High competition: Can take 8–10+ months, and content alone often isn’t enough. These keywords typically require backlinks and stronger domain authority before Google will seriously consider ranking you above established competitors.
If you want a deeper breakdown of what affects these timelines beyond difficulty alone, I’ve covered it in How Long Does SEO Take for New Blogs?.
These timeframes aren’t a countdown clock; they’re a general expectation, so you’re not checking your rankings every single day for a high-difficulty post and getting discouraged when nothing’s moved after three weeks. Once you publish, How to Read Google Search Console as a Beginner is where you’ll actually track whether a post is gaining impressions and slowly climbing, even before it hits page one.
Difficulty Scores Are Estimates, Not Guarantees
I want to be straightforward about something: keyword difficulty scores are useful, but they are not perfect predictions. They’re generated by algorithms that estimate competition based on visible signals like backlinks and domain metrics. They can’t account for everything Google actually weighs when ranking a page, things like how well your content matches search intent, how it’s structured, page experience, and dozens of other factors that shift constantly.
You’ll occasionally see a “low difficulty” keyword that’s harder to crack than expected and sometimes a “medium difficulty” keyword that ranks faster than the score suggested. That doesn’t mean the score is useless; it means you should treat it as a filter to narrow down smart choices, not a promise. Ahrefs, one of the more transparent SEO tools, puts it plainly on their own site: because Google doesn’t disclose all of its ranking factors, keyword difficulty can only ever be an estimate. That’s true across every tool, not just theirs.
Use the score to decide what to prioritize. Then use good on-page SEO and genuinely useful content to close the rest of the gap. If you want the full process for turning a good keyword choice into a post that actually ranks, that’s covered in How to Rank Blog Posts on Google Faster.
Frequently Asked Questions
Is a keyword difficulty score the same across every SEO tool? No. Different tools weigh backlinks, authority, and content signals differently, so the same keyword can show different difficulty scores depending on which tool you use. Use one tool consistently so your comparisons stay accurate relative to each other.
What difficulty score should a brand-new blog target? Generally under 30 on most free tools, though this can shift slightly depending on the tool’s scale. The goal early on is picking off keywords where the current competition is genuinely weak, not chasing an exact number.
Can I ever rank for a high-difficulty keyword as a new blogger? Yes, eventually, but it usually requires backlinks and domain authority you likely don’t have yet. It’s smarter to build wins on lower-competition keywords first, then revisit harder ones once your site has more established trust.
Does low search volume mean a keyword isn’t worth writing about? Not necessarily. Low-volume, low-difficulty keywords are often the fastest way for a new blog to actually get found, and they add up as you publish more of them. Traffic from ten small wins is still traffic.
How often do I need to re-check a keyword’s difficulty score? Competition for a keyword can shift over time as new content gets published and older pages lose authority. If you’re revisiting an old content plan, it’s worth rechecking difficulty before assuming your original notes still apply.
Conclusion
Keyword difficulty isn’t a mysterious number you should ignore or blindly chase; it’s a filter that tells you who you’re actually competing against for a given search term. For a new blog without established authority or backlinks, prioritizing low-difficulty keywords first isn’t a shortcut or a lesser strategy; it’s the realistic path to actual traffic while you build the credibility needed to take on bigger, harder topics later.
I sort my own content ideas into low, medium, and high competition tiers before I write, and I deliberately go after the easier wins first. Low-competition keywords tend to show movement within a few months. Medium-competition keywords take longer and need a bit more consistency behind them. High-competition keywords are worth planning for, but they’re a later-stage goal that usually depends on backlinks and domain authority, not just good writing.
Remember that every difficulty score is an estimate, not a promise, a helpful starting filter, not the final word. Use it to make smarter decisions about what to write next, pair it with genuinely useful content, and let your wins compound over time.
