Semrush wants you on a $299-a-month trial before you’ve typed a single keyword. You can skip it, and the free account still answers real keyword questions. We signed up, skipped the trial, ran one full keyword lookup, and wrote down every number the screen showed us.
Why Look at Semrush Keyword Research on a Free Account
A free Semrush account includes “10 reports per day across all vital tools,” according to Semrush’s own subscriptions and toolkits page. That is enough to research a handful of keywords properly, but not enough to browse.
Most Semrush keyword research guides are written by Semrush itself. Search for the term in the US and the top results are Semrush pages, top to bottom. They explain every button. What they don’t tell you is what a brand-new free user actually sees, and where the sign-up flow nudges you toward paying.
That’s the gap this review fills. We’re an independent site that tests creator tools on free plans, and we ran Semrush through the same task list as every other SEO tool we cover.
Is one lookup enough to judge a tool this big? Not for everything. But it’s enough to show you what the data looks like, how to read it, and what you’ll hit first when you try it yourself.
Key Takeaways
One Keyword Overview lookup on a free account gave us volume, difficulty, intent, CPC and a country breakdown for a single keyword, with a daily cap of 10 reports across all tools (Semrush). The data is solid; the limit is the catch, and the default sign-up path is a paid trial.
Quick Verdict: Is Semrush Keyword Research Worth It on a Free Account?
Yes, for checking a few keywords a day: our single Keyword Overview lookup returned seven separate metrics for one term, including a difficulty score with a plain-English rating. No, if you need to build a full keyword list in one sitting; 10 reports a day runs out fast.
Here’s how we’d sum it up:
| What we found | |
|---|---|
| Best for | Checking a short list of keywords you already have in mind |
| Data on one lookup | Volume, global volume by country, difficulty, intent, CPC, competitive density, number of ads |
| Daily limit | 10 reports per day across all tools (Semrush) |
| Biggest friction | Sign-up ends on a $299/month Pro+ trial offer; the free path is a smaller “Skip trial” button |
| Not tested by us | Keyword Magic Tool, Keyword Gap, Keyword Strategy Builder |
Does that make Semrush the best free keyword tool? Not on its own. It makes it a precise one, with a tight daily budget. If that sounds like what you need, read on for how to get the most out of those 10 reports.
How We Tested Semrush Keyword Research
We tested Semrush on October 21, 2026, on a free account created with Google sign-in, with no card entered. We ran the same tasks we run on every SEO tool we review:
- Sign up and record every screen.
- Research one English keyword in the US database.
- Run a site audit on our own domain.
- Look up backlinks for the same domain.
- Set up rank tracking for one keyword.
- Write down every free limit the tool shows.
For keyword research, we used one keyword across every SEO tool we test: “generative engine optimization.” Same keyword, same country, same day. That lets us compare tools fairly later.
Why that keyword? It’s a real term in our own niche, it has meaningful volume, and it’s competitive enough to make the difficulty score interesting.
We copied numbers straight from the screen and kept masked screenshots. Everything in this review that says “we saw” comes from that log. Anything we didn’t test is labeled that way.
What One Keyword Overview Lookup Showed Us
Keyword Overview reported a US search volume of 9.9K for “generative engine optimization,” with a Keyword Difficulty of 72% labeled “Hard.” That one screen held seven separate metrics. Here’s each one, what we saw, and how to read it.
| Metric | What Semrush showed | How to read it |
|---|---|---|
| Volume (US) | 9.9K | Average monthly searches in the US database |
| Global Volume | 22.9K | Monthly searches across all countries Semrush tracks |
| Keyword Difficulty | 72% “Hard” | How hard it is to reach Google’s top 10 for this term |
| Intent | Informational | People want to learn, not buy |
| CPC | $14.49 | What advertisers pay per click on Google Ads |
| Competitive Density | 0.60 | How crowded the ad side of the keyword is |
| Ads | 12 | The ads figure Semrush showed for the term |
Volume and global volume
The US figure (9.9K) was less than half of the global figure (22.9K). The country breakdown showed Germany at 2.4K, India at 2.4K, the Netherlands at 1.9K, the UK at 1.6K and France at 1.3K.
What does that tell you? If you write for a US audience, plan around 9.9K, not 22.9K. The global number is useful only if your site serves those other countries too.
Keyword Difficulty
Semrush rated the keyword 72% and labeled it “Hard,” with a note that it “will demand 124 high-authority referring domains.” That note is the most practical line on the page. It turns an abstract score into a concrete target: how many other sites would need to link to you.
Semrush’s own documentation puts 70–84 in the “Hard” band and 85–100 in “Very hard” (Semrush KD guide). So 72% sits at the easier end of Hard. For a new site, that’s still a long road. For a site that already earns links, it’s a stretch goal.
Intent, CPC and competition
Intent came back as Informational. That matches the keyword: people searching “generative engine optimization” mostly want an explanation. If you’re selling a service, this keyword is better for a guide that leads to your offer than for a sales page.
The CPC of $14.49 is high for an informational term. That’s a signal worth noticing. Advertisers are paying real money for these clicks, which usually means the topic is close to a buying decision somewhere down the line.
Competitive density of 0.60 and 12 ads back that up. The ad side of this keyword is busy.
The upsell on the same screen
Right on the Keyword Overview page, Semrush added: “Go beyond basic volume and discover advanced metrics with Semrush Pro.” So the free view is a summary. It’s a good summary, but some deeper reports sit behind the paid plan.
Using Keyword Difficulty Bands to Pick Your Keywords
Semrush’s own guide calls the 0–14 band “the best opportunities to start ranking new web pages on Google” (Semrush KD guide). That makes the band, not the exact number, the most useful thing to read on a free account. Here is what Semrush says each band takes, paraphrased from that guide.
| KD% | Semrush label | What Semrush says it takes |
|---|---|---|
| 0–14 | Very easy | Best place to start ranking new pages |
| 15–29 | Easy | Some competition, still achievable even on a new domain |
| 30–49 | Possible | Quality, well-structured content optimized for the keyword |
| 50–69 | Difficult | Good content plus some quality backlinks |
| 70–84 | Hard | A lot of effort on better-quality backlinks |
| 85–100 | Very hard | A lot of effort on both content and links |
How does our test keyword fit? At 72%, “generative engine optimization” sits two bands above where Semrush says a new site should start. Our own site is new. So if we were choosing a keyword to write for, the honest move would be a longer, more specific version of that term in a lower band.
That’s the real job of keyword difficulty on a free plan. It doesn’t tell you whether a keyword is good. It tells you whether it’s good for you, right now.
When we compared the score with the “124 high-authority referring domains” note, the two pointed the same way. The band gives you the label; the note gives you the size of the climb.
Signing Up: The Trial Path vs the Free Path
Semrush’s sign-up flow ended on a plan page offering “Pro+ $299/mo … 7 days free, then $299/mo,” with “Get free trial” as the main button and “Skip trial” as the smaller one. If you only want the free account, look for “Skip trial.”
Was the rest of sign-up a hassle? No, it was quick. Google sign-in asked only for name, profile picture and email address. Then three survey questions: your role, your experience and your marketing focus.
Honestly, the trial screen is where a beginner could slip. A 7-day trial that turns into $299 a month is a big jump if you only wanted to look up a few keywords.
If you do start the trial, follow the FTC’s advice for any free trial. First: “Find the terms and conditions for the offer.” Then “make a note on your calendar to remind you to cancel before the trial ends” (FTC consumer advice). That’s good advice for every tool in this space, not only Semrush.
What the Free Account Holds Back
Semrush’s free plan includes 1 demo project and 10 reports per day across all vital tools (Semrush). We found two more limits only by running into them inside the tools.
Here is what we saw while working:
- Site Audit: “Limit per audit 100 pages,” scheduled weekly by default.
- Position Tracking: “Keyword limit 1/10,” so 10 tracked keywords at most.
- Keyword Overview: full summary numbers for our one lookup, plus the “Semrush Pro” prompt for advanced metrics.
What surprised us was where those limits live. The in-app subscription page listed only the paid plans and no summary of the free account. You learn the free limits one tool at a time.
So how should you spend 10 reports? Treat each one as a decision, not a browse. Decide which keywords you’re seriously considering first, then use Semrush to check them.
One thing we couldn’t confirm: whether every report type counts the same against that daily cap. Our test used fewer than 10 reports, so we never hit the wall.
How to Do Keyword Research in Semrush, Step by Step
Our test took six steps from a blank account to a tracked keyword, and every step below is one we actually did on October 21, 2026. It’s the shortest path we know to useful keyword data on a free plan.
- Sign up and press “Skip trial” on the plan page if you want to stay free.
- Open Keyword Overview.
- Set the database to the country you write for (we used United States).
- Enter one keyword and run the report.
- Read Volume, Keyword Difficulty and Intent first; then CPC and the country breakdown.
- If the keyword is a keeper, add it to Position Tracking (Google, Desktop, United States, English in our setup) so you can watch it over time.
That last step uses one of your 10 tracking slots. When we started tracking, the screen read “Keywords: 1 — Gathering keywords data: 0/1,” so don’t expect a ranking right away.
Position Tracking also offered more than Google as a search engine. The list included ChatGPT and Gemini. We only set up Google, but it’s a sign of where keyword tracking is heading.
What about Keyword Magic Tool, the feature most Semrush guides start with? We didn’t test it in this round, so we won’t describe how it behaves on a free account. It’s on our list.
Mistakes to Avoid With Semrush Keyword Research on a Free Plan
The free plan gives you 10 reports a day (Semrush), so every wasted report hurts. These are the five mistakes our test made easy to see.
- Planning around global volume. Our keyword showed 22.9K globally but 9.9K in the US. If your readers are American, the smaller number is the real one.
- Browsing instead of deciding. Clicking around Semrush to “see what’s there” spends reports. Pick your candidate keywords first, then check them.
- Pressing the bigger button at sign-up. The main button starts a $299/month Pro+ trial. “Skip trial” keeps you on the free account.
- Expecting rankings on day one. Right after we set up tracking, Semrush said it was still “Gathering keywords data.” Give it time before you judge a keyword.
- Treating difficulty as a verdict. A 72% score doesn’t mean “never.” It means “not yet, not without links.” Use the band to decide what to write first.
Which of these is easiest to fall into? In our experience, number 2. The interface is full of tempting links, and on a free account each click can cost you one of your daily reports.
What We Haven’t Tested Yet in Semrush
Three keyword features stayed outside this test: Keyword Magic Tool, Keyword Gap and the Keyword Strategy Builder. We’ll test each on the same free account before we write about it.
Why hold back? Because a review of a feature we haven’t used would just repeat Semrush’s own help pages, and those already rank for every one of these terms. When we test them, we’ll add the results here and link to the full write-ups.
Semrush Free vs Paid Plans for Keyword Research
The in-app subscription page listed three paid plans, starting at $199 per month for Starter and going up to $549 per month for Advanced. Here is how they line up with the free account, using only what we saw.
| Plan | Price shown in-app | What we can confirm |
|---|---|---|
| Free | $0 | 10 reports per day, 1 demo project (Semrush); 100 pages per audit; 10 tracked keywords |
| Starter | $199/month | Listed on the subscription page; not tested |
| Pro+ | $299/month | Offered as a 7-day trial at sign-up; not started |
| Advanced | $549/month | Listed on the subscription page; not tested |
That’s a steep step from $0 to $199. For many solo creators, the honest answer is to stay on the free plan, use the 10 daily reports carefully, and pair Semrush with a cheaper tool for bulk keyword ideas.
Is the paid plan worth it for anyone? If keyword research is a daily part of your job, probably. The free account shows the data quality is there. The question is only volume.
Who Should Use Semrush for Keyword Research
Use Semrush’s free account if you already have a short list of keywords and want trustworthy volume, difficulty and intent for each one; our single lookup returned all three plus four more metrics. Skip it if you need hundreds of ideas in one session.
Here’s our short guide:
- Bloggers and solo creators: the free account is enough if you check three to five keywords a day.
- Small businesses: use it to sanity-check the few keywords that matter most to your sales pages.
- Agencies and full-time SEOs: you’ll outgrow 10 reports a day quickly; the paid plans are built for you.
Not sure which group you’re in? Count the keywords you’d check on a busy day. If it’s under 10, the free account’s daily cap can cover it. Whichever group you’re in, keep one habit from our test. Pick the keyword first, then check it. The free account rewards a plan, not curiosity.
