Semrush free trial, and the three things nobody publishes

Search for the Semrush trial and you will find twenty pages telling you it is seven days with no credit card required. The seven days is right. The second half is something nobody can show you, because Semrush does not publish it anywhere.

I went and read both of their own pages on 20 August 2026. Here is what is actually there, and what isn’t.

What Semrush actually publishes

That’s it. Four facts, from two pages.

The three things neither page says

Whether a payment method is required. Not on the pricing page, not on the trial page. You find out at the signup screen. This is the single most-asked question about the trial and the vendor answers it nowhere a search engine can read.

What happens on day eight. “Cancel anytime” implies there is something to cancel, which implies a subscription that continues. Neither page says so outright. Assume billing starts and put a reminder in your calendar for day six. An email you might miss is not a plan.

What you are limited to during the trial. No report caps, no crawl limits, no row limits are published for the trial period. A trial with the same caps as the Free plan and a trial with full Pro+ access are completely different offers, and you cannot tell which one you are getting until you are inside it.

None of that makes Semrush unusual. It makes the confident write-ups wrong.

It isn’t one trial, it’s seven

The trial page doesn’t offer “the Semrush trial”. It offers a trial per toolkit: Semrush One, SEO, Content, Traffic & Market, Advertising, Local, and Social.

That matters more than it sounds. If you trial the SEO Toolkit and your actual reason for considering Semrush is the advertising data, you have spent your seven days testing the half of the product you were never going to buy it for. Decide which toolkit answers your question before you start the clock, not after.

Seven days buys you three real checks

Don’t try to see everything. You’ll open forty reports, understand none of them, and let the trial lapse. Three checks, on your own domain, in this order:

1. Create a project and connect Google. Do it in the first ten minutes. Semrush without your Analytics and Search Console attached is showing you estimates you could already get for free.
2. Run Site Audit. It produces a prioritised list you can act on whether or not you subscribe, which makes it the one check with a payoff even if you walk away.
3. Run Keyword Gap against two real competitors. This is the report Semrush is genuinely best at, and it’s the fastest way to know whether the data changes what you’d do next week.

The full tutorial is the map if you want more than three, but three is what seven days honestly holds.

The trial won’t show you the tier boundary

This is the part that catches people, and it’s why the trial is a worse buying signal than it looks.

I recorded six hours of Semrush on the Pro tier, and the recording is full of reports that were simply locked: share of voice, device and location breakdowns in Position Tracking, keyword tagging, the cannibalisation report, the JavaScript impact report in Site Audit. Six things I’d have used that week, one tier above what I was paying for.

A toolkit trial does not tell you which of the reports you just enjoyed will still be there on the tier you can afford. That answer is in the plan limits, not in the product, and it’s worked through on what Semrush actually costs. Read it during the trial, while you can still check whether the report you fell for is on the tier you’d buy.

If you’d rather not start a clock

The free plan has no expiry: one demo project, ten reports a day. That’s genuinely enough to look up a competitor, check a domain, or settle an argument about search volume. It is not enough to build a keyword map, and it never becomes enough by being patient.

Use the free plan to decide whether you want to test Semrush. Use the seven days to test it. Doing those in the wrong order is how the trial gets wasted.
