Ahrefs vs Semrush (2027): Prices, Trials and Which One to Choose

Choose Semrush if you want to test before you pay and need an all-in-one toolkit: it has a free plan, a 7-day free trial, and its SEO plan costs $139 a month ($117.33 on annual billing). Choose Ahrefs if backlink research is your priority or you only need keyword research: Ahrefs Starter costs $29 a month and its full toolkit, Lite, $129. At full-toolkit level the two cost about the same; the real differences are the entry points, the trial and what each tool is strongest at.

Ahrefs vs Semrush at a glance

Pricing compared plan by plan

Entry level

Ahrefs Starter at $29 a month covers keyword research and competitor monitoring. Semrush has no equivalent cheap plan, but its free plan lets you run a limited number of keyword and domain queries every day at no cost. If you only need occasional keyword ideas, Ahrefs Starter or Semrush's free plan will do; Starter is better for regular use.

Full toolkit

Ahrefs Lite costs $129 a month and Semrush SEO $139 on monthly billing. On annual billing, Semrush SEO drops to $117.33. Ahrefs's page says annual billing saves up to 17% but does not list annual prices; at the maximum discount, Lite would cost about $107 a month.

AI search visibility

Semrush's Starter and Pro+ plans add tools that track how your brand appears in AI-generated answers. If AI assistants already matter for your traffic, or your clients ask about it, that is a point for Semrush in 2027.

Which tool is better for what?

Three real-world scenarios

A blogger publishing four posts a month

Keyword ideas are the main need. Ahrefs Starter at $29 a month ($348 a year) or Semrush's free plan covers it. Paying $139 a month for a full toolkit only makes sense once search traffic earns more than that.

A small business doing SEO in-house

The team needs keyword research, competitor pages and a site audit for one website. Use Semrush's 7-day trial first with a prepared keyword list. If the team will use it weekly, Semrush SEO on annual billing ($1,407.96 a year) or Ahrefs Lite ($1,548 a year on monthly billing) are both reasonable; choose Ahrefs if backlinks are central to your strategy.

An agency with five clients

At this level, compare Ahrefs Standard ($249) with Semrush Pro+ ($299) and SE Ranking Growth ($279 monthly, $223.20 annual). Spread over five clients, each costs about $45 to $60 per client per month. Agencies whose clients ask about AI visibility will lean to Semrush.

Hidden costs and limits to check

1. Usage limits on reports, projects and tracked keywords differ by plan; check the limits you'll hit before buying.
2. Annual commitments save 16–17% but lock you in for a year.
3. Extra users on agency setups can add cost; confirm how each tool counts seats.
4. Paying for both. Many teams keep both tools out of habit; one is usually enough for a small team.

How to choose in 5 steps

1. Write down your main task: keyword ideas, backlinks, audits, rank tracking or AI visibility.
2. Estimate how often you'll use the tool. Weekly use justifies a full toolkit; monthly use doesn't.
3. Start free: Semrush's free plan and trial, Ahrefs Free for your site.
4. Run the same task in both with your real domain and three competitors.
5. Pick one and cancel the other; switch to annual billing once you're sure.

Ahrefs vs Semrush terms explained

• Backlink index: the database of links a tool has found across the web.
• Keyword difficulty: an estimate of how hard it is to rank in the top 10.
• Rank tracking: daily monitoring of your positions for chosen keywords.
• Site audit: a crawl of your site that lists technical SEO issues.
• AI search visibility: tracking how often your brand appears in AI-generated answers.

What to test during a free trial

A trial is only useful if you run the same jobs you'll run every week. Before starting Semrush's 7-day trial or Ahrefs Starter, prepare three things: your domain, three competitor domains and a list of 20 keywords you care about. Then check, in each tool, how fast you find keyword ideas you didn't already know, whether the competitor pages it reports match what you see in Google, and how clear the site audit's top issues are. The tool that gives your team usable answers fastest is the right one, whatever its brand.

Our verdict

For most small businesses and freelancers starting with SEO, Semrush is the safer first choice: you can use its free plan, run a 7-day trial on your real site, and its SEO plan covers almost everything a small team needs, with AI search tools if you need them. Ahrefs wins on entry price and backlinks: Starter at $29 is the cheapest way to do regular keyword research, and teams whose strategy depends on links often prefer its data. At full-toolkit level, the price difference ($129 vs $139) is too small to decide on; decide on the task you do most and the data you trust after testing both.

How we compiled this page

We compared both tools' official pricing pages on October 29, 2026, and focused on what small teams pay for and use: entry prices, trials, free options and annual savings.
