Ahrefs vs Semrush

Feature tables tend to give both vendors a tick for rank tracking, which hides the difference I would check first. Ahrefs refreshes tracked keywords weekly on every plan, according to its pricing table and its own Rank Tracker page. Semrush's entry plan tracks 500 keywords daily.

Ahrefs answers with volume. Lite tracks 750 keywords to Semrush's 500, and Standard tracks 2,000 to Pro+'s 1,500. Ahrefs counts one keyword in one location in one project as one tracked keyword, so a term followed in three cities uses three.

Whether weekly is enough depends on who reads the number. For a monthly client report, a weekly point is plenty. For an alert on a revenue page after a core update, a week is a long time to find out.

Two things narrow the gap. Search Console already records daily average positions for your own site at no cost. Both vendors can pull it in, Ahrefs through GSC Insights and Semrush through its report integrations. The daily third-party refresh earns its keep on competitors, which Search Console cannot show you.

Ahrefs caps extra users per plan: two on Lite, five on Standard and ten on Advanced. So Lite holds three people, Standard six and Advanced eleven, and only Enterprise is uncapped. Semrush's pricing page shows no cap, sells extra users from $45 a month, and sets the exact price by plan level.

The cap turns team size into a tier decision. Three people on Ahrefs Lite cost $108 plus two seats at $40, which is $188 a month. On Semrush's SEO plan the same three cost at least $207.33, so Ahrefs is cheaper.

Add a fourth person and Ahrefs has to move to Standard: $208 plus three seats at $60 is $388. Semrush stays on its SEO plan from $252.33. At seven people Ahrefs needs Advanced, and $374 plus six seats at $80 is $854, against at least $387.33 on Semrush.

Ahrefs also raises the seat price on each tier, from $40 to $60 to $80 to $100. An upgrade taken for data therefore reprices every login you already have. That is the mechanism to model before a hire, not after one.

The fair counterweight is what the higher plan buys. Ahrefs Standard removes the per-user credit cap, and carries more than twice Lite's tracked keywords and four times its history. A team pushed up by the seat cap is not paying for nothing. It is paying for things it may not have asked for.

Ahrefs Lite gives each person 1,000 credits a month. Ahrefs' help centre says a credit is spent whenever you open a report, apply a filter or ask for more data. An afternoon of competitor research uses them quickly. Standard and above remove the cap for every active user, subject to fair use.

Semrush meters by the day instead. Its pricing FAQ gives SEO plan users 3,000 searches a day in the analytics reports, Pro+ 5,000 and Advanced 10,000. A search and a credit are not the same unit, so the numbers do not convert. The scale is still different: one allowance lasts a month, the other resets every day.

Ahrefs lets you run past its limits if you choose to. Pay-as-you-go is switched off by default. Switched on, extra Lite credits cost $50 per 500, and extra credits, crawl credits and API units all last three billing months. Semrush's API units work the other way and expire when the plan renews.

If more than one person will do research most days, I would price Ahrefs Standard from the start rather than Lite. The credit cap is the limit a research-heavy person meets first, and the seat charges on Lite grow with exactly that activity.

Ahrefs puts API v3 on Lite and above, and its direct API, MCP server and Ahrefs Connect all draw on one monthly allowance. A request costs 50 units or the per-row field cost times the rows returned, whichever is higher. Cached responses cost nothing.

The limit that binds below Enterprise is rows per request: 100 on Lite, 250 on Standard and 500 on Advanced. A 20,000-row backlink export is 200 calls on Lite and 40 on Advanced, at a default ceiling of 60 requests a minute.

Semrush lists API data integration only on Advanced, and its units are sold in packages with no public price. MCP access starts lower, on Starter at $165.17, which makes an AI assistant the cheaper way into Semrush data than a script.

So the practical split is simple. On Ahrefs, a small team can script against the link index for $108 a month. On Semrush, a script is a $455.67 decision followed by a sales conversation.

The shorthand that keeps coming up in r/bigseo is links on one side and keywords on the other. Practitioners there call Semrush's keyword tooling and clustering genuinely strong, and tolerate a gap in its backlink data. When a link has to be confirmed, they turn to Ahrefs.

An Ahrefs vs Semrush comparison that stops at that shorthand hides a plan detail. Ahrefs Lite shows at most 2,500 rows per report, against 30,000 on Standard and 75,000 on Advanced, and exports 500,000 rows a month. On Lite, a profile with tens of thousands of backlinks is read through filters, a slice at a time.

Semrush's advantage runs the other way. It is the wider suite. It sells all-channel competitor traffic estimates as the Traffic & Market toolkit, at $289 a month billed annually, separately from the SEO plans. Ahrefs estimates organic and paid search traffic, not the other channels.

So the shorthand is a fair starting point with a price attached. If link work is the job, budget for the Ahrefs tier whose row limit fits your largest profile. If the job is market research, budget for the Semrush toolkit rather than assuming the SEO plan covers it.

Semrush offers a one-time, 7-day money-back guarantee, and only on a first subscription of twelve months or more, or a first add-on. Its policy states that month-to-month subscriptions are not refundable. A 7-day free trial comes first, and it converts to a paid plan automatically unless you cancel.

Ahrefs says it does not issue refunds in general. A monthly subscription may be refunded if you have not used the service, and Ahrefs may decline if it sees material activity. There is no trial, and its FAQ says it never runs discounts. The free way in is Ahrefs Free, on a site you can verify.

That makes the safe way to evaluate each one different. Use Semrush's trial first, and before buying annually, check that your purchase counts as the first one the guarantee covers. Ahrefs has no equivalent, so pay for one month of Lite, use it hard, and treat that month as spent.

Both let you cancel at any time, with the plan running to the end of the paid period. Ahrefs drops you to Ahrefs Free when it ends. Semrush requires its cancellation form, submitted while you are logged in, and says a request made any other way may be denied.
