Semrush at $139.95 a month: how many people does that cover?Semrushの月$139.95は、何人分の料金ですか

Verified 17 August 2026 · SaaS COMPASS2026.08.17 確認 ・ SaaS COMPASS

One. Semrush's help centre states: “By default, all Semrush plans come with one user seat.” The $139.95 quoted in comparison articles is the monthly price for a single person.

Sharing one login between two people is not permitted

The terms of service are explicit: “Each Authorized User must be a unique individual, and two or more individuals may not share a single Authorized User's Account.” One email address can be signed in at a time by default. Budget on the basis of one seat per person.

Only people who sign in under their own ID are billed; anyone who merely receives a PDF costs nothing. External agencies can be given a guest role — a non-account user granted access to specific assets — but whether a guest consumes a paid seat is not documented officially.

What does the second person add?

Pro (shown as “SEO” on the pricing page)$139.95$45$229.95$76.651.64× at three users. The total rises, but the cost per person falls by almost half
Guru$249.95$80$409.95$136.65The same 1.64× multiple as Pro. Only the absolute figure is larger
Business$499.95$100$699.95$233.32The extra seat is about one-fifth of the base price — the best value of the four. The first seat is the hurdle
Starter (AI visibility for the first user only)$199$45$289$96.33Seats cost the same as Pro. At 1.45×, the multiple is in fact the lowest
Starter (AI visibility for all three)$199$45 + $99$487$162.33What raises the bill is not headcount but how widely AI visibility is distributed

Three people on Pro comes to $139.95 + $45 × 2 = $229.95, or $229.95 ÷ 3 = $76.65 each. The formula is ($139.95 + $45 × (users − 1)) ÷ users, and it falls as headcount rises: $63.99 at five users, $54.50 at ten. What increases is the total, not the cost per person.

There is no headcount at which Pro's total overtakes Guru's. The gap is $110 + $35 × (users − 1) — $110 at one user, widening to $285 at six. The line that does matter is a different one: Pro at three seats, $229.95, is cheaper than a single Guru seat at $249.95, and the fourth seat at $274.95 passes it.

“Pro+” is not a higher grade of Pro

According to the help centre, Starter on the pricing page corresponds to Pro, Pro+ to Guru and Advanced to Business, each with AI visibility added — the ability to measure how often your brand comes up when people ask an AI. The names are not a guide to what each plan contains. The $59.05 gap between Starter at $199 and SEO (the Pro equivalent) at $139.95 buys AI visibility for one person; if you have no need to measure it, SEO is sufficient. Only when an additional user also needs AI visibility does $99 per person sit on top of the $45 seat.

Where does Pro run out?

Limit (monthly plans)ProGuruBusinessHow to read this
Websites to monitor (registration is by domain — a site address such as example.com; the official term is “websites to monitor”, shown in the interface as “Projects”)51540Your own site plus three or four competitors fills Pro. The moment you want a fifth, you are on Guru
Keywords to track (a keyword is a term typed into the search box; this is how many can be logged automatically each day)5001,5005,000A single small-business site typically works with 100–300 terms in practice, so Pro's 500 is enough. Combine terms with locations (“tax accountant Shibuya” × 20 districts) and you reach several thousand
Rows per report (the maximum a single analysis can return)10,00030,00050,000If the top 10,000 rows answer your question, Pro is unlikely to get in the way. This only bites when you export everything to CSV and analyse it yourself
API (machine access for pulling data into other tools)NoNoYesRelevant only if you run an internal data platform processing tens of thousands of rows a month

In practice there is one line to read: whether 500 tracked keywords are enough. If they are, Pro; if not, Guru. Most businesses will fit inside Pro.

What actually leaves your account when you sign

Monthly billing is $139.95, or $139.95 × 12 = $1,679.40 over a year. Annual billing is displayed as $117.33 a month, but the help centre states plainly that annual is a prepayment for a full year, not twelve instalments. What is debited in one go is $117.33 × 12 = $1,407.96 (roughly ¥210,000 at ¥150 to the dollar). The difference is $271.44, a discount of 1 − 117.33 ÷ 139.95 = 16.2%. Annual pricing for additional users is not documented officially, so ask for a written quote covering the full headcount.

The seven-day trial bills you if you leave it alone

There is a seven-day free trial. Whether a card is required is not stated on the help, pricing or legal pages; only the FAQ on the official blog says “if you want to start the 7-day free trial, you'll need to enter credit card details.” Sign up expecting to be asked for a card.

Unless you cancel beforehand, the first payment is charged automatically when the trial ends. The refund policy also states: “Refunds are not available for month-to-month subscriptions.” The day the count starts is not documented officially, so make your decision by day five at the latest.

To try it without handing over a card, use the free account — the pricing page says “No credit card required”. The main tools (including backlink research, backlinks being external links pointing to your site from others) are limited to 10 queries a day, position tracking to 10 keywords, and site audit — the crawl that lists what needs fixing — to 100 pages a month.

How many people can Semrush cover before it stops being cheap?

Q1 How many people will open Semrush and work with the numbers themselves? (Do not count people who only receive reports.) 1 person 2–3 people 4 or more One Pro seat $139.95 / mo One Pro seat each $184.95–$229.95 / mo Check the fourth person really analyses. Viewers need no seat — send them a PDF Q2 Do you need to track more than 500 keywords daily? Yes Guru from $249.95 / mo No Q3 Do you need to measure how your brand appears in AI search such as ChatGPT? Yes Starter $199 / mo ($59.05 above SEO) No SEO, the Pro equivalent ($139.95 / mo) Once the plan is set Q4 Are you confident you will keep using it? Yes Annual $1,407.96 up front refunds only by written request within 7 days of the first order No Three months monthly ($419.85, non-refundable) All amounts in USD, excluding tax: monthly totals including one seat per person

The axis is not price but headcount — how many people open the screen and work with the numbers themselves. At one person or at two or three, the answer is Pro ($139.95 each, falling to $76.65; annual is $1,407.96 up front). Before adding a fourth, establish whether that person analyses or merely reads. Once tracked keywords pass 500, it is Guru regardless of headcount. If you are undecided, three months of monthly billing is $419.85 — money that does not come back.

Who should not sign

  • A site launched so recently it has fewer than ten articles. There is almost nothing for the tool to work with
  • A business fed mainly by repeat custom and referrals. Better rankings are unlikely to translate into revenue
  • Anyone whose SEO is handled by an agency. Ask first which tool they use and whether they can share the reports
  • An organisation where five or more people read the numbers but only one analyses them. One seat plus a PDF beats five seats

利用規約に「各認証ユーザーは固有の個人でなければならず、2名以上が単一の認証ユーザーアカウントを共有することはできません」(原文:Each Authorized User must be a unique individual, and two or more individuals may not share a single Authorized User's Account.)とあります。同時にログインできるメールアドレスも既定で1つです。人数分の席を買う前提で見積もってください。

「Pro+」はProの上位版ではありません

公式ヘルプによると、料金ページのStarterはPro相当、Pro+はGuru相当、AdvancedはBusiness相当に、AI可視性(AIに質問したとき自社名がどれくらい出てくるかを測る機能)を足した構成です。名前から中身を推測すると、ずれます。Starter $199 とSEO=Pro相当 $139.95 の差 $59.05 はAI可視性1人分の対価で、測る必要がなければSEOで足ります。追加ユーザーにAI可視性を渡す場合だけ、1人$99が席代$45に上乗せされます。

Proの上限は、どこで足りなくなりますか

上限(月払プラン)ProGuruBusinessこの数字の読み方
監視サイト数(ドメイン=example.com のようなサイトの住所を単位に登録する枠。公式表記は websites to monitor、画面上は「プロジェクト」)51540自社1+競合3〜4でProは埋まります。5社目を足したくなったらGuruです
追跡キーワード数(キーワード=検索窓に打ち込まれる語。その順位を日々自動記録する語数)5001,5005,000中小企業の1サイトなら実務で使うのは100〜300語程度で、Proの500で足ります。地域名の掛け合わせ(「渋谷 税理士」×20エリア)を追い始めると数千語に届きます

API(外部ツールに機械的に取り込む口)なしなしあり社内にデータ基盤があり、月次で数万行を自動処理する規模の話です

見るのは実質1行、追跡キーワードが500語で足りるかです。足りるならPro、足りないならGuru。大半の事業者はProで収まりそうです。

契約時に、実際いくら出ていきますか

月払は$139.95、12か月で $139.95×12=$1,679.40。年払の表示は月$117.33ですが、公式ヘルプは年払を1年分の前払いであって12か月の分割払いではないと明記しています。一度に引き落とされるのは $117.33×12=$1,407.96(1ドル150円換算で約21万円)。差は$271.44、割引率は 1−117.33÷139.95=16.2%です。追加ユーザーの年払価格は公式に確認できず、複数人分の見積もりは書面で出させてください。

7日間トライアルは、放っておくと課金されます

7日間の無料トライアルがあります。カード登録の要否はヘルプ・料金・法務の各ページに記載がなく、公式ブログのFAQにだけ「7日間の無料トライアルを開始したい場合は、クレジットカード情報の入力が必要です」(原文:if you want to start the 7-day free trial, you'll need to enter credit card details.)とありました。カードを求められる前提で申し込んでください。

事前に解約しない限り、終了時に初回の支払いが自動的に請求されます。返金ポリシーには「月払いのサブスクリプションには返金がありません」(原文:Refunds are not available for month-to-month subscriptions.)ともあります。起算日は公式に確認できなかったので、遅くとも5日目に決めてください。

カードを出さずに試すなら無料アカウントです(料金ページに「No credit card required」)。主要ツール(被リンク=他サイトから自社への外部リンクの調査など)は1日10回、順位追跡は10キーワード、サイト診断=巡回して直すべき箇所を一覧にする機能は月100ページまで。

何人までなら、Semrushは高くありませんか

軸は料金ではなく「自分で画面を開いて数字を触る人が何人か」です。1人でも2〜3人でもPro(1人あたり$139.95→$76.65/年払は初回一括$1,407.96)。4人目は、自分で分析するのか見るだけかを先に確認してください。追跡キーワードが500語を超えたら、人数に関係なくGuru。迷ったら月払3か月=$419.85で、これは返金対象外の戻らない額です。

契約しないほうがいい人

  • 記事が10本もない立ち上げ直後のサイト。ツールが返せるものがほとんどありません
  • 集客がリピートと紹介中心。順位を上げても売上に繋がりにくいはずです
  • SEOを代理店に任せている。先に「どのツールを使い、レポートを共有できるか」を聞いてください
  • 見る人が5人以上で、自分で分析するのは1人だけの組織。5席買うより1席+PDF配布で足ります
