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
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?
| Plan (monthly billing, USD, excl. tax) | 1 user | Each extra user | 3 users, total | Per user at 3 | How to read this |
|---|---|---|---|---|---|
| Pro (shown as “SEO” on the pricing page) | $139.95 | $45 | $229.95 | $76.65 | 1.64× at three users. The total rises, but the cost per person falls by almost half |
| Guru | $249.95 | $80 | $409.95 | $136.65 | The same 1.64× multiple as Pro. Only the absolute figure is larger |
| Business | $499.95 | $100 | $699.95 | $233.32 | The 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 | $96.33 | Seats 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 | $162.33 | What 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) | Pro | Guru | Business | How 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”) | 5 | 15 | 40 | Your 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) | 500 | 1,500 | 5,000 | A 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) | 10,000 | 30,000 | 50,000 | If 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) | No | No | Yes | Relevant only if you run an internal data platform processing tens of thousands of rows a month |

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?
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

1人分です。公式ヘルプに「すべてのSemrushプランには、既定で1つのユーザー席が付いています」(原文:By default, all Semrush plans come with one user seat.)とあります。比較記事で見る$139.95は、1人で使う月額です。
1つのIDを2人で使う節約は、規約上できません
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。
課金されるのは自分のIDでログインする人だけで、PDFを受け取るだけの人は無料です。社外の代理店にはゲスト(特定の資産にだけアクセス権を与えたアカウント外の人)というロールがありますが、席を消費するかは公式に確認できませんでした。
2人目は、いくら足されますか
| プラン(月払・米ドル・税別) | 1人 | 追加1人 | 3人の合計 | 3人時の1人あたり | この数字の読み方 |
|---|---|---|---|---|---|
| Pro(料金ページ上の表示は「SEO」) | $139.95 | $45 | $229.95 | $76.65 | 3人で1.64倍。総額は上がるが、1人あたりは半分近くまで下がる |
| Guru | $249.95 | $80 | $409.95 | $136.65 | 倍率はProと同じ1.64倍。上がるのは絶対額だけ |
| Business | $499.95 | $100 | $699.95 | $233.32 | 追加席が本体の約1/5で最も割安。1人目の壁が高い |
| Starter(AI可視性は1人目だけ) | $199 | $45 | $289 | $96.33 | 席の値段はProと同額。1.45倍で倍率はむしろ最も低い |
| Starter(AI可視性を3人全員に) | $199 | $45+$99 | $487 | $162.33 | 高くなるのは人数ではなく、AI可視性の配り方 |

Pro を3人なら $139.95+$45×2=$229.95、1人あたりは $229.95÷3=$76.65。式は($139.95+$45×(人数−1))÷人数で、人数が増えるほど下がります(5人$63.99、10人$54.50)。上がるのは総額であって、効率ではありません。
ProとGuruの総額が逆転する人数はありません。差額は $110+$35×(人数−1) で、1人$110差、6人$285差と開きます。見る線は別で、Pro3席の$229.95はGuru1席の$249.95より安く、4席目の$274.95で追い抜きます。
「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) | Pro | Guru | Business | 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」) | 5 | 15 | 40 | 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) | 500 | 1,500 | 5,000 | 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 |
| 1レポートの取得上限(1回の分析で取り出せる最大行数) | 10,000 | 30,000 | 50,000 | 上位1万件を見れば足りる規模なら、Proで困る場面は少なそうです。効くのは全件をCSVに落として自前で分析する場合だけです |
| 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 |

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
