Tinh KPI Nguoc

Thu thap thong tin

Hoi user toi da 4 cau sau truoc khi bat dau:

1. Muc tieu la gi? (Doanh thu X trieu/thang? Hay ngan sach co san X trieu va muon biet duoc bao nhieu don?)
2. San pham / dich vu va gia ban? (Gia trung binh 1 don hang — AOV)
3. Nganh hang va kenh hien tai? (Nganh gi? Dang chay kenh nao? Co du lieu CPMess/CPL hien tai khong?)
4. Thoi gian chien dich? (1 thang? 3 thang? 6 thang? Co pha theo giai doan khong?)

2 huong tinh

Huong 1 — Tinh nguoc (Reverse): Tu doanh thu → Ngan sach

Dung khi: "Toi muon dat 200 trieu/thang — can bao nhieu tien ads?"

Doanh thu muc tieu
  / AOV (gia tri don trung binh)
  = SO DON CAN
  / Ti le Booking→Customer
  = SO BOOKING CAN
  / Ti le Lead→Booking
  = SO LEAD CAN
  / Ti le Mess→Lead
  = SO TIN NHAN CAN
  x CPMess
  = NGAN SACH ADS CAN

Huong 2 — Tinh xuoi (Forward): Tu ngan sach → Doanh thu

Dung khi: "Toi co 50 trieu — chay duoc bao nhieu don?"

Ngan sach
  / CPMess
  = SO TIN NHAN DU KIEN
  x Ti le Mess→Lead
  = SO LEAD DU KIEN
  x Ti le Lead→Booking
  = SO BOOKING DU KIEN
  x Ti le Booking→Customer
  = SO DON DU KIEN
  x AOV
  = DOANH THU DU KIEN

Unit economics — tinh TRUOC khi chay dong ads dau tien

Hai huong tinh o tren cho biet can bao nhieu tien. Phan nay cho biet bao nhieu la lo. Phai thuoc long truoc khi bat bat ky campaign nao.

Bo cong thuc day du

So don can          = Doanh thu muc tieu / AOV
So lead can         = So don can / Close rate (Lead -> Mua)
Max CPL (hoa von)   = (Doanh thu muc tieu x Gross margin %) / So lead can
CPL target (co lai) = Max CPL / 1.5
Break-even ROAS     = 1 / Gross margin %
Target ROAS         = Break-even ROAS x 1.5   (bien an toan)
Ngan sach ads can   = So lead can x CPL target
CAC                 = Tong chi phi ads / So khach hang moi
LTV                 = AOV x Tan suat mua/nam x So nam giu chan
LTV : CAC           = LTV / CAC          (nguong khoe: >= 3:1)
Payback period      = CAC / (Loi nhuan gop moi khach moi thang)

Gross margin = (Doanh thu - COGS) / Doanh thu. Khong biet gross margin thi khong tinh duoc gi ca — hoi user truoc.

Vi du so cu the — khoa hoc online

Gia dinh: AOV 3,000,000d · Gross margin 70% · Close rate Lead->Mua 30% · Muc tieu 300,000,000d/thang.

| Buoc | Cong thuc | Ket qua | |------|----------|---------| | So don can | 300,000,000 / 3,000,000 | 100 don | | So lead can | 100 / 30% | 334 lead | | Max CPL (hoa von) | (300,000,000 x 70%) / 334 | ~628,000d | | CPL target (co lai) | 628,000 / 1.5 | ~419,000d | | Break-even ROAS | 1 / 0.7 | 1.43x | | Target ROAS | 1.43 x 1.5 | 2.14x | | Ngan sach ads | 334 x 419,000 | ~140,000,000d | | Kiem tra lai | 300,000,000 / 140,000,000 | ROAS 2.14x — khop |

Doc so nay the nao: CPL cham 628K la hoa von, cham 419K la co lai. Neu thi truong dang cho CPL 700K → khong chay, phai sua offer, sua AOV, hoac sua gross margin truoc.

LTV : CAC — quyet dinh co duoc scale khong

| Ti le LTV:CAC | Y nghia | Hanh dong | |--------------|---------|----------| | < 1:1 | Lo tren moi khach hang | DUNG scale. Sua san pham hoac gia truoc | | 1:1 - 3:1 | Hoa von den kha thi | Toi uu conversion, tang AOV — chua scale | | > 3:1 | Khoe — co the tang truong | Bat dau scale co kiem soat | | > 5:1 | Rat tot | Tang ngan sach ads manh |

Payback period (thoi gian hoan von CAC) nen < 6 thang voi SME Viet Nam. Payback dai hon = dong tien bi ket, du ROAS dep van chet.

Nguong healthy tung buoc — canh bao va dung

Moi buoc trong pheu co nguong rieng. Kiem hang ngay khi ads dang chay; buoc nao vuot nguong DUNG thi xu ly buoc do truoc, khong do them tien.

| Chi so | Khoe | Canh bao | DUNG | Hanh dong khi cham nguong dung | |--------|------|---------|------|-------------------------------| | CPL / CPMess | <= target | > 1.5x target | > 2x target | Pause adset, chay 21-audit-ads-performance | | ROAS | >= Target ROAS | < Break-even x 0.8 | < Break-even | Review offer va gia truoc khi doi creative | | CTR (Meta) | >= 1.5% | < 0.8% | < 0.5% | Thay creative — van de o hook, khong phai o target | | Frequency | < 2.0 | 2.0 - 2.5 | > 3.0 | Thay creative va mo rong tep | | Mess -> Lead | >= benchmark nganh | thap hon benchmark 15% | thap hon benchmark 30% | Van de o sale/tu van, khong phai o ads | | Lead -> Booking | 60-75% | 40-60% | < 40% | Sua quy trinh follow-up, toc do reply | | Booking -> Customer | 40-55% | 25-40% | < 25% | Van de o trai nghiem va gia, khong phai o marketing |

Luat doc nguong: khi nhieu buoc cung do, sua buoc gan tien nhat truoc (Booking->Customer), roi lui dan ve dau pheu. Sua CPL truoc khi sua close rate la dot tien nhanh hon.
