What is vanity metrics

Also known as: vanity numbers

Definition

Vanity metrics are numbers that look impressive, like followers, views or total sign ups, but do not tell you what to do next or whether sales are growing.

Why it matters

Vanity numbers are the easiest to find in any dashboard, so they are the easiest to steer by.

Common mistakes

Boosting the post with the most views instead of the post that brought the most bookings.

Worked exampleIllustration

The reel week of a fictional pilates studio

A fictional neighbourhood pilates studio boosts one reel for ₪600 and gets two reports of the same week.

  1. Views

    The reel reached 40,000 views, up from 10,000 the week before, and brought 1,200 new followers.

    (40,000 − 10,000) ÷ 10,000 = +300%

  2. After the views

    The same week brought 18 WhatsApp messages, 4 booked trial classes and 1 new member.

  3. Report one

    Views up 300%.

  4. Report two

    The cost of one booked trial class from the boost.

    ₪600 ÷ 4 = ₪150

  5. Decision

    The owner compares the next reel by its cost per booked trial, not by its views.

The first number felt great. The second tells the owner whether to boost the next reel.

Vanity or actionable?

  • Reel views

  • Cost per booked trial class

  • Instagram followers

  • Booked trial classes

  • Members of the WhatsApp group

  • Customers who came back within 60 days

  • All time sign ups

  • Members who stayed 3 months

Nothing sorted yet. The test for each number: does it tell the owner what to do next?

The test from The Lean Startup: an actionable number shows cause and effect. The same views become useful once they sit next to the bookings from the same reel.

Definition

A vanity metric is a number that grows and feels like progress but points to no next step: followers, reel views, page likes, members of a WhatsApp group, all time sign ups. Eric Ries, writing in 2009, summed them up as good for feeling awesome, bad for action. Such numbers may still move together with sales, but on their own they cannot show which ad, post or change caused what. An actionable metric ties a cause to an effect: the cost of a booked visit from one post, the share of chats that became a booking, the share of customers who came back.

Why it matters

A reel with 40,000 views feels like a win even when it brought one customer, and a budget moved by that feeling goes to the wrong post. The same number becomes useful when it is read next to what it brought: views next to the bookings from the same reel, followers next to the chats they started.

Directly related: Traction, Conversion Rate, CAC.

Improvement tips

  • Next to every number you report, write the decision it would change. If it changes none, it is a vanity metric for that question.
  • Read views and followers next to what they brought: chats, booked visits and new customers from the same post.
  • For every post or ad you paid for, work out the cost of one booked visit.
  • Watch the share of customers who come back, not only how many ever signed up.

Common mistakes

  • Counting all time sign ups or WhatsApp group members as if they were customers.
  • Reporting a growing follower count as proof that the business is growing while bookings stay flat.
  • Throwing reach numbers away altogether, although read next to bookings they show which post drew the right people.

Traction

Traction is evidence in numbers that real customers keep paying for or using a product, not just likes, followers or visits to a website.

Conversion Rate

Conversion rate is the share of people who took the step you count, such as booking or buying, out of those who reached the stage before it, like clicks.

MarketingIntermediate

CAC

CAC (customer acquisition cost) is what you spend on marketing and sales to win one new customer: a period's spend divided by the new customers it brought.

MarketingIntermediate

CPA

CPA (cost per acquisition) is what you pay on average for one conversion you chose to count, such as a booking or a sale: spend divided by those conversions.

KPI

A KPI (key performance indicator) is one of the few numbers a business tracks against a target and a date to see whether it is on course.

Frequently asked questions

What are vanity metrics in plain words?
Numbers that make the business look good but do not tell you what to do next: followers, views, likes, WhatsApp group members, all time sign ups. They can grow while sales stay the same.
What are examples of vanity metrics for a small business?
Instagram followers, reel views, Facebook page likes, members of your WhatsApp group and all time sign ups. Next to each there is a number you can act on: chats that became a booked visit, the cost of one booked visit, and the share of customers who came back.
How do I test whether a number is a vanity metric?
Ask whether a change in it tells you what to do next. In The Lean Startup (2011) Eric Ries asks three things of a useful report: actionable, showing clear cause and effect, accessible, simple enough for everyone to read, and auditable, credible because it can be checked against real customers.
Are followers worthless, then?
No. A following shows who is interested and can make it easier to reach people. It turns into a vanity metric when it is read alone, as proof of sales. Read it next to the chats and bookings from the same period.
Why are vanity metrics so tempting?
They usually grow, they are easy to find in any dashboard, and they need no extra work. The numbers tied to money often need one more step: counting chats by hand, or matching bookings to the post that brought them.
What should I measure instead?
The numbers closest to money: the cost of one booked visit, the share of chats that became a booking, the customers who came back within two months, and the members who stayed three months. They are harder to count and easier to act on.
Can the same number be a vanity metric and a useful one?
Yes, it depends on the question. Reel views alone are vanity. Reel views next to the bookings from the same reel show which kind of video draws the people who book, and that is a decision.
My leads arrive on WhatsApp. How do I know which post brought them?
Ask in your first reply how they heard about you, and label the chat by source in WhatsApp Business or in a simple list. A weekly count by hand is enough for a small business.
Was a boosted post with many likes a success?
Only if it brought what you boosted it for. Divide the boost by the booked visits it brought: in the example above, ₪600 for 4 booked trials is ₪150 each. That number can be compared with your other ads, likes cannot.
How often should I look at the numbers?
Look at the actionable numbers once a week at a fixed time, and judge over a month. On small numbers one booking more or less moves a weekly count a lot.
Do I need an analyst to separate vanity metrics from real ones?
No. Anyone can ask of each number whether it is tied to bookings, sales or customers who stay. If it only shows attention, read it as a sign of interest, not as proof of success.
Where does the term come from?
Eric Ries wrote about vanity metrics against actionable metrics in a 2009 guest post on tim.blog, and returned to them in his book The Lean Startup (2011). The idea came from startups and fits any business that pays for attention.

After I finished a cosmetology course at a leading company, I was confused. I didn't know how to open a business, what to sell from home, or how to bring in clients. Since I reached out to Mobius, everything has changed. We built an organized plan with clear steps and no unnecessary risks. Today I see results, and I'm growing and developing every month.

When I finished a massage course, I imagined a different world. I found out it's a hard field, and financial stability isn't easy to find. When I came to Mobius, something changed. We started an organized process and built a business plan. Without Mobius? I probably would have given up. Today I believe in myself and in my own path.
