Acquisition

Stage

The stretch where a new user first reaches the product through search, an ad or a link from a colleague — the first box in the growth funnel.

Why it exists

For a long time the answer to "how did marketing do" was a single number: visits. A report that ended at thirty thousand visitors last month gave nobody a way to tell whether that was good. How many of the thirty thousand signed up, and how many of those used the product even once, never appeared on the same sheet.

Meetings stalled in the same spot every time. Marketing reported thirty thousand visits, the CEO asked what happened to revenue, and with nothing connecting the two numbers the answer came back as a plan to run more ads. Months where traffic rose and revenue didn't repeated without anyone finding the leak.

The AARRR stages cut that single lump into five boxes and named each one. Acquisition is the name on the first box, and it covers only the moment someone reaches the product. What they did after arriving belongs to the next box. Split that way, a month where traffic doubled and revenue held flat can be traced through the ratios between boxes.

Splitting also made one thing obvious: the first box moves faster than the other four. Raise the ad budget and it goes up next week. That makes it the first place a demand for better numbers lands, and the easiest place to inflate.

What this stage looks like

What gets counted here is how many people reached the product and which road they took. Visits, app installs and new signups are the headline numbers, and a channel breakdown always sits beside them.

A total with no channel split is close to useless. An acquisition channel — the road a new user travels to reach you — can be search, paid ads, a link from a colleague or a community post, and each road converts differently into the next box. A thousand people from ads and a thousand from search routinely differ twofold in how many sign up. Write down only the combined two thousand and that gap disappears, while the budget stays where it performs worst.

The second trait is that money attaches directly to this box. What it costs to bring in one customer is the customer acquisition cost (CAC), and the sum happens here. Twenty thousand dollars of ads in a month that brings in forty paying teams comes to five hundred per team. When that figure runs above the lifetime value (LTV) the customer leaves behind, every sale deepens the hole, which is why this box is always read together with its cost.

The third is that channels answer at different speeds. Ads deliver people tomorrow if you raise the budget today, and stop the day you switch them off. Search engine optimization (SEO), the work of shaping a site and its writing so it surfaces in search results, behaves the other way around: a post written today may take three or four months to rank, and once it ranks, people keep arriving without further spend. Plans for this box usually mix a fast road with a slow one.

What moves you to the next one

The condition for moving on is that an arriving user experiences what the product is good for at least once. That box is the activation stage, and at Pagedeck the marker is saving a first document.

The reading is done on ratios between boxes, not on headcounts. Pagedeck's last quarter ran ten thousand visits, twelve hundred signups and five hundred forty first saves — twelve percent from visit to signup, forty-five percent from signup to first save. Hold those two and grow visits to fifteen thousand and acquisition has done its job. Grow visits while the ratios fall and what grew was traffic that landed nowhere.

One month went exactly that way. Ravi raised the banner budget, visits went from ten thousand to eighteen thousand, and signup conversion dropped from twelve percent to six. Signups fell from 1,200 to 1,080 while the ad spend doubled, because the ads reached people passing by rather than people looking for the product.

So the target for this box is set on people who arrive in the next box, not on visits. Aim at visits and the channel that brings anyone wins; aim at signups or first use and the channel carrying people who need the product wins.

How it sounds at work

"Acquisition is up this month but activation conversion dropped six points."

Traffic grew and the number of people actually trying the product didn't, so the newly added channel is the first suspect.

"Can we set the acquisition target on signups instead of visits?"

A request to stop counting traffic that never reaches the next box.

"Cheap per head on this channel, but nothing holds up behind it."

Bringing someone in costs little, and those people don't get as far as signing up or paying.

Pagedeck's weekly metrics meeting opens with this box laid out by channel. Ravi reads visits, signup conversion and cost per head for each road, and Mia lines them up against the next column. Last week a community post brought only 380 people but converted at 34 percent, while 6,200 came through banner ads at 4 percent.

The conclusion wasn't to move the banner budget into community. Community tops out around 400 a week, so the money wouldn't buy the same people. They decided instead to rewrite the banner copy and its landing screen around whatever that 34 percent post was saying.

What people get wrong

Reading acquisition as a synonym for ad spend is the most common error, and a fair one given that any demand to raise the number turns into a budget conversation. But this box holds people who came through search, people who clicked a colleague's link, and people who followed a community post, and the older the product, the larger the share that arrived without paid spend. Lean only on ads and traffic collapses in the month the budget pauses, which is the point at which switching the ads off stops being an option. Both kinds need growing from the start.

The idea that growing this box is where growth begins misfires just as often. It comes first in the sequence, so it looks like the place to start. Yet if eight of every nine users are gone within a week of signing up, doubling the ad budget leaves roughly the same number of people four months later. It's pouring water into a bucket with a hole in it. Check that retention holds first, and work on whichever of the five boxes loses the largest share.
