Top of funnel vs bottom of funnel: How they differ and how to balance your budget

A movie's opening weekend is won long before anyone buys a ticket. Studios spend months on trailers, press tours, and billboards so that by Friday night, people already want a seat. Then a ticketing app takes the payment. If you judged the whole campaign by where the transaction happened, you'd conclude the ticketing app was the best marketer in Hollywood. While we can all see that's not the situation, the app still matters since a brilliant trailer with nowhere to buy a ticket sells nothing.

That's the tension in top of funnel vs bottom of funnel marketing. One end creates the wanting, the other collects the payment, and most reporting only credits the collector. Your split between the two is one of the biggest budget calls your team makes each year, so it pays to know what each end contributes before you shift any ad spend.

Key takeaways

• Top of funnel marketing creates demand among people who don't know you yet, while bottom of funnel marketing captures demand from people who are ready to buy.
• Each end needs the other. Lower funnel campaigns run out of people to convert without fresh awareness, and awareness with nothing to capture it hands sales to competitors.
• Lower funnel marketing is easy to track, but it often takes credit for buyers who were already on their way.
• Upper funnel marketing often earns its revenue somewhere else, like branded search, direct traffic, Amazon, or a store shelf.
• No budget split works for every brand. The right balance depends on your existing demand, your product, and where you sell.
• A full funnel strategy holds up only when both ends are measured in the same unit: revenue.

Top of funnel vs bottom of funnel at a glance

The marketing funnel, sometimes called the conversion funnel, is a simple model of the buyer's journey from first hearing about a brand to the final purchase. Top of funnel (also called the upper funnel) covers the awareness stage, where you're sparking interest with a broad audience. Bottom of funnel (the lower funnel) covers the decision stage, where potential customers become paying customers. Here's how the two ends compare.

Where the middle of the funnel fits

The middle funnel, or consideration stage, sits between the two ends. People here are weighing options, so comparison pages, customer testimonials, and other social proof carry most of your content strategy. This stage matters most for brands with longer sales cycles, where lead generation and nurturing more qualified leads take up much of the customer journey.

Why a channel isn't a funnel stage

Most digital marketing guides sort channels into stages, with connected TV on top and search on the bottom, but that shortcut hides a lot. A campaign's stage comes from who it's aimed at and what it asks them to do. On Meta, social media ads shown to strangers are upper funnel marketing, while retargeting ads shown to cart abandoners are lower funnel marketing. Google Ads works the same way, with YouTube campaigns at one end and branded search at the other. That's why funnel marketing is best judged campaign by campaign rather than channel by channel.

Why each end of the funnel needs the other

The two ends—one creating demand, one capturing it—work more like a supply chain than like rivals. You can see it most clearly when a brand funds only one of them.

What happens when you only fund the bottom

Lower funnel efforts depend on a steady supply of people who already know you. Retargeting ads need site visitors, lookalike audiences need new customers to model from, and branded search needs people who know your name. Cut awareness spending, and all three pools start to shrink.

The delay is what makes this hard to catch. Timing varies by brand, but the pattern usually runs like this:

• Months one and two: Performance holds steady, since you're living off past awareness.
• Months three and four: Audiences shrink, costs climb, and seasonality gets the blame.
• Around month six: Customer acquisition cost has jumped, and the fix takes months since awareness is slow to rebuild.

What happens when you only fund the top

The reverse mistake costs just as much. Your upper funnel campaign teaches potential customers about a problem and a category, and when they're ready to buy, they go searching. If a competitor's ad is the one waiting for them, you paid for the education and they collected the sale. Those lost sales never appear in a report, which makes top-heavy spending easy to miss. Lower funnel tactics like branded search and retargeting ads are how you stay present for the demand you created.

Four misconceptions about top of funnel and bottom of funnel marketing

Digital marketing forums argue about this split constantly, and a few claims come up in nearly every debate. Each one holds a little truth, which is what makes it risky.

"Bottom of funnel results are easy to attribute"

They're easy to track, which is a different thing. Someone who clicks a retargeting ad was often planning to buy before the ad appeared. The same goes for repeat purchases, since conversion campaigns often reach existing customers who would've come back anyway. A high conversion rate can make lower funnel marketing look stronger than it is.

"Top of funnel can't be measured"

Top of funnel marketing can be measured, though the usual signals stop short of dollars. (To be clear, upper funnel campaigns can also create conversions, but people often move to another platform to complete their purchase.) Branded search volume, organic traffic, and follower counts tell you whether awareness is growing. They don't tell you how much revenue it produced, so they rarely win a budget debate.

"Top of funnel only pays off in the long run"

Some of the payoff arrives within days, just through a different channel. Someone sees one of your paid ads on social, doesn't click, and searches your brand name that evening. The rest builds and fades over weeks or months, and every campaign has its own pace. "Long term" has no single definition, which is why a fixed reporting window shortchanges some campaigns.

"Awareness is just a way to get you to spend more"

It's a fair suspicion, since platforms and agencies do earn more when your budget goes up. The incentive runs in both directions, though, because platforms are just as happy to sell you conversion campaigns at premium prices. The safest move is to judge both ends with measurement that doesn't come from whoever's selling the media.

How to decide your split

No single ratio fits every digital marketing strategy, but a few factors will point you in a direction.

If you aren't sure which way you're leaning today, the warning signs below can help.

Signs you're too heavy at the bottom

These symptoms tend to show up together when lower funnel marketing is carrying too much of the budget:

• Retargeting audiences keep getting smaller.
• Ad frequency keeps rising, which means the same people see your ads again and again.
• Conversion optimization efforts, like new creative or landing page tests, deliver less each round.
• Branded search volume is flat or falling.

Signs you're too heavy at the top

Too much upper funnel spending has its own tells:

• Reach and brand lift look healthy, but paying customers don't follow.
• Competitors' Google Ads appear above yours on searches for your brand or category.
• First-time visitors hit a landing page with no clear next step, and your conversion rate shows it.
• You have few lower funnel tactics, such as email marketing or retargeting, to follow up with people who showed interest.

How to measure both ends on the same scale

The comparison table above shows the core problem. Upper funnel marketing reports reach, lower funnel marketing reports ROAS, and you can't weigh one against the other. The fix is to measure all of your marketing efforts in revenue, including revenue that lands outside a campaign's own reporting.

At Prescient, we call that outside revenue halo effects, meaning revenue a campaign drives indirectly through another channel. A video ad that leads to a branded search order, an Amazon purchase, or a sale at a retail store are all real examples. Top of funnel marketing produces the most halo effects, though any campaign can produce them, including retargeting.

The common measurement methods handle this in very different ways:

• Platform reporting: Each platform grades its own work and can't see sales that happen elsewhere.
• Multi-touch attribution: It follows clicks along the customer journey, so it misses ads people saw but didn't click and anything bought in a store.
• Incrementality tests: They're accurate for the campaign and time period tested, but they're a poor guide to the rest of your mix.
• Marketing mix modeling (MMM): It starts from total revenue across every sales channel and estimates what each campaign drove, halo effects included. (Again, to be clear, not all MMM providers can measure halo effects, but Prescient does.)

Measurement is only half of the job. The other half is knowing what's likely to happen when you scale a campaign or shift budget from one end to the other, ideally before you commit.

Where Prescient comes in

Prescient's MMM is built for omnichannel brands, so it measures every campaign across the funnel against revenue from your online store, Amazon, and retail storefronts. For each campaign, you see Modeled ROAS next to platform-reported ROAS, with halo effects—including retail halo effects—broken out. That puts awareness campaigns and conversion campaigns on the same scale, with measurable results for both.

When you're weighing a change to your split, Media Forecaster shows what's likely to happen if you scale a campaign or move budget between the two ends while your total stays the same. To see how your own top of funnel and bottom of funnel campaigns stack up, book a demo.

FAQs

What is the upper funnel, middle funnel, and lower funnel?

The upper funnel is where potential customers first learn a brand exists. The middle funnel is where they compare options, and the lower funnel is where they decide and buy. Together, the three stages make up the marketing funnel, which you'll also see called the conversion funnel. Each stage calls for different messaging and different key metrics, which is why a full funnel strategy plans for all three.

What is the bottom of a funnel called?

Bottom of funnel goes by several names, including BOFU, the lower funnel, the decision stage, and the conversion stage. In a B2B sales funnel, it's where teams focus on converting leads with pricing pages, product demos, and trials that let buyers try a service firsthand. For consumer brands, it's where lower funnel content like offers and reviews helps shoppers who've already narrowed their choices. Whatever the label, it covers the final stages of the buyer's journey.

What does the phrase "top of funnel" mean?

"Top of funnel" refers to the first stage of the buyer's journey, when people are just becoming aware of a problem, a category, or a brand. Marketing at the top of the funnel focuses on creating awareness and sparking interest rather than making a sales pitch. Typical top funnel tactics include video ads, social media posts, and content marketing that offers relevant content to people who aren't shopping yet.

What are the 5 stages of a sales funnel?

The most common five-stage sales funnel runs through awareness, interest, consideration, intent, and purchase. Some versions rename a stage or add loyalty after the sale, so you'll see variations. The top, middle, and bottom labels of the marketing funnel are a simpler way to group the same buyer's journey. Keep in mind that a real person rarely moves through the stages in a straight line, and user behavior often skips or repeats steps.

Is top of funnel or bottom of funnel more important?

Neither one works well alone. The top of the funnel creates the demand that lower funnel strategies depend on, and bottom of funnel marketing turns that demand into actual customers. Brands that only build awareness lose buyers to competitors, while brands that only chase conversions eventually run short of new people to convert. A full funnel approach that measures both ends in revenue is the most reliable path to more sales.

How much of your marketing budget should go to top of funnel?

No fixed percentage fits every brand. The right share depends on how much demand already exists for your product, how differentiated it is, how long people take to decide, and where you sell. A newer brand often needs more users to know it exists before lower funnel marketing has anyone to convert, while an established brand with untapped search demand may need the opposite. Revenue data for both ends is the best guide, since it shows whether a shift would increase conversions or just move credit around.
