Is Your Marketing Prospecting or Harvesting? Understanding Incremental Growth in 2026

One of the biggest conversations we're having with clients right now is the difference between creating demand and capturing demand.

Both are important.

The challenge is understanding how much of your advertising budget is allocated to each and whether your marketing activity is genuinely driving business growth.

As advertising platforms become increasingly automated and AI-driven, many businesses are finding it more difficult to understand where their sales are actually coming from.

Google Ads may report a strong return on ad spend.

Meta Ads may report increasing conversion volumes.

Email marketing may be generating revenue.

SMS campaigns may be performing well.

But there is one question that matters more than any platform metric:

Would those sales have happened anyway?

This is where the concept of prospecting versus harvesting becomes incredibly important.

What Is Prospecting?

Prospecting refers to marketing activity designed to introduce your business to people who have never heard of you before.

These are potential customers who are not actively searching for your brand but may have a need for your products or services.

Examples of prospecting activity include:

• Non-brand Google Ads campaigns

• Meta prospecting campaigns

• Demand Gen campaigns

• YouTube campaigns

• Display advertising

• Influencer marketing

• Content marketing

• SEO targeting non-branded search terms

The goal of prospecting is simple:

Generate new demand and acquire new customers.

Without prospecting, businesses can become overly reliant on existing customers and existing brand awareness.

What Is Harvesting?

Harvesting refers to marketing activity designed to capture demand that already exists.

These users already know your brand, products or services and are actively searching for you.

Examples include:

• Brand search campaigns

• Branded Shopping traffic

• Direct website traffic

• Email marketing to existing customers

• SMS marketing to existing customers

• Returning customer remarketing campaigns

Harvesting is not a bad thing.

In fact, it is an important part of a healthy marketing strategy.

The challenge occurs when businesses mistake harvesting activity for growth.

Why This Matters More Than Ever

Over the last few years, advertising platforms have become significantly more automated.

Performance Max campaigns, Smart Bidding, broad match keywords and AI-powered audience expansion have created enormous opportunities for advertisers.

However, they have also created new challenges.

One of the most common issues we see is brand traffic gradually creeping into campaigns without advertisers fully realising it.

This can lead to inflated performance metrics.

A campaign may report a strong ROAS while contributing very little incremental growth to the business.

The campaign appears successful because it is capturing customers who were already intending to purchase.

The Question Every Business Should Ask

When reviewing marketing performance, ask:

"Would this customer have purchased if the advertisement had not been shown?"

This question helps identify whether a campaign is generating incremental growth or simply capturing existing demand.

The answer is rarely black and white.

Some campaigns do both.

The important thing is understanding the balance.

EOFY Marketing Review Checklist

As we approach EOFY, we recommend reviewing the following areas:

1. Review Search Terms Reports

Review search terms across your Google Ads campaigns.

Identify how much traffic contains your brand name and determine whether this is intentional.

2. Understand Brand Allocation

There is no universal right or wrong percentage.

Some businesses may require significant brand protection.

Others may benefit from allocating more budget towards prospecting.

The key is ensuring the allocation is deliberate.

3. Review Performance Max Campaigns

Performance Max campaigns can be extremely effective, however advertisers should understand how brand traffic is contributing to overall results.

Review campaign performance regularly and ensure results align with broader business goals.

4. Understand Shopping Campaign Behaviour

Many advertisers focus on brand traffic within Search campaigns but forget about Shopping campaigns.

If brand exclusions are implemented, Shopping visibility may also be impacted.

Before making changes, understand what happens when users search for your brand and whether competitors are appearing.

5. Review New Versus Returning Customers

Review customer acquisition data through your primary source of truth.

This may include:

• Shopify

• WooCommerce

• GA4

• CRM platforms

• Ecommerce reporting tools

Understanding new versus returning customer trends provides valuable insight into incremental growth.

6. Review Overall Revenue

One of the most important reviews any business can conduct is comparing platform performance against overall business performance.

A strong ROAS is valuable.

Revenue growth is more valuable.

Profitability is even more important.

The Goal Is Incremental Growth

At AIR DIGITAL, we believe the ultimate goal of marketing is not simply to achieve a strong ROAS.

The goal is incremental growth.

Strong marketing should:

• Protect existing demand

• Generate new demand

• Acquire new customers

• Increase customer lifetime value

• Improve profitability

• Support long-term business growth

Marketing channels should never be reviewed in isolation.

Google Ads, Meta Ads, email marketing, SMS marketing, SEO and organic social media all contribute to the same objective.

Business growth.

The most successful businesses review this regularly, challenge assumptions and ensure their marketing strategy is aligned with broader commercial objectives.

Because at the end of the day, the metric that matters most is not clicks, impressions or ROAS.

It is incremental growth.
