Types of Advertising: Group by Billing Model, Not Platform

Listing advertising by platform produces dozens of entries and no decision value, because one platform can carry several billing models with very different economics. A more useful grouping is four types: pay per impression, pay per click, pay per partnership, and owned channels.

1. Cost Structures

The difference is what the money buys: display buys being seen, search buys intent, partnerships buy endorsement, owned channels buy relationship.

2. Display

Core metrics are cost per thousand impressions and creative click rate. At equal budget, creative quality matters more than channel choice.

The common error is judging display as a direct acquisition channel. Its job is to make later search and content easier to accept; standalone conversion rates often look poor.

It suits launches, regional coverage, and pre-event warm-up. Two to four weeks is a reasonable flight: shorter builds no recall, longer causes fatigue.

3. Search

Search buys existing demand, so term selection matters more than bidding. Terms divide into brand, category and question types.

Brand terms are cheap and bring no new customers. Category terms carry new demand. Question terms have low competition and suit content landing pages.

Search has a ceiling: term volume caps how much can be bought. Once the terms are exhausted, extra budget buys nothing more.

4. Content Partnerships

Creator collaborations, media placements, reviews. Pricing is fixed fee, performance share, or a mix.

Performance deals look low-risk but create attribution disputes: a user who saw the content and searched three days later — does that count?

Agree the attribution window and measurement before signing, and keep the content links live for at least six months.

5. Owned Channels

Newsletters, communities, messaging, on-site recommendations. This is not buying traffic; it is using what exists.

The cost is fixed labour with low marginal cost, and it suits businesses with a defined repurchase cycle. It brings no new customers but raises the value of each one, so the metric is repurchase rate rather than acquisition.

6. A Starter Mix

With limited budget, lead with search plus content, use display only around launches or campaigns, and start building owned channels from day one.

Judge the mix by two things: new customers arriving steadily, and existing customers returning steadily. Missing either means the mix harvests without storing.

Which type is cheapest?

Low cost per click does not mean low cost per customer. Calculate to the qualified lead level.

Can promotion work without ad budget?

Yes, through content and owned channels. Slower, but it accumulates assets.

Should we use a media agency?

Worth it at higher spend, where rebates and optimisation experience apply. At low spend, learning the data yourself is better value.
