Targeted Advertising: What It Is and How to Improve It
By Multivariate TeamNovember 7, 2026Paid Ads
Targeted advertising shows ads to people chosen by their context, interests, behaviour, or relationship with your business, instead of to everyone. Done well, it cuts wasted spend. Done badly, it shrinks your reach and annoys the people you most want to win. Here is how the main types work and how to improve results.

What is targeted advertising?
Targeted advertising means choosing who sees an ad based on information about them or about the moment they are in. A search ad for running shoes shown to someone typing running shoes is targeted. So is an Instagram ad for a project tool shown to people who visited its pricing page last week.
The opposite is broad advertising, such as a billboard or a TV spot, where everyone in the audience sees the same message. Most digital campaigns sit somewhere in between, and modern ad platforms increasingly push towards broad targeting with automated optimisation.
The main types of ad targeting, with examples
Contextual targeting
Ads match the content being viewed. Example: a camping stove ad on an article about hiking routes.
Keyword or search targeting
Ads match what someone searches for. Example: a Google Ads campaign on emergency plumber near me.
Demographic targeting
Ads are limited by age range, language, or similar attributes the platform allows. Example: a student banking offer restricted to younger age groups.
Geographic targeting
Ads are limited by country, city, or radius. Example: a restaurant targeting a few kilometres around its location.
Interest and behavioural targeting
The platform groups people by inferred interests or past activity. Example: a fitness app targeting people interested in running.
Retargeting
Ads reach people who already visited your site or app. Example: a reminder ad to someone who abandoned a basket.
Customer list targeting
You upload hashed customer details to reach existing customers or exclude them. Example: excluding current subscribers from an acquisition campaign.
Lookalike or similar audiences
The platform finds new people who resemble a seed list. Example: finding new buyers based on your best customers.
Targeted advertising on social media
Social platforms such as Meta, TikTok, LinkedIn, and Pinterest are where most people meet targeted ads. Each offers its own mix of interest, demographic, and custom audiences. LinkedIn stands out for professional attributes such as job function and company size, which is why B2B teams use it despite higher costs.
In recent years these platforms have moved away from granular manual targeting. Several interest options have been removed or merged, and automated campaign types encourage advertisers to target broadly and let the algorithm find buyers. In that setup, your creative and your conversion signal do more targeting work than your audience settings.
How to improve targeted advertising
These changes usually improve results more than adding narrower audiences.
Send better conversion signals
Optimise for the event that matters, such as a qualified lead or a purchase, not a page view. Send it server-side through conversion APIs so fewer are lost.
Use first-party audiences
Customer lists, site visitors, and app users are your most accurate audiences. Keep them fresh and segmented by value.
Exclude as carefully as you include
Remove existing customers from acquisition campaigns and recent buyers from retargeting.
Let creative do the targeting
Different messages attract different people. Test distinct angles for distinct segments instead of one ad for everyone.
Match the landing page
An ad aimed at a narrow audience should land on a page written for them, not the generic homepage.
Control frequency
Small retargeting audiences see the same ad too often. Cap frequency and rotate creative.
Test incrementality
Run holdout tests to see how many conversions the targeting actually created, rather than claimed.
Measure targeting by the right metric
Narrow targeting often shows a lower cost per conversion in the platform report, because it reaches people who would have bought anyway. That looks like efficiency, but much of it is not new demand.
Judge targeting by incremental results: new customers, revenue from people who were not already on your list, and lift compared with a control group. Track blended cost per acquisition across all channels, not just the platform's own attribution.
Privacy, consent, and ethics
Targeted advertising relies on personal data, so privacy rules apply. Depending on where your audience lives, you may need consent before using cookies or device identifiers for advertising, and you must honour opt-outs. Platforms also restrict targeting for sensitive categories such as health, finances, housing, and employment.
Beyond legal minimums, avoid targeting that would surprise or upset people if they saw why they were chosen. Contextual and first-party approaches tend to hold up best under both regulation and public expectation.
Targeted advertising FAQ
What is targeted advertising in simple terms?
Showing ads to a chosen group of people, or in a chosen context, instead of to everyone.
Is targeted advertising legal?
Yes, but it is regulated. Rules on consent, personal data, and sensitive categories vary by country and platform.
Does narrower targeting always perform better?
No. Very narrow audiences raise costs and limit learning. Many platforms now perform better with broader targeting and strong conversion data.
What is the difference between contextual and behavioural targeting?
Contextual uses the content of the page or search. Behavioural uses what the person did before.
