Display network banner advertising

Banners in the Google Display Network and programmatic buying: audience targeting, placement exclusions, frequency capping and banner remarketing.
Project order

What running banner advertising involves

From campaign structure and a full set of creatives to weekly placement cleanup. The ad account and the exclusion lists stay yours.

Display Network targeting

In-market and custom segments built from search terms, topics and hand-picked placements. Each method runs in its own campaign so the report stays readable.

GDNAudiencesIn-market

Banner sets and responsive display ads

The full range of sizes, including vertical and mobile formats, plus asset sets for responsive display ads that fill non-standard slots.

FormatsAssetsDesign

Banner remarketing

Lists split by depth of engagement, separate messages for cart abandoners and category browsers, and exclusion of people who already bought.

RemarketingSegments

Placement exclusions

Weekly review of the placement report, exclusion lists held at account level, and filtering out apps and games.

PlacementsExclusions

Brand safety and frequency capping

Sensitive content categories switched off, impressions per user capped, and campaigns separated by placement type.

Programmatic buying

For inventory outside the Google network or direct deals with publishers. We bring in a DSP when the volume justifies it.

Our clients’ results

We build long-term partnerships — and the numbers speak for themselves: our average client relationship lasts 5 years, and our partners' financial results grow quarter after quarter.

How we work

A display campaign is not judged by clicks. We track the cost of an action after contact with the banner and report view-through separately, so nothing is credited to display that it did not earn.

Exclusions matter more than targeting

A precise segment is worthless if impressions land in apps where clicks are accidental. We clean the inventory first, then narrow the audience.

Frequency is always capped

The twentieth view of the same banner annoys rather than persuades. The cap goes in on day one and is revised against frequency data.

No borrowed conversions

View-through conversions are shown as a separate line, never merged with direct ones. Otherwise banners beat every other channel on paper.

Why banners need hands-on work

In search a campaign is held together by keywords; in display it is held together by the exclusion list. Google automation optimises bids, but it will happily spend the budget on mobile games and aggregator domains if nothing stops it. The value here is less in the launch than in what happens to the campaign every week afterwards.

01

The account and the lists stay yours

Ads run from your own Google Ads account. Remarketing audiences, accumulated exclusion lists and impression history remain with you whatever happens.

02

Design in-house

A complete set of sizes and creative refreshes do not depend on an external studio's queue. Testing a new message takes days, not a month.

03

Reporting with placements, not just reach

We show which sites served the impressions, what we switched off and why. An impression count without that list explains nothing.

How we launch display campaigns

Tags and segments first, then creatives, and only then budget. A campaign launched before remarketing is configured spends its first month blind.

01

Tags, segments and structure

We check the Google Ads tag and GA4, build remarketing lists by depth of engagement, and define which segments deserve their own campaign.

02

Banners and assets

We produce the full set of sizes for the main slots plus assets for responsive display ads. Designers are in-house, so a new batch does not queue behind a contractor.

03

Launch and placement cleanup

In the first weeks the campaign gathers impressions broadly while we read the placement report every week and extend the exclusion lists. Most wasted impressions are cut here.

04

Frequency, remarketing and scaling

We set the frequency cap from data rather than guesswork, split messaging by segment, and move budget into the combinations that convert.

Frequently asked questions about banner advertising

The questions that come up most often before a display campaign starts.

01

How many banners do we need to start?

At minimum one set of the core sizes: 300×250, 336×280, 728×90, 300×600, 160×600 and two mobile formats, plus assets for responsive display ads. After that we add message variants rather than more sizes.

02

Do banners generate enquiries or only impressions?

It depends on the niche and the stage. Banner remarketing converts reliably because those people have already seen you. Cold display in the GDN buys cheap reach, but it usually produces fewer direct enquiries than search, and that is normal.

03

Can we run responsive display ads only?

You can, and on a small budget it is a sensible start. But Google assembles the layout from your assets, so you control the look less. Brands with strict guidelines need static creatives.

04

Why do our banners appear in mobile games?

Because apps are part of the Display Network by default and clicks there are often accidental. They are excluded by placement type and app category, and we do that at launch rather than after the first invoice.

05

Can you guarantee our ads never appear next to unwanted content?

No. No tool gives a hundred per cent guarantee, because network inventory changes daily. We reduce the risk: content categories are excluded, sensitive brands run on whitelists, and the placement report is checked every week.

06

Do we need programmatic, or is the GDN enough?

The GDN is enough for most cases. Programmatic makes sense when specific publishers matter, when you need inventory outside the Google network, or when the buying volume justifies a separate platform contract. We will say plainly if that is not your situation.

07

Do you produce the creatives, or do we supply them?

We produce them — designers are in-house. We can also work with your artwork, in which case we handle adaptation to every size and the testing of variants.

08

How does this differ from the display advertising service overall?

This page covers the practical side: campaign setup in the Display Network, banners, placements and buying. Media planning, reach and frequency modelling and brand lift measurement belong to the display direction page, and video sits in the separate YouTube service.

Banner advertising in the Google Display Network

Banner advertising: the technical parts

Three settings decide a display campaign: targeting, the exclusion list and the frequency cap. Adcore has run display campaigns since 2014, so what follows is mechanics, not merits.

Targeting in the Display Network

The GDN covers partner sites, mobile apps, Gmail and Discover. We combine several targeting methods, and each segment runs in its own campaign — otherwise the report never shows what worked.

  • in-market and custom segments from search terms;
  • remarketing lists by depth of engagement;
  • similar segments from your customer list;
  • topics and keywords of the host page;
  • hand-picked placements: named publishers and sections.

Formats and responsive display ads

A working set covers 300×250, 336×280, 728×90, 300×600, 160×600 and the mobile 320×50 and 320×100; without vertical formats a campaign cannot see part of the inventory. Responsive display ads fill odd slots, but static creatives keep the brand looking right.

Banner remarketing

The cheapest part of any display buy. Lists split by depth: category view, product page, abandoned cart, already purchased. The last group is excluded, or budget goes to people who have paid.

Placement exclusions and brand safety

The weekly work in the GDN. Apps and games produce accidental clicks, aggregators impressions with no engagement, sensitive categories are switched off separately. Exclusion lists live at account level, not per campaign.

GDN or programmatic

Two ways to buy the same format — the choice depends on the placements you need and the volume.

Placement controlexclusion lists, placement reportwhitelists, pre-bid verification
Paymentper click or per thousand impressionsper thousand impressions, fee shown apart
When it fitsremarketing and reach in the nichenamed publishers or large volume

When not to order banners

With no analytics in place, start with measurement: a working segment cannot be told apart from luck. If you need enquiries tomorrow and cheaper than search, banners will not deliver — nobody in the GDN was looking for you. And for an audience of fifty companies in narrow B2B, network reach is money spent on the wrong people.

How this differs from our other services

Media planning, reach and frequency modelling and brand lift sit on the display direction page; video is the separate YouTube service. This page is the buying practice.
