Ad Placements: Setup, Reporting and Exclusions by Platform

An ad placement is a location where an advertisement appears. Depending on the platform, it can mean a website, an app, a YouTube video or channel, or a social surface such as a feed, Story or Reel.

Separate three questions in your workflow: Where do you want ads to appear? Where did they actually appear? Where should they not appear? This guide explains the differences between platforms and how to make informed exclusion decisions.

Placements versus audience targeting

Audience targeting primarily concerns who you want to reach. Placements concern where an ad appears. Even the same prospective customer may behave differently while reading an information site and while watching a Reel on a smartphone.

Placement is only one part of performance. Evaluate it alongside audience, creative, landing page, bidding, budget and measurement settings.

How Google, LINE Yahoo and Meta use the term

LINE Yahoo's Japanese interface uses プレイスメント, while Meta may show 配置. Similar labels do not mean that every platform accepts the same URL targeting or exclusion rules.

Google Ads: review delivery and exclude placements

See where ads appeared

Under Campaigns, look for Insights and reports, then the report for when and where ads showed and its placement view. Select the relevant campaign and a consistent date range before reviewing sites, videos or other locations.

This report does not list every placement. Low-volume placements may be omitted, and it is not a billing-reconciliation report. See Google's Where ads showed report documentation for its scope and limitations.

Exclude locations where ads should not appear

Check the campaign's Audiences, keywords and content → Content → Exclusions controls and select the supported scope for a website, app or video. For exclusions that should apply across an account, also review Content suitability.

Removing a targeted placement is different from excluding it. Other targeting conditions can still allow ads to appear there. If your intention is to prevent delivery, confirm that an exclusion has been applied. Google's placement exclusion instructions explain the available controls.

Campaign types do not all support the same configuration. For Performance Max, Google's guidance points to account-level and manager-account exclusions. Check the Performance Max brand-suitability guide instead of assuming the same setup as a standard display campaign.

LINE Yahoo: apply placement lists to an ad group

For display advertising, organize websites or apps into placement lists, then apply those lists to the relevant ad group. The basic workflow is:

1. Identify the locations to include or exclude.
2. Create the appropriate placement list.
3. Open the target ad group's targeting settings.
4. Select the list and choose delivery or exclusion, then save.
5. Review destination reports and the relevant list's performance.

You do not need a new campaign solely to use placement targeting if an existing ad group is suitable. Consider a separate structure when you need to distinguish objectives, budgets or evaluation conditions.

See the official Japanese documentation for creating placement lists and placement targeting. List-level totals may differ from other report totals, so check the reporting definitions before summing results.

Meta: choose between Advantage+ and manual placements

Review the Placements section at ad-set level. Advantage+ placements lets the delivery system use eligible surfaces. Where manual placements are available, the advertiser selects the surfaces. Available choices depend on the campaign objective and configuration.

Manual selection does not automatically improve results. Consider it when you have a specific constraint, such as creative that works only on certain surfaces or a brand requirement. Meta's official Reels advertising guide explains placement selection and adapting creative to the surface.

For analysis, keep the date range and ad-set scope consistent and use the relevant placement or platform breakdown in Ads Manager. Preview vertical creative to check whether interface controls cover text or crop important information.

A decision process before excluding placements

1. Define the reason: Distinguish brand suitability from acquisition efficiency.
2. Validate measurement: Check for missing or duplicated conversions before interpreting performance.
3. Align conditions: Compare the same period and conversion definition, accounting for device and creative differences.
4. Check the evidence: Consider spend, accumulated conversions and conversion delay. A handful of clicks rarely establishes a reliable pattern.
5. Record and review: Log the excluded location, reason and date. Monitor conversion volume and delivery as well as cost per acquisition.

Do not exclude a placement simply because CTR is low

The figures below are hypothetical and use the same reporting period and conversion definition. They are not actual campaign results.

B has a lower CTR but produces more conversions at a lower CPA in this example. If acquisition is the objective, click propensity alone is insufficient. With few conversions, however, results can still change substantially; this table is not a universal rule for excluding live placements.

Avoid narrowing delivery too far

• Check whether an account-wide exclusion affects other campaigns.
• Distinguish a whole-domain exclusion from a specific page.
• Watch whether reducing automated delivery options lowers total conversions.
• Do not mistake a creative or landing-page problem for a placement problem.
• Periodically review whether old exclusion reasons remain relevant.

Placement management is about preserving useful delivery while identifying unsuitable locations and improvement opportunities. Use each platform's detailed reports for placement decisions and consistent periods and definitions when comparing overall results across platforms.

NeX-Ray can support data aggregation and reporting for supported advertising services. Review placement controls in each platform's own interface and combine that work with broader campaign comparison. If measurement needs attention, see our GA4 click-tracking guide.
