In Google Ads, what can you use the Display Planner tool for when planning display campaigns?

Introduction / Context:
The Display Planner in Google Ads, or similar planning tools in other platforms, helps advertisers design and scale campaigns on display networks. This question checks whether you know the main functions of such a planning tool. Understanding these capabilities is important for media planners who want to find new audiences, placements, and ideas for display advertising, including banner and rich media ads.

Given Data / Assumptions:
- The advertiser is planning campaigns on a display network using Google Ads or a similar platform.
- A planning tool is available to research where and how to show display ads.
- The options list several functions related to adding ads, researching keywords, and identifying placements.

Concept / Approach:
Display planning tools are designed to help advertisers discover new targeting opportunities, including keywords, interests, topics, and specific websites or apps where ads can appear. They often provide estimates of impressions and costs for given targeting combinations. In addition, they make it easier to build campaigns and ad groups by suggesting ideas and allowing advertisers to add ads and targeting directly into their account structure. Because these tools bring together research, planning, and campaign building, the correct answer will reflect multiple related uses rather than a single narrow task.

Step-by-Step Solution:
Step 1: Examine option A, which mentions adding ads through the planner, a typical workflow feature where approved ideas can be pushed into ad groups. Step 2: Examine option B, which refers to researching audience ideas, keywords, and related concepts for display targeting. Step 3: Examine option C, which describes planning where ads can appear across the display network based on those ideas and estimates. Step 4: Recognise that a display planning tool is intended to support all of these activities together, so option D, All of the above, correctly summarises its role.

Verification / Alternative check:
If you have used the Display Planner or its successors inside Google Ads, you will have seen that it can suggest placements and audience segments, show forecast data, and allow you to add selected ideas into your campaigns. Tutorials and help articles also describe the tool as an all in one research and planning environment for display campaigns. This confirms that the tool is not limited to only one of the listed tasks but supports all of them, matching option D.

Why Other Options Are Wrong:
Options A, B, and C are each partially correct, but each one by itself covers only one dimension of what the Display Planner can do. The question asks what you can use the tool for overall, and the most complete and accurate answer is that it supports all of the listed activities together. Therefore, choosing only A, B, or C would understate its capabilities and would not fully answer the question.

Common Pitfalls:
A common mistake is to think of planning tools as limited keyword research tools, ignoring their ability to suggest placements and directly integrate with campaign creation. Another pitfall is assuming that planning can happen only outside the ad platform, for example in spreadsheets, rather than using the integrated planner. To answer exam questions correctly, remember that tools like Display Planner are designed to streamline the full planning workflow, from idea generation to targeting and ad creation, which is why All of the above is the correct choice here.

Final Answer:
The correct choice is All of the above..
