Google Ads Planner: Performance Planner vs an AI Campaign Planner

Search for "Google Ads planner" and you get two unrelated things: Google's Performance Planner, a forecasting tool inside Google Ads, and a new category of AI campaign planners that draft campaigns from a brief. They answer different questions — "what happens to my existing campaigns if I change the budget?" versus "what should the campaign I have not built yet look like?" — and most small accounts end up wanting both. Here is what each does, where each stops, and how they fit together.

Performance Planner: forecasts for campaigns that already exist

Performance Planner lives in Google Ads under Tools. Google describes it as a way to create plans for advertising spend and see how changes to campaigns might affect key metrics. Its forecasts are refreshed daily and, in Google's words, are based on the last 7–10 days, adjusted for seasonality; the system also simulates relevant ad auctions and takes account of competitor activity and landing pages (About Performance Planner).

What you do with it: pick campaigns, set a planning period and a target (spend, conversions or conversion value), drag the spend up or down, and read the forecast conversions. It can suggest budget and bid changes for the same spend, and — since the plan can now be applied directly — you review the per-campaign suggestions, deselect any you want to leave alone, and confirm; the changes go live and can be undone from Bulk actions.

What it needs

Eligibility is the part that trips up small accounts. As of October 2026 the help page lists, for Search, Standard Shopping and Performance Max campaigns: no bid-strategy change in the last 10 days; at least 3 clicks; at least 10 impressions; at least 1 conversion or conversion value; spend greater than zero in the last 17 days; and, for portfolio strategies, a shared budget covering every campaign in the portfolio. Demand Gen and App campaigns have their own thresholds. Display and Video campaigns are no longer supported at all: "Effective March 9, 2026, Performance Planner no longer supports planning for Display and Video campaigns."

In plain terms: Performance Planner needs history. A brand-new campaign, a paused one, or one with no conversions yet gives it nothing to simulate. You can include such campaigns by typing in past cost and conversion figures by hand, but the forecast is then only as good as your typing.

What it does not do

• It does not write keywords, ads, ad groups or audiences.
• It does not know about Meta or any other platform.
• It does not explain why a campaign's cost per conversion moved; it projects the curve forward.

AI campaign planners: drafts for campaigns that do not exist yet

An AI campaign planner starts from a brief — what the business sells, the landing page, the goal, the budget, the locations, the verified selling points — and drafts the structure: campaigns, ad groups, keywords with match types, negative keywords, responsive search ads with the fifteen headlines and four descriptions, sitelinks, and for Meta the ad sets with locations, ages and interests and the ads with primary text, headline and call to action. A good one checks the draft against the platforms' limits (30-character headlines, 90-character descriptions) and exports it as a file Google Ads Editor and Ads Manager can import, so everything arrives paused for a human to review.

What it needs

A brief and a human. The planner can only use what the brief contains — it should never invent prices, claims or awards — and the output is a draft. Every line gets read before it goes live, and the import is done by the advertiser, not the tool.

What it does not do

• It does not forecast. It has no auction data and makes no promise about clicks or conversions.
• It does not replace Google Ads Editor or Ads Manager; it feeds them.
• It does not know your account history unless it is also given your reports — which is where a dashboard comes in.

Side by side

Using both in one month

1. New offer or new business: write the brief, let the AI planner draft the Search and Meta campaigns, read every line, import them paused, fix tracking, switch on.
2. After two to three weeks the campaigns meet Performance Planner's thresholds. Use it to see what the next budget step would likely do before you commit it.
3. Every week, keep your own numbers — cost per lead per campaign, this period against the last — from the exported reports, so that neither tool is the only thing you trust.

Our AI Ads Planner covers the planner side and the weekly numbers: a brief becomes Google Ads Editor and Ads Manager import files, and the imported reports become a dashboard with AI-written recommendations you approve one by one. For forecasts, Performance Planner inside your Google Ads account remains the right — and free — tool.

Frequently asked

Is Performance Planner accurate?

Google positions it as an estimate built from recent auctions and seasonality; it is most useful for short horizons and for comparing options rather than as a promise. Google itself recommends planning weekly rather than monthly or quarterly when markets are unstable.

Why can't I see my campaign in Performance Planner?

Usually one of the eligibility rules: a bid-strategy change in the last 10 days, fewer than 3 clicks or 1 conversion, no spend in the last 17 days, a Display or Video campaign, or a campaign in an experiment.

Can an AI planner forecast results?

Not honestly. It can draft what to run and explain why; the forecast needs auction data that only Google has.
