Keyword Planner

Keyword Planner is a free research tool within Google Ads that helps advertisers discover new keywords, estimate search volumes, forecast traffic, and plan budgets. It provides historical search data, competition levels, and suggested bid ranges to inform keyword selection and campaign structure decisions.

Key Takeaways

• Free tool available in Google Ads under Tools > Planning > Keyword Planner
• Two modes: discover new keywords and get search volume forecasts
• Provides monthly search volume ranges, competition level, and bid estimates
• Forecasts clicks, impressions, cost, and conversions based on your bid and budget
• Data accuracy improves for accounts with active spending (vs. accounts with no spend history)

What Is Keyword Planner

Keyword Planner is Google’s official keyword research tool, accessible to anyone with a Google Ads account. It serves two primary functions:

Function	Input	Output
Discover new keywords	Seed keywords, website URL, or product category	Keyword suggestions with volume, competition, bid ranges
Get search volume and forecasts	List of specific keywords	Traffic estimates, cost projections, conversion forecasts

Unlike third-party keyword tools, Keyword Planner draws directly from Google’s search data, making it the most authoritative source for Google-specific metrics. However, accounts without active ad spend receive volume data in broad ranges (e.g., “1K-10K”) rather than precise numbers.

How It Works

Discovering keywords:

1. Enter seed keywords, a landing page URL, or a product category
2. Set filters: location, language, date range, search networks
3. Review suggested keywords with metrics: average monthly searches, competition (Low/Medium/High), top-of-page bid ranges
4. Select relevant keywords and add them to a plan or directly to campaigns

Forecasting performance:

1. Enter or paste a list of keywords
2. Set a bid, daily budget, and location targeting
3. Review projected clicks, impressions, cost, CTR, and average CPC
4. Adjust bids and budgets to model different scenarios

Keyword Planner also groups keyword suggestions by theme, helping inform ad group structure. The competition metric reflects advertiser competition (how many advertisers bid on the term), not organic SEO difficulty.

Practical Example

A fitness equipment retailer researches keywords for a new campaign:

Keyword	Monthly Searches	Competition	Top Bid (Low)	Top Bid (High)
home gym equipment	33,100	High	$1.20	$3.50
adjustable dumbbells	22,200	High	$0.80	$2.40
resistance bands	40,500	Medium	$0.50	$1.60
squat rack for home	8,100	High	$1.50	$4.20

The forecast tool estimates that targeting all four keywords with a $2.00 max CPC and $100/day budget would generate approximately 1,200 clicks and 15,000 impressions per month at an average CPC of $1.75.

Why It Matters

Keyword Planner is the starting point for building Search campaigns with informed keyword selection and realistic budget expectations. It prevents two common mistakes: targeting keywords with insufficient volume to drive meaningful traffic, and underestimating the budget required to compete in high-competition segments. Combined with the Search Terms Report for ongoing optimization, Keyword Planner provides the research foundation while live data refines the strategy over time.
