What Is Google Keyword Planner?

Google Keyword Planner is a free keyword research tool offered by Google Ads. It’s primarily built to help advertisers find keyword ideas and assess how keywords might perform when used in ad campaigns. But even if you're not running paid ads, it's also a popular resource among SEOs for identifying organic opportunities.

How It Works

• Enter a keyword or URL
• Receive related keyword suggestions
• View average monthly search volume
• Assess competition (low, medium, high)
• See suggested bid estimates for paid ads

The data comes directly from Google, which generally means it's as reliable as it gets. However, as we’ll discuss, there are a few limitations to be mindful of.

Why Marketers Use Google Keyword Planner

Google Keyword Planner has become a staple for marketers and business owners looking to boost their visibility online. Even though it's technically part of Google Ads, many use it purely for SEO purposes. Here’s why:

It’s Free. Seriously.

Lots of SEO tools come with a hefty price tag. With Google Keyword Planner, all you need is a free Google Ads account — no payment required. If you’re bootstrapping or managing a tight budget, it offers a cost-effective way to get access to valuable keyword insights.

Data Straight from the Source

You’re getting keyword data straight from Google, including:

• Monthly search volume - How many times users search for a specific keyword each month
• Competition level - A basic indicator of how many advertisers are bidding for that keyword
• Top of page bid range - Helps gauge how competitive and valuable the keyword is in the ad space

This makes the tool ideal for validating keyword ideas before investing time in content creation or money in paid ads.

Limitations of Google Keyword Planner

As great as it is, this wouldn’t be a balanced Google Keyword Planner review without pointing out its flaws. Knowing the downsides will help you understand when to use it—and when to turn to more advanced alternatives.

Data Granularity Is Limited

One of the most common complaints is that the search volume data is often shown as broad ranges. Instead of getting exact monthly searches, you might see something like “1K–10K.” That kind of estimate isn’t very actionable when you're trying to prioritize terms.

Skewed Toward Paid Search

Since the tool is built for Google Ads, its strength lies in paid strategies. Organic SEOs may find that:

• The "competition" metric is ad-focused, not telling you how competitive a term is in organic SERPs
• Missing important data like keyword difficulty scores or SERP analysis

That said, when paired with other SEO tools & resources, it can still add massive value.

Best Use Cases for Google Keyword Planner

Knowing how and when to use the tool is half the battle. Here's where Keyword Planner shines the brightest:

1. Starting from Scratch

If you're launching a new website or blog, Google Keyword Planner is perfect for generating seed keyword ideas. Just pop in a general term or a competitor’s URL, and you'll get dozens (if not hundreds) of keyword suggestions.

2. Local SEO Campaigns

It allows you to filter by location, helping you get keyword data tailored to a specific city, region, or country. This is gold for service-based businesses and professionals targeting local markets.

3. Validating Paid Keyword Ideas

Running Google Ads? Then this tool is practically built for you. Before you spend money on a campaign, you can:

• Check how expensive and competitive your keywords are
• Understand bidding projections
• Estimate visibility based on budget

4. Brainstorming Content Topics

Need ideas for blog posts or landing pages? Use keyword suggestions to come up with relevant content topics that align with what your audience is actually searching for.

Tips for Getting the Most Out of Google Keyword Planner

If you want to squeeze maximum value from the tool, here are a few underrated tips most people miss:

• Use filters: Refine results based on keyword competition, volume, or cost-per-click to find your sweet spot.
• Check by “exact match”: Toggle match types to see performance potentials under different keyword matching rules.
• Incorporate negative keywords: Especially helpful when looking at ad performance and eliminating irrelevant results.
• Explore seasonal trends: Use the historical data toggle to get a sense of keyword seasonality over 12-month spans.

Alternatives to Google Keyword Planner

If you hit a wall with GKP and need more insights, consider these popular alternatives:
