Google Keyword Planner is Google's free keyword tool. It shows keyword ideas, search volume ranges and ad competition, and the data comes straight from Google. It was built for planning ad campaigns, though, not for SEO. If you copy its numbers into an editorial plan without checking them, you often end up planning around searches that look different in reality.
After reading, you can get access, pull keyword ideas from the Planner and judge which of its numbers are safe to use in an SEO plan.
Access: free, but with a Google Ads account
Keyword Planner is part of Google Ads. You find it in the Tools menu under Planning. Google requires you to complete your account setup, including billing information, before you can use features such as new keyword ideas. That is stated in the Google Ads help on Keyword Planner.
You do not need a running campaign. When you set up a new account, you can switch to Expert Mode and create the account without a campaign. That way nothing is charged and you still get the planning tools.
One limitation is worth knowing: many accounts do not see an exact search volume, only ranges such as 100 to 1K or 1K to 10K. Google does not officially document when exact values appear. In practice it mostly affects accounts with no or low ad spend. Ranges are fine for a rough idea, but usually not for choosing between similar keywords.
The two features
Keyword Planner has two entry points that work differently well for SEO.
Discover new keywords. You enter words that describe your offer or topic, or a website. Google then suggests related keywords. If you start with a website, Google looks for keywords that match the content of that page. This also works with a competitor's page.
Get search volume and forecasts. You paste an existing list or upload it as a CSV and get metrics for exactly those keywords. This is useful when you already have ideas and just need orders of magnitude.
For keyword research in an SEO context, the first entry point is usually more productive and the second is a quick plausibility check.
What the numbers mean
The columns look neutral, but they come from the advertising world. Here is how to read them.
Average monthly searches. Search volume is a twelve-month average by default. Google counts the keyword together with its close variants, such as singular and plural, and rounds the values. A seasonal keyword with one strong month and eleven weak ones looks more modest on average than it is. Check the monthly breakdown as well.
Competition. Low, medium or high describes how strongly advertisers compete for the keyword. It says nothing about how hard an organic ranking is. Metrics such as keyword difficulty are based on the actual search results for that.
Top of page bid. The range shows what advertisers have paid in the past for an ad at the top of the page. A high value can point to purchase-oriented searches. It does not prove that organic visitors convert just as well.
Forecasts. They estimate clicks, impressions and costs for an ad plan. Google refreshes them daily based on the last seven to ten days. For SEO they are not a traffic forecast.
Step by step to useful keyword ideas
- Set the market. Choose location and language to match your audience, for example the United States and English. Run separate checks for other English-speaking markets, because terms and volumes differ.
- Start with problems, not product names. Enter three to five terms that describe what your audience wants to achieve or solve. Product names alone mostly return brand and purchase terms.
- Use a website as a second entry point. Enter the URL of a strong page on the topic, a competitor's page works too. This surfaces terms you would not have thought of.
- Narrow the results. Use the filters to exclude brand names and to include keywords with specific words. Grouping by theme helps with a first sort.
- Check the monthly trend. Show the monthly values before you schedule seasonal topics.
- Export and document. Export the list as a CSV and note market, language and date. Without these details, an export is hard to interpret a few months later.
An example: from seed to shortlist
A company selling time tracking software starts with the seeds "track working hours", "timesheet" and "calculate overtime" and uses the website of a well-known advice portal as a second entry point. The Planner returns a few hundred suggestions. After excluding other brands and plain job searches, three groups remain: questions about legal requirements for time tracking, templates such as timesheets in Excel or PDF, and comparisons of time tracking apps.
The ranges look similar for all three groups. Only the search results reveal the differences. For the legal questions, government sites, law firms and news sites rank. For the templates, download pages rank. For the comparisons, review sites and vendors rank. That points to three different page types: a guide, a template page and a comparison page. A long list of individual articles would be the weaker answer.
The team does not decide which group comes first based on the largest range. What counts is where its own offer helps searchers most and where the current results look within reach.
Keyword Planner, Search Console and Google Trends
Google's three free tools answer different questions. Search Console shows queries your pages already appear for, with real clicks and impressions, but only for your own website. Google Trends shows relative interest over time and is useful for seasonality and comparisons, but it gives no absolute numbers. Keyword Planner estimates absolute search volumes, including for topics where you have no visibility yet.
Together they give a useful picture. Each tool on its own has blind spots, and none of them tells you how hard it will be to rank.
The limits for SEO
Keyword Planner is a good source of ideas. For SEO decisions, a few things are missing.
- Close variants are grouped. When singular and plural share one value, you cannot see that Google may show very different results for each.
- Rare queries are missing. According to Google, keywords with very low search volume are not discoverable. Specific long-tail keywords with a clear intent therefore often do not appear.
- Questions are underrepresented. If you want to know which questions searchers actually ask, the People Also Ask tool or autocomplete data usually give you more than the Planner.
- The results page is missing. The Planner does not show which pages currently rank or which format Google prefers. Whether a keyword calls for a guide, a comparison or a product page only becomes clear through a SERP analysis.
- Intent is not labeled. The Planner does not distinguish between informational, comparative and purchase-oriented searches. You have to determine the search intent yourself.
Turning Planner data into decisions
An export with a few hundred keywords is raw material, not an editorial plan. Before it turns into pages, a short, fixed routine pays off.
First, remove clearly irrelevant terms such as other brands or job searches. Then check which terms your existing pages already cover. Search Console shows which queries your pages already get impressions for. Group keywords that answer the same question into a content cluster instead of planning a separate page for every row. Only the remaining candidates deserve a close look at the search results.
In the Crawl Foundry keyword database you can import the Planner export for free, clean up duplicates and organize keywords into lists. For the shortlist you then request fresh metrics: exact search volume with monthly history, keyword difficulty, CPC and search intent. You see the cost before you confirm. That way you only pay for the keywords that make the shortlist, and the Planner's ranges turn into concrete values.
What to use Google Keyword Planner for and when you need more
For a first look at a new topic, Keyword Planner is ideal. It is free, uses Google's own wording and shows orders of magnitude. It is usually enough for a quick check of whether a term is searched at all.
It reaches its limits as soon as you need to prioritize between similar keywords, find rare queries or assess the competition in the organic results. Then you need exact values instead of ranges, data about the results page and a place where your chosen keywords stay available with source and date. The Planner remains a good source of ideas. The decision about which page to build needs more context.
Start by running one seed keyword through the Planner and noting which columns you can trust for SEO.
