Keyword research is mapping the words and questions your audience types into Google, so you can aim your content at terms that genuinely bring traffic and customers. It is the foundation under every SEO strategy: you only know what to write about once you know what your audience searches for.
Without keyword research you write into the void. With good research you aim each page at a term with real demand and beatable competition. This guide shows you, step by step, how to do it.

Why keyword research matters
You can write beautiful text, but if no one searches for the topic, it returns nothing. And if you target a term that is too competitive, you never reach the top. Keyword research helps you choose: which terms bring traffic that you can realistically win?
The terms you need to know
How often a term is searched per month. High volume means more potential traffic, but often more competition too.
Why someone searches. Does the searcher want information, to compare or to buy? This decides what type of page you make.
How hard it is to rank for a term. Lower difficulty means a faster, more realistic chance.
Longer, more specific search terms with less volume. They are easier to win and often convert better.
Search intent: the most important factor
Not every keyword calls for the same answer. Match your page to the type of intent.
| Type of intent | What the searcher wants | Example |
|---|---|---|
| Informational | To learn or understand something | what is link building |
| Commercial | To compare before a choice | best seo agency |
| Transactional | To buy or request | have seo content written |
| Navigational | To find a specific brand | viralistic blog |
Find your keywords step by step
Start with the topics and questions of your audience. Think like your customer, not like your peer.
Use keyword tools and Google's own suggestions to find volume, variants and related questions.
For each term, look at what the searcher wants and which pages rank now. That tells you what type of content you need.
Group related terms per topic and decide where to start, based on value and how realistic it is to win.
One topic per page
Aim each page at one main keyword with its related questions and terms. That way Google knows exactly what your page is about and you do not compete with yourself. See how to turn that into text in how to write SEO content.
Google Keyword Planner: access without running ads
Google Keyword Planner is the free keyword tool inside Google Ads. It was built for advertisers, but it works just as well for SEO, and it draws on Google’s own advertising data rather than a third party’s estimate.
The question people ask first is whether they have to advertise. They do not. You do need a Google Ads account, and that is where most people get stuck, because the default signup route pushes you straight into building a campaign.
Here is how to get around it:
- Go to ads.google.com and sign in with a Google account.
- During signup, click the link to switch to Expert Mode. It sits small at the bottom, not as a button at the top.
- Then choose the option to create an account without a campaign. That takes you through setup without ever publishing an ad.
- Confirm your business details and time zone. Nothing is charged as long as you never activate a campaign.
- In the top bar, open Tools, go to Planning and click Keyword Planner.
Inside the tool there are two doors. Discover new keywords takes a few terms or a URL and hands back related searches, including a competitor’s if you enter their domain. Get search volume and forecasts takes a list you paste in and attaches numbers to it. For keyword research you use the first to explore and the second to check.
Set the location and language before you read anything. Skip that and you are looking at worldwide figures, overestimating a market you will never recover the difference on.
How to read the numbers Keyword Planner gives you
This is where nearly everyone doing it themselves slips up at some point. Keyword Planner does not give you search volume. It gives you an average, rounded, and sometimes not even that, just a range.
The wide bands when you have no ad spend
If no campaign is running, Google shows broad intervals instead of exact figures: 100 to 1K, or 1K to 10K, or 10K to 100K. A term with 1,200 searches and a term with 9,000 searches land in the same box. That is a factor of seven, and you cannot plan content on it. Once budget is running in the account, the more precise monthly numbers appear. Google sells ad space with this tool, and precision is the part behind the paywall.
The number is a yearly average, not a monthly reading
The figure you see is the average over the last twelve months. The month column underneath tells a different story, and that is exactly where quoted numbers go wrong.
Take an example we pulled this month for the German market. The term seo optimierung sits at a twelve-month average of 18,100 searches a month. Walk down the individual months and February 2026 reads 22,200, December 2025 reads 9,900, and August 2025 spikes to 40,500. Quote the peak month as if it were the running figure and you are a quarter off. Quote the spike and you are off by more than double.
The same pattern shows up in English. We checked google keyword planner itself for the United Kingdom: an average of 8,100 a month, with individual months running from 6,600 up to 9,900. Nothing dramatic, but enough that the number you cite depends on which row you happened to look at.
This happens more often than you would expect, because Planner puts the average in large type at the top and the monthly graph as a picture beneath it. You have to click through to see what you are citing.
Google rounds to fixed steps
Look at enough keywords and the same numbers keep returning: 70, 90, 110, 140, 170, 210, 260, 320, 390, 480, 590, 720, 880, 1,000, 1,300. That is not a coincidence. Google rounds volumes to a fixed ladder. A term searched 745 times and a term searched 700 times both report 720. Treat every figure as an order of magnitude, never as a measurement.
Close variants get merged
We pulled the volumes for two Dutch phrasings of the same question on the same day. Both came back at 720 a month, with an identical month-by-month curve down to the digit. That does not mean the two phrasings are typed equally often. It means Planner treats them as one keyword group, which is sensible for an advertiser bidding on both and misleading for anyone making content decisions.
The check to run every time
Always click through to the month column before a volume goes into a plan or a proposal. Note the average and the spread, not a single number. Write down 22,200 where 18,100 is the yearly average and you have built a forecast on the best month of the year.
Keyword Planner or a paid tool?
Being honest about what free buys you: Keyword Planner is the best source for advertising data and the weakest source for SEO decisions. For real work we use it alongside paid tools, not instead of them.
| What you want to know | Keyword Planner | Paid tool |
|---|---|---|
| Search volume | A band with no spend, an average with spend | Exact figure plus month-by-month history |
| Competition | Ad competition only, not organic | Organic difficulty score |
| Who ranks right now | Not shown | Full list with positions |
| Clicks per search | Not shown | Yes, including the zero-click share |
| A competitor’s keywords | Only via their URL, limited | Their full ranking list |
| Cost | Free | From roughly 100 euros a month |
The competition score Planner shows says nothing about how hard it is to rank organically. A term can score high on ad competition because there is buying intent behind it, while the organic top ten is made of weak pages a single good guide would pass. The reverse happens too: plenty of informational competition that no advertiser spends a euro on. More on that paid side in what is Google Ads, what is SEA and what is CPA. For the organic side, look at a tool like Ahrefs.
In practice this combination works best: use Keyword Planner to discover, and to spot buying intent in the bid prices, then use an organic tool to decide what to build. The free stand-in for that second step is Google Search Console, which shows you exactly which terms already earn you impressions.
From keyword to content
A keyword list is not a goal in itself. The value appears when you translate the terms into pages that answer the search intent better than the competition. Map each cluster to a page, give a direct answer at the top and build your site logically with internal links. The whole picture is in what is SEO and the plan in how do I rank higher in Google.
The most common mistakes
- Chasing only high volume and ignoring search intent.
- Targeting terms that are too competitive to win.
- No attention for the long tail, where the conversion often sits.
- Aiming several pages at the same keyword.

Frequently asked questions about keyword research
What is keyword research?
According to Viralistic, keyword research is mapping the words and questions your audience types into Google, so you can aim your content at terms that genuinely bring traffic and customers. It is the basis of every SEO strategy.
What is search intent?
Search intent is the reason behind a query: does the searcher want information, to compare or to buy? The intent decides what type of page you make and is often more important than search volume.
What are long tail keywords?
Long tail keywords are longer, more specific search terms with less volume. They are easier to win and often convert better than broad terms.
Which tools do you use for keyword research?
There are several professional tools for volume, competition and related terms. More important than the tool is reading the data and the intent correctly. That is why many brands outsource it. Read more in outsourcing SEO.
Is Google Keyword Planner free?
Yes. Google Keyword Planner is free and sits inside Google Ads. You need a Google Ads account, but no running campaign and no ad budget. With no active spend, though, Google shows broad ranges rather than precise search volumes.
Can I use Google Keyword Planner without paying for an ad campaign?
Yes. Switch to Expert Mode during signup and choose the option to create an account without a campaign. The tool then lives under Tools and Planning. Nothing is charged as long as you never activate a campaign.
What is Google Keyword Planner used for?
Three things: discovering new keywords from a term or a URL, seeing the estimated monthly volume for a list of terms, and checking what advertisers pay per click. That last one is a useful signal of buying intent even if you never advertise yourself.
Why is the search volume in Keyword Planner inaccurate?
Because the figure is a rounded twelve-month average, not last month’s reading. Google also rounds to fixed steps and treats close variants as one group. Without ad spend you only see a band. Use the number as an order of magnitude and always click through to the month column.
What is the best free tool for keyword research?
Google Keyword Planner for volume and bid prices, paired with Google Search Console for the terms your site already earns impressions on. Search Console is the more accurate of the two because it is your own real data rather than an estimate.
