A free keyword generator turns one topic into a list of related search terms, so you are not guessing what to write about. But to find relevant SEO keywords, a list of ideas is only the start. You still need to check intent, compare options, and confirm demand before you commit to a page. This guide shows how to use a free keyword generator properly, how to choose terms for a blog post, and where its limits are.
What a Free Keyword Generator Does (Before You Find Relevant SEO Keywords) |
A keyword generator takes a seed topic, such as “sourdough starter”, and returns related keywords, associated terms, and long-tail phrases. It saves brainstorming time and shows wording you may not have considered.
What it usually does not give you is verified demand. Our own free keyword generator pulls related terms from a public language database and shows a relevance score for each one. That score tells you how close a term is to your seed topic. It is not search volume, keyword difficulty, or a ranking prediction. Treat the results as ideas to test, not proof that people search for them.
Keyword Types You Will See
| Keyword type | Meaning | Example |
|---|---|---|
| Primary keyword | The main topic one page targets | sourdough starter |
| Secondary keyword | A supporting phrase on the same topic | sourdough starter feeding schedule |
| Long-tail keyword | A longer, more specific phrase | how to revive a sourdough starter |
| Related term | A word closely linked to the topic | hydration, flour, fermentation |
| Question keyword | A search phrased as a question | why is my sourdough starter not rising |
You do not need to match every variation exactly. Google’s own SEO Starter Guide notes that people describe the same thing differently (for example “charcuterie” and “cheese board”) and that its language systems can understand how a page relates to many queries, even without the exact terms.
How to Find Relevant SEO Keywords, Step by Step
- Start with a clear seed topic. Use a phrase from your product, service, or planned page. A specific seed gives better ideas than a broad one.
- Set the niche and country. Our tool lets you pick both, and Germany and France are among the country options.
- Generate the list and remove what does not fit. Delete anything that does not match what your page can honestly cover.
- Group terms by meaning. Terms that one page can answer belong together. Terms that need a different page go on a separate list.
- Check search intent. Search the term on Google and look at what ranks: guides, product pages, tools, or comparisons.
- Check demand. Use Google Trends to compare up to five terms and see rising related queries. If your site already has impressions, the Queries tab in Search Console also shows real terms. Google also advises that you should not write about something just because it is trending.
- Choose one primary keyword and a few supporting terms per page.

Understand Search Intent to Choose Relevant SEO Keywords
Two pages can target similar words and still need different content. A person typing “how to feed a sourdough starter” wants steps, while a person typing “buy sourdough starter” wants a product. The table below shows likely intent. These are starting guesses, and the live results are the real evidence.
| Example keyword | Likely search intent | Suitable content type |
|---|---|---|
| how to feed a sourdough starter | Informational | Step-by-step guide |
| sourdough vs yeast bread | Informational / comparison | Comparison article |
| sourdough starter kit | Commercial investigation | Buying guide or comparison |
| buy sourdough starter | Transactional | Product page |
| sourdough bakery near me | Local | Local business page |

Example: Finding Relevant SEO Keywords for a Blog Post
Say you run a home-baking blog and enter “sourdough starter” as your seed topic. The generator returns a long list. You scan it and spot three promising ideas: “how to feed a sourdough starter”, “sourdough starter not rising”, and “sourdough starter kit”.
Next, you search each one. If the results show guides for the first two and shopping pages for the third, you have your answer. The first two can share one helpful article, while the kit needs a different page type.
You could then pick “how to feed a sourdough starter” as the primary keyword and use “sourdough starter feeding schedule” and “sourdough starter not rising” as supporting terms. Shape the structure with our Blog Outline Generator or this blog post outline template, then test headline options with the SEO Title Generator. (This example is illustrative. The keywords have no verified volume data.)
Is a Free Keyword Generator Enough to Find Relevant SEO Keywords?
For early ideas, yes. For final decisions, not on its own. A free generator helps you widen your list, but it rarely tells you how many people search a term or how hard it is to compete for. Combine it with a look at the live results, Google Trends, and Search Console once your page has data. Add a dedicated SEO tool if you need volume estimates.
Also keep expectations realistic. Google’s SEO Starter Guide says there are no secrets that automatically rank a site first, and that it is sensible to wait a few weeks to judge the effect of changes.
Relevant SEO Keywords for Different Countries and Languages
Wording changes between markets, so do not assume one list works everywhere. Google Trends explains that interest can differ by country and that each market should be analyzed separately. For German or French audiences, research the local-language phrase instead of translating word for word. For example, you might test “kostenloser Keyword Generator” or “générateur de mots-clés gratuit”, then check the local results to confirm they match what you offer.
FAQ
Is a free keyword generator accurate?
It is useful for ideas, but it is not a source of verified search volume. Confirm demand and intent before writing.
How many keywords should one blog post target?
There is no fixed number. Use one primary keyword and a few closely related terms. Google’s guidance says there is no magic word count, and excessive keyword repetition is against its spam policies.
What is a long-tail keyword?
A longer, more specific search phrase, such as “how to revive a sourdough starter”. These often show clearer intent than short, broad terms.
Do I need exact-match keywords in every heading?
No. Write naturally and cover the topic clearly. Google’s language systems can connect related wording.
