To find keywords for blog posts, start with the queries you already rank for in Google Search Console, expand them with Google Keyword Planner and Semrush or Ahrefs, and check each one against the live search results. Then group the survivors into topic clusters and give every post exactly one primary keyword.
This guide is for editors, content leads, and marketing teams at publishers and subscription businesses who want posts that earn search traffic instead of guessing at topics. It walks through nine steps, a worked example for a magazine section, and the mistakes that quietly cost rankings.
What are keywords for blog posts?
Keywords for blog posts are the search terms and phrases people type into Google when they want an answer, an idea, or a solution a blog can provide. A post targeting "how to end a blog post" is built around the exact words a reader uses, not a broad topic label like "blogging."
Used well, keywords decide what you write, how you frame the angle, and which reader need the post has to satisfy. They shape headings, internal links, the meta description, and how deep the explanation goes. They also give editorial, sales, and lifecycle marketing a shared plan, which matters when content has to support a long buying journey.
Many teams still pick topics by brainstorming, by copying competitor headlines, or by pulling a long list from a tool without filtering it. That approach produces posts that sound generic, miss the real intent, or compete with each other for the same query. A repeatable keyword process fixes all three problems.
How to find keywords for blog posts in 9 steps
The steps below run from free first-party data to paid tools and then to planning. You can stop after step 5 with a usable shortlist, but steps 6 through 9 are what keep a blog from cannibalizing itself as it grows.
1. Mine Google Search Console for queries you already rank for
Open the Performance report in Google Search Console, set the date range to the last 3 months, and sort queries by impressions. Look for queries with high impressions, a low click-through rate, and an average position between roughly 8 and 30. Those are topics Google already associates with your site but where no page answers the query well.
Click into a query and open the Pages tab to see which URL is ranking. If the ranking page only mentions the topic in passing, that query is a strong candidate for a dedicated post. This is the cheapest keyword research you will ever do, because the demand is already proven on your own domain.
2. Collect questions from readers, sales, and support
Before opening a keyword tool, list the questions your audience already asks. Support tickets, sales call notes, onboarding conversations, newsletter replies, and comment threads all reveal the exact wording people use. These sources often produce stronger blog subject ideas than a tool alone, because they show what readers are actually trying to solve.
Write each question down in the reader's words, not yours. "How do I cancel my print subscription but keep digital" is a better seed than "subscription management."
3. Expand seeds with Google Keyword Planner
Google Keyword Planner is free inside a Google Ads account. Paste in your seeds under "Discover new keywords" and it returns related terms with monthly search ranges. Without active ad spend, the volumes appear as broad ranges such as 100 to 1K, which is fine for ranking ideas against each other.
Export the list and delete anything off-topic. You are looking for variations in wording, not exact counts.
4. Check seasonality and direction with Google Trends
Google Trends shows relative interest on a 0 to 100 scale, not absolute volume. Use it to compare two phrasings of the same idea and to spot seasonal peaks. A recipe section, for example, will see predictable spikes around holidays, so those posts need to be live and indexed weeks before the peak.
Trends also tells you whether a topic is rising or fading. A keyword with decent volume today but a steady five-year decline deserves less effort than a smaller one that is growing.
5. Score volume and difficulty in Semrush or Ahrefs
Run your shortlist through Semrush Keyword Overview or Ahrefs Keywords Explorer. Both report an estimated monthly search volume and a keyword difficulty (KD) score from 0 to 100, based largely on the backlinks of the pages already ranking. Treat both numbers as estimates and compare them within one tool rather than across tools.
A newer or smaller blog should favor keywords with lower difficulty and a clear, specific angle. A focused phrase with modest volume often brings more qualified readers than a broad head term you have no realistic chance of ranking for.
6. Check search intent against the live SERP
Search the keyword in a private browser window and study the first page. Are the results how-to guides, listicles, product pages, news stories, or definitions? Does Google show a featured snippet, a People Also Ask box, videos, or a local pack?
The format that ranks is the format Google believes satisfies the query. If every result is a step-by-step guide and you planned an opinion piece, change the angle or pick another keyword. This one check prevents more wasted posts than any metric in a tool.
7. Run a competitor gap analysis
Use the Semrush Keyword Gap tool or the Ahrefs Content Gap report to compare your domain with two or three competitors. The output lists keywords they rank for and you do not. Filter it to positions 1 to 20 for the competitors so you only see topics where they have real traction.
Do not copy their posts. Use the gap to find topics your readers care about that you have not covered, then write a better answer from your own expertise and data.
8. Group keywords into topic clusters
Sort the remaining keywords into clusters. Each cluster has one pillar page that covers the broad topic and several supporting posts that each answer one narrower question. Every supporting post links up to the pillar, and the pillar links down to each supporting post.
Clusters help search engines understand that your site covers a subject in depth. They also give editors a backlog that is already organized, so the next post is an obvious choice instead of a meeting.
9. Map one primary keyword to one post
Build a simple spreadsheet with one row per URL and one primary keyword per row. Before writing anything new, search the sheet. If an existing post already targets the keyword or a close variant, update that post instead of publishing a second one.
Two posts chasing the same query split clicks and links between them, a problem known as keyword cannibalization. You can spot it in Search Console when one query shows two or more of your URLs swapping positions over time. The fix is to merge the weaker post into the stronger one and add a 301 redirect.
Why long-tail keywords win for most blogs
Long-tail keywords are longer, more specific phrases such as "how to price a digital magazine subscription" instead of "magazine subscription." Each one usually has lower volume, but the reader's intent is clearer and the competition is lighter.
Long-tail phrases are also where most question-style queries live, and those are the queries that feed featured snippets and People Also Ask boxes. A practical test is to explain the post's angle in one sentence. If you cannot, the keyword is probably too vague to build a strong post around.
Worked example: keywords for a magazine's food section
The table below is an illustrative example of how a magazine could plan one section. The keywords are sample choices to show the method. No search volumes are listed, because real numbers vary by market and should come from your own tools.
| Cluster role | Example keyword | Likely intent (check the SERP) | Post format |
|---|---|---|---|
| Pillar | weeknight dinner ideas | Browse many options | Long roundup page |
| Supporting | 30 minute vegetarian dinners | Find quick recipes | Listicle with recipes |
| Supporting | how to meal prep for the week | Learn a process | Step-by-step guide |
| Supporting | sheet pan dinner recipes | Find recipes by method | Listicle |
| Supporting | what to cook with leftover rice | Solve a specific problem | Short how-to |
| Seasonal | thanksgiving side dishes make ahead | Plan for a date | Roundup, published early |
In this example, each supporting post links to the pillar and to one or two sibling posts. The seasonal post is checked in Google Trends first, so it goes live before interest starts to climb.
How publishers should plan keywords by section
Publishers have a natural advantage: their sections already behave like topic clusters. A magazine with Food, Travel, Personal Finance, and Home sections can treat each one as a separate keyword map with its own pillar pages and supporting posts.
Give each section editor ownership of their cluster sheet. That keeps the one-keyword-per-post rule enforceable, because the person commissioning a story can see what the section already ranks for. It also stops two desks from writing near-identical explainers that cannibalize each other.
Section-level clusters also make it easier to connect search traffic to revenue. When you know which section a reader arrived through, you can tailor the offer they see next, whether that is a newsletter signup or a subscription.

Frequently Asked Questions
How many keywords should a blog post target?
Most posts should have one primary keyword and a small set of closely related phrases. That keeps the article focused while still giving it enough depth to cover the topic naturally. If you find yourself targeting two distinct questions, they probably belong in two posts.
Are keywords for blog posts still important for SEO?
Yes. Keywords help search engines understand what a page is about and help writers match search intent. The key is to use them naturally in the title, headings, and body, and to build the article around the reader's actual question.
What free tools can I use to find keywords for blog posts?
Google Search Console shows the queries you already appear for, Google Keyword Planner gives volume ranges, and Google Trends shows seasonality and direction. Google's autocomplete and People Also Ask boxes are also free sources of real question wording.
What is a good keyword difficulty score for a new blog?
There is no universal cutoff, because Semrush and Ahrefs calculate difficulty differently. As a rule of thumb, a newer site should favor the lower end of each tool's scale and compare keywords within the same tool. Always confirm by checking whether the current top results are pages you could realistically outperform.
How do I avoid keyword cannibalization?
Keep a keyword map with one primary keyword per URL and check it before commissioning a new post. If Search Console shows two of your pages trading positions for the same query, merge the weaker page into the stronger one and add a 301 redirect.
Where can I find better blog subject ideas if I am stuck?
Start with customer questions, sales objections, support requests, and gaps in your competitors' coverage. Those sources usually produce stronger ideas for blogs than random brainstorming because they reflect real demand.
How do you end blog posts without sounding repetitive?
End by pointing to the reader's next step or a related resource in one or two lines. A clean ending feels intentional and closes the post with purpose, not filler.
