Choosing the next blog topic gets easier when you separate three questions: are people searching for it, what do they need, and can your website provide a useful answer?
This guide shows how to use Google Keyword Planner for SEO research, then turn a keyword list into an article brief. The working example is a small agency planning content about WordPress, paid media and marketing software.
Quick answer: use Keyword Planner to explore demand, review the actual search results to understand the reader’s task, and choose one distinct problem your article can solve. A large search-volume number is a starting point, not a traffic forecast.
The search demand behind this topic
Before preparing this guide, we checked Semrush’s public Keyword Search Volume Checker. Its United States database showed these estimates on 8 October 2026:
| Keyword | Monthly US searches | Semrush difficulty | Editorial decision |
|---|---|---|---|
| google keyword planner for seo | 1,300 | 97/100 | Relevant broader topic; highly competitive. |
| using google keyword planner for seo | 320 | 48/100 | More specific target for this practical guide. |
| how to use google keyword planner for seo | 90 | 79/100 | Answer within the same guide rather than create a second overlapping post. |
Source: Semrush’s keyword report. The related phrases appeared in its suggestions. These are third-party estimates of Google search demand, not a live export from Seolign’s Google Ads account. The tool did not display a dataset month. They describe the US market, not UAE or Pakistan demand.
The narrower phrase makes sense for an instructional article. Its difficulty score is lower, but 48/100 still does not make ranking easy for a new website. This is a choice based on relevance and relative opportunity, not a promise of first-page visibility.
If your business serves Dubai, repeat the research for the UAE before planning local content. A US figure cannot tell you how many potential customers are searching in Dubai.
Open Google Keyword Planner
Google Keyword Planner sits inside Google Ads. Google’s current help page says account setup, including billing information, must be completed to access basic keyword-idea features. Follow the requirements shown in your account and review any campaign settings before activating advertising.
Open Tools → Planning → Keyword Planner. Use Discover new keywords to explore ideas, or Get search volume and forecasts to check an existing list. You can begin discovery with phrases or a website address.
Google’s Keyword Planner instructions explain the available research paths. This article is a documentation-based workflow; it does not claim that we tested your private Ads account.
Build a useful keyword shortlist
1. Begin with a reader’s problem
“Marketing” is too broad for an initial article brief. “How do I choose a blog topic for my agency?” gives you a reader, a task and a useful outcome.
Write five seed ideas in ordinary language. For an agency website, a starting set might be keyword research, WordPress SEO, Google Ads planning, email welcome sequences and Shopify product pages. These are brainstorming inputs; their search demand still needs checking.
Include phrases your customers actually use in enquiries. Someone asking why their website gets no visitors has a different problem from someone choosing between two email platforms. The eventual articles should reflect that difference.
2. Keep the research settings consistent
Choose the intended market, an appropriate language setting, the search network and a meaningful date range. For a basic comparison, use the same settings across every candidate. Keep separate lists when evaluating different countries.
Record the research date beside your notes. A number without its location and period is difficult to interpret later. Comparing one keyword’s US data with another keyword’s worldwide figure can lead you to choose the wrong topic.
3. Remove ideas you cannot serve well
A keyword can show demand and still be a poor fit. If your agency writes about website performance, a query about a video game’s frame rate probably belongs outside your content plan, even if “performance” connects the two.
For each candidate, ask: who would read this, what would they do after reading it, and what specific help can we provide? Keep the ideas with clear answers. Place the rest in a research backlog rather than forcing them into tomorrow’s publishing slot.
4. Inspect the results before choosing an angle
Look at the leading search results for the candidate phrase. Are they tutorials, product pages, reviews, videos or troubleshooting discussions? Then inspect a few pages closely enough to see what they actually explain.
A software login query usually calls for the official login page. Writing a long article around that query may attract the wrong audience. A query about choosing settings is more suitable for a step-by-step guide.
Search results also help you spot a useful gap. Perhaps existing guides explain a menu but never show how to make a decision. Your article can contribute an original decision table, worked example or reusable checklist.
Read the numbers correctly
Google describes average monthly searches as a rounded average for a keyword and its close variants under the selected settings. The default period is 12 months. Its competition column describes advertisers; it does not measure the difficulty of ranking an article organically.
Paid forecasts answer a different question: how ads might perform under assumptions such as bids and budget. Do not treat projected ad clicks as predicted blog visitors. See Google’s explanation of historical metrics and forecasts.
| Signal | Useful question | Wrong conclusion to avoid |
|---|---|---|
| Search volume | Is there enough relevant demand to investigate? | My article will receive this many visits. |
| Advertiser competition | Are advertisers competing for this query? | Low competition means easy organic rankings. |
| Bid estimates | Does the query have potential advertising value? | This is what my blog will earn per click. |
| SEO difficulty estimate | How challenging does this provider consider the results? | The score guarantees a ranking outcome. |
| Search-result format | What answer do readers appear to expect? | Every query needs a long written guide. |
When related phrases have similar meaning, do not automatically add their volumes together. You may be counting overlapping demand. Plan one useful page around the shared task, then cover the natural wording variations within it.
Turn research into an article brief
Imagine a small agency choosing between “SEO tools,” “using Google Keyword Planner for SEO” and “WordPress sitemap troubleshooting.” The first is broad. The second has measured demand in our public-tool check. The third is a separate problem that needs its own research.
For this article, the brief looks like this:
- Reader: a small-business owner or marketer planning useful website content.
- Main task: choose a blog topic using search demand and reader intent.
- Primary phrase: using Google Keyword Planner for SEO.
- Original contribution: a dated keyword comparison, a decision worksheet and an article-planning example.
- Boundaries: no invented Google Ads export, no promise of visits, and no claim that low advertiser competition means easy SEO.
This creates a stronger starting point than “write 2,000 words about keywords.” It also gives an editor clear questions to check before approving publication.
A decision worksheet you can reuse
Copy these five fields into your planning notes for each candidate:
- Reader and task: describe both in one sentence.
- Demand evidence: record the source, market, date, volume and any limitations.
- Expected page format: explain why a tutorial, comparison or other format fits.
- Your contribution: list the example, evidence or tool the article will add.
- Existing-page overlap: identify any article you should improve instead of duplicating.
Reject a candidate if the reader is unclear or you cannot add useful substance. Among the remaining candidates, compare demand and the strength of the competing pages. This avoids allowing one impressive number to make the whole decision.
For example, two phrases that both ask how to use Keyword Planner for SEO belong in one guide unless research reveals a different task. A separate article about Keyword Planner access problems could be justified if it provides a distinct troubleshooting workflow.
Your pre-publication checklist
Before publishing, confirm that the opening answers the central question and every section helps the reader complete the task. Give tables descriptive headings, explain examples, and label illustrative material clearly.
- Use a descriptive title and a concise meta description that match the article.
- Check changing software details against official sources.
- Add relevant internal links where the next guide helps the reader.
- Credit third-party images; do not present stock photos as testing evidence.
- Identify the publisher and describe AI assistance or research limitations honestly.
Google’s people-first content guidance emphasises useful, original work. A publishing quota should leave enough time for that work.
After publication, use Google Search Console to observe actual search performance. If impressions appear but readers seldom click, review whether the title accurately describes the answer. If visitors arrive but do not finish their task, improve the article’s explanation and examples before adding more keywords.
Once your topic is chosen, our Rank Math setup guide explains the WordPress SEO basics. Our internal-linking workflow helps connect the new article to related pages. If you are using research for paid campaigns, continue with the Google Ads search-terms review.
Common questions
Can I use Google Keyword Planner for SEO?
Yes. Its demand estimates can inform topic research. Combine them with search-result review and a clear reader task, because the tool is designed primarily for advertising planning.
How much search volume should a blog keyword have?
There is no universal target. Compare the likely audience, the effort required to answer well and your ability to compete. A specific useful topic can be worth covering even when its demand is lower than a broad phrase.
Does low competition mean my article will rank easily?
No. Keyword Planner’s competition describes advertisers. Assess organic results separately, and treat third-party SEO difficulty scores as estimates.
Why do different tools report different volumes?
Check the market, research period and each provider’s methodology. Keep one consistent source for comparisons, note limitations, and use your own search-performance data to assess the article after publication.
Should I publish a separate post for every keyword variation?
Only when the reader’s task differs enough to warrant a separate answer. Similar wording often belongs on one well-developed page.
