How to Use Semrush’s Keyword Magic Tool to Build a Content Plan

Finding topics is easy. Finding the right topics, in the right order, is what separates a random blog from a plan that grows traffic. Semrush’s Keyword Magic Tool starts with one idea and expands it into thousands of related searches, each with data to help you decide what to write first.

This guide walks through the full process: seed keyword, filters, clusters, export, and a simple content calendar.

Quick Answer

To build a content plan with Semrush’s Keyword Magic Tool, enter a broad seed keyword, filter the results by keyword difficulty, search volume, and intent, and then group related terms into topic clusters. Export your chosen keywords, assign one primary keyword to each article, and schedule those articles on a calendar based on difficulty and business value. Easier, high-intent keywords should usually come first.

What the Keyword Magic Tool Actually Does

The Keyword Magic Tool is a keyword research database inside Semrush. You type in a starting word or phrase, and it returns a long list of related searches that real people type into Google.

For each keyword, you can see useful information such as:

• How many people search for it each month
• How hard it is likely to be to rank for it
• Whether the searcher wants information, a product, or a specific website
• Related questions people ask around the same topic

Your job is not to use every keyword it shows you. It is to use the data to make smart, ordered choices.

Before you start, it helps to read a wider comparison of the major platforms. Our guide covering the Ahrefs vs Semrush comparison for small businesses explains where Semrush is strongest, which is useful context before you build a whole plan inside one tool.

Step 1: Start With a Good Seed Keyword

A seed keyword is a short, broad term that describes your topic area. It is not the exact title of an article. It is the starting point the tool expands.

How to choose a seed keyword

1. Think about one core service, product, or topic your site covers.
2. Keep it short, usually one to three words, such as “email marketing”, “home workouts”, or “invoice software”.
3. Avoid brand names at this stage, unless you only want ideas around that brand.
4. Run separate searches for each main topic area instead of mixing everything into one list.

You can explore the tool and other Semrush features through the Semrush official website, where you can also check what your current plan includes.

Step 2: Filter the List Down to Realistic Targets

A single seed keyword can return tens of thousands of results. Most of them will be wrong for you. Filters are how you cut that noise down to a working list.

Filter by keyword difficulty

Keyword Difficulty, often shortened to KD, is an estimate of how hard it will be to reach the first page of Google for that term. If your site is new or small, start with lower difficulty scores and work up over time.

A practical approach looks like this:

• New sites: focus mainly on very easy and easy keywords.
• Growing sites: mix easy keywords with a few medium ones.
• Established sites: add harder terms where you already have topical strength.

Filter by search volume

Volume tells you roughly how many searches a keyword gets each month. Higher is not always better: a keyword with 200 searches and strong buying intent can beat a vague term with 5,000.

Set a minimum volume that makes sense for your market. For a local or niche business, even 50 to 100 searches a month can be valuable. For a national blog, you might set the floor higher. Just do not delete every low-volume term, because long-tail keywords are often the easiest wins you will find.

Filter by search intent

Intent describes what the searcher wants. Semrush labels keywords by intent types such as informational, navigational, commercial, and transactional.

• Informational: the person wants to learn. Best for guides, tutorials, and blog posts.
• Commercial: the person is comparing options before buying. Best for comparison and review content.
• Transactional: the person is ready to act or buy. Best for service and product pages.
• Navigational: the person is looking for one specific site. Usually not worth targeting unless it is your own brand.

For a blog content plan, you will mostly choose informational keywords, with some commercial ones mixed in. Matching intent to content type matters, because Google rarely ranks a sales page for a “how to” question, and rarely ranks a long guide for a “buy now” search.

Use the questions filter

One of the most useful views in the tool shows keywords phrased as questions. These are gold for content planning. Each question can become a section heading, a short standalone article, or an FAQ entry.

Step 3: Group Keywords Into Topic Clusters

Writing one article per keyword is an old and wasteful method. Modern content planning works in clusters. A cluster is a group of closely related keywords that one strong article, or one small set of linked articles, can cover properly.

How clustering works in practice

1. Sort your filtered list and look for keywords that share the same core meaning.
2. Put one main keyword at the top as the primary target for the page.
3. Add five to fifteen supporting keywords underneath it. These become subheadings, examples, and FAQ questions inside the same article.
4. Use the tool’s grouping feature to sort terms by shared words, then review each group by hand before trusting it.

For example, “best invoice software for freelancers” and “how to invoice as a freelancer” are related but not identical: one suits a comparison article, the other a how-to guide. Automatic grouping gives a starting point; your judgment makes the final call.

Build pillar pages and supporting articles

Once you have clusters, arrange them into a simple structure. A broad pillar page covers the main topic in depth. Smaller supporting articles cover one subtopic each and link back to the pillar.

This structure helps readers and search engines understand which page is your main authority on the topic, and stops your own articles competing for the same keyword.

Step 4: Export a Clean Keyword List

After filtering and grouping, select only the keywords you genuinely plan to use. Add them to a keyword list inside Semrush, or export them into a spreadsheet.

Your exported list should include, for every keyword:

• The keyword itself
• Monthly search volume
• Keyword difficulty
• Search intent
• The cluster or article it belongs to

Keep the export clean: delete duplicates, remove terms for services you do not offer, and drop anything that does not match your audience’s country or language. A short, honest list beats a giant list nobody opens again.

Step 5: Turn the List Into a Content Calendar

Now convert each cluster into a scheduled piece of content.

How to prioritise what to write first

1. Start with easy wins: low difficulty, clear intent, and a close link to what you sell or offer.
2. Add one pillar page early: it takes longer to write, but every supporting article you publish afterwards strengthens it.
3. Mix formats: alternate guides, comparisons, checklists, and question-based articles so your blog does not feel repetitive.
4. Be realistic about pace: one strong article per week, published consistently, beats five rushed articles followed by two months of silence.

What each calendar entry should include

• Working article title
• Primary keyword and its supporting keywords
• Content type, such as guide, comparison, or tutorial
• Target reader and search intent
• Planned publish date and writer
• Internal links to add once the article is live

Review the calendar monthly. If an article performs well, expand its cluster. A content plan is a living document, not a contract.

Common Mistakes to Avoid

• Chasing volume only: high-volume keywords are usually the hardest and the vaguest. Balance volume with difficulty and intent.
• Ignoring intent: a beautifully written article in the wrong format will not rank, no matter how good the writing is.
• One keyword, one article: this creates thin, overlapping pages that compete with each other. Cluster instead.
• Never updating the plan: search demand changes. Re-run your seed keywords every few months and refresh old articles.
• Forgetting internal links: a new article with no links to or from related pages is much harder for readers and search engines to find.

Conclusion

The tool turns one rough idea into thousands of measured options. The real skill is filtering that list honestly, grouping it sensibly, and scheduling it at a pace you can maintain.

Start with a clear seed keyword, cut the results down by difficulty, volume, and intent, build clusters around one primary keyword each, and put those clusters on a calendar. Follow that order and you will have a content plan that is realistic, focused, and built to grow over time rather than a spreadsheet you abandon after week two.

Frequently Asked Questions

How many keywords should one article target?

Give each article one primary keyword and a small group of closely related supporting keywords. The supporting terms should appear naturally as subheadings, examples, and questions, not as a list you force into the text.

What keyword difficulty should a new website aim for?

A new site should mostly target the lowest difficulty keywords it can find in its niche, then move to medium difficulty as it gains content, links, and topical authority in one area.

How often should I rebuild my content plan?

Review it every month and do a fuller refresh every three to six months. Search trends, your product range, and your site’s authority all change, so your plan should change with them.

Can I build a content plan with the free version of Semrush?

You can do basic research with a free account, but the number of results and reports is limited. It is enough to test the workflow and build a small starter plan before deciding whether a paid plan is worth it.

What is the difference between a keyword list and a content calendar?

A keyword list is raw research: terms and data. A content calendar turns that research into decisions, with titles, formats, owners, and publish dates, so the work actually gets written and released on schedule.
