You know that feeling when your homepage sits quietly on page two, like a shopfront on a foggy back street? You’ve poured hours into a primary keyword, yet the traffic trickles in, thin as drizzle. Secondary keywords flip that story. They widen the path, pulling in real queries people actually type, and signal to search engines that your page truly covers the topic. Here’s the counterintuitive bit: you don’t need more pages , you need richer relevance on the pages you already have. After helping SMEs and small agencies turn limp blogs into lead magnets, I’ve seen secondary keywords lift click through rates and grow impressions without bloating the site. Read on and you’ll learn the practical workflow I use daily, plus how MyMarketr’s live Top Keywords table and guided ideation make this almost unfair in your favour.
Key Takeaways
- Secondary keywords expand semantic coverage around your primary term, increasing relevance and capturing more real-world queries without adding extra pages.
- They deliver wider visibility, higher CTR, smoother copy (less stuffing), stronger topical authority, and help prevent keyword cannibalisation.
- Find them by mapping searcher intent, translating customer language into search phrases, and validating via Autocomplete, People Also Ask, Search Console, competitor pages, and MyMarketr’s research tools.
- Cluster by intent (informational, transactional, navigational), assign one primary per core page, and use tightly related secondary keywords in sections, FAQs, and interlinked support content.
- Optimise placement by weaving variants into H2/H3s, the first 150 words, conclusions, concise FAQs, and relevant image alt text, while refining meta titles, descriptions, headings, and internal links with MyMarketr’s My Pages insights.
- Measure impact with before–after windows tracking impressions, clicks, CTR, and positions; promote rising terms into subheadings or new pages and iterate using MyMarketr’s Top Keywords and Activity Feed.
What Are Secondary Keywords?
Secondary keywords are the closely related terms that support your primary keyword. Think of synonyms, variations, long tail phrases, and subtopics that expand the context of a page. If your primary keyword is “SEO Swindon”, then terms like “local SEO services”, “SEO consultants in Swindon”, and “how to rank a Swindon business” are natural secondary candidates. They don’t replace the main topic. They enrich it, so your content answers more of the queries a real person might ask when they arrive.
In practice, secondary keywords help you build semantic coverage. Search engines see the breadth and depth, and users feel understood because you’re addressing their follow up questions without them needing another tab.
Why Secondary Keywords Matter For SEO
Secondary keywords matter because they boost relevance and reach. You’re no longer betting the farm on one exact phrase. Instead, you’re matching a cluster of intents that often sit around the main query.
Benefits you’ll notice:
- Wider visibility for related searches, not just the head term.
- Fewer temptations to stuff the primary keyword. Your copy reads better and ranks better.
- More topical depth, which supports authority signals and keeps people on the page longer.
- Protection against cannibalisation by clearly defining what this page owns within a theme.
On a practical level, when your page ranks for ten related phrases instead of two, CTR improves, long tail traffic rises, and you move up the results for your primary target because the page is clearly useful.
Finding Secondary Keywords
Expand From Core Topics And Intent
Start with the core. Write your primary keyword at the top of a blank doc. Then list the real jobs to be done for that searcher. What are they trying to accomplish? Buying, comparing, learning, fixing. For each intent, note questions you’d ask if you were them. That’s your first pool of secondary ideas.
Then, translate everyday questions into search language. If a potential client says, “We tried Google Ads and it ate our budget”, the search pattern might be “how to reduce Google Ads spend” or “improve Google Ads CTR”. This habit turns customer language into search phrases you can actually rank for.
Research Methods And Tools
Now validate the ideas. Use tools to see volumes, variations, and difficulty. Autocomplete results, People also ask, and related searches reveal how users explore the topic. Competitor pages show what’s already winning.
Practical toolkit:
- Google Search Console to discover queries you already impression for and low hanging long tail opportunities. See official help on reporting to guide what to check next: https://support.google.com/webmasters/answer/9128668?hl=en
- A competitive research suite to review overlaps and gaps. MyMarketr’s Competitor Analysis highlights keyword gaps you can own faster than head terms.
- MyMarketr’s New Content Ideas module to generate theme aligned suggestions you can save to My Content Ideas for later.
You can also scan the live Top Keywords table inside your Project to spot terms with impressions but weak CTR. Those are prime candidates for secondary inclusion in headings, FAQs, or meta descriptions.
Mapping Secondary Keywords To Your Site
Cluster By Intent And Topic Depth
Group your keywords into a theme. Within that set, assign one primary keyword to the core page and reserve secondary keywords that are tightly related. Keep broader or tangential secondary terms for support sections, FAQs, or future articles that interlink.
I use three quick buckets:
- Informational: how to, what is, guides, comparisons.
- Transactional: pricing, services near me, quotes, demos.
- Navigational or brand: your brand vs competitor, login, features.
Within each page, map subheadings to each bucket’s questions. Your page becomes a clear outline of intents, which improves scannability and semantic coverage.
Prioritise By Opportunity And Difficulty
Not all secondary keywords are equal. Prioritise those with a healthy blend of relevance, attainable difficulty, and decent volume. A simple grid works: High relevance plus low to medium difficulty gets a green light. High difficulty but strategic value stays on a watchlist.
Inside MyMarketr, review:
- Average position and impressions in the Top Keywords table for quick wins.
- Competitor ranking strengths to decide when to punch up or angle for long tail variants.
- The Activity Feed to track what you changed and when, so you can attribute gains correctly.
Using Secondary Keywords In Content
Placement Best Practices
Place secondary keywords where they feel native.
- Introduce one or two in H2 or H3 subheadings that answer specific questions.
- Add a compact FAQ that mirrors People also ask language.
- Use natural phrasing in the first 150 words and near conclusions, but stay readable.
- Slip variants into image alt text when the image genuinely depicts that angle.
Read your draft out loud. If a phrase sounds robotic, bin it. If it flows, keep it. Better to rank for slightly fewer phrases with high engagement than chase everything with awkward wording.
On-Page Elements To Optimise
- Meta title: weave a primary and a single secondary where it fits.
- Meta description: target curiosity and clarity. Include one secondary variant.
- Headings: distribute intent led phrases through H2s and H3s.
- Body copy: cluster ideas into short, useful sections.
- Internal linking: connect to deeper resources and service pages that extend the journey. For example, link to your benchmarking guide when discussing competitor performance: https://mymarketr.io/blog/digital-marketing-benchmarking-guide/
Use MyMarketr’s My Pages to associate each page with its core and secondary targets, then review optimisation insights before you publish.
Measuring Impact And Iterating
Track Rankings, CTR, And Engagement
If you don’t measure, you guess. Track impressions, clicks, CTR, and average position for both the primary and secondary keywords. Watch how many distinct queries a page earns impressions for after your update.
Use a simple before and after window. Note the publish date in your Activity Feed, then check:
- Queries gained per page.
- CTR changes on phrases boosted in headings and FAQs.
- Time on page and bounce, which reflect whether the expanded coverage actually helped a reader.
The Top Keywords table in your Project acts like a daily pulse check. You will see which secondary phrases begin to surface and which deserve a stronger placement next iteration.
Refine Clusters And Content Over Time
Iterate monthly. Retire weak variants, elevate promising ones into subheadings, and spin out a new article when a secondary term starts earning enough impressions to justify its own page. That’s how you scale a topic without making a content maze.
Two quick moves that pay off:
- Map rising secondary terms to relevant internal pages to distribute authority.
- Use Quick Create inside MyMarketr to generate an outline for a new post that targets the growing variant, then review the draft under My Created Content before publishing.
When you need deeper competitive context, the Competitor Dashboard shows domain level benchmarking and keyword overlap, so you can steer your cluster away from crowded angles and towards gaps you can win.

Frequently Asked Questions
What are secondary keywords in SEO and how do they work?
Secondary keywords are closely related terms—synonyms, variations, long‑tail phrases, and subtopics—that support your primary keyword. They expand a page’s semantic coverage, help you match multiple intents, and boost relevance. That breadth improves impressions, click‑through rates, and rankings for the main term because your content answers more real queries.
How do I find secondary keywords that increase CTR?
Start from searcher intent: list jobs to be done (learn, compare, buy, fix) and turn customer language into search phrases. Validate with autocomplete, People also ask, related searches, competitor pages, and Google Search Console. Tools like MyMarketr’s Top Keywords and Competitor Analysis highlight gaps and low‑hanging long‑tail opportunities.
Where should I use secondary keywords on a page?
Place secondary keywords naturally: in H2/H3s that answer specific questions, a compact FAQ, the first 150 words, and near the conclusion. Optimise meta title and description with a single relevant variant, use genuine alt text where appropriate, and add internal links to deeper resources to strengthen topical coverage and journeys.
How many secondary keywords should I target per page?
Aim for a focused cluster rather than a list—often 5–15 closely related secondary keywords per page, depending on content depth. Map them to subheadings and FAQs, prioritising relevance and attainable difficulty. Avoid stuffing; write naturally, then monitor impressions, CTR, and average position to refine the set over time.
Are secondary keywords the same as LSI or semantic keywords?
Not exactly. “LSI keywords” is an outdated term; search engines use modern semantic understanding, not classic LSI. Secondary keywords are a practical set of semantically related phrases you intentionally target to broaden relevance. Think entities, variations, and user intents—used naturally to improve coverage, not forced repetitions.
