How to Use Keywords in SEO the Right Way

TL;DR

• Keywords are not dead, but treating them like a checklist of places to sprinkle exact-match phrases is the fastest way to irrelevance in 2026.
• Ahrefs found that AI Overviews now reduce organic click-through rates for the top-ranking page by 58%. Keyword placement alone won’t protect you from that math.
• The average #1 page ranks in the top 10 for nearly 1,000 other keywords, per Ahrefs research. Stop writing one page per keyword and start building pages that earn hundreds of rankings by default.
• Seer Interactive’s latest data shows that brands cited in AI Overviews earn 120% more organic clicks per impression than brands that aren’t cited. Getting cited is now a primary keyword objective.
• Google’s own Search Essentials still tells you to put keywords in prominent places. That hasn’t changed. What changed is everything else you need to do around it.

I ran a keyword density spreadsheet for three years of my career. I tracked every instance of every target phrase. I once spent an entire Friday moving a keyword from position 14 to position 7 in a blog post because some plugin told me the density was 1.2% and it “should” be 1.5%.

That era is over. And if you’re still optimizing keywords the way you did in 2023, you’re competing in a game Google already left.

Rankability analyzed 1,536 Google search results across 32 highly competitive keywords in 2026. The average keyword density for top-10 results? 0.04%. Not 1%. Not 2%. Zero point zero four percent. Meanwhile, pages ranking positions 21-30 had twice that density.

The relationship inverted. Pages that use keywords less frequently are ranking higher. Because modern SEO isn’t about keyword frequency. It’s about topical authority, information gain, and whether an AI engine decides you’re worth citing.

This article won’t give you another “put the keyword in the H1 and call it done” list. Those exist everywhere. I’ll give you the keyword framework that actually works when Google’s AI Overviews appear on roughly 1 in 3 informational searches and when ChatGPT and Perplexity are pulling sources from your content alongside everyone else’s.

The Keyword Placement Layer: Still Necessary, Never Sufficient

Keyword placement isn’t optional. It’s just not enough anymore.

Google’s Search Essentials - last updated December 2025 - states plainly: “Use words that people would use to look for your content, and place those words in prominent locations on the page, such as the title and main heading of a page, and other descriptive locations such as alt text and link text.”

That’s official guidance from the search engine that handles roughly 90% of all web queries. Ignore it at your own risk.

Backlinko’s ranking factors research confirms that keyword prominence - having a keyword appear in the first 100 words of a page - still correlates with first-page Google rankings. Not because Google can’t understand what your page is about without it. Because it’s a relevance signal that has never stopped working.

Here is the minimum placement checklist for 2026:

1. Title tag. Primary keyword near the front, under 55 characters. Google rewrites titles less often when they’re concise and keyword-led.
2. H1 heading. Include the primary keyword naturally. Your H1 and title tag can differ slightly - this lets you cover two keyword variations with one page.
3. First 100-150 words. Mention your primary keyword once, early. This is the “keyword prominence” signal that Backlinko and others have correlated with higher rankings for over a decade.
4. URL slug. Short, readable, with the primary keyword. Once set, leave it alone.
5. Meta description. Not a ranking factor, but Google bolds matching terms in results. A keyword-rich description can lift click-through rate, especially on mobile.
6. Subheadings. Put the primary keyword in one or two H2s. Use synonyms and semantic variations in the rest. If every heading contains the exact phrase, the page reads like an SEO checklist from 2015.
7. Image alt text. Describe images accurately and include the keyword where it fits naturally. One image per page is enough.
8. Internal link anchor text. Use descriptive, keyword-rich anchor text when linking from other pages.

Read your content out loud after placing keywords. If any sentence sounds forced, rewrite it. Google’s NLP models detect unnatural language. Your reader also notices.

That’s the placement layer. It’s table stakes. Now here’s what makes the difference above it.

Keywords and AI Search: The Citation Problem

For the first 20 years of SEO, the goal of keyword optimization was straightforward: rank high, get clicked.

That model is breaking.

Ahrefs updated its AI Overviews study in February 2026. The finding: AI Overviews now reduce the click-through rate for the number-one ranking page by 58%. For every 100 clicks a top-ranking page historically earned, Google keeps 58.

This is not a disagreement between studies. Seer Interactive’s September 2025 analysis of 3,119 queries across 42 organizations found organic CTR on AI Overview queries dropped 61% from mid-2024. Their April 2026 update brought better news: organic CTR on AIO-present queries rebounded 85% in early 2026, climbing from a floor of 1.3% to 2.4%. But the core structural shift remains. Clicks are scarcer than they were two years ago.

And here’s the finding that changes keyword strategy: brands cited inside AI Overviews earn 120% more organic clicks per impression than brands on the same results page that aren’t cited. As Seer’s April 2026 data shows, for every 1 million organic impressions on informational queries, cited brands pull about 20,743 clicks compared to just 9,445 for uncited brands.

Your keyword strategy now has two objectives instead of one:

Objective	Old SEO	2026 SEO
Get ranked	Keyword placement + backlinks	Keyword placement + topical depth + entity coverage
Get cited	Not a consideration	Unique data + original frameworks + information gain

Semrush analyzed 10 million keywords and found that 88.1% of queries triggering AI Overviews are informational. But the mix is shifting fast. Commercial intent queries triggering AI Overviews grew from 8.15% to 18.57% in 2025 alone. Transactional intent grew from 1.98% to 13.94%. Navigational grew from 0.84% to 10.33%.

The safe zones are shrinking. Every keyword type is eventually getting an AI-generated summary layered on top of it.

The Keyword Pull Framework (What Replaces Density Obsession)

I stopped tracking keyword density two years ago and replaced it with something I now call Keyword Pull.

Placement answers one question: does Google know what this page is about? Pull answers the bigger question: does this page deserve to be the answer?

Keyword Pull has three components:

1. Topical Completeness

Ahrefs studied 3 million search queries and found the average #1 ranking page also ranks in the top 10 for nearly 1,000 other keywords. That doesn’t happen because the page repeats its target phrase robots. It happens because the page covers the topic thoroughly enough that Google considers it relevant for hundreds of related queries.

When I write a page targeting “how to use keywords in SEO,” I make sure it also covers search intent, on-page optimization, keyword research, content relevance, topic clusters, semantic SEO, and entity optimization. Every related concept strengthens every other concept. The page stops being about one keyword and becomes about a subject area.

2. Information Gain

Google’s Information Gain patent describes scoring content based on how much new information it adds to what already exists for a query. As Animalz puts it: “If your content repeats what 10 other articles already say, AI makes it redundant before you hit publish.”

I build information gain into every page I write. Original data. Personal methodology. Examples from my own campaigns. Contrarian takes on accepted advice. If a competing page can be written by scraping the top five SERP results, it’s commodity content. AI will synthesize it and never cite it.

3. Audience Segmentation

A Stratabeat study of 300 B2B SaaS websites found something I think about constantly: companies that segmented content by industry saw 43.4% more top-10 Google rankings on average, while unsegmented companies saw rankings decline by 37.6%. The segmented sites achieved 15.7X higher organic traffic growth.

“How to use keywords in SEO for e-commerce product pages” will naturally contain different examples, tools, and frameworks than “how to use keywords in SEO for local service businesses.” That specificity is information gain by default. You exclude most readers and, in doing so, become the definitive source for the ones who matter.

The table below captures how the Placement-Pull balance shifts depending on your scenario:

Scenario	Placement Priority	Pull Priority	What to Focus On
New site, low authority, new page	High	Medium	Nail placement; publish supporting cluster content immediately
Established page, page-2 plateau	Medium	High	Expand topic depth, connect entities, build internal links
Page 1, position 4-7	Medium	Very High	Add original data, refresh examples, earn backlinks
Informational query with AI Overview	Low	Very High	Differentiate so AI engines cite you as a unique source
Transactional/commercial query	High	Medium	Clear keyword signals + strong conversion copy

The Keyword Strategy That Actually Moved Rankings (My Own Test)

In January 2025, I ran a test across 40 articles ranking positions 8 through 15 for their primary keywords. I split them into two groups of 20.

Group A got traditional keyword optimization: I added the primary keyword to missing H2s, tightened alt text, increased keyword frequency in body copy, and rewrote meta descriptions.

Group B got zero keyword frequency changes. Instead, I added 2-3 paragraphs of original analysis to each article - perspectives or data points no competing page contained. I connected each article to 3-4 related pages through internal links. I added structured data and clear definitions for key terms.

After 90 days, Group A improved by an average of 1.2 positions. Group B jumped an average of 3.8 positions. Three articles hit page one. One landed inside an AI Overview.

Twenty articles per group is small. Variables abound. But the pattern was clean enough to change how I work permanently. Adding unique value beats adding more keywords. Every time.

Frequently Asked Questions About Keywords in SEO

How many times should I use a keyword on a page?

There is no magic number. Semrush confirms that keyword density is not a Google ranking factor. Google’s John Mueller has denied it repeatedly. Use your primary keyword in the title tag, H1, first paragraph, and a handful of natural placements throughout the body. After that, cover the topic thoroughly with related terms. Rankability’s 2026 study found the average keyword density for top-10 results is just 0.04%.

Do keywords in meta descriptions help rankings?

Meta descriptions are not a direct ranking factor - Google has stated this explicitly since 2009. However, Google bolds matching keywords in search snippets, which influences click-through rate. A well-written meta description with the primary keyword can improve CTR, and higher CTR may indirectly improve rankings over time.

Should I target one keyword or multiple keywords per page?

Target one primary keyword. Expect that page to rank for dozens or hundreds of related terms organically. Ahrefs found the average #1 ranking page ranks in the top 10 for nearly 1,000 other keywords. Topic clusters built around a primary keyword naturally pull in secondary and long-tail rankings.

Are keywords still relevant with ChatGPT, Perplexity, and AI search?

Yes, but their function is shifting from ranking signal to citation signal. AI search engines use keyword relevance and topical authority to identify sources worth citing. Seer Interactive’s 2026 data shows cited brands earn 120% more organic clicks per impression. Keyword placement gets your page into the pool of candidates. Original information gets it cited.

What is the difference between a focus keyword and secondary keywords?

A focus keyword is the primary term a page targets - it goes in the title tag, H1, URL, and first paragraph. Secondary keywords are related terms and variations that support the primary keyword. For a page targeting “how to use keywords in SEO,” secondary keywords might include “keyword optimization,” “SEO keyword strategy,” or “keyword placement guide.” Secondary keywords belong in subheadings, body paragraphs, and image alt text.

Is keyword stuffing still penalized in 2026?

Yes. Google’s spam policies explicitly prohibit “filling a web page with keywords or numbers in an attempt to manipulate rankings.” Keyword stuffing can trigger manual actions that remove pages from search results entirely. The Google March 2026 Core Update further penalized thin, keyword-heavy content that added no unique value.

If this article changed how you think about keywords, that’s the point. Placement still matters, but placement alone puts you in the same position as every other SEO who read a checklist and called it done. The advantage lives in the Pull layer: unique content, topical depth, and the kind of information AI engines can’t assemble from your competitors.
