Keyword Density in 2026: Why There Is No Ideal Percentage

Keyword density is one of the oldest ideas in SEO, and one of the most persistent myths. Plenty of plugins and checklists still tell you to hit 1%, 2% or 3%, but Google has never published an ideal percentage and its own guidance points the other way. This guide sets out what Google actually says about keywords in 2026, why chasing a density figure wastes time, and what to focus on instead, with a quick way to spot over-optimised pages.

What is keyword density?

Keyword density is the number of times a word or phrase appears on a page, divided by the total number of words, shown as a percentage. A 1,000-word page that uses "boiler repair" 15 times has a density of 1.5% for that two-word phrase (or 3% if you count both words, depending on the tool).

The idea came from early search engines, which leaned heavily on term frequency. Repeat a word often enough and you looked relevant. That stopped working a long time ago, but the metric survived because it is easy to measure.

What Google actually says about keywords

Google has not been vague on this. Its official documentation makes four points that matter here.

1. Keywords still matter as a basic relevance signal. Google's "How Search Works" explains that "the most basic signal that information is relevant is when content contains the same keywords as your search query," and that keywords appearing "in the headings or body text of a webpage" can make it more relevant. So using the words people search for is not a myth. Measuring them to two decimal places is.

2. Repetition is not rewarded, and excessive repetition is spam. Google's spam policies define keyword stuffing as "filling a web page with keywords or numbers in an attempt to manipulate rankings," and give "repeating the same words or phrases so often that it sounds unnatural" as an example. The SEO Starter Guide adds that excessive repetition "is tiring for users."

3. Google understands variations. The Starter Guide says you don't need to anticipate every variation of a query, because Google's language matching can connect a page with queries that don't use its exact words. It also notes that writing naturally, rather than repetitively, gives you more chances to show up because you use more relevant terms.

4. There is no target word count, either. Google's helpful content guidance asks, as a warning sign: "Are you writing to a particular word count because you've heard or read that Google has a preferred word count? (No, we don't.)" The Starter Guide says "there's no magical word count target, minimum or maximum."

Put together: use your topic's words, use them naturally, and stop counting.

Why there is no ideal keyword density

Even if you wanted a magic number, it could not exist, for several reasons.

• Different queries need different language. A page about "commercial EPC certificates" will naturally repeat "EPC" far more than a page about "how to choose an accountant" repeats "accountant".
• Pages are not judged on one keyword. A good page ranks for hundreds of related queries. Optimising for one phrase's density ignores the rest.
• Google looks at meaning, not just matching strings. It can tell that "boiler service", "annual gas boiler check" and "boiler maintenance" are closely related.
• Competitor density is a red herring. Pages that rank well have something in common: they answer the query. Their density figures vary widely and are a side effect, not a cause. A proper analysis of competitors' SEO looks at topics, intent and links instead.
• Writing to a percentage makes copy worse. Forcing an exact phrase in "X times" produces clumsy sentences, which hurts the people you are trying to convert.

What to do instead of chasing keyword density

Match search intent first

Before writing, search your target query on Google, from the country you're targeting, and look at what ranks. Are the results guides, product pages, local listings, comparison tables or tools? If your page type does not match the intent, no amount of keyword tuning will fix it. A service page will struggle to rank for "how to bleed a radiator", and a blog post will struggle for "emergency plumber Leeds".

Cover the topic, not just the keyword

Think about the questions a customer would ask next. For a page about bathroom fitting in Birmingham, that might include price ranges, how long a refit takes, whether you handle plumbing and tiling, guarantees, and which areas you cover. Google's "People also ask" box and related searches are free sources of these questions. Topic coverage naturally brings in related terms and entities without you having to plan them.

Use entities and specifics

Entities are the things your topic involves: products, places, standards, organisations and people. A page about EV charger installation that mentions OZEV, 7kW and 22kW chargers, tethered vs untethered units, the DNO notification and your Gas Safe or NICEIC registration (where relevant) sends a far clearer signal than one that repeats "EV charger installation" 20 times.

Put the main phrase where it counts

Placement still beats repetition. Use your main topic, or a close variant, in:

1. The title tag, ideally near the start. Our guide to title tags and meta descriptions covers length and wording.
2. The H1, which should tell the reader what the page is about in plain words.
3. The opening paragraph, so readers and search engines see the topic straight away.
4. At least one subheading, where it fits naturally.
5. The meta description. It is not a ranking factor, but matching words are often bolded in results and it affects clicks.
6. Image alt text and the URL, where it genuinely describes the image or page.

Beyond that, write normally.

Avoid competing with yourself

If several pages on your site target the same phrase, they can split relevance and none ranks well. That is a bigger problem than density on any single page. See our guide to keyword cannibalisation for how to find and fix it.

How to spot keyword over-optimisation

Read the page aloud. If a sentence sounds like it was written for a robot, it probably was. Common signs:

• The exact same phrase appears in almost every paragraph, often in the same form.
• Sentences are bent out of shape to fit the keyword, such as "Our plumber Leeds services are the best plumber Leeds can offer."
• Footers or sidebars list dozens of towns or postcodes you "serve". Google's spam policies specifically mention "blocks of text that list cities and regions".
• Every image alt text, heading and link anchor uses the identical phrase.
• Hidden or tiny text, or text in the same colour as the background, contains keywords. This is a separate spam violation.
• The page has been "optimised" for a phrase that is grammatically awkward, such as "cheap SEO London UK".

Fixing an over-optimised page

1. Replace about half the exact-match repetitions with pronouns, synonyms or more specific terms.
2. Remove keyword lists in footers and sidebars. For local businesses, create genuine location pages only where you have something specific to say, or list service areas once in plain prose.
3. Rewrite headings so each one describes its section rather than repeating the keyword.
4. Add the depth that is missing: prices, steps, examples, FAQs and evidence of experience.
5. Request a recrawl of the page in Google Search Console once the changes are live.

Is a keyword density checker still useful?

Yes, but as a diagnostic rather than a target. A density checker shows what a page is actually about, as a machine reads it. If your top phrase is "cookie settings" or "free delivery" instead of the service you want to rank for, the page is sending the wrong signal.

Our free keyword density checker reads the main content of a page with the navigation, header and footer removed. It lists the most repeated single words and two- and three-word phrases with their share of the text, and shows whether each appears in the title, H1 and meta description. As a rule of thumb, it flags a single word making up more than about 4% of the text (with at least eight uses) as possible keyword stuffing. That is our heuristic for spotting repetitive copy, not a Google rule. It also warns when the main content is very short and when the top phrase is missing from the title, H1 and meta description. The tool needs a free account.

To check density alongside titles, headings, canonicals, schema and speed across your site, run a free website audit. Our SEO audit checklist covers the rest of on-page optimisation.

Frequently asked questions

Is keyword density a Google ranking factor?

Not in the sense of a target percentage. Google says keywords in headings and body text are a basic relevance signal, but it does not reward repetition, and excessive repetition breaks its keyword stuffing policy.

What is the ideal keyword density for SEO?

There isn't one. Google has never published a figure, and pages that rank well vary widely. Use your main phrase in the title, H1 and opening paragraph, then write naturally and cover the topic fully.

Can keyword stuffing get my site penalised?

Yes. Keyword stuffing is listed in Google's spam policies, and pages that violate them can rank lower or be removed from results, either by automated systems or through a manual action shown in Search Console.

How many times should I use a keyword in a blog post?

Enough that the topic is obvious, and no more. In practice that means the title, H1, introduction and a subheading or two, plus natural mentions and variations in the body.

Do meta keywords still matter?

No. Google's SEO Starter Guide states that Google Search doesn't use the keywords meta tag, so you can leave it out.
