Wondering where to add keywords for SEO? Here is the direct answer: there are nine places on a page where your keyword genuinely matters, and one famous place that does nothing at all. Getting your target keyword into the right spots, naturally and without stuffing, helps search engines understand your page. Below: whether keywords still matter, how to pick them, the nine placements with right and wrong examples, the dead meta keywords tag, the character limits that turn out not to exist, and the mistakes that undo the rest.
Do keywords still help SEO?
Yes, keywords still help SEO, but not the way they did years ago. The honest modern answer is that SEO is now about topics and search intent, not keyword density. You no longer win by repeating a phrase many times; in fact, that hurts.
Instead, you use your keyword to signal what the page is about and to match the language people search with, then cover the topic thoroughly and answer the intent behind the search. Think of keywords as guides that tell search engines and readers your page is relevant, not as magic words to sprinkle everywhere. Use your main keyword naturally in the key places below, cover related terms and questions that fully address the topic, and focus on being the best answer.
That is how keywords help today: as signals of relevance within genuinely useful, intent matching content.
How to choose your keywords first
Before placing keywords, you need the right ones, so a quick word on choosing them. Start by thinking about what your audience actually searches for to find what you offer, using their words, not your jargon. Look for terms with genuine intent that match your page’s purpose, and favor specific, less competitive phrases when you are starting out, since they are easier to rank for and often convert better.
A keyword tool helps you find options and gauge demand, but even free methods like Google’s own suggestions and related searches reveal what people look for. Pick one primary keyword per page plus a few related terms and questions to cover the topic fully. For the full method, see our tool comparisons like Ahrefs vs Semrush vs Ubersuggest and our guide to keyword tools.
With the right keyword chosen, placement is what comes next.
The 9 placements that matter
Here are the nine places to use your keyword, each with a right and wrong example. Use your keyword naturally in these spots, never forced.
- Title tag: Your page’s title in search. Right: a clear title including the keyword near the start. Wrong: a vague title with no keyword, or the keyword repeated twice.
- H1 heading: The main on page heading. Right: an H1 that includes the keyword naturally. Wrong: a generic H1 like Welcome with no topic signal.
- First 100 words: The opening of your content. Right: mentioning the keyword naturally early so the topic is clear. Wrong: burying the topic under a long unrelated intro.
- H2 subheadings: Your section headings. Right: using the keyword or close variations in a relevant subheading. Wrong: forcing the exact keyword into every heading.
- URL: The page address. Right: a short URL containing the keyword, like the topic in a few words. Wrong: a long URL of random numbers and codes.
- Meta description: The snippet under your title in search. Right: a compelling description including the keyword naturally to earn clicks. Wrong: a keyword stuffed or missing description.
- Image alt text and file names: How you describe images. Right: a descriptive file name and alt text including the keyword where relevant. Wrong: a file named image1 with empty alt text.
- Internal link anchors: The clickable text of links between your pages. Right: descriptive, natural anchor text that includes relevant terms. Wrong: click here, or the exact keyword forced repeatedly.
- Schema where natural: Structured data describing your content. Right: accurate markup that reflects your page and topic. Wrong: fake or irrelevant markup added to game rankings.
Place your keyword thoughtfully in these nine spots, always reading naturally to a human, and you give search engines clear signals without any stuffing.
Are meta keywords important?
No, meta keywords are not important, and this is the one place that does nothing. The meta keywords tag is a piece of code where people used to list a page’s keywords, and it once influenced rankings in the early days of search. However, it was abused so heavily by spammers stuffing it with irrelevant terms that search engines stopped using it long ago.
Google has clearly stated it does not use the meta keywords tag as a ranking factor, and it has been effectively dead for many years. People still ask about it because old tutorials and habits linger, and some tools still show a field for it, which creates confusion. The simple truth is that you can safely ignore the meta keywords tag entirely, since filling it in does nothing for your rankings and could even hand competitors a list of your targets.
Spend your effort on the nine placements that genuinely matter instead.
The character limits everyone quotes do not exist
Almost every guide on this topic tells you to keep titles to about 60 characters and meta descriptions to 155. Google’s own documentation says something different, and the difference changes what you should worry about.
On titles, Google states there is no limit on how long a title element can be, and that the title link is truncated in results as needed, typically to fit the device width. Not to a character count. Width, on the device the person is holding.
On meta descriptions, the same applies: no limit on length, truncated to fit device width.
There is a bigger point buried in the snippet documentation. Google says snippets are primarily created from the page content itself, and that it sometimes uses your meta description only when that would describe the page more accurately. So your meta description is a suggestion, not a slot you fill. Writing one is still worthwhile, but polishing it to exactly 155 characters is optimising for a rule nobody enforces.
What actually costs you the title you wrote is Google rewriting it, and its documentation lists why that happens: the title is vague or incomplete, the visible page text disagrees with it, it is inaccurate about the page, or it is in a different language from the content. Notice that none of those are about length. A title gets replaced because it does not match the page, not because it ran long.
So the practical version of the advice: put the keyword near the front, make the title genuinely describe that page, keep it distinct from your other pages, and make sure the wording matches what a reader actually sees on the page. Then check how it renders on a phone rather than counting characters, because the phone is where the truncation happens.
Primary and secondary keywords are not placed the same way
The nine placements above assume one keyword. In practice you have one primary term and a handful of related ones, and they belong in different places. Treating them as interchangeable is what produces pages that read as though someone was hitting a quota.
The primary keyword goes in the four places that define the page: the title tag, the H1, the URL, and the first hundred words. Those four tell a reader and a crawler what this page is, and they should agree with each other. If your title says one thing and your H1 says another, you have not placed a keyword, you have created a mismatch, which is one of the reasons Google rewrites titles.
Secondary keywords and variations go everywhere else: H2 and H3 subheadings, the body, image alt text, the meta description, internal link anchors. These are where you cover the topic properly rather than repeat yourself.
The practical benefit is that it removes the temptation the nine placement list creates. Once you know only four spots want the exact primary term, the pressure to force it into every heading disappears, and your subheadings can do their actual job of describing what each section contains.
A quick way to check you have it right: read your H2s on their own, as a list. If they make sense as an outline of the topic, you are fine. If they read as the same phrase five times with small changes, you are optimising for a machine that stopped rewarding that years ago.
Keyword placement mistakes
A few common mistakes turn helpful keyword use into harmful over optimization, so avoid them. Keyword stuffing, cramming your keyword into the content as many times as possible, is the classic error, since it reads badly and search engines penalize it, so use your keyword only where it fits naturally. Repeating the exact keyword in every single heading looks forced and unnatural, so vary your headings with related terms and questions instead.
Using exact match keyword anchor text for internal links repeatedly can look manipulative, so keep internal anchors natural and descriptive. Forcing the keyword into places it does not fit, just to tick a box, hurts readability, which ultimately hurts rankings too. Writing for the keyword instead of the reader is the underlying mistake behind all of these.
The rule is simple: use your keyword naturally in the key places, cover the topic fully, and always write for a human first. If your content reads well to a person, your keyword usage is almost certainly fine.
A worked example
Here is a before and after for one page, targeting the keyword best running shoes for beginners. Before optimization, the page had the title Products, an H1 saying Our Shoes, a URL of random characters, no keyword in the opening, images named photo1 and photo2 with empty alt text, and no meta description. It was invisible in search because nothing signaled what it was about.
After optimization, the title became Best Running Shoes for Beginners, the H1 matched the topic naturally, the URL became a short readable version of the keyword, the opening paragraph mentioned the topic within the first sentences, the images were renamed descriptively with helpful alt text, and a clear meta description invited clicks. The subheadings used natural variations like what to look for and top picks rather than forcing the exact keyword everywhere. Nothing was stuffed; the keyword simply appeared naturally in the places that matter.
With these changes, search engines could clearly understand the page, and it became eligible to rank for its target. That is keyword placement done right: clear signals, natural language, and a page that genuinely answers the search.
Do not put the same keyword on two pages
This is the placement mistake that does the most damage and the one least likely to appear on a placement checklist, because it is not about a single page at all.
If two of your pages target the same term, you are competing with yourself. Google picks one of them to show, and it may not pick the one you would have chosen. Worse, the signals you build split between them: links land on both, internal anchors point at both, and neither accumulates enough to outrank a competitor with one strong page.
It usually happens by accident rather than by design. A blog post ranks for a term, then a service page is written targeting the same term. Or five posts over three years each drift towards the same topic from slightly different angles.
How to find it: in Search Console, open the Performance report, filter to a query you care about, then switch to the Pages tab. If several of your own URLs appear for that one query, that is the problem visible in your own data.
How to fix it: decide which page should own the term, then make the others support it rather than compete. Retarget them to a related but distinct query, or merge them into the winner and redirect. Point internal links from the supporting pages at the one you chose. Do not simply delete the losers if they have links or traffic, redirect them.
The rule that prevents it: one page, one primary keyword, and before you write anything new, search your own site for that term to see whether you already covered it.
Keywords versus topics: the modern shift
To use keywords well today, it helps to understand a shift in how SEO works. In the past, SEO was keyword centric: you picked a phrase and repeated it to rank. Now it is topic and intent centric: you pick a subject and aim to cover it so completely and helpfully that you satisfy everyone searching around it, using your main keyword and its natural variations along the way. This is why placing your keyword in the nine spots matters far less than genuinely answering the searcher’s need.
In practice, this means you should still use your primary keyword in the key placements as a clear signal, but you should also naturally include related terms, questions, and synonyms that a thorough treatment of the topic would contain anyway. You do not force these in; they appear naturally when you truly cover the subject. A page written to fully help someone, with the keyword placed sensibly, will almost always use language that matches how people search, without any keyword stuffing.
So think topic first, keyword placement second, and you get both the clear signals and the depth that modern search rewards, which is exactly the balance the nine placements are meant to support rather than replace.
Where to start
Keywords still help SEO, but as signals of relevance within useful, intent matching content, not as words to stuff. Choose one primary keyword per page, then place it naturally in the nine spots that matter: the title, H1, first 100 words, subheadings, URL, meta description, image alt and file names, internal anchors, and schema where natural. Ignore the dead meta keywords tag entirely.
Avoid stuffing, forced repetition, and writing for the keyword instead of the reader. Get this right, and your pages clearly signal their topic to search engines while reading naturally to people, which is exactly what modern SEO rewards.

Frequently asked questions
How many times should I use my keyword?
There is no ideal number of times to use your keyword, and counting is the wrong approach. Use it naturally where it fits, especially in the key places like the title, H1, and opening, then cover the topic fully with related terms. If your content reads well to a person and clearly signals its topic, your keyword usage is fine. Forcing a specific count leads to stuffing, which hurts rather than helps your rankings.
Does keyword density matter?
No, keyword density does not matter as a ranking factor, and chasing a specific percentage is an outdated tactic. Search engines now focus on topics, intent, and quality rather than how often a phrase appears. Trying to hit a density target usually leads to unnatural, stuffed content that reads badly and can hurt rankings. Instead, use your keyword naturally where it fits and focus on thoroughly answering the search intent.
Should keywords be in every heading?
No, keywords should not be forced into every heading, which looks unnatural and over optimized. Use your keyword in a relevant heading or two where it fits naturally, and use related terms, questions, and variations in the others. Headings should describe their sections clearly for readers first. Covering the topic with varied, natural subheadings signals relevance far better than repeating the exact keyword in every heading, which can look manipulative.
Do meta keywords do anything?
No, meta keywords do nothing for SEO. The meta keywords tag was abused by spammers and search engines stopped using it long ago, with Google confirming it is not a ranking factor. You can safely ignore it entirely, and filling it in could even reveal your target keywords to competitors. Focus instead on the placements that genuinely matter, like the title, headings, content, and URL, rather than the dead meta keywords tag.
Where is the most important place for a keyword?
The title tag is generally the most important place for your keyword, since it strongly signals your page’s topic to search engines and appears as the clickable headline in results. The H1 heading and the opening content are close behind. Including your keyword naturally in the title, near the start, gives the clearest relevance signal, though all nine placements work together, and none should come at the cost of natural, readable content.
How long should a title tag be?
Google states there is no limit on title length. Its documentation says the title link is truncated in results as needed, typically to fit the device width, rather than to a character count. The 60 character figure everyone quotes is a rough guide to what tends to fit, not a rule. What actually gets your title replaced is Google deciding it is vague, inaccurate or inconsistent with the visible page text.
Does Google always use my meta description?
No. Google says snippets are primarily created from the page content itself, and that it sometimes uses your meta description only when doing so would describe the page more accurately. Treat the description as a suggestion worth writing rather than a field that is guaranteed to appear, and do not spend time trimming it to an exact character count.
Can I use the same keyword on more than one page?
You should not. Two pages targeting one term compete with each other, Google picks one and may not pick the one you wanted, and your links and internal anchors split between them so neither gets strong. Find it in Search Console by filtering the Performance report to that query and switching to the Pages tab: if several of your URLs appear, you have the problem. Pick one page to own the term and retarget or merge the rest.
Where does the primary keyword go versus secondary ones?
The primary term belongs in four places that define the page: the title tag, the H1, the URL and the first hundred words, and those four should agree with each other. Secondary keywords and variations go in subheadings, body copy, image alt text, the meta description and internal link anchors. Knowing only four spots want the exact term removes the urge to force it into every heading.
