On-Page SEO
"Where do I put my keywords?" deserves a precise answer, because both failure modes are expensive: too casual and the page never clearly claims its query; too mechanical and it reads like 2009 spam. The truth is that keyword placement is a short, finite checklist — a handful of locations where the phrase genuinely matters — after which repetition adds nothing and subtracts plenty. Here's the exact map.
The placements that matter, ranked
1. Title tag — front-loaded
The heaviest placement on the page, keyword as early as the phrasing allows — the full craft is in the title guide. If you optimise exactly one location, it's this one.
2. H1
The on-page confirmation of the title's promise, keyword included — normally free, since the H1 is usually the title restated. See the headings guide for the hierarchy around it.
3. The first ~100 words
State the topic plainly in the opening — the keyword (or a natural close variant) in the first paragraph confirms the match for scanners and parsers alike. Notice this article did it in sentence one; every article in this series does.
4. URL slug — once, at creation
Per the URL rules: the topic in 2–5 words, decided at birth, never churned.
5. One or two H2s — where the section earns it
Subheadings covering the keyword's core aspects naturally contain it or its variants ("Title tag optimization rules", "How long should a title tag be"). Forcing it into every heading is the classic stuffing tell — headings serve the outline first.
6. Naturally thereafter — variants included
After the checklist above, use the phrase and its natural variations as prose demands and no more. Plurals, reorderings, synonyms all count — the semantic reality is that modern matching reads meaning, not string repetition.
7. Supporting locations, honestly weighted
Meta description: for the SERP bolding, per the CTR guide — no ranking weight. Image alt text: when the image genuinely depicts the topic, per image SEO. Internal anchors pointing here: the placement everyone forgets — other pages introducing this one with descriptive internal anchors is keyword placement from outside, and it's scrutiny-free where external anchors aren't.
What the map deliberately omits
The meta keywords tag (dead since 2009 — Google never reads it), keyword-stuffed footers, hidden text of any flavour, and "sprinkle it every 100 words" density rituals — the counting superstition gets its own burial next in the series. Also omitted: bolding keywords for SEO (bold for readers; parsers don't care) and exact-match domain worship (a relic with its own graveyard).
The intent layer above placement
Placement confirms a match; it cannot create one. A page whose content answers a different intent than the keyword's SERP shows — a product page against informational results — will not rank via placement discipline, and a page that nails the intent ranks with imperfect placement constantly. Run the match-then-merit order: intent first (what shape of page wins this query?), coverage second (every subtopic a competent answer includes), placement third (this checklist, fifteen minutes at most). Placement is the confirmation pass, not the strategy.
The 15-minute placement audit
For any existing page: keyword in title (front half)? In H1? In the first paragraph? In the slug? In 1–2 H2s where honest? Do at least three other pages link here with descriptive anchors? Fix what's missing, touch nothing else, and resist the urge to "add a few more mentions" — if all seven boxes tick and rankings still lag, the gap is content depth or the off-page entry fee, never an eighth mention.
Frequently asked questions
How many times should the keyword appear in total?
However many the checklist plus natural prose produces — typically a handful of times per thousand words, uncounted. The moment you're counting, you've left SEO and entered superstition; the density article retires the maths formally.
Exact match or variations?
Exact where it reads naturally (title, H1), variations everywhere else, freely. Matching systems normalise word order, plurals and synonyms — rigid exact-match repetition is a legibility cost with no matching benefit.
Do keywords in the first sentence specifically matter?
The first ~100 words is the meaningful window, not sentence one specifically — early confirmation, not ritual position. Write the strongest opening; place the phrase where it lands naturally within it. And when placement's done and the ceiling holds, the lever is authority — the website database side of the equation, ours to help with.
