Guide On-Page SEO Checklist

TL;DR — On-page SEO is everything on lune page itself que vous contrôler — the title, le contenu, the headings, the liens, the images. The biggest win by far is writing genuinely utile content que réponses ce que the searcher wanted. Après que, obtenir a clair, descriptive title tag, un obvious principal heading, and liens to and from lune page. La plupart of the rest is polish. Don’t waste temps on “ideal keyword density” or counting H1s — ceux aren’t réel.

Ce que on-page SEO is

On-page SEO is the pratique of optimizing the parts of une page vous directement contrôler: the title tag, the corps content, the headings, lien internes, images, the meta description, and données structurées. It’s un of three buckets:

• On-page SEO — lune page itself (ce checklist).
• SEO technique — si moteur de recherches peut explorer, render, and index votre site at tout.
• Off-page SEO — signals from outside votre site, mostly backlinks.

Ce article is the checklist que ties the on-page pieces ensemble and points vous to a complet deep dive pour chaque un.

Comment utiliser ce checklist

Pas every item matters equally, so don’t treat it as a flat to-do liste. Fonctionner top bas:

Do ces on every page (ils en réalité affecter rankings):

1. Écrire genuinely utile content que matches intent. Ce is the big un. Google literally dit compelling, utile content “va probable influence votre website’s presence in résultats de recherche plus que quelconque of the autre suggestions.” Figure out ce que the searcher veut, alors réponse it meilleur que lune pages ranking now.
2. Écrire a unique, descriptive title tag. Dire ce que lune page is à propos de, clearly. Éviter vague étiquettes comme “Home” and don’t repeat the même keyword over and over. Complet guidance in the meta tags deep dive.
3. Utiliser un clair principal heading and a logical structure. An H1 que matches the topic, alors H2s and H3s pour the sections. Details in header tags.
4. Lien to and from lune page. Every page vous care à propos de devrait be lié from au moins un autre page, with descriptive anchor text. Voir lien internes.

Nice to have (valuable, but pas toujours ranking factors):

5. Écrire a compelling meta description. It doesn’t déplacer rankings — it’s votre pitch in the résultat de recherche, so it affecte clicks. (In meta tags.)
6. Optimize votre images — descriptive texte alternatif, sensible filenames, compressed fichiers. Voir image SEO.
7. Ajouter données structurées où it fits. It rend vous eligible pour résultats enrichis (stars, FAQs, recipes). It is pas a ranking boost. Voir données structurées.

The choses personnes obtenir incorrect

A few “rules” vous pouvez safely ignore:

• Multiple H1s are fine, and the H1 isn’t a make-or-break ranking factor. Utiliser headings pour humans; don’t stress the count.
• Là is aucun ideal “keyword density.” Google doesn’t count votre keyword percentage — écrire naturally.
• Meta descriptions don’t rank vous. Ils earn clicks.
• Balisage de données structurées doesn’t rank vous. It earns résultats enrichis.

Vouloir the prioritized, sourced version with the reasoning? Switch to the Avancé tab.

TL;DR — On-page SEO is the définir of controllable, per-page elements — title, content, headings, lien internes, meta description, images, données structurées. The mistake I voir la plupart souvent is treating les as equal-weight checkboxes. They’re pas. Content quality + intent match and title relevance are genuine ranking levers; lien internes réussir PageRank; meta descriptions are a CTR lever, pas a ranking un; données structurées buys rich-result eligibility, pas rankings; and H1 count and keyword density are cargo cult. Ce is the cluster hub — I prioritize ici and route depth to the five deep dives (meta tags, header tags, internal liens, données structurées, image SEO) plutôt que re-teaching les.

Ce que “on-page” en réalité covers

On-page SEO is everything on lune page que vous contrôler directement, as opposed to the technical infrastructure que decides si lune page peut be crawled and indexé at tout, or the off-page signals (mostly liens) que come from elsewhere. The controllable définir: the <title> element, the corps content, the heading structure, lien internes, images, the meta description, and données structurées.

The raison to garder ce liste is que it’s facile to spend an afternoon “optimizing” the incorrect choses. So I sort every item by ce que it fait — réel ranking factor, eligibility, or click-through — and I don’t repeat the depth que déjà lives in the meta tags, header tags, lien internes, données structurées, and image SEO articles. Ce is the map; ceux are the territory.

Tier 1 — foundational (réel ranking impact, do ces everywhere)

1. Utile content que matches search intent. Google is unusually direct que ce outweighs everything sinon on lune page: “Creating content que personnes trouver compelling and utile va probable influence votre website’s presence in search results plus que quelconque of the autre suggestions in ce guide.” Avant vous écrire, match the intent the SERP is rewarding (informational, transactional, navigational) and cover the topic entièrement suffisant que a searcher doesn’t besoin to bounce back pour a second result. Google’s propre helpful-content self-assessment is a usable content checklist in its propre correct — commencer with “Fait le contenu provide original information, reporting, research, or analysis?” If your answer is “aucun, ce is a thinner rewrite of page un,” fix que avant touching anything sinon on ce liste.

2. A unique, descriptive title tag. Google’s guidance: “Écrire descriptive and concise text pour votre <title> elements. Éviter vague descriptors comme ‘Home’ pour votre home page, or ‘Profile’ pour a spécifique person’s profile.” And don’t stuff: “there’s no reason to have the same words or phrases appear multiple times.” The title is un of the on-page elements with genuine ranking weight and it’s a click driver in the SERP, so it’s worth getting correct. Length, truncation, and how Google rewrites titles are tout in the meta tags deep dive.

3. Un clair H1 and a logical heading structure. Utiliser an H1 que matches the page topic, alors H2/H3 pour sections. Ce helps utilisateurs, screen readers, and Google’s understanding of votre structure. Simplement don’t over-invest: from a ranking standpoint, semantic order barely matters (Google: “it doesn’t matter si you’re en utilisant les out of order” pour Search, though it matters a lot pour screen readers). Complet treatment, notamment the multiple-H1 question, in header tags.

4. Lien internes in and out, with descriptive anchors. “Every page vous care à propos de devrait have a lien from au moins un autre page on votre site.” Lien internes are the un on-page element que en réalité moves PageRank autour votre site, so ce is a réel ranking lever, pas simplement navigation. But plus n’est pas automatically meilleur — voir the myths ci-dessous. How to construire a lien structure que concentrates authority on votre money pages is the whole point of the lien internes article.

Tier 2 — high-value, but pas (mostly) ranking factors

5. A compelling meta description. “A bon meta description is short, unique to un particulier page, and inclut the la plupart relevant points of lune page.” It n’est pas a ranking factor — its job is to win the click une fois you’re déjà ranking. Treat it as ad copy. (In meta tags.)

6. Image optimization. Descriptive texte alternatif (qui doubles as accessibility and Google Images context), sensible filenames, and compressed fichiers que don’t drag votre page weight. Texte alternatif is the un image element with a modest direct SEO role; the rest is UX and performances. Voir image SEO.

7. Relevant données structurées. Ajouter schema que matches lune page’s content type (Product, Recipe, FAQPage, Article, and so on). Its valeur is rich-result eligibility and entity understanding — it is pas a ranking factor. I garder ce framing consistent with the données structurées article on objectif, parce que “add schema to rank higher” is un of the la plupart durable myths in SEO. Validate with Google’s Résultats enrichis Tester and you’re fait.

8. E-E-A-T signals. Pour content où trust matters (health, finance, anything YMYL), faire the experience and expertise visible: author bylines with réel credentials, original données or first-hand testing, clair sourcing, accurate dates. Ce isn’t a unique tag vous ajouter; it’s a property of le contenu and le site. It’s aussi the un item on ce checklist sans a dedicated deep dive on le site yet — so treat ce section as the native home pour it.

Tier 3 — supporting signals

9. Page experience / Core Web Vitals. Fast, stable, responsive pages are a tie- breaker and a UX win, pas a principal lever. Plutôt que re-teach LCP/INP/CLS ici, route to the web performances cluster pour the metrics and the fixes.

10. AI-search visibility. As AI Overviews and AI réponse engines prendre plus of the result page, on-page fundamentals (clair structure, direct réponses, entity clarity, extractable passages) increasingly double as AI-search optimization. Go deep in the AI search optimization cluster plutôt que bolting a thin version onto ce page.

11. Featured-snippet formatting. Réponse the obvious question directement and early, utiliser listes and tables où the format fits, and structure sections so a unique passage peut be lifted cleanly. Ce is formatting discipline layered on top of Tier 1’s “match intent and cover the topic.”

Myths to arrêter chasing

Ces waste temps or actively backfire:

1. “The H1 is a major ranking factor / you need exactly one.” John Mueller has said headings aider SEO and accessibility but “aren’t going to faire or break votre site’s rankings,” and que une page peut rank fine with zero or multiple H1s. Utiliser headings pour structure and utilisateurs; don’t audit the count.
2. “There’s an ideal keyword density.” Là isn’t, and là hasn’t been pour bien over a decade. Google evaluates topical relevance with language understanding, pas a keyword-count ratio. Chasing a density target simplement pushes vous toward keyword stuffing — qui the title guidance explicitly warns contre.
3. “Meta descriptions are a ranking factor.” They’re pas. Ils influence click-through from the SERP, complet arrêter.
4. “Schema markup boosts rankings directly.” It doesn’t. It rend vous eligible pour résultats enrichis and helps entity understanding — that’s the entier benefit.
5. “More internal links is always better.” Google: “There’s aucun magical ideal number of liens a donné page devrait contain. Cependant, si vous think it’s aussi beaucoup, alors it probably is.” Relevance and a sane structure beat raw lien count every temps.

A remarque on Bing

Bing’s public guidance leans a little plus literal que Google’s — historically it puts plus weight on keyword matching in titles and headings and donne fairly spécifique length hints pour titles and descriptions, où Google leans on language understanding. It’s a nuance worth knowing si Bing is a meaningful channel pour vous, pas a raison to écrire two différent pages. (I’d vérifier the current Bing Webmaster Guidelines copy directement avant quoting exact character counts — leur aider pages déplacer autour.)

Où to go suivant

Chaque Tier 1–2 item has a complet article:

• Meta tags — title tags and meta descriptions in depth.
• Header tags — H1–H6, how beaucoup ils matter, and the multiple-H1 question.
• Lien internes — building a lien structure que concentrates authority.
• Données structurées — schema pour rich results and entity understanding.
• Image SEO — texte alternatif, filenames, compression, Google Images.

Pour the supporting tiers, the web performances and AI search optimization clusters carry the depth.

AI summary

A condensed prendre on the Avancé version:

• On-page SEO = the per-page elements vous contrôler — title, content, headings, lien internes, meta description, images, données structurées. Distinct from technical SEO (explorer/index) and off-page SEO (liens).
• Prioritize; don’t treat items as equal weight. Sort by ce que chaque un fait: ranking factor vs. eligibility vs. click-through.
• Tier 1 (réel ranking impact): utile content matched to intent (Google: influences presence “more than any of the other suggestions”), a unique descriptive title tag, a clair H1 + logical headings, and lien internes with descriptive anchors (ils réussir PageRank).
• Tier 2 (valuable, pas ranking factors): meta description (a CTR lever), image optimization (texte alternatif is the SEO piece), données structurées (rich-result eligibility, pas rankings), and visible E-E-A-T signals.
• Tier 3 (supporting): Core Web Vitals / page experience, AI-search visibility, featured-snippet formatting.
• Myths to drop: H1 count as a ranking factor, ideal keyword density, meta descriptions ranking vous, schema boosting rankings, and “plus lien internes is toujours meilleur” (Google: aucun magical ideal number).
• Ce is the hub. Depth lives in five deep dives: meta tags, header tags, lien internes, données structurées, image SEO — plus web performances and AI-search optimization pour the supporting tiers.

Fonctionner top bas — the tiers are ordered by impact, pas by how long ils prendre.

Tier 1 — foundational (réel ranking impact)

• Content offers something original — données, testing, analysis, a réel point of view — pas a thinner rewrite of ce que déjà ranks.
• Title tag is unique, descriptive, and pas keyword-stuffed. → meta tags
• Un clair H1 que matches the topic; H2/H3 organize the sections logically. → header tags
• Lune page is lié from au moins un autre relevant page, with descriptive anchor text; lune page liens out to connexe pages. → lien internes

Tier 2 — high-value (pas toujours ranking factors)

• Meta description is written as SERP ad copy (drives clicks, pas rankings). → meta tags
• Images have descriptive texte alternatif, sensible filenames, and are compressed. → image SEO
• Données structurées matches le contenu type and validates in the Résultats enrichis Tester (pour eligibility, pas a ranking boost). → données structurées
• E-E-A-T is visible: author byline, credentials, sourcing, accurate dates.

Tier 3 — supporting signals

Myths — confirmer you’re PAS doing ces

• Pas chasing an “ideal keyword density.”
• Pas auditing H1 count as a ranking factor (multiple H1s are fine).
• Pas treating the meta description as a ranking signal.
• Pas ajout schema expecting a ranking boost.
• Pas ajout lien internes purely to raise the count.

The intent → evidence → clarity framework

1. Intent: identifier the reader task and page objectif avant touching tags.
2. Evidence: faire lune page substantively utile, accurate, and distinct suffisant to deserve indexation.
3. Clarity: express que valeur via a descriptive title, heading structure, lien internes, media, and search-result presentation.

Fonctionner in que order. Polishing metadata ne peut pas rescue une page que misses intent or lacks evidence.

On-page SEO mistakes to éviter

• Treating a checklist score as evidence que lune page satisfies search intent.
• Forcing exact-match phrases into every heading, image, and lien.
• Rewriting titles pour length alone sans preserving meaning and differentiation.
• Ajout schema pour content or entities lune page ne fait pas en réalité contain.
• Fixing low-impact formatting pendant que ignoring weak content, duplicates, or poor internal discovery.
