On-Page SEO Checklist: 25 Essentials to Rank in 2025

1) Foundation: Intent, Keywords, Structure

Start with the searcher’s intent. Identify a primary keyword (exact query) and 3–6 closely related subtopics. Outline your headers to mirror user questions and SERP structure: H1 for the core topic, H2s for major sections, H3s for steps/examples/FAQs. Keep reading momentum high with short paragraphs, clear subheadings, and actionable examples.

2) Titles and Meta Descriptions

• Place the primary keyword early in the title; keep under ~60 characters.
• Write a unique meta description (145–160 chars) with a benefit + CTA.
• Use brackets, numbers, or years to increase SERP CTR when appropriate.

3) Headers and Content Signals

• Use one H1 that matches search intent; break content with descriptive H2/H3s.
• Answer People Also Ask questions inline with concise paragraphs.
• Add a scannable introduction and a summary section for AI overviews.

4) Internal Links and Navigation

• Link to 3–5 relevant pages with descriptive, natural anchor text.
• Add a related-articles block near the end to extend session depth.
• Ensure breadcrumb navigation exists and is marked up with schema.

5) Media: Images, Alt Text, and Captions

• Compress images, define width/height, and lazy-load below the fold.
• Write meaningful alt text using topic terminology (avoid keyword stuffing).
• Use charts or diagrams where they clarify complex concepts.

6) Structured Data

Add Article schema for posts and Product/FAQ/Breadcrumb schema where relevant. Use JSON-LD. Validate with Google’s rich results tester. Structured data makes your content machine-readable for AI and increases chances of rich snippets.

7) Page Experience and Core Web Vitals

• Optimize LCP: prioritize hero text/image, preconnect critical domains.
• Reduce CLS: set fixed dimensions for media, avoid layout-shifting UI.
• Improve INP: defer non-critical JS, minimize long tasks, avoid heavy widgets.

8) Canonicals and Indexing

• Set correct canonical URLs for paginated/category pages.
• Check robots meta; avoid accidental noindex on important URLs.
• Submit/refresh sitemaps in Google Search Console after major updates.

9) E-E-A-T and Trust

• Show author details, credentials, and last updated dates.
• Add references/citations for data or claims, where helpful.
• Link to About, Contact, and editorial policies to strengthen trust.

10) Quick Win Checklist

• Primary keyword in title, H1, first 100 words.
• Unique meta, clear intent match, TOC for long posts.
• 3–5 internal links; compressed, descriptive images.
• Article/FAQ/Breadcrumb schema where relevant.
• Good CWV: fast LCP, stable layout, responsive interactions.
