On-Page SEO for Bloggers: Complete Checklist to Rank in 2025

On-page SEO is one of the most important factors for getting organic traffic to your blog — and organic traffic is what AdSense reviewers want to see. This comprehensive checklist covers every on-page SEO element you need to optimize before publishing any blog post in 2025.

Title Tag (H1)

• Include your primary keyword in the title, preferably at the beginning
• Keep title under 60 characters to avoid truncation in search results
• Make it compelling and specific (numbers and power words improve CTR)
• Use only one H1 per page

Meta Description

• Write a unique meta description for every page and post
• Include the target keyword naturally within the description
• Keep between 150-160 characters
• Write it as a call-to-action that entices users to click
• Don't duplicate meta descriptions across multiple pages

URL Structure

• Use short, readable URLs that include the keyword
• Use hyphens (not underscores) between words
• Avoid dates, numbers, and category prefixes if possible
• Example: /blog/adsense-approval-checklist (good) vs /blog/?p=1234 (bad)

Header Tags (H2, H3, H4)

• Use H2 for main section headings, H3 for subsections
• Include secondary keywords and LSI terms naturally in headers
• Don't skip heading levels (H1 → H3 without H2)
• Keep headings descriptive and reader-friendly, not keyword-stuffed

Content Optimization

• Target one primary keyword and 3-5 secondary/related keywords per article
• Use the primary keyword in: title, intro paragraph, at least one H2, and conclusion
• Maintain keyword density of 1-2% (don't stuff)
• Use synonyms and natural language variations throughout
• Cover the topic comprehensively — answer every question a reader might have
• Aim for 1,500+ words for competitive keywords

Image Optimization

• Add descriptive ALT text to every image (include keyword where natural)
• Use descriptive filenames: "adsense-approval-checklist.jpg" not "image123.jpg"
• Compress images before uploading (aim for under 100KB)
• Add loading="lazy" to images below the fold
• Include title attribute for additional context

Internal Linking

• Link to 3-5 related articles from every new post you publish
• Use descriptive anchor text that tells readers what they'll find (not "click here")
• Link to your most important pages (pillar content) from multiple posts
• Ensure no "orphan pages" (pages with no internal links pointing to them)

Schema Markup (Structured Data)

• Add Article schema to all blog posts (includes author, date, publisher)
• Add FAQPage schema to FAQ sections within posts
• Add HowTo schema to step-by-step tutorial posts
• Validate with Google's Rich Results Test tool

Technical On-Page Elements

• Canonical tag pointing to the correct URL (prevents duplicate content)
• robots meta tag (index, follow for all content pages)
• Open Graph meta tags for social sharing
• Twitter Card meta tags
• Breadcrumb navigation markup
