On-page SEO Checklist: 15 Things to Do Before Publishing Any Post

1. Keyword Research and Targeting

Before writing a single word, invest time in proper keyword research. This forms the foundation of your entire SEO strategy. Use tools like Google Keyword Planner, SEMrush, or Ahrefs to identify keywords your target audience is searching for.

Focus on keywords with 10-100 monthly searches when starting out. These long-tail keywords are easier to rank for than highly competitive terms. For example, “how to improve WordPress site speed” is more achievable than “WordPress tips.”

• Identify your primary keyword and 3-5 secondary keywords
• Check keyword difficulty score (aim for 15-30 if new to SEO)
• Analyze top-ranking pages to understand search intent
• Consider user intent: informational, navigational, or transactional

2. Optimize Your Title Tag

Your title tag appears in search results and browser tabs. Keep it between 50-60 characters to prevent truncation. Include your primary keyword naturally within the first 60 characters.

According to SEMrush’s 2023 research, title tags with the primary keyword in the first three words have higher click-through rates. Structure your title effectively:

• Primary Keyword | Modifier | Brand Name (Example: “On-page SEO Checklist: 15 Tips | Complete Guide | WebMarketingPro”)
• Place your most important keyword first
• Add power words like “complete,” “ultimate,” or “essential”
• Include the current year for timely content

3. Write a Compelling Meta Description

The meta description is your pitch to searchers. While it doesn‘t directly impact rankings, it influences click-through rates. Write 150-160 characters to avoid truncation on mobile devices.

Your meta description should answer the searcher’s question briefly and include a call-to-action. For example: “Discover 15 essential on-page SEO tactics to implement before publishing. Learn from experts and boost your search rankings with this complete checklist.”

• Include your primary keyword naturally
• Write in first or second person for engagement
• Create urgency or curiosity (without clickbait)
• Include a clear call-to-action when appropriate

4. Create an SEO-Friendly URL Slug

Your URL slug appears in search results and affects user perception. Use hyphens to separate words, keep it under 75 characters, and include your primary keyword.

• Good: example.com/on-page-seo-checklist
• Bad: example.com/blog-post-123 or example.com/on_page_seo_checklist_15_tips_for_wordpress
• Avoid special characters, numbers, and stop words like “a,” “the,” “and”
• Never change URLs after publishing (use 301 redirects if necessary)

5. Structure Your Headings Properly

Proper heading hierarchy helps search engines understand your content structure. Use only one H1 per page, then organize with H2 and H3 tags logically.

According to HubSpot research, pages with proper heading structure rank 32% better for their target keywords. Your heading structure should look like:

• H1: Main topic (your page title)
• H2: Main sections (your primary keyword should appear once)
• H3: Subsections under H2 (2-3 per H2 maximum)
• Never skip heading levels (don’t go from H1 to H3)

6. Ensure Content Quality and Readability

High-quality content is the cornerstone of on-page SEO. Google’s E-A-T principle—Expertise, Authoritativeness, and Trustworthiness—is increasingly important for search rankings.

Aim for comprehensive content that’s longer than competing pages. The average top-ranking page contains approximately 1,800 words, according to Backlinko’s analysis of 912 million articles.

• Write original, valuable content that provides unique insights
• Use short paragraphs (2-3 sentences maximum)
• Break content into scannable sections with bullet points
• Maintain a conversational tone while remaining professional
• Include real data, statistics, and case studies when possible

7. Add Internal Links Strategically

Internal linking distributes page authority, establishes information architecture, and helps search engines discover pages. Include 3-5 internal links per 1,000 words of content.

Use descriptive anchor text that includes relevant keywords, but avoid over-optimization. Link to authoritative pages within your site that provide additional context.

• Link to your most important pages (homepage, cornerstone content)
• Use keyword-rich anchor text like “WordPress SEO guide” instead of “click here”
• Ensure linked pages are contextually relevant
• Open internal links in the same tab (not new tabs)

8. Optimize Images for SEO

Images enhance user experience and provide additional ranking opportunities. Optimize each image for search engines by including descriptive filenames and alt text.

• Use descriptive filenames: “on-page-seo-checklist.png” instead of “image123.png”
• Write descriptive alt text: “Checklist showing 15 on-page SEO tips for WordPress posts”
• Compress images using tools like TinyPNG or ImageOptim
• Use modern formats like WebP for faster loading
• Include images that support your content topic

9. Test Mobile Responsiveness

With 60% of Google searches now happening on mobile devices, mobile responsiveness is non-negotiable. Google uses mobile-first indexing, meaning your mobile version is the primary version crawled and ranked.

Test your page on multiple devices using Google’s Mobile-Friendly Test tool. Ensure:

• Content is readable without horizontal scrolling
• Tap targets (buttons, links) are at least 48×48 pixels
• Text is at least 16px for easy reading
• Forms are easy to complete on mobile devices

10. Check Page Load Speed

Page speed is a confirmed ranking factor. According to Google, pages that load in 3 seconds have 40% higher bounce rates than pages that load in 1 second.

Use Google PageSpeed Insights to analyze your page performance. Aim for a score of 90+. Focus on these Core Web Vitals:

• Largest Contentful Paint (LCP): Should be under 2.5 seconds
• First Input Delay (FID): Should be under 100 milliseconds
• Cumulative Layout Shift (CLS): Should be under 0.1

11. Add Schema Markup

Schema markup helps search engines understand your content better. It can also enable rich snippets in search results, increasing click-through rates by up to 30%.

For blog posts, implement Article schema. Include:

• Headline
• Publication date
