Why Checklists Still Matter

Even experts miss details. A checklist isn't about following rules; it's about ensuring quality consistency. In 2025, "On-Page" includes Performance and Accessibility.

  • Clear H1 with the core value proposition.
  • Short intro that frames the problem and solution.
  • Descriptive subheadings; avoid keyword stuffing.
  • One primary CTA visible above the fold.

1. The "Meta" Layer (Invisible to User)

  • Title Tag: 50-60 characters. Must match intent.
    • Bad: "Home - Tekibo"
    • Good: "Tekibo - Automated SEO Reports for Agencies"
  • Meta Description: 150-160 characters. Must include a CTA.
    • Example: "Generate client reports in 30 seconds. No credit card required. Start your free trial today."
  • Canonical Tag: Ensure it points to the primary version of the URL.
  • Open Graph (OG) Image: Size 1200x630. Does it look good on Twitter/Slack?

2. The "Content" Layer (Visible)

  • H1 Tag: Only ONE per page. Matches the Title Tag (mostly).
  • URL Structure: Short, lowercase, hyphens.
    • Bad: /blog/2025/12/04/seo_tips_v2
    • Good: /blog/seo-tips
  • First 100 Words: Does it answer the user's query? (See our GEO guide).
  • Readability: Use short paragraphs (2-3 sentences). Use bullet points.
  • Images:
    • Filename: descriptive-name.jpg
    • Alt Text: Describes the image content for screen readers (and Google).

3. The "Technical" Layer (Performance)

  • Core Web Vitals:
    • LCP (Largest Contentful Paint): < 2.5s. (Is your hero image preloaded?)
    • CLS (Cumulative Layout Shift): < 0.1. (Do images have height/width attributes?)
    • INP (Interaction to Next Paint): < 200ms. (Is your JS blocking the main thread?)
  • Mobile Friendly: Check tap targets (buttons must be > 44px).
  • HTTPS: Secure connection is mandatory.

4. The "Engagement" Layer (UX)

  • Table of Contents: For long posts (>1500 words), give users a map.
  • Breadcrumbs: Let users go back up the hierarchy.
  • External Links: Link to 2-3 authoritative sources. Open in new tab (target="_blank").
  • Internal Links: Link to 2-3 relevant pages on your site.

5. The "Conversion" Layer (Revenue)

  • Primary CTA: Is it sticky? Is it distinct?
  • Exit Intent: Do you have a mechanism to catch users leaving?
  • Social Proof: Is there a testimonial or logo bar visible?

Case Study: Fixing a "Perfect" Blog Post

The Issue: A client wrote an amazing 3,000-word guide. It ranked #5 but converted at 0.1%.

The Audit:

  1. The CTA was at the very bottom.
  2. The images were 5MB each (slow load = high bounce).
  3. No Table of Contents (hard to navigate).

The Fix:

  1. Added a "Key Takeaways" box at the top.
  2. Added a "Get the PDF" CTA in the sidebar.
  3. Compressed images to WebP.

The Result: Rank #2. Conversion rate 1.5% (15x increase).

FAQ: On-Page SEO

Q: Does word count matter? A: No. "Depth" matters. If you can answer the question better in 500 words than a competitor does in 2,000, you win.

Q: How important is keyword density? A: Irrelevant. Don't count keywords. Write naturally. Google understands synonyms.

Q: What is the most common mistake? A: Slow page speed. If your site takes 5 seconds to load on 4G, no one will see your perfect SEO.
