Use this checklist to ensure your website meets the latest on-page SEO best practices:


1. Content Optimization

  • Use target keywords naturally in the title, headers, and throughout the content.

  • Write unique, engaging, and high-quality content that matches user intent.

  • Structure content with short paragraphs, bullet points, and subheadings (H1, H2, H3).

  • Incorporate LSI (Latent Semantic Indexing) keywords for semantic relevance.

  • Optimize for featured snippets by answering questions clearly and concisely.


2. Meta Tags

  • Write a unique and compelling meta title (50-60 characters) with the target keyword.

  • Create a meta description (120-155 characters) that includes the primary keyword and a call-to-action.

  • Ensure the meta tags are relevant and descriptive for each page.


3. URL Structure

  • Keep URLs short, clean, and descriptive.

  • Use hyphens (-) to separate words in the URL.

  • Include the primary keyword in the URL.


4. Mobile Optimization

  • Use a responsive design that adjusts seamlessly to all devices.

  • Ensure buttons and links are easy to click on mobile devices.

  • Optimize for Core Web Vitals on mobile, especially loading speed.


5. Technical SEO Elements

  • Include only one H1 tag per page and use it for the main heading.

  • Add descriptive alt text to all images.

  • Compress images to improve load times (use WebP or other next-gen formats).

  • Use a reliable content delivery network (CDN).

  • Minify CSS, JavaScript, and HTML files.


9. User Experience (UX)

    • LCP (Largest Contentful Paint): ≤ 2.5 seconds.

    • FID (First Input Delay): ≤ 100 ms.

    • CLS (Cumulative Layout Shift): ≤ 0.1.
