- Page Speed Optimization: Google's Core Web Vitals now account for 17% of ranking factors (Google, 2023). Tools like PageSpeed Insights identify render-blocking resources and recommend server-side caching.
- Mobile-First Indexing: 60% of organic traffic originates from mobile devices (BrightEdge, 2024). Responsive design and Accelerated Mobile Pages (AMP) frameworks are critical.
- Structured Data Implementation: Schema markup for local businesses can increase click-through rates by 30% (BrightLocal, 2023). JSON-LD formats for products, reviews, and events enhance rich snippets.
Content Strategy: Quality Over Quantity
Content optimization requires balancing user intent with search relevance:
- Keyword Research: Long-tail keywords (e.g., "best organic skincare for sensitive skin") capture 70% of search traffic (Ahrefs, 2024). Tools like SEMrush's Keyword Magic and AnswerThePublic reveal question-based queries.
- Content Freshness: Google prioritizes updated content for evergreen topics. Regularly refresh existing pages with new data and multimedia.
- E-A-T Framework: Expertise (e.g., medical websites citing peer-reviewed studies), Authoritativeness (domain authority metrics), and Trustworthiness (HTTPS, secure payment gateways) are critical for YMYL (Your Money Your Life) niches.
User Experience (UX) Optimization
Search engines now evaluate:
- Core User Metrics: Bounce rate (under 40% ideal), time on page (>3 minutes), and navigation depth (3+ pages per session).
- Accessibility Compliance: WCAG 2.1 standards improve both rankings and inclusivity. Screen reader compatibility and keyboard navigation testing are mandatory for ADA compliance.
- Internal Linking Architecture: Contextual links (e.g., linking product pages to blog guides) can boost page authority by 22% (SEMrush, 2023).

- Transcription and Subtitles: Closed captions improve watch time by 45% (YouTube Analytics).
- Optimized File Formats: MP4 with H.264 encoding ensures compatibility across devices.
- Structured Data for Videos: Use videoObject schema to highlight timestamps and descriptions.
Local SEO: Geolocation Precision

- NAP Consistency: Name, Address, Phone number must match across 10+ directories (Yelp, Yellow Pages).
