SEO in 2026 is about speed, structure, and user experience. Here's everything you need to check off to give your site the best chance at ranking.

## Technical SEO Foundations

- **HTTPS everywhere**: SSL is table stakes. Google won't rank insecure sites.
- **Fast Core Web Vitals**: LCP under 2.5s, FID under 100ms, CLS under 0.1.
- **Mobile-first indexing**: Google indexes mobile versions first. Your mobile site IS your site.
- **Clean URL structure**: Use descriptive, keyword-rich URLs. Avoid query parameters.
- **XML sitemap**: Submit to Google Search Console. Keep it updated.
- **robots.txt**: Block what shouldn't be indexed (admin pages, API routes).

## On-Page SEO

- **Unique title tags**: Every page needs a unique, descriptive title under 60 characters.
- **Meta descriptions**: Compelling descriptions under 155 characters that encourage clicks.
- **Heading hierarchy**: One H1 per page, logical H2-H6 structure.
- **Internal linking**: Connect related pages. Use descriptive anchor text.
- **Image optimization**: Alt text, compressed formats (WebP/AVIF), lazy loading.

## Structured Data

Structured data helps Google understand your content and can earn you rich results (FAQ dropdowns, star ratings, breadcrumbs).

- **Organization schema**: Tell Google who you are.
- **LocalBusiness schema**: Essential for local SEO.
- **BreadcrumbList schema**: Helps navigation in search results.
- **FAQPage schema**: Can earn expanded FAQ snippets in search.
- **Article schema**: For blog posts and news content.

## Content Strategy

- **Target long-tail keywords**: Less competition, higher intent.
- **Answer real questions**: Use tools like "People Also Ask" for content ideas.
- **Update old content**: Fresh content ranks better. Review quarterly.
- **Build topical authority**: Create clusters of related content around your core topics.

## The Bottom Line

SEO isn't a one-time project. It's an ongoing practice. But getting the fundamentals right from day one gives you a massive advantage over competitors who treat it as an afterthought.
