SEO Basics: What Every Website Needs

Search Engine Optimization (SEO) is how you make your website discoverable to people searching for what you offer. While SEO can get complex, the fundamentals are straightforward and will give you a solid foundation for organic traffic growth.

Title Tags and Meta Descriptions

Every page on your site needs a unique, descriptive title tag (under 60 characters) and a compelling meta description (under 160 characters). The title tag appears in browser tabs and search results, while the meta description serves as your page’s “elevator pitch” in search listings. Include your target keyword naturally — don’t stuff it in.

Think of your meta description as ad copy. It should clearly communicate what the page offers and include a reason for the searcher to click. Pages with well-written meta descriptions consistently achieve higher click-through rates.

Heading Structure

Use headings (H1 through H6) to create a clear content hierarchy. Every page should have exactly one H1 tag that describes the page’s main topic. Use H2 tags for major sections and H3 tags for subsections. This structure helps search engines understand your content and improves accessibility for screen reader users.

Your headings should read like an outline of your content. A visitor scanning only the headings should be able to understand what the page covers. This also helps search engines determine topic relevance and may earn you featured snippets in search results.

Page Speed

Google has confirmed that page speed is a ranking factor, and it directly impacts user experience. Aim for a Largest Contentful Paint (LCP) under 2.5 seconds. Static site generators like Astro give you a head start here, since they produce minimal JavaScript by default.

Optimize images by using modern formats (WebP or AVIF), set explicit width and height attributes to prevent layout shifts, and lazy-load images below the fold. Minimize CSS and JavaScript, and use font-display: swap for web fonts to avoid invisible text during loading.

Internal Linking

Internal links help search engines discover and understand the relationships between your pages. Link from your homepage to your most important pages, and from blog posts to related services or other relevant content. Use descriptive anchor text — “learn about our consulting process” is far better than “click here.”

A well-structured internal linking strategy distributes page authority throughout your site and keeps visitors engaged longer, both of which signal quality to search engines.

Schema Markup

Structured data (also called schema markup) helps search engines understand what your content represents. Add Organization schema to your homepage, Article schema to blog posts, and BreadcrumbList schema for navigation. This can earn you rich results in search — star ratings, FAQ dropdowns, breadcrumb trails — which dramatically increase click-through rates.

JSON-LD is the recommended format for schema markup. Place it in a script tag in your page’s head section. Google’s Rich Results Test tool lets you validate your markup before publishing.

Mobile Friendliness

Google uses mobile-first indexing, meaning it primarily uses the mobile version of your site for ranking. Ensure your site is fully responsive, with readable text, tappable buttons, and no horizontal scrolling on mobile devices. Use Google’s Mobile-Friendly Test to check your pages.

These SEO fundamentals are not one-time tasks — they are ongoing practices. Build them into your workflow from the start, and you will create a solid foundation for long-term organic growth.
