How Each Type Works

On-Page SEO

On-page SEO involves optimizing elements directly on your website to make your content relevant and accessible to both users and search engines. This includes writing high-quality content that answers user queries, using relevant keywords naturally, optimizing title tags and meta descriptions, using proper header hierarchy, adding descriptive image alt text, and creating a logical internal linking structure.

Off-Page SEO

Off-page SEO focuses on external signals that indicate your website's authority and credibility. The primary signal is backlinks—links from other websites pointing to your site. Search engines view backlinks as votes of confidence: the more high-quality backlinks you have, the more authoritative your site appears. Off-page SEO also includes social media mentions, brand mentions, citations, and your overall online reputation.

Technical SEO

Technical SEO ensures search engines can crawl, index, and understand your website effectively. It involves optimizing site speed, ensuring mobile responsiveness, fixing crawl errors, creating proper site structure, submitting XML sitemaps, configuring robots.txt, implementing structured data (schema markup), and ensuring HTTPS security. Technical SEO is foundational—if search engines can't crawl your site properly, other SEO efforts won't matter.

Local SEO

Local SEO optimizes your online presence for location-based searches, helping businesses appear in local search results and Google Maps. Key elements include optimizing your Google Business Profile, ensuring NAP (Name, Address, Phone) consistency across directories, creating location-specific content, building local citations, and earning positive customer reviews. Local SEO is essential for businesses with physical locations or local service areas.

How the 4 Types Work Together

The four types of SEO are interdependent and work best when aligned:

Technical SEO ensures search engines can crawl and index your site.

On-page SEO provides quality content that users and search engines find valuable.

Off-page SEO builds authority signals that search engines use to rank your content.

Local SEO optimizes for location-based visibility (if applicable).

For example: Technical SEO ensures your site is crawlable, on-page SEO creates quality content, off-page SEO builds authority through backlinks, and local SEO helps you appear in location-based searches. All four must work together for optimal search performance.

Priority Order

  1. Start with Technical SEO: Ensure your site is crawlable and fast
  2. Then On-Page SEO: Create quality, relevant content
  3. Build Off-Page SEO: Earn backlinks and build authority
  4. Add Local SEO: If you have a physical location or local service area
