Technical SEO helps search engines discover, understand and index the right pages. Start by checking robots directives, XML sitemaps, canonical URLs, status codes, redirects and internal navigation.
What to consider
Make sure important pages have unique titles and descriptions, useful headings and content that matches the search intent. Structured data can provide additional context when it accurately represents visible page content.
Performance, mobile usability and clean URL behavior also matter. Technical SEO should support high-quality content rather than trying to replace it with hidden keywords or excessive markup.
