SEO cơ bản

Plain-language guides on how search engines find, read and show your pages. We cover titles and descriptions, headings, internal links, redirects, sitemaps, robots.txt and noindex rules. Every article starts from a real finding in a website audit and ends with a fix you can apply yourself. The goal is not tricks but a site that search engines understand without effort. Examples come from small business websites, online shops and agency projects. Read these guides before you publish new pages or redesign an old site.
