SEO Basics (for developers)
Get the fundamentals right first: meta tags, OG tags, canonical URLs, robots.txt and sitemaps.
1) Must-have meta: title / description / canonical
Title and description shape your SERP snippet. Canonical tells search engines which URL is the primary version.
html
<title>Free SEO Tools - SEO Academy</title>
<meta name="description" content="Free SEO tools and developer-focused tutorials for SEO/AEO." />
<link rel="canonical" href="https://seo.lucas-futures.com/en" />2) Sharing previews: Open Graph / Twitter
OG/Twitter tags don’t directly boost rankings, but they improve click-through and sharing — great for tool pages.
html
<meta property="og:type" content="website" />
<meta property="og:title" content="Meta Tags Generator" />
<meta property="og:description" content="Generate SEO meta tags in seconds." />
<meta property="og:image" content="https://seo.lucas-futures.com/og-image.png" />3) robots.txt and sitemap: crawling vs discovery
- robots.txt: don’t block critical CSS/JS needed for rendering
- sitemap: include canonical URLs you want indexed (avoid noindex URLs)
- Submit to Search Console and monitor coverage/indexing
