SEO for Developers — The Technical Checklist That Matters

Developers control the SEO factors that matter most. This is the technical layer — what to put in every page you ship.

Per-page essentials

<title>Primary Keyword — Brand (under 60 chars)</title>
<meta name="description" content="~155 chars — this is your ad in Google results">
<link rel="canonical" href="https://site.com/page">
<meta property="og:title" content="...">   <!-- social/WhatsApp shares -->
<meta property="og:image" content="...">

Structure Google reads

• One h1 with the main keyword; h2s for sections (crawlers weight headings)
• Semantic tags — <main> <article> <nav> map your page for the crawler
• Descriptive URLs: /tcs-nqt-preparation-guide not /page?id=7
• Internal links between related pages — crawl paths + authority flow

Site level

• sitemap.xml submitted in Google Search Console; robots.txt not blocking assets
• JSON-LD structured data (Article, FAQPage, HowTo) → rich results
• HTTPS, mobile-friendly, Core Web Vitals green

Every page of this site follows this checklist — view source on any page and compare.
