? What Is SEO (In Developer Terms)?

SEO is the practice of structuring web content and markup so that search engines can easily discover, understand, and rank your pages. It’s not magic — it’s mostly semantic HTML, performance, accessibility, and a bit of common sense.

⚙️ 1. Page Titles and Meta Descriptions

• Title tag: Appears in search results and browser tabs. Keep it under 60 characters.

• Meta description: Summarizes the page (max ~160 characters). Helps improve CTR (click-through rate).

✅ Pro Tip: Make them unique for each page.

2. Semantic HTML Structure

Use the right tags to help Google understand your content:

Use one

per page

Nest headings logically:

under

, then

under

Use

3. URLs & Canonical Tags Keep URLs short, descriptive, and lowercase: ✅

/blog/basic-seo-tips ❌
/post?id=1234

To avoid duplicate content issues, use the canonical tag:

robots.txt

User-agent: *
