1. On-Page SEO (Inside Your Website)

This focuses on optimizing content and structure.

Key elements:

• Keywords – Words people search (e.g., “best phones under 20000”)
• Title Tags – The clickable headline in search results
• Meta Description – Short summary of your page
• Headings (H1, H2, H3) – Organize content clearly
• URL Structure – Clean and readable links
• Internal Linking – Linking to your own pages
• Image Optimization – Use alt text and compress images

👉 Example: A blog titled “Best Laptops in India 2026” using proper keywords and headings.

Example:
If someone searches “best shoes in India,” SEO helps your website appear on top.

2. Search Engine Marketing (SEM)

SEM involves paid ads on search engines. You pay to appear at the top of search results.

Example:
Ads you see at the top of search results are usually from platforms like Google Ads.

How SEM Works

When someone searches on Google Search, advertisers bid on keywords. If your bid and ad quality are strong, your ad appears in the results.

Example:
Search “buy smartphone under 20000” → You see sponsored ads at the top. Those are SEM ads.
