🔍 What is SEO?
SEO stands for Search Engine Optimization — it’s the process of improving your website so it ranks higher on search engines like Google.
When someone searches for something like:
“Best mobile phones under ₹20,000”
— Google shows the most relevant, useful, and optimized pages on the first page.

👉 Get your content into those top results — without paying for ads.
🚦The 3 Core Types of SEO You Must Know
1️⃣ On-Page SEO
2️⃣ Off-Page SEO
3️⃣ Technical SEO
Let’s break them down one by one.
1️⃣ On-Page SEO – What You Do On Your Website
On-page SEO is all about making your content and structure better for both users and Google.
✅ Key elements:
- Keyword research – Use words people actually search for
- Title tag – The clickable headline in Google search
- Meta description – A short summary below the title
- URL structure – Clean and readable links (like example.com/seo-tips)
- Headings (H1, H2, H3) – Organize your content with clear titles
- Internal links – Link to other pages on your site
- Image alt tags – Help Google understand your images
- Mobile-friendliness – Your site must work well on phones
- Content quality – Write for humans, not just search engines
📌 Example: A blog titled “Top 10 Budget Cameras for Beginners”
- Uses keywords
- Has internal links to related blogs
- Includes product images with alt tags
- Loads fast and looks great on mobile
2️⃣ Off-Page SEO – What Happens Outside Your Website
Off-page SEO is how the rest of the internet sees your site — mostly through links and social signals.
✅ Key elements:
- Backlinks – Other websites linking to yours (this builds trust)
- Guest posts – Writing on others’ blogs and linking back to your site
- Social shares – People sharing your content on social media
- Brand mentions – Even without a link, mentions of your brand help
- Influencer collaborations – Boost authority and visibility
📌 Example:
If a popular blog links to your website in their article, Google sees that as a vote of confidence and may rank you higher.
3️⃣ Technical SEO – Behind-the-Scenes Stuff
This is where things get a little geeky — but don’t worry, you don’t need to be a developer to understand it.
Technical SEO ensures that:
- Your site is fast 🚀
- Google can crawl and index it correctly 🕷️
- It’s mobile-optimized 📱
- There are no broken links or errors ❌
- You have a sitemap and robots.txt ✅
✅ Tools to help:
- Google Search Console (free)
- Screaming Frog (site audit)
- GTmetrix / PageSpeed Insights (site speed)
- Yoast SEO / Rank Math (for WordPress)
📌 Example:
A slow-loading site with broken links and no mobile version will struggle to rank, even with great content.
🧠 Summary: How They Work Together
| Type of SEO | Focuses On | Your Job |
| On-Page SEO | Content & keywords | Write smart, structured content |
| Off-Page SEO | Backlinks & reputation | Build authority with links |
| Technical SEO | Speed, crawling, indexing | Fix backend errors, improve site health |
✅ Task for Today
Pick a blog or product page on your site (or choose any popular blog). Check:
- Does it use clear headings?
- Is there a main keyword?
- Are there internal links?
- How fast does it load?
- Can you spot a backlink?
This is how you train your SEO brain 🧠
