Let’s now focus on what you can control 100% — your site’s structure, layout, keywords, and performance.
🔍 What is On-Page SEO?
On-Page SEO refers to everything you do within your website or blog to improve how well it ranks on search engines like Google, Bing, and even YouTube.
It includes:
- Choosing the right layout
- Keyword usage in your content
- URL structure
- Internal linking
- Image optimization
- Page speed
- Mobile responsiveness
- Structured data & accessibility
Let’s go through these step-by-step with actionable examples.
🎨 Step 1: Choose an SEO-Optimized Theme or Layout
Your website theme is the foundation of your SEO.
✅ What to Look For in a Good Theme:
- Fast loading speed (under 3s)
- Responsive on all devices
- Clean HTML markup with proper
<h1>,<h2>, etc. - Minimal JavaScript & unnecessary animations
Example (Blogger or WordPress):
If using Blogger:
<h1>On-Page SEO for Developers</h1>
<h2>Image Optimization Tips</h2>
Use tools like Lighthouse or PageSpeed Insights to test your theme speed and performance.
⚠️ Avoid fancy animations and sliders unless they’re lazy-loaded and lightweight.
📈 Step 2: Use Google Trends to Discover Hot Keywords
Before writing your next post, check what’s trending in your niche.
🔍 Google Trends Keyword Workflow:
- Go to https://trends.google.com
- Search your topic (e.g., “AI resume tools”)
- Filter by country and time range
- Note related queries and rising terms
Use these insights to create titles and headers:
<h1>Top AI Resume Builders for Developers (2025)</h1>
✅ Long-tail keywords (e.g., “best SEO plugin for Blogger 2025”) have lower competition and rank faster.
🔗 Step 3: Master Internal Linking for Better Engagement
Internal links help:
- Search engines crawl your site more effectively
- Readers navigate related posts
- Older posts stay relevant
🧩 Example:
<p>Want to improve your off-page strategy too? <a href="/2025/07/off-page-seo-strategies-for-backlinks-2025.html">Check our Off-Page SEO guide</a></p>
Use descriptive anchor text, not “click here”.
🔁 Every new post should link to at least 2–3 older posts for max SEO benefit.
🖼️ Step 4: Optimize Images with Alt Tags and Descriptive Filenames
Google doesn’t “see” images — it reads the alt text and file name.
HTML Image Example:
<img src="on-page-seo-2025-guide.jpg" alt="2025 On-Page SEO Optimization for Bloggers" />
Tips:
- Use hyphens in file names (

- Add captions where appropriate
💡 Bonus: Use WebP format to reduce image size without quality loss.
🗺️ Step 5: Create and Submit Your Sitemap
Sitemaps help search engines discover your content faster.
🛠️ Generate a Sitemap:
- Go to: https://www.xml-sitemaps.com
- Enter your blog or website URL
- Download the
sitemap.xmlfile
📩 Submit It:
- Go to Google Search Console
- Choose your site
- Paste your sitemap URL (e.g.,
yoursite.com/sitemap.xml)
🔁 Update your sitemap whenever you publish new pages/posts.
⚙️ Step 6: Structure Content with H1, H2, H3 Tags
Proper use of headings helps both readers and bots understand your content.
Example:
<h1>Complete On-Page SEO Guide for 2025</h1>
<h2>1. Optimize Image Alt Text</h2>
<h3>Why Alt Text Matters for Search Engines</h3>
⚠️ Only one
<h1>per page. Use H2s for main sections, H3s for sub-sections.
🚀 Step 7: Use an SEO Checklist (Before You Publish)
Here's a fast checklist to apply before hitting “Publish”:
- ✅ Short, keyword-rich permalink (e.g.,
/on-page-seo-2025) - ✅ Keyword in: title, first paragraph, last paragraph
- ✅ Only one H1 tag
- ✅ All images have alt tags
- ✅ Meta description under 155 characters
- ✅ Internal links to at least 2 older posts
- ✅ External links to trusted sources
- ✅ Page loads in under 3 seconds
- ✅ Mobile responsive design
