Why Image SEO Matters for Blogger Ranking?
Image SEO does not mean your image will rank only because you added one keyword. The real work is to make the image useful, relevant and easy to understand.
| Image SEO Factor | How It Helps | Real Benefit |
|---|---|---|
| Alt text | Explains image meaning. | Helps search engines and screen readers. |
| File name | Gives image topic context. | Better than random file names. |
| Compression | Reduces file size. | Improves loading speed. |
| Relevant placement | Image stays near related text. | Improves topic clarity. |
| Responsive size | Works better on mobile and desktop. | Improves user experience. |
How to Write Alt Text for Blogger Images?
Alt text is a short description that explains what an image is about. It should be useful and natural, not stuffed with keywords.
Describe the Image
Write what the image actually shows in simple words.
Add Context
Connect the alt text with the topic of your article.
Keep It Short
Do not write a full paragraph. One clear line is enough.
Avoid Keyword Stuffing
Do not repeat the same keyword again and again.
Good vs Bad Alt Text Examples
Alt text should be clear, useful and related to the image. These examples will help you understand better.
| Image Topic | Bad Alt Text | Good Alt Text |
|---|---|---|

| Blog post thumbnail | best image for blog post | Blog post thumbnail with title text and website branding. |
Best Image File Name for Blogger SEO
Before uploading an image to Blogger, rename the file properly. Random names like IMG_20260101.png or Screenshot_123.jpg do not explain the image topic.
Best file name format: main-topic-keyword-short-description.jpg
| Bad File Name | Good File Name | Why Better? |
|---|---|---|
| IMG_9988.jpg | blogger-image-seo-guide.jpg | Clear topic and readable name. |

Best Image Size for Blogger Posts
Image size depends on your blog layout, but you should avoid uploading very large images without need. Large images slow down the page and make mobile loading poor.
| Image Type | Suggested Width | Best Use |
|---|---|---|
| Blog thumbnail | 1200px to 1600px | Good for featured images and social sharing. |
| In-article screenshot | 800px to 1200px | Good for tutorials and step guides. |
| Small graphic | 600px to 900px | Good for icons, small examples and visual blocks. |
| Mobile-focused image | 720px to 1080px | Good for mobile-first articles. |
How to Compress Images for Blogger?
Image compression means reducing image file size while keeping quality acceptable. This is important because heavy images make your Blogger post slow.
Resize First
Reduce image width according to your blog layout before compression.
Choose Right Format
Use JPG for photos, PNG for graphics with text, and WebP when supported.
Compress Carefully
Reduce file size, but do not make text blurry or unreadable.
Check Final Size
Try to keep normal blog images lightweight, especially for mobile users.
Best Image Format for Blogger: JPG, PNG or WebP?
Choosing the right image format also matters. Every format has a different use.
| Format | Best For | Advice |
|---|---|---|
| JPG / JPEG | Photos and thumbnails | Good balance of quality and file size. |
| PNG | Graphics, text images and transparent images | Clear quality, but file size can be high. |
| WebP | Modern compressed images | Good for speed if your workflow supports it properly. |
| SVG | Logos and simple vector graphics | Useful for clean icons and scalable designs. |
How to Add Alt Text in Blogger Step by Step
Adding alt text in Blogger is simple. Do it before publishing the post.
Upload Image
Open Blogger post editor and upload your image inside the article.
Click Image
Click on the uploaded image inside the Blogger editor.
Open Settings
Open image settings or properties option depending on your Blogger editor view.
Add Alt Text
Write a short and meaningful description of the image.
Add Title Text
Use a clean title if the option is available, but do not stuff keywords.
Preview Post
Preview your post and check that image looks clear on mobile and desktop.
SEO-Friendly Image HTML Example
If you are adding image code manually in Blogger HTML view, use a clean structure like this.
Image Placement Tips for Better SEO
Image placement is also important. Do not add images randomly. Put images near the text where they are actually useful.
- Place images close to the related paragraph.
- Add clear captions if the image needs explanation.
- Do not upload decorative images again and again.
- Use screenshots only when they help users understand steps.
- Keep important text readable inside image thumbnails.
- Use your website branding in thumbnails when needed.
- Check image layout on mobile before publishing.
Lazy Loading Images in Blogger
Lazy loading means images load when users are about to see them. This can improve performance, especially on long articles with many images.
Simple example: Use loading="lazy" in image HTML when you manually add images below the first screen area.
But do not use lazy loading in a broken way. If images are hidden from search engines or users, it can create issues. Always test your page after adding lazy loading.
Common Blogger Image SEO Mistakes
Many beginners make small image mistakes that reduce quality and page speed. Avoid these problems:
- Uploading images with random file names.
- Leaving alt text empty for important images.
- Stuffing keywords inside alt text.
- Uploading very large uncompressed images.
- Using blurry thumbnails.
- Adding images that are not related to the article.
- Using the same image alt text everywhere.
- Putting too many heavy images in one post.
- Not checking mobile view after publishing.
Final Conclusion
Blogger Image SEO is a simple but powerful part of blog optimization. If your images have proper file names, helpful alt text, correct size and compression, your post becomes more user-friendly and professional.
The best method is simple: rename images before upload, resize them according to your blog layout, compress them properly, add meaningful alt text and place images near relevant text.
Image SEO alone will not rank your article, but it improves page quality, speed, accessibility and user experience. When you combine it with helpful content, good title, clean permalink, search description and internal links, your Blogger post becomes much stronger.
