Key Elements of Image SEO That Marketers Must Know
Let’s break it down step by step.
1. Choose the Right File Format
The file type affects both quality and load speed.
→ Tip: Use WebP wherever possible for better speed.
2. Compress Your Images
Compression minimizes size of files without the loss of quality.
- Tools to use: TinyPNG, CompressJPEG, Squoosh or ShortPixel.
- CMS Plugins: Smush (WordPress), EWWW Image Optimizer.
Example:
- An uncompressed JPEG = 2MB.
- After compression = 200KB.
- → Loads 10x faster!

Google reads image file names. Instead of IMG1234.jpg, name it:
- blue-running-shoes.jpg
- seo-report-graph.png
→ This enables Google to know what the image is all about.
4. Add Alt Text Correctly
Alt Text (Alternative Text) is vital for:
- SEO (Google uses it to understand images).
- Accessibility (screen readers for visually impaired users).
Good Alt Text Example:
- "Red sports car parked on city street"
Bad Example:
- "image123.jpg" or "photo"
- → Keep it descriptive but natural.
5. Add Title and Caption (When Needed)
- Title Attribute: Optional. Shows as tooltip text when hovering.
- Captions: Good for UX but not mandatory for SEO.
6. Use Correct Image Dimensions
- There is no need to upload an image that is sized 3000 px in width when it will be displayed at 600px.
- Shrink forthcoming images.
This saves space and improves load speed.
7. Use Lazy Loading
The phenomenon known as lazy loading implies that images are loaded whenever they enter the user viewport.
- Faster initial page load.
- Saves bandwidth.
→ Modern HTML now supports this easily:
<img src="example.jpg" loading="lazy" alt="Example image">
