Image optimization

Are your images lightweight, described, and helping your SEO?

📖 Detailed description

Images are not just decoration - they can attract traffic from Google Images and have a significant impact on your page speed. Heavy, unoptimized photos are like hauling bricks in your trunk - you are slowing yourself down for no reason!

Google does not "see" images the way we do - it needs descriptions to know what they show. Alternative text (alt) is like describing a photo over the phone to a blind person - it should be accurate and helpful.

File size matters too. A photo from your phone can be 5MB - but on a web page, 100KB is enough for it to look identical! That is the difference between loading in 1 second and loading in 10 seconds on a slower connection.

Most common problems

Files too large

The page loads slowly, especially on a phone

No alt text

Google does not know what is in the image

Bad file names

IMG_1234.jpg says nothing about the content

Wrong format

PNG for photos = enormous files

How to fix it?

Compress your images - aim for under 200KB

Use WebP or JPEG for photos, PNG for graphics with text

Add descriptive alt text to every image

Name files descriptively: pizza-margherita.jpg, not IMG123.jpg

Use lazy loading - images load only when they are needed

Examples

Good example

Bad example

<img src="DSC0001.JPG"> (5MB, no alt)
