Image Optimization Basics - How to Create SEO-Friendly Images That Improve Website Performance

Images can strengthen your content, but only when they are optimized correctly.

Use relevant images throughout your content

Visuals should support the written content, not distract from it.

• Choose images that directly relate to the topic
• Place images close to the text they explain
• Whenever possible, use original photos instead of stock images

Rename image files before uploading

Search engines read file names, so generic names hurt SEO.

• Rename files before uploading
• Use 2 to 4 descriptive words separated by hyphens
• Add a keyword only if it naturally fits

Example:

• Poor: IMG_7852.jpg
• Better: big-brown-bag.jpg

Keep file names clear and concise.

Reduce file size and choose the right format

Oversized images slow down your website.

• Use JPG or JPEG for most photos
• Keep image files under 1 MB when possible
• Resize images before uploading, not after

Faster pages improve rankings and user experience.

Write clear alt text

Alt text helps screen readers and search engines understand images.

• Describe what the image shows
• Use keywords only when relevant
• Avoid repeating the same alt text across multiple images

Example variations:

• Mixing chocolate chip cookie dough
• Fresh baked cookies cooling on a rack

Add captions when useful

Captions can increase engagement and clarity.

• Explain what the image represents
• Keep captions short, 1 to 2 sentences
• Include keywords naturally

Only use captions when they add value.

Video Optimization Tips

Videos increase time on page, but they need optimization to perform well in search.

Design strong thumbnails

Thumbnails influence whether users click.

• Match the thumbnail to the video content
• Use clear, high-quality visuals
• Avoid misleading imagery

Use descriptive video names and titles

Rename video files before uploading just like images.

• Use descriptive wording
• Avoid default camera file names

Avoid video duplication across pages

Embedding the same video on multiple pages can dilute SEO.

• Assign one primary page per video
• Link to that page instead of re-embedding
• If needed, use canonical tags via an SEO plugin
• Add captions or transcripts

Transcripts improve both accessibility and search visibility.

• Search engines can index the text
• Users with hearing impairments benefit
• Content becomes eligible for more search queries

How to do it:

• Write or generate a transcript
• Add it below the video
• Clearly label it as “Video Transcript”

Final Media Optimization Checklist

Before publishing, review your content:

• Image file names are descriptive
• Alt text is present and unique
• Large images are compressed
• Captions are added where helpful
• Videos have thumbnails and transcripts

Optimizing your media improves SEO, usability, and accessibility, creating a better experience for every visitor.
