A simple image SEO checklist covering filenames, alt text, dimensions, compression and internal links.
Rename files clearly
Use descriptive filenames such as compress-image-online.webp instead of IMG_4827.jpg. This helps organization and search context.
Write useful alt text
Alt text should describe the image naturally. Avoid keyword stuffing and write for people first.
Compress every large image
Large files slow down pages. Compress photos and thumbnails before publishing them.
Set width and height
Adding image dimensions helps the browser reserve space and reduces layout shift.
Use internal links
Link your blog guides to useful tools such as the Image Compressor, Resizer and Converter. This improves navigation and keeps users on your site longer.
