Good Website Tip 139 ★ Follow these 7 steps to boost your image SEO ★
Images can make your website look great, but they can also slow it down or hurt your SEO if used incorrectly. A few simple steps can make a big difference.
1) Use descriptive filenames – Rename your image files with specific, keyword-rich names. Instead of “IMG_1234.jpg,” use something like “red-running-shoes-nike.jpg”.
2) Write accurate ALT text – Each image should have clear ALT text. Describe what’s in the image and its purpose, including relevant keywords naturally.
3) Pick the correct format – Use JPEGs for photos, PNGs for images with transparency and graphics, and WebP or AVIF for smaller file sizes without losing quality.
4) Compress your images – Keep file sizes small (under 100KB if you can). This speeds up your website and helps with SEO rankings.
5) Resize images to fit the display – Don’t upload large images and rely on CSS to shrink them. Resize images to the actual size they will appear on the page.
6) Add width and height attributes to your HTML – This prevents layout shifts and improves your Core Web Vitals. Always include width and height attributes in the image tag.
7) Use lazy loading – To speed up loading, set images that aren’t visible on the screen to load only when the user scrolls to them.
Each one of these steps helps your SEO and makes your site faster and more user-friendly.
