Why Optimizing Images for SEO in WordPress Matters
Human vision is different from how search engines work. Search engines can’t “check” images like we do. They identify images by using file names, alt text, and image size details.
- Image optimization should be your top priority. It offers these key benefits:
- Your site becomes faster because smaller, optimized images reduce the page-loading time.
- Users like fast-loading websites, so Google gives those sites higher rankings.
- Speedy and organized web pages cause users to stay on the site longer.
- Image search boosts traffic. Labeled images show up on Google Images, bringing more visitors to your website.
Ready to get started? Let’s break it down!
Step 1: Choose the Right Image Format
Many image formats exist for different image tasks. Choosing the right platform starts the optimization process.
- JPEG: Great for photos or detailed images. Quality remains high when you achieve a reduced file size.
- PNG: Perfect for images with transparency or sharper details. But larger file sizes.
- WebP: A modern format with smaller sizes and high quality. It’s ideal for WordPress!
- SVG: Best for icons or logos. Scalable and lightweight.
TinyPNG and Squoosh remain excellent options for image compression that preserve picture quality.
Step 2: Resize Your Images
Larger image file sizes slow down website loading speed. Resize your images before uploading. This will help to load image fast in your web page.
For example:
- Blog Post Images: 1,200 x 628 pixels
- Thumbnails: 150 x 150 pixels
- Full-Width Backgrounds: 1,920 x 1,080 pixels
Most WordPress theme have a default image resizing feature. Choose file sizes that fit your needs before uploading new images to your site.
Step 3: Compress Your Images
The compression method enables users to decrease file dimensions without generating visual degradation.
Use WordPress plugins like:
WordPress quickly shrinks the file sizes of your uploaded images.
Step 4: Use Descriptive File Names
Google utilizes the file names of images to understand what they depict. Use descriptive keywords instead of naming them IMG123.jpg.
Example:
- Bad: IMG001.jpg
- Good: optimizing-images-for-seo-in-WordPress.jpg
Hyphens should divide words rather than using underscores.
Step 5: Add SEO-friendly alt text.
Images need alternative text to explain their content. This helps search engines know what they show. Screen readers and search engines use this text to understand images.
Example alt text:
“Woman optimizing images for SEO in WordPress on a laptop.”
Show the image clearly with a simple description. Include relevant keywords.
Step 6: Use Lazy Loading
Images load as the viewing area shows them in lazy loading. This method speeds up initial page loading times.
The best part? Lazy loading is in WordPress 5.5 and later. You can access more features using the Lazy Load plugin from WP Rocket.
Step 7: Create an Image Sitemap
An image sitemap makes your images detectable and indexable by search engines.
The Yoast SEO plugin and Rank Math let you automatically submit images to your sitemap. Using image sitemaps can boost your ranking in Google Images.
Step 8: Leverage a Content Delivery Network (CDN)
Content delivery networks let you store image copies on servers around the world. The nearest server sends images to your users. This lowers loading times.
Top CDNs for WordPress:
- Cloudflare
- BunnyCDN
- StackPath
Step 9: Test and check your results.
Check your website speed after you optimize images. You can use Google PageSpeed Insights, GTmetrix, or Pingdom Tools.
