Best WordPress Image SEO Practices That Actually Work

While optimizing WordPress for SEO, many focus on keyword placement, internal linking, human-written content, and backlinks. However, one critical element of on-page SEO is mostly overlooked, which is image optimization. Images are mainly used to make the pages visually appealing. This is important, but what if search engines do not understand your images? It would be a downfall for your page if your images are not SEO optimized to enhance the ranking.

Proper image SEO improves your site’s speed and boosts your rankings on Google, including Google Image Search. Now, let’s discuss some WordPress image SEO practices to make this happen.

Why Optimize Images for SEO in WordPress?

Images make your content appealing and engaging, so using them is a plus point for your blog post or product pages. However, if not optimized, images can delay your website’s loading. Google prioritizes websites that load quickly, so image optimization is a key part of that.

Optimized images also help Google understand what your images are about because it technically cannot see the image like we do. This understanding improves your appearance in search results. Plus, images can bring additional traffic through Google Image Search.

In summary, SEO for WordPress images helps you:

• Speed up your website
• Improve accessibility for visually-impaired users
• Increase organic traffic through image search
• Enhance SEO rankings

Best SEO Practices for Images on WordPress

Optimizing images is easy; you just have to remember a few techniques while doing SEO, and your blogs and pages are good to go with images.

1. Name Your Image File Properly

When you download or design an image on your PC to upload to your WordPress site, your SEO starts exactly there when you name that file. This may seem irrelevant, but it is important. Let’s say you are writing an article on “On-page SEO for WordPress”, and the image you upload has the file name “Image01.JPG”. This file name is very generic and practically useless. Instead, name the file with your focus keyword, so Google can understand your image without analyzing it.

2. Never Forget ALT Text

Alt text (alternative text) is the phrase that explains the content of your image. Your Alt text should have the potential to describe the image so it can be understood without looking at it. This will be helpful for visually-impaired users and help search engines understand them, as they can’t see your images. Always use your focus keyphrase in ALT text to create relevance of the image with your topic. Also, don’t confuse your Alt text with captions, which provide additional information about the images.

3. Choose the Right Image Format

There is no such thing as a right format for images, as there are many, and each serves a different purpose. So, choose the format based on the purpose of the image you are uploading.

• JPEG is ideal for photographs and illustrations.
• PNG is better for photos with transparency or sharp lines.
• Consider WebP, a modern format that does excellent compression without pixelating images.
• For icons, SVG is a preferred format.

4. Compress Images to Reduce File Size

Image size matters, as large images need more time to load. Try to compress your images to the smallest size possible (< 100 KB), where the quality still stands. You can use compression tools or WordPress plugins like Smush or ShortPixel. These help in size reduction without pixelating the image.

5. Use Responsive Images

This is an important SEO thing. WordPress automatically generates multiple image sizes and serves the appropriate one depending on the user’s device. Make sure your theme supports responsive images so your image looks perfect, especially on mobile devices.

6. Add Captions When Relevant

Like Alt text, captions are also important as they provide additional context to users so they can easily comprehend the image. Use them sparingly and try to write captions that add meaning to your images and blog posts rather than clutter.

7. Implement Lazy Loading

Lazy loading is important for improving a site’s performance. It delays the image loading until it appears in the user’s viewport. This speeds up the loading time of your site. However, since WordPress 5.5, lazy loading is built in by default.

8. Create Image Sitemaps

Submitting an image sitemap to Google Search Console helps Google find and index your images faster. The site map could be a part of your overall site map or can be added separately for images. You can manually create an XML file for this or use WordPress plugins like  Yoast SEO and Rank Math to get that automatically.
