What is Image Optimization?

When you add images to your blog, they take up space and can slow down your website. Image optimization helps you compress images, reduce file size, and convert to formats like WebP or AVIF without sacrificing quality. The goal is to make your website faster while keeping images sharp.

You can optimize images by resizing, compressing, or converting them to next-gen formats like WebP and AVIF. Lossy compression reduces file size more aggressively, while lossless compression keeps every detail of the original image.

A good image optimizer can help you automatically compress your images while keeping them looking great.

Why is Image Optimization Essential for Bloggers?

When images are too large, they slow down your website’s load time. A slow website hurts user experience and can lower your SEO rankings. Faster-loading images improve your website’s speed, making pages load faster and keeping visitors engaged.

If you use WordPress, an image optimization plugin like EWWW Image Optimizer can help you compress images in bulk and optimize existing images in your media library.

With a WordPress plugin, you can automatically compress your images upon upload and convert images to WebP or AVIF for a faster website.

A faster website improves PageSpeed scores and reduces bandwidth usage, which is especially helpful if your hosting plan has limits. With an image optimizer plugin, your website loads faster without sacrificing quality.A well-optimized blog doesn’t just load faster; it also improves PageSpeed scores, reduces bandwidth usage, and enhances mobile performance.

This ensures that every image is optimized for faster loading times without compromising appearance.Support for Multiple Image FormatsYour image optimizer should work with standard formats like JPEG, PNG, JPG, and GIF, as well as newer formats like WebP and AVIF. WebP images load faster than JPEG and PNG, and AVIF files are even smaller without sacrificing quality.Some tools also support HEIC, which is used on Apple devices and can convert images to WebP for better performance across all browsers. Make sure the software you choose allows WebP conversion and supports multiple formats.Bulk Optimization CapabilitiesIf you already have a lot of unoptimized images on your blog, you need a tool that can compress images in bulk.

How to Use SEMRush for Image Optimization

Source: Canva ProStep 1: Run a Site Audit to Find Image IssuesFirst, log in to your SEMRush account and run a Site Audit. This tool scans your website for SEO issues, including image-related ones. It’ll highlight:

Large image file sizes are slowing down your site

Missing alt text (important for accessibility and SEO)

Broken images that need fixing

To run the audit, go to Site Audit under the SEO Toolkit, enter your website URL, and let SEMRush do it.Step 2: Compress and Resize ImagesOne of the most significant issues with SEMRush flags is the large image sizes. If your images are too big, your site will load slowly, which hurts SEO and user experience. SEMRush recommends reducing file sizes without losing quality.

Use tools like TinyPNG, ShortPixel, or Photoshop to compress images before uploading them.Step 3: Add Alt Text and Descriptive FilenamesSEMRush also points out images missing alt text, a short description of the image that helps search engines understand what it’s about. This is super important for SEO and accessibility.

Instead of naming an image IMG1234.jpg, rename it chocolate-cake-recipe.jpg (if it’s a picture of a chocolate cake, of course).

Add alt text like: “A homemade chocolate cake topped with fresh strawberries.”

You can check for missing alt text in the On-Page SEO Checker or your Site Audit report.Step 4: Use the Right Image FormatSEMRush might suggest switching image formats to improve loading speed. Here’s a quick guide:

JPEG – Best for photos with lots of colors

PNG – Best for transparent backgrounds

WebP – Best for fast-loading, great-quality images (Google loves this format!)

Consider converting your images to WebP using tools like Squoosh or CloudConvert if your pictures are in older formats.Step 5: Implement Lazy LoadingLazy loading is a technique that loads images only when they appear on a user’s screen. This makes your pages load much faster. SEMRush may recommend enabling lazy loading if your images are slowing things down.If you’re using WordPress, plugins like WP Rocket or Lazy Load by WP Rocket can easily handle this.Step 6: Monitor and Improve RegularlySEO isn’t a one-time thing. Regularly check SEMRush’s Site Audit to catch and fix new image-related issues.Wrapping UpChoosing the right image optimization software for your blog can make all the difference in site speed, SEO performance, and user experience. While there are many options, SEMRush is the best choice, offering powerful features beyond simple compression. With its advanced SEO insights, seamless integration, and top-tier optimization tools, you get a complete package to enhance your blog’s visuals without compromising performance.Want to stay updated on the best deals?
