HOW to Optimize Images for WordPress?

We will describe some important key points for image SEO that are essential for optimized images:

Unique Images

Images should not be copied and pasted from Google or any other source. They must be unique. Google favors unique images, and we will ensure this for search engines. Try to use little images instead of large ones.

Name the Image

  • When saving unique images on your desktop, assign them relevant names.
  • Using keyword-rich names for images is highly beneficial for the user experience.
  • Images should be expressive and effectively convey the intended message, all while staying relevant to the topic.

Alt Text Best Practices

  • Alt tags or text are among image optimization’s most critical elements. 
  • They are essential for screen reading, as visually impaired individuals rely on screen readers. 
  • Alt text also aids search engines in understanding the content and displaying it on web pages.

It should be keyword-rich, expressive, and relevant. Adding text to the Title attribute is not as important as Alt text.

Alt tags are usually included within an image’s HTML code.

Attributes of an Image

Attributes of an image

 For example: <img src=“image-file.jpg” alt=“Alt text”>.

Image URL

The Image URL is essential for search engines.

  • It should include primary keywords and be relevant.
  • Optimizing Image Size significantly impacts image SEO and the overall optimization of the images.
  • Site speed depends on image loading.
  • When images are resized to a smaller file size (in kilobytes), it positively affects loading speed on the site.

What Are Our Requirements for Image Optimization?

Fast Loading

Fast loading is beneficial for page speed and good user experience.

Image Quality

Image quality attracts users, enhancing the overall user experience and engagement.

Now, if the size is good, downloading will be fast. Otherwise, it will be slow.

How to Manage Size and Quality?

We will strike a balance between the size and quality of images. It means we will compress our image size and slightly compromise quality. This compromise is referred to as a trade-off.

Why Do We Compress Images?

We want to compress images to reduce size because all data and content come from the server.

For example, suppose you search some queries on Google.

 How does data come to the computer? It is through data ➖ domain name system (DNS) ➖ IP address ➖ and from the server’s exact location, and we know all about data. We can boost our page speed with this process.


Image Optimization depends on the space where you intend to display the image. It’s not recommended to set a 1000×1000-pixel image if the required size is 500×500 pixels.

If ➖500 × 300 image size is two-dimensional.

1000×600 ➖double time width and length.

So, the dimension will be the actual size in kb➖quality is important.

Images Width for articles will always be 600, and length should vary accordingly.

It also depends on the website’s themes.

Compress and Resize Images in KB

We will compress images when reducing their size to ensure faster downloads. The image size should be in kilobytes (KB).

The best image size for SEO is 800×400

If an image is➖50mb in size and we need ten images for articles, it will affect our page speed. Just for that, we always compress images for better image SEO optimization. Compress images without losing quality.

Focus on Quality

We emphasize the importance of maintaining image quality.
