Image SEO Optimizer: Automatic optimization for WordPress

May 6, 2020 | Marketing, WordPress | 0 comments

If you have already created a website with or without WordPress, you know that search engine optimization is an important task to ensure that your website is found by people. One of the most important on-page SEO optimizations is to describe the file path, file name and alt text of your images in a descriptive way, because search engines like Google don’t understand the content of your images automatically – or won’t understand them, because it is too expensive to do it for all the images on the web. For many modern websites, images are one of the key elements of their content, and if the amount of images is huge, it can be difficult to SEO-optimize every single image. This is exactly where the WordPress plugin Image SEO Optimizer promises to help.

What does Image SEO Optimizer do for your image search engine optimization?

Image SEO Optimizer has developed an artificial intelligence (AI) system that grabs the image you have uploaded into your WordPress. The AI tries to understand what the image shows and searches for similar images on the web that rank well in search engines. From these images it knows for which keywords your image could be rank high in search engines and automatically generates an SEO-optimized alt text with up to two keywords and a file name that matches the content of the image.

The automatic generation of the alt description and the file name can save you a lot of time. Only one thing the plugin does not do for you in terms of search engine optimization of images: A descriptive file path – the part before the file name – is not optimized. But don’t worry, here the plugin Real Physical Media, which reflects the folder structure of your organized WordPress media library created with Real Media Library, can help.

Practical test: How does Image SEO Optimizer work?

You can start with Image SEO Optimizer quite easy and for free, but as you might expect, and AI is not a simple system that costs a lot of development effort, Image SEO Optimizer is not free if you want to optimize your whole media library. Have a look at the prices on their website.

  1. Download the plugin Image SEO Optimizer from wordpress.org and install it under Plugins > Add New in your WordPress backend.
  2. Go to the new menu item ImageSEO in the left sidebar. Here you have to get an API key from the service to access its AI resources.
  3. After that you can go to ImageSEO > Alt Optimizer. On this page you can define how the AI should generate the alt texts and the file name and start optimizing your images.

It’s pretty easy to get started with this plugin, which can save you time in the daily SEO optimization of your website, especially the images on your website.

Results: AI is good, a human is better

The most interesting thing about a WordPress plugin that promises to solve any problem with artificial intelligence that a human normally has to do is how good the results are. We have tested Image SEO Optimizer with 100 images. 50 of them were stock images from platforms like Pixabay and the other half were images from my private images that have not yet been published on the internet.

Overall, Image SEO Optimizer renamed all images and generated alt texts for all images, and about 60% of them were meaningful. By meaningful we mean that it really describes the content of the images. Sometimes even exactly like the picture of a MacBook Pro, where the AI determines the exact model and year. That was impressive!

When you look at the two groups, you see a clear difference in the results. While only about 40% of my private picture was described there with a meaningful wording, about 80% of the archive pictures had a good description. I think the reason for this behavior is easy to explain: Most of the stock images on the internet have already been used in several websites, and they have already created meaningful alt texts as well as file names for it. The AI could use this data to create a meaningful summary of it. If the AI does not have this additional information, it only has to work with its image recognition data, which is not always correct in any AI system.
It is now worth using Image SEO Optimizer if it does not always give you the right result? I would say it depends on your use case. A name and alt text is always better than none, because not having one clearly signals to Google and Co that you don’t care about search engine optimization. If you would not add them by hand, e.g. because you have a huge amount of images on your website, I think Image SEO Optimizer is the solution for you, because it solves this problem quickly and with a noticeable SEO boost for you. If you optimized SEO image content by hand anyway and spend a lot of time on it, you should rather do it by hand, because you will get the better results here. Quite simply because in tasks like this, a human is still better than any artificial intelligence.
