In SEO, nothing should be left to chance. If you want to increase visitor traffic and improve the effectiveness of your calls to action, it is in your best interest to improve the visual elements that are an important attraction factor, as well as the code, text and other content.
The importance of images for websites
The person responsible for creating websites knows that he or she must focus on both an easy-to-navigate infrastructure and valuable content in order to attract users' interest for calls to action.
Think for a moment about how many searches you do on Google Images every day (for example, when you're looking for visual inspiration or when you want to get a feel for the features of a certain product) and you'll get an idea of how many visits good, attractive images are able to attract to your site.
Photos also have the merit of breaking down the cluttered walls of text that discourage you from reading and draw you to important content.
For this reason, it is always a good idea to introduce visual content such as:
an image that illustrates the meaning of the concepts being presented (if you're talking about a computer procedure, for example, you might insert screenshots of code to help you design the procedure)
a video related to the topic (an illustrated procedure helps understanding and makes the accompanying articles more relevant)
an infographic that allows you to understand a lot of data in a small space and share it easily

How to optimize images on the SEO side for websites?
High-quality images are the ones that undoubtedly help capture attention on the page, but a good resolution also means more weight, and this inevitably affects the time it takes to show visitors the entire page. Fortunately, there are a number of tools at your disposal to reduce the weight of intuitive image use that help you achieve a good balance between visual quality of photos and their heaviness in terms of size.
It's also about looking at images from a size perspective: if you just load the illustrations with their original proportions, you'll force browsers to waste precious seconds resizing them to fit the devices visiting the page.
If you recognize, as I've mentioned in several articles, that the vast majority of visits are through tablets and smartphones, you'll have an idea of how neglecting image size can hurt your website user experience.
With free online tools such as TinyPng, you can easily adjust the size of images to a more suitable size for your pages.
This way, you make it easier for browsers to save you unnecessary efforts and render pages to visitors faster.
Aspects of image files are equally important for search engine optimization of images.
Optimization of associated tags
The tags associated with their definition can be optimized according to criteria of meaning for search engine crawlers, which can then take in more information about the visual content they are analyzing.
The tags to take into account are
the file name: renaming an image before uploading it to the site is a good way to increase the relevance of visual content compared to text
the title: a reminder of the content of the photo that allows you to display a text overlay when you move the mouse over it
the ALT tag: an indication of the meaning of the image which can be useful for blind people who consult the website with special browsers
the description: in this field you can enter a brief description. This should not be a true representation of the content of the image, but rather a conversion aid for the user. Of course, these fields should not be filled in as a photocopy of either, but should be used to provide different forms of meaning to the reader. The file name can provide an indication of what the photo is about, the description highlights the message of the page, the Title tag provides a specification of what the image wants to communicate, and the ALT tag specifies the content of the image for the human reader.
