When browsing websites, visual content undoubtedly captures attention first, and it's often what determines whether we stay on a page. Yet, technical audits of websites frequently reveal that image optimization is neglected. Among many settings, images are only partially or not at all addressed. Their importance should not be underestimated, especially for sites that rely on visual appeal or sell products.

Why should you focus on image SEO?
Have you ever searched for a product based solely on images? Image optimization is particularly crucial in industries where users frequently search by images – for example, clothing, decor, or other products.
This also holds true for text-based searches: if you type in a search term, images will certainly appear among the results, and due to their eye-catching nature, they can generate clicks even if they are located further down, below the text results.
Images need to be optimized so they can appear as frequently as possible in relevant search results. With the right settings, search engines can better understand the content of images and display them to users in the appropriate places.
What factors should we consider?
Choosing an Image Format
Choosing the right image format is crucial for website efficiency and speed. For optimal performance, the WebP format is recommended as it allows for faster page loading.
- PNG: This format supports transparency and compression, but it's not recommended for SEO due to potentially larger file sizes, which can slow down page loading.
- JPG: This format uses lossy compression, which allows for relatively small file sizes while maintaining adequate image quality.
- WEBP: This format is highly recommended for SEO, as it provides excellent image quality, supports transparency, and also handles animations.
- SVG: This format is vector-based, meaning images can be scaled to different sizes without loss of quality. SVG files are text-based, which helps search engines understand and index them more easily.
Image Quality and Compression
Most websites make a serious SEO mistake by simply uploading images without checking their size. Nobody likes waiting minutes for a webpage to load. If there's a long wait, users will click away, meaning hard-won search rankings won't bring visitors, or expensive advertisements will be wasted. Reducing image size is fundamental because smaller images load faster, which improves the user experience.
While it can be time-consuming, reducing image size is an important part of the optimization process. Image compression reduces file size without significantly degrading image quality. This is especially crucial for fast page loading and a better user experience (UX) . There are many online tools, such as TinyPNG and ImageOptim, that allow you to easily compress images.
Don't forget about image names and ALT attributes!
Many people confuse these two concepts. Let's briefly clarify what each tag is for.
Image names are the actual names of image files, which are short, contain relevant keywords, and are separated by hyphens. For example: "red-rose.jpg". Search engines use filenames to understand and index image content, but this is less emphasized than the ALT attribute.
ALT attributes are part of the HTML code that describe the content of images. They briefly and accurately describe the content of images and can also contain important keywords. For example: <img src="piros-rozsa.jpg" alt="Red rose in the garden">.
ALT attributes help search engines understand image content. Search engines use these attributes to index images more accurately, and their role in SEO is also greater. Additionally, ALT attributes help visually impaired users who use screen readers to understand website content.
#m1-y#Using both is beneficial for search engine optimization and user experience, but it's important that at least the ALT attribute is filled in!##
Use responsive images!
Today, users most often browse websites on smartphones.
When you view a page on a smartphone, images automatically load in a smaller size, making the page load faster. When you open the page on a desktop computer, the same image appears in a higher resolution.
Responsive images ensure that images display correctly on all devices and screen sizes. This also improves user experience and page loading speed.
Create a separate sitemap for images!
Creating an image sitemap is an excellent way for search engines to more easily find and index your website's visual content. Such a sitemap helps search engines understand where images are located on the website and how important they are for the content. This file can be submitted to Google Search Consoleto help search engines index images.
Useful techniques for faster loading times
In addition to optimizing images, other techniques can be used for faster loading times, such as lazy loading.
Lazy loading means that images only load when the user actually scrolls to them on the page. This significantly reduces the initial page load time, as not all images need to be loaded at once.
The cache is also an effective technique that allows websites to load faster. Its essence is to store frequently used data on the user's device. When a visitor first opens a website, the browser downloads and stores images, stylesheets, and other resources in the cache. Thus, when the user next visits the same page, the browser loads these resources from the local cache, which significantly reduces page load time.
#m1-p#Caching not only provides a faster user experience but also reduces server load, as less data needs to be downloaded repeatedly.##
Does it matter where the uploaded image comes from?
Yes! Uniqueness is definitely an advantage: when you use your own created or uniquely edited images that don't appear anywhere else, Google's algorithms prioritize them. Stock photos can appear on multiple websites, making them less valuable from an SEO perspective than custom-made images.
It's also worth the effort to use your own images because they convey uniqueness and professionalism, thereby strengthening your brand's credibility and expert status. Using them helps your brand stick in visitors' minds. Furthermore, all custom-made images are copyright-free, so you don't have to worry about legal consequences.
How can we tell if our images are properly optimized?
To check this, we primarily recommend the following two tools:
Google PageSpeed Insights
The Google PageSpeed Insights analyzes website performance, including image optimization. It provides suggestions for reducing image size and using appropriate formats.
Google Search Console
In the Google Search Console, we can track how images perform in search results. Using it, we can check which images generate traffic and where they appear in search results. This data can help fine-tune image optimization.

If, even after using the tools above, you're still not sure if your images are optimized correctly, an expert-conducted SEO agency audit can be very helpful.
