We must become familiar with its main ideas and tenets in order to comprehend image SEO.
Use of relevant, high-quality photographs is the initial step in the image selection process. Using inappropriate or subpar photos can hurt your SEO efforts. To prevent legal problems, make sure you have permission to use the photographs. Use original photos instead than stock ones whenever possible.
File Format: JPEG, PNG, and WebP are the three most popular picture file formats. For pictures, JPEG is favored since it offers good quality with a smaller file size. PNG is the best format for images with transparent backgrounds, such as logos. In comparison to JPEG and PNG, the Google-created WebP format offers better quality and compression ratios, and it is increasingly supported.
Picture Size and Compression
Slow website load times, a key ranking issue for search engines, can be caused by large picture files. It’s crucial to compress your photographs in order to reduce file size without sacrificing quality. Online resources abound for this purpose.
Search engines employ image file names to decipher the content of the images. Rename the file to include your desired keyword or phrase rather than a generic name like “IMG_12345.jpg”.
Search engines and people with visual impairments can better understand images when they have alt text, often known as “alternative text” or “alt text.” Alt text must accurately reflect the content of the image and contain pertinent keywords; keyword stuffing must be avoided.
Title Text
Also referred to as “title tags,” title text offers more details about an image and is typically shown when a user hovers over one. Although it doesn’t directly affect SEO, it can enhance user experience.
While captions are not always necessary, they can assist readers better grasp the context of an image. According to Google, captions are useful for image SEO.
Structured Data
Using particular types of markup on your website gives search engines a better understanding of the content. Your photographs may then show up in rich results as a result.
Sitemaps for Images
Including image metadata in your sitemap will aid Google in finding your images if your website makes use of JavaScript galleries or image pop-ups.
Photographs That are Responsive
As more people use mobile devices, you must make sure that your photographs look excellent on all of them. HTML5 has elements and properties that can deliver the correct picture sizes to various devices.
The foundation of Image SEO is knowledge of these ideas, but it is not a “set it and forget it” activity.

How to use Image SEO Correctly
Let’s grasp the significance of each of the aforementioned concepts and how they affect SEO as we go deeper into image SEO.
1. Image Selection
Since Google’s algorithm can understand the text within photographs, selecting pertinent images can have a big impact on how search engines see your website. Images that aren’t relevant could fool both users and search engines. Additionally, using visually appealing, high-quality photos on your website can lower bounce rates and boost user engagement, both of which indirectly raise your SEO rating.
2. File Format
Each type of image format has its own set of benefits. JPEG images can be compressed further without sacrificing quality, and as a result, they load more quickly, improving user experience. PNGs are excellent for diagrams and logos since they offer transparency. The best of both worlds is offered by WebP, however certain older browsers may not be able to use it.
3. Image Size and Compression

4. File Name
By providing a meaningful file name for your image, you aid search engines in comprehending the information of the image. Because search engines can’t “see” photos the way people can, this is particularly crucial. A precise, keyword-rich file name can give context and raise the relevance of your image in user searches.
5. Alt text
Google reads alt text to comprehend the content of images. Alt text gives a description of the image for screen reader users who have visual impairments. The total keyword density and relevance of your website can be improved by properly optimizing the alt text.

8. Structured Data
By using structured data, you may improve how Google understands your website and its content, enabling enhanced and unique search result features. Structured data, for instance, can assist Google in comprehending that a specific image is your trademark or is associated with a specific product or dish.
9. Image Sitemaps
By giving Google more details about the photos on your website, image sitemaps help Google find your images more easily. This is especially useful for websites that display photos using JavaScript.
10. Photographs That are Responsive
In light of the rise in mobile surfing, it’s crucial to make sure that your photographs are correctly viewed on all devices. You can guarantee that the user has the best possible experience on any device by employing responsive pictures.
This analysis shows that there are many aspects involved in image SEO, and each one contributes to improving your site’s visibility and user experience.

Images are only loaded using the lazy loading technique when they enter the viewport. This is especially useful for pages with loads of photos because it speeds up the first page load, which enhances user experience overall and site performance—both crucial SEO criteria.
2. Use of CDNs
To reduce latency and increase image load times, Content Delivery Networks (CDNs) distribute your content over a number of different locations. Improved user experience and improved SEO are two benefits of faster load times.
3. Utilizing Browser Caching
By enabling browser caching, you can reduce the load time for repeat users to your site because the images are already cached. Better user experience as a result of a faster load time will ultimately benefit your SEO efforts.
4. Prioritize Above-the-Fold Content
If your photos are above the fold, which is the portion of a page that can be viewed without scrolling, make sure they are optimized first since this is what a visitor will see first. The user experience and SEO are enhanced as a result of the perceived load time reduction.
5. Implementing Next-Gen Formats
Because they offer better quality and compression than earlier formats like JPEG or PNG, consider utilizing next-generation formats like WebP, JPEG 2000, or JPEG XR.
6. Combining Images into a CSS Sprite
If your website has numerous little images (such as icons), you can combine them into a single image (a sprite), and then use CSS to display only the area you require. As a result, load times are improved by lowering the amount of server queries.
7. Utilizing 3D Images and Augmented Reality
As technology develops, so do the engagement possibilities. Brands are now able to offer distinctive and interactive experiences thanks to the growth of augmented reality (AR) and 3D imagery. Although these technologies might not directly boost your SEO, they can greatly enhance engagement and time spent on the site, which will help your SEO in the long run.
8. Decorative Images
The alt attribute for decorative images that don’t contribute to the content should be left empty (alt=””). By enabling screen readers to ignore the visual, accessibility and user experience are enhanced.
9. Avoid Using Links
Avoid using links to your photographs, if at all feasible. Both the image and the link will be lost if an image link is broken. If you must utilize picture links, be careful to include a meaningful alt text.
