10 Techniques For Image SEO Optimization

If you are familiar with the foundations of image SEO optimization, your material will have the best chance of succeeding with SEO.

Images are essential for SEO as well as boosting your content’s usability, appeal, and user engagement.

What does image optimization entail?

Images must be created and distributed in the finest format, size, and resolution available to increase user engagement. It also requires correctly identifying them with metadata so that search engine crawlers can read images and understand page context.

According to HTTP Archive, in 2018 images made up 21% of the weight of a typical web page, taking up more bytes than any other element of the website. This proportion is probably higher now that more people are using pictures. As a result, image complexity and size have a considerable impact on site speed.

When you can reduce the size of images without compromising quality, both the user experience and website load times improve. Search engine rankings may be improved as a result, which would boost customer engagement, conversion, and retention rates.

TIP: Optimized images take up less space on the server, and site backups are completed more quickly.

Techniques :

1. Image scaling

The file size and the image size are not the same. Image size refers to the dimensions of an image (e.g., 1024 pixels by 680 pixels). Storage space is determined by file size (e.g., 350 kilobytes).

TIP: Refer to this article to discover the best image sizes for social media platforms.

Save appropriate format

PNG, JPEG, and GIF all have advantages. I suggest selecting JPEG for images with a lot of colour and PNG for simple ones.

Choosing the right compression ratio

Experiment with different compression rates and file types to see which works best for each image. Several image editing tools, notably Adobe Photoshop, provide a save-for-the-web feature that automatically shrinks the file size while preserving image quality.

These applications and plug-ins are helpful even if you don’t use Photoshop:

Test speed

How do you tell if, after optimising your photos, the page load times for your website are swift enough? Use one of these tools to measure your website’s speed:

TIP: Pay attention to load times if the content on your website changes frequently.

2. The names of the images should be improved

Give the file a name that incorporates relevant, in-depth keywords to optimise SEO potential. Put the target keywords at the beginning and separate them with hyphens. Avoid using underscores since they make it difficult for search engines to recognise individual words.

The file names ought to be comprehensible to both people and search engines. If the original name for an image of a woman at a hair salon is salon234.jpg, rename the image with a descriptive name, such as woman-having-a-haircut-in-a-salon.jpg.

3. Use alt tags

Search engine spiders needs suggestions even though visitors might understand the visual. Without replacement text, search engines cannot properly index your image content.

A decent alt tag gives context and benefits users who are blind as well. Additionally, the alternative text can be read by search engines to determine the page’s ranking when a bug stops an image from loading. In the alt tag, include more information than the file name. To say something about the image, aim for 10 to 15. People who are blind benefit from the context provided by an appropriate alt tag. When a problem prevents an image from loading, it is very helpful that search engines can understand the alternative text to determine how to rank the website. More information than just the file name should be in the alt tag. For a good description of the visual, aim for 10 to 15 words.

TIP: Brand-relevant terms should be used in the alt tags to boost visibility, but refrain from stuffing the tags with keywords.

4. Image creation for mobile devices

Because Google’s algorithm uses mobile-first indexing, crawlers typically look at a site’s mobile version. Your photos should therefore be suitable for mobile devices. How? The quickest solution is to make sure that your website’s graphics and design are responsive to mobile devices.

You can adjust an image’s size based on the width of a device even though some website builders and layouts automatically scale photographs. To do this, add some unique CSS code to your website. See this quick guide for more details on how to make your photographs responsive.

5. Improve the image’s title

The title of an image in WordPress is normally determined by the file name. If you don’t use WordPress or the title doesn’t adequately describe the image, you should update it to include the necessary keywords in the same way as file names.

Image names can assist the alt text by providing more context, even though they are less important for SEO. To encourage user involvement, think about adding a succinct call to action like “buy now” or “download today” in the image title.

6. Include captions

SEO could not be directly impacted by image captions or the text that appears beneath images. In contrast to file names and alt text, captions are visible and can improve the website experience. With the addition of captions, SEO can be indirectly improved while improving user experience and engagement metrics.

7. Use original images

It’s acceptable to use stock photographs, but since many other websites presumably do the same thing, they probably won’t help your website’s search rankings. Uploading original photos makes sense, much like original text is better for SEO.

8. Verify that the text and the images are in sync.

Increase the description of an image if your wording doesn’t explain it well enough so that search engines can understand its relevance.

9. Incorporate structured image data

Use Google’s general guidelines for structured data to learn how to add structured data to your pages while adhering to search engine requirements.

10. Use site maps

A site map is “a file where you can list the web pages of your site,” according to Google, and it helps Google and other search engines understand how your website’s content is organised. It is, in other words, a file that contains a list of the pages on your website.

Because they educate search engines about the pages and organizational structure of your website, site maps are an essential part of SEO. Infographics, memes, pictures, video thumbnails, and other forms of imagery should all be included in your site map to ensure that search engine crawlers can access them.

Include each image entry’s title, description, URL, caption, and licence information. For video entries, be sure to include the title, description, location URL, thumbnail URL, and URL to the raw video file.


So, what are you going to do now? The creation of high-quality content should be your major priority. Regardless of the subject, images are a crucial component of it. Please don’t hesitate to get in touch with the author, Rohan Babbar, if you have any inquiries.
