To Image optimization for SEO
Images are crucial for SEO as well as increasing the usability, appeal, and engagement of your content for consumers.
Your content has the best chance of succeeding with SEO, if you comprehend the fundamentals of image optimization.
How does image optimization work?
In order to improve user engagement, photos must be produced and delivered in the best possible format, size, and resolution. In order for search engine crawlers to read photos and grasp page context, it also entails appropriately identifying them with metadata.
The user experience and website load times both increase when you can minimise the size of photos without sacrificing quality. This may help increase search engine rankings, which in turn raises consumer engagement, conversions, and retention rates.
File size is not the same as image size. Image dimensions are referred to as image size (e.g., 1024 pixels by 680 pixels). File size is the amount of storage (e.g., 350 kilobytes).
Higher resolution and larger sized images will significantly slow down the loading of your page. They should be scaled down and sized for the web even though they are effective for printed products.
Save in the proper format.
Each of PNG, JPEG, and GIF has advantages. For photographs with a lot of colour, I advise using JPEG, and for straightforward images, PNG.
Select the appropriate compression ratio
Both file size and picture quality are influenced by how effectively an image is compressed; the smaller the file, the worse the image quality.
To determine which compression rate and file format is optimum for each image, experiment. A save-for-the-web option is available in several image editing programs, including Adobe Photoshop, that automatically reduces the file size while enhancing image quality.
These programs and plug-ins can be useful even if you don’t use Photoshop:
Tools for improving images
- Affinity Photo
- ImageOptim (Mac only)
- JPEG Mini
- Pixlr (JPEG optimization)
WordPress image-optimization plugins

2.Improve file names for images
To maximise SEO potential, give the file a name that contains pertinent, elaborative keywords. Include the target keywords at the start, and use hyphens to separate them. Avoid using underscores because they prevent search engines from “seeing” the words independently.
Both people and search engines should be able to understand the file names. Rename images with descriptive titles, such as lady-having-a-haircut-in-a-salon.jpg, if the original name for a picture of a woman at a hair salon is salon234.jpg.
3.Employ alt tags
While viewers could comprehend the visual, search engine spiders want hints. Search engines can’t correctly index your image content without replacement text.
An effective alt tag offers context and benefits people who are blind. The fact that search engines can read the alternative text to determine the page’s ranking is particularly beneficial when a bug stops an image from loading. The alt tag should provide more information than the file name. Aim for 10 to 15 to adequately describe the image.
4.Create mobile-friendly pictures
Crawlers primarily examine a site’s mobile version since Google’s algorithm utilises mobile-first indexing. As a result, your photographs ought to be compatible with mobile devices. How? The quickest response is to make sure your website’s pictures and layout are mobile-responsive.
Although some website builders and layouts automatically scale photos, you may customize an image’s size based on the width of a device. Add some custom CSS code to your website to do this. For more information on how to make your photos responsive, see this short guide.
5.Improve the picture’s title
WordPress typically uses the file name to determine the image’s title. To edit it with the required keywords in the same way as file names, if you don’t use WordPress or the title doesn’t describe the image, do so.
Although they are less significant for SEO, image names can help the alt text by adding more information. Consider using a quick call to action like “purchase now” or “download now” in the image title to increase user interaction.
Image captions, or the text immediately below photos, could not have an immediate influence on SEO. However, captions are visible and can enhance the website experience in contrast to file names and alt text. Enhancing user experience and engagement metrics can indirectly improve SEO with the addition of captions.
7.Use original photos
Using stock photographs is acceptable, but because many other websites probably do the same, they won’t necessarily improve your search rankings. Similar to how original textual material is better for SEO, it makes sense to post original photos.
8.Make sure the text matches the photos.
If your language doesn’t provide enough details to describe a picture, increase the description to help search engines identify the relevance of your photographs.
9.Include organised image data
Search engines will present your photographs as rich results when you include structured data on your pages. For product photos, videos, and recipe images, Google Images offers structured data. For instance, it adds a badge to an image if it recognises that it is accompanied with text, such as a recipe.
To learn how to add structured data to your sites while staying within search engine criteria, see Google’s general principles for structured data.
10.Make use of site maps
In order to inform Google and other search engines about how your site’s material is organised, Google defines a site map as “a file where you may list the web pages of your site.” In other words, it’s a file that includes a map of the material on your website.
Site maps are a crucial component of SEO since they inform search engines about the pages and organizational structure of your website. Include them in your sitemap to make sure that memes, pictures, video thumbnails, and other types of images are seen by search engine crawlers.
Include the title, description, URL, caption, and licensing details for each image entry. Include the title, description, location URL, thumbnail URL, and URL to the raw video file for video entries.
