If you want your website to rank higher, and increase web traffic and engagement, below are some solid tips to SEO optimize your website images-

  • Naming Image Files Naturally

Naming your web images is the best approach to optimizing with SEO. Use simple names and the right keywords for the image, which will help in bringing traffic to the site. 

Suppose you have an online store selling handcrafted jewelry,  including earrings. For one of the images you have mentioned, “Silver Blanket,”:

Instead, you can also name it”image17797.jpg” or “earrings-seed-beads-woven.jpg” by using the right keywords matching the search terms that potential shoppers would use to hunt for your products.

Additionally, alt text and title attributes enhance the user experience by helping images rank higher in searches. This increases the page’s relevance and adds beauty to the website details.

  • Optimizing your Alt Attributes

When a browser cannot render pictures, alt attributes serve as a text substitute or alternative text. They are used for accessing the web. If you hover your mouse over an image, you will see the alt attribute text or alt tags.

Your website’s alt property improves its SEO value. You can improve your website ranking by giving the images alt attributes containing keywords. Using alt attributes is the best way to ensure that your e-commerce products appear in Google images and web search results.

Here are some tips you need to consider-

  • Describe your images in simple terms, like how you named your image file names.
  • Use model or serial numbers in your alt attributes if you offer products that have them.
  • Do not overuse terms in your alt attributes
  • Right Image Size and Format

Utilizing a variety of formats can assist you in managing the weight of your website. There are different types of formats you can select depending on the image size. SVG is an excellent choice for logos and icons. Also, it is lightweight and compatible with pictures and many colors.

PNG is the heaviest kind and works well with images with a transparent backdrop. The most famous image format is JPG/JPEG, which supports various colors and details. To prevent making the page heavy, you should keep JPG photos under 100 KB and 1920 px in size.

When saving a huge image, you can use the progressive JPG setting, which causes the photos to load. A webpage takes longer to load when the file sizes are larger. In case your website loads faster, there will be fewer visitors leaving your site. 

The “Save for Web” command in Adobe Photoshop is one approach that will help resize an image file. When using this command, you should consider image quality when adjusting the image to the smallest file size possible.

  • Using effective Digital Asset Management Solutions

A digital asset management solution can assist with picture optimization and image library organization. A decent DAM solution will help you manage your photographs by tagging them with the appropriate, searchable keywords.

  • Optimizing Thumbnails

Thumbnail photos are used on different e-commerce websites, particularly on category pages. They display things without consuming a lot of space. Thumbnails are great but use them with caution, as they can affect web traffic. 

Typically, thumbnails are displayed at pivotal times during the shopping experience. If the loading of your category pages loads slowly, you might lose a potential customer and your website SEO will suffer. Image compression can help the site to load faster.

Here is what you can do

Reduce the size of your thumbnail files as much as you can. Here, it could be worthwhile to sacrifice quality for a smaller file size. Remember that the total effect of your thumbnails will significantly affect how quickly your page loads and how to optimize your website.

  • Using Image Sitemaps

Image sitemaps will assist Google in recognizing the image, especially if your website uses JavaScript galleries, image pop-ups, or other “flashy” methods to enhance the shopping experience.

Web crawlers or bots do not crawl over web pages where there is no direct reference in the source code of the image. Therefore, you must include a location for hard-to-know photos on an image sitemap to inform crawlers about them.

Google has several guidelines for publishing images that could raise the SERP ranking of your website. Additionally, by providing Google with more details about web photos through Google sitemaps, you can make it easier for Google to find more of your photographs than it otherwise would.

  • Avoid Using Decorative Images

You will find decorative Google images on search engines, including backgrounds, buttons, and borders. Any graphic or image not tied to a product is considered decorative. Even having professional images can enhance a web page’s aesthetic appeal. Use a template that reduces file sizes and check the file sizes of all the decorative images on your website.

Here are a few things you can do-

  • Create simple patterns or border graphics as PNG-8 or GIF files. Use a few hundred bytes to make pleasing graphics.
  • Whenever possible, generate colored areas using CSS rather than pictures. The best you can do is, replace any decorative images with CSS styling.
  • Use CDN Wisely

CDN (Content Delivery Networks) is the go-to place for hosting images and media files. They can speed up website load times and assist with bandwidth problems. The only drawback here is its backlinks. Backlinks are essential for SEO, and the more backlinks your site has, the better it will rank in the search engine. 

By uploading your photos to a CDN, you are shifting the file from your domain to the CDN’s domain. Therefore, when someone connects to your image, they link to the CDN site.


Using web images to boost your SEO is the aim of optimizing the same. The method of image optimization depends on us. Alt text and formatting are essential parts of optimizing photos. A well-structured image enables the site to load quickly. 

Moreover, SEO helps to identify your image by using alt text. Your website can be found more easily by indexing your image. Search engine optimization is the result of all of this. 

Google has made us aware of these elements to improve a website’s ranking. The higher the rank, the higher the chance of getting traffic. The key lesson for picture optimization is still a recurring one.

You need to work on specifications for images and their formatting for rich results. Although you may customize images for the web browsers you select, those browsers change in popularity over time. Images can now genuinely increase page rank and drive visitors to your content by having the potential to create permanence. Every website that wants to increase its SEO must optimize its photos to draw searches.
