Share this Image On Your Site


Images in an article, blog, website or any postings can bring life to it. Images are powerful communication tools for the website, as they help tell stories, elicit emotions and also help in leads and conversions. But just using images without optimizing it right, would not be of any help to your business. Hence optimizing the images is very much necessary. In fact, image optimization is one of the important factors of the SEO campaign of any business.

Did you know?

Size of the images can have an impact on the website’s speed. According to a source, images make 54% of the total webpage’s weight.

SiteGalleria has listed some of the very important image optimization factors below. Have a look at it as images can be a good source of traffic from Image Search engines such as Google Image Search and etc..

1. Use Right Image And Right Name

  • Always use relevant images as per your content and use more of original images than stock photos especially when describing your work, products, and team.

  • Also, use the right file name for your image instead of a random image name. This tells Google what is your image about without looking into it. It helps in driving traffic to your website.

For example, if you have an image of a sunrise seen through the window, then use image name/file name as sunrise-seen-through-window.jpg instead of DSC3214.jpg or anything as such.

2. Be wise with JPEG & PNG formats

  • Use JPGs where you need to display photographs and high-quality images with lower sizes.

  • Use PNGs for graphics, icons, and images that need transparency support, as they do not lose its quality like JPEG does when it is compressed.

3. Leverage Caption and Alt Text

  • Alt tag is a very important image optimization factor as most search engines are text-based and cannot read images. Alt tags tell search engines what is the image all about. The main purpose of Alt tags/Alternate text is to give information about the image to the user when it can’t load for whatever reason and it was added specially for the blind people.

  • Captioning images helps users to understand image better and also can be user engaging. Captions are also crawled by search engines like URLs. So, use captions as per the purpose.

4. Image Size Matters

Make sure, except for the larger images, the size of the images is below 1MB. Optimizing images by uploading that are the same size as they will be displayed is very much necessary. Images could be Cropped according to the screen parameter before uploading.

5. Use Right Image Compression Tool

We recommend not to use Gzip compression tool for compressing images as the image formats available in the web are already compressed and gzipping can hamper the quality, make images bigger and it is simply an extra work to CPU.

Use or compressnow or other such tools for a non-Wordpress site. And for a Wordpress site, there are various plugins like, WP Smush, etc.

6. Tell Image Size To Browser

Browser layouts the content around our images. Hence, it is recommended to always specify your image sizes to the browser as this can save from browser doing the additional work and it saves the loading time.

7. Avoid Image Hotlinking

Hotlinking images is the process of using images of one site, on pages of another site. This can steal the bandwidth of the hosting site and also can result in copyright issues. Hence, Avoid hotlinking images and also disable hotlinking of images on your site through the htaccess or web server (Apache) configuration.

8. Use Image Sitemaps

Wondering what is it? Using a separate sitemap for images or adding image information, i.e image-specific tags in your existing sitemap. This tells google about the information of the images in your site. Google has clearly mentioned its importance and how to implement it.
