how to do SEO Friendly image optimization

For Image Optimization, follow these steps.

 Image optimization with an alt tag

  • As alt tags tell Google about images, your images need to be optimized by image alt tags so that Google search engines can understand your images what your image is about, which helps rank your image in Google search results.
  • To provide more contexts to index your image in search engines and better user experience, use keywords in Alt tags for one time that users search. Make sure you have used the same keyword that is used in the full content.
  • Describe your image to the alt text’s point, and the image description should be up to 125 characters. For example, if you have a technology website and have to Google smart speaker image, you will optimize this image with an image HTML alt tag by using the primary keyword that you have used in your content of the specific page in your website like

<image src=alt= “On-page SEO Top 9 Rules & Best Practices”/>

So the above alt tag has a keyword “Google smart speaker” that will tell Google this image is about the smart speaker, and without alt text, Google will not understand your image, and your user experience would be bad.

 Image optimization with the title

Your image title should be to the point and have a structure and keywords to optimize it. For example, if you write the title of the smart speaker, then you will optimize your image HTML title tag in such a way like;

<image title= “on-page SEO”

So in this example, the title has a keyword, is to the point, and has a keyword and structure.

Optimize the image URL

As the browser needs the URL of any file to index it like this, images also have URLs, and they also need to be optimized with your keyword. Two things make these URLs.

  • Filename
  • Where it is directly uploaded

The file name is the keyword you assign to a specific image when you upload it on your desktop. For example, if your image file name is goggle smart speaker and it is uploaded on, then you can optimize the image HTML URL in such a way like;

<Image src=”https://techsaa.comon-page.png/>”

In the above example, “” is an image location where it is directly uploaded, and Google-smart-speaker.png is the file name of the image, and these two things combine altogether and make your asset or image URL.

Image optimization with the caption

Like this, you can use caption and image optimization that tells a short story or description about your image that what is going on in your image.

Importance of quality and relevancy of image

If your image has relevance to your content and quality, your user’s retention and conversion rate will increase, and Google will increase your ranking. When your image is relevant to your product description and has quality, your user will retain it on your website and ultimately convert it into your client.

speed and responsiveness

  • Google already factors in site speed in their search engine rankings. Google measures the speed of your website, that is, how much time it is loading. Images are one of the SEO factors that affect your website’s speed, so your images need to be loaded faster in search engines. If your website images are loading slowly, it will slow down your website speed, and Google will penalize your website. Penalize in the sense that it will not rank your website and your competitor’s website that loads faster.
  • Page loading speed increase or decrease the bounce rate of your website. As images take more space, loading time and affect your website speed, if people come to your website and are loading slowly due to images, they will not stay more and exit your website. If people exit your website, it will increase your website bounce rate. To increase the retention rate, you need to increase the loading speed of images that will ultimately increase your website speed. For example, if your website takes 1s to 3s loading time, then the bounce rate of your website increase to 32%, such as
  1. 1s to 3s————bounce rate 32%
  2. 1s to 5s————bounce rate increase to 90%
  3. 1s to 6s————bounce rate increase to 106%
  4. 1s to 10s———–bounce rate increase to 125%
  • Images size needs to be optimized to decrease the bounce rate and increase website speed as images take more space on your page. If you don’t optimize image size, it will slow down your web page loading time and badly affect your SEO.
  • To resize and compress your image according to your website dimensions. Your image size should be SEO friendly, and it should be up to 100kb, and its resolution should be 1920 X 1080. Seo-friendly images quickly load on your site and increase your site speed, and ultimately Google will give you ranking in its search results.
  • You can resize and optimize your image size by photoshop; Google frees online resize image tools and websites such as or WordPress Paid Plugins Like smush, etc.

Image responsiveness: Image responsiveness is essential, and you have to make your images responsive to desktop, mobile, LCD, Tablet

Formats and types of Seo Friendly images

If we talk about image formats, they are available in png, jpg gif, SVG. You have to use the lightweight, quality, and standard web format of the image to load on your website speedily, PNG format. Nowadays, many people use SVG images for their websites as they don’t pixelate and remain scalable when you big these images.

By following these image optimization rules, you can rank your website in Google as it is an important SEO factor, and Google pays more attention to it.
