Search engines don't read images. Therefore, we use alt tags to read images by search engines is called image optimization.

 

Image optimization is the way of making images more search engine friendly which are to be used in your website.It is a part of on page optimization.As we know that google do not read images but read only alt tag. So Images must have alt tag and it should be in proper format. it must have particular name. for example if we are using image for header than its name should be header.jpg.

 

According to me, Image optimization is another part of Onpage optimization. You just have to Create descriptive alt text and Make sure the image matches the content.

 

image optimization means adding alt and title tag for all images because google does not read image it read only content.

 

yup, just fill the alt, title, and tag with your keyword (related with the article) ... you can fill the caption too for image optimization

 

The alt attribute to provide descriptive text. In addition, we recommend using a human-readable caption and descriptive text around the image.
search engines have the same problem as blind users. They cannot see the images. That's why we are optimizing the image.

Here is the enlisted some additional thoughts about optimizing the images.

1. Image Naming: Use a descriptive name for your file. You should use your important keyword in name of the image. If you are using a long filename you can use hyphen instead on underscore as a keyword separator. For example if you have any image about diamond stud earrings you can name it as diamond-stud-earring-for-sale.jpg instead of non-sense jewelry12548.jpg or just earring.jpg.
2. Alt for Images: We all are aware about this tag. We should use a descriptive and appropriate alt text as search engine use this text for reference/information about the image. Additionally your alt tag is displayed on web page when someone opts for not showing images.
3. Title Attribute: Use a descriptive title text for your image. You must include your keyword in title tag as it is an important point in image optimization.
4. Surrounding text: The text which is used around the image is very important as it adds the relevancy to the image. So must use relevant and keyword rich text around the image.
5. Description Attribute: You can use a long Desc attribute to describe the image in detail. It will help to provide information about the content of images.
6. Heading tags: The heading tag used on the webpage help in getting ranking for the webpage as well as images. So if the image is very important, you can use the relevant heading tag on the page.
7. Incoming links: Just like web promotion, we should add incoming links for the image. Use your targeted keyword with some variation for back links.
8. Use the image on relevant page: It helps a lot. You should use the image on the relevant page. For example like above, if your image is about the diamond stud earrings, it is better to use that image on earring page like diamond-stud-earrings.html
9. Enhanced image search: For optimizing your images in Google, just log in webmaster account and activate the enhance image search feature.

 

Image optimization is nothing but giving alt tag to the Images we are using to promote.
If you are using the alt tag then when anyone searches they will find your images

 

Its one more technique to promote your website.
