Image optimization is on-page part of SEO. As probably every SEO specialist knows that proper image optimization can improve Google position. Image optimization is one of the basic guidelines in web design. By using image slicing and reduction, you can make your image size smaller, so that images load easily on the browser without taking much time. A right use of width and height technique for your images will result in faster page loading.
The 3 most important image optimization factors are Image name / File name, Title attribute, and Alt attribute.
Image Name:
There is no software in this world, who can specify an image. If you put the image of cat on your web page, a search engine is not able to determine that this image is about cat or dog. Search engine checks the relevancy of a page on words. So, the first important point is that you should name your image with words that describe it properly. For example, “SEO Company India.jpg”
Image alt attribute is another important factor in SEO but remember that you should not over use it. Some people try to put many small images, and they put keywords in alt attributes. It is a bad practice. Google may penalize your site for it. So use it in the situation where it is needed. If you see previous example “SEO Company India.jpg”, a good alt attribute for it may be “Internet Marketing Company” or “Seo Services India”. Alt attribute is use to explain what is on the image.
Alt attribute:
Image alt attribute is another important factor in SEO but remember that you should not over use it. Some people try to put many small images, and they put keywords in alt attributes. It is a bad practice. Google may penalize your site for it. So use it in the situation where it is needed. If you see previous example “SEO Company India.jpg”, a good alt attribute for it may be “Internet Marketing Company” or “Seo Services India”. Alt attribute is use to explain what is on the image.
Title Attribute:
You can use title attribute to put some descriptive text. For an example, it should be look something like: “Seo Services India gives quality service at cheap price”. Title attribute in SEO is not so much important as discussed earlier two attributes.
Image size:
To format your page according to your web page, you should use width and height into your HTML code. It may increase your page loading time a little bit because the browser know in advance, where is to put image in the page. Firstly, it will load all the text, and then it will load the image. If you do not specify an image with height and width attribute, the browser, first, loads your image, after that, it will load other parts of page.
