When talking about SEO (search engine optimization), image optimization is an important part of on-page SEO. As every SEO specialist probably says, that can bring some benefits and improve your rankings in Google.

Many of the website owners just put images with the name “dsc3244.jpg” or similar and don’t care about it. That is wrong. Of course, properly optimized images won’t give you much in the rankings, that’s just one factor, but if you want to have good website optimization, by missing out on factors like this, your overall SEO performance won’t be good, so your rankings won’t go well.

Now, let’s get started with the optimization tips:

There are 3 most important image optimization factors:

• Image name/File name
• Alt attribute
• Title Attribute

Image Name – The most important factor and you should name your images with words that describe what the image is, keyword rich and simple. As separator use “-“.

Example: “seo-packages.jpg”

alternate attribute:

The alt attribute of the image is important for SEO purposes, but don’t over-optimize it. Don’t try to put lots of small images and put keywords in the alt attributes. Google will punish that. So, just try to make it natural and look normal.

An earlier example was an image “seo-packages.jpg”. A good alternative attribute for that image can be “Affordable SEO Packages” or “Professional SEO Packages”.

The use of “alt” is to explain what is in that image. Also, if someone’s browser or mobile phone doesn’t support images, it will show their alt attribute.

Title Attribute:

In the title attribute, you need to put some descriptive text. For a given example, it should look like this: “Professional SEO packages at reasonable prices.” The image caption is also displayed on hover. Note that the title attribute does not carry much SEO weight.

Other important on-page SEO factors that have influence:

Subtitle text:

It will bring some SEO points if you put captions somewhere around the images, or in the text near the image. The text related to the image will show Google that the image actually fits where it is placed.

Photo size:

It doesn’t matter if you formatted your image to fit on your page, you need to add width and height in your HTML code. This will increase the page load time a bit. A browser will immediately know where the image will be placed and will continue to load other parts of the page while the image is loading. If there is no defined width and height, the browser will load that image completely first, and then other parts of the page.

Also, you probably know that it’s good to format your images to fit your needs and not to scale your image via HTML.
