If we talk about “SEO” or Search Engine Optimization, I believe most of you have already know it in detail. But unfortunately, I found that a lot of webmaster (including blogger), missed another simple way regarding SEO. SEO for image! We forget that search engine is not only use to search for site’s content, but some people use search engine to find images too. In this post, I want to share my little knowledge about SEO for image.

These SEO for image tips is really easy, and do not need a special skills at all.

• File name
  When we upload image from our personal computer, sometimes we do not care about the file name. For example, you want to show image of your cat. You probably did not rename the original file name taken from your camera. It is exactly decrease your chance in winning an image search good position. It must be better if you name your file as “persian_cat.jpg”, “funny-kitten.gif”, and so on.
• Alt function
  Another simple but usually forgotten is in term of using “alt” function within an “img” tag. The “alt” function has two main purpose. First, it very useful to describe your image when your site’s reader do not activate their image. Second, the most important, this “alt” function used by image search engine (google and yahoo) as another point to increase the position.
• Title function and Slash (/) at the end of “img” tag
  I am not so sure that title function and the ended slash can really helps in SEO for image. But, this tag and ended slash is a must for every image in our site to make sure that our site is a valid W3C site. Since we know that having a valid W3C site is another way to increase our position, it is better if we do it correctly.

Let’s take an example at these SEO for image tips. Imagine, you want to show your own cat in your  personal site. You take a photo of your cat using your pocket camera. Before seeing these tips, you probably use this kind of img tag :

<img href=”http://yourdomain.com/DSCN1550.jpg” width=”400″ height=”300″>

The img tag above can make your image shown correctly in your site. But, it is not an image search engine friendly. Now, after reading these tips, I believe that you will write an img tag as below (see the bold) :

<img href=”http://yourdomain.com/beautiful_funny_cat.jpg” width=”400″ height=”300″ alt=”beautiful funny cat” title=”beautiful funny cat” />

By doing this SEO for image tips, I hope you can take an advantages and find that all images that has been uploaded within you website can be indexed clearly in some major image search engine. Have a nice day pal!
