What is an ALT tag ?
By Kayleen West
ALT tags and why should I use them?
Alt tags are text descriptions on web images. These descriptions show up if an image will not display and are accessible to text readers used by visually impaired visitors.
Have you ever noticed a little description pop up when you place your mouse over an image. This may be an Alt tag or a title tag*. In Internet explorer will display an ALT tag as a tool tip*. Some browsers like Firefox do not display ALT tags in this way but they are still there hidden and serving a purpose.
Alt tags help some visually impaired visitors who need to use text readers to understand a page format and so should be used. They can't see the images, but can detect text in ALT tags. In addition to this they also help you rank better with search engines. It also helps your site in another way. When you have images loading up, the ALT tag will show quickly, giving people quick access to image links if you are using them. This speeds up navigation.
Search engines optimisation is all-important to the success of your site.
Search engines do not index images, whether it be text or a picture presents in image format.
Many people use images for their logo, business names and links so they can use more creative style fonts as many browsers will not read these.
To correct the problem we can add ALT tags to our HTML. The ALT tag is a description of the image.
ALT tags filled with keywords can also be used to boost your keyword frequency and by doing so help your rankings. Search engines do not penalize for using ALT tags or even for packing them with keywords. To be safe though you should adhere to the generally accepted rule by not repeating keywords more than 3-7 times.
So how do I make an alt tag?
By simple adding the following code into your HTML: alt=” description goes here”
Example (click on image to read):
when your images are loading it can look like this:
If you are doing this in a text editor on a blog like Blogger you will need to switch over to code view by clicking the HTML tab. See image below:
In saying all this I have my own personal sites to go over. I make sure I do it for others but neglect my own – Not good Kayleen!
*Alt tags and title tags are different. Title tags ensure a tool tip displays in browsers like Mozilla Firefox. See large image for both alt tags and title tag html.
* A tool tip is the little pop up description.
