Your website images may well seem like a pretty straightforward part of your site.

There are however a couple of things to consider.

The alt text stands for alternative text and in website design it is used to provide an alternative text for images.

This has three main purposes:

  1. If your visitors are visually impaired having an alt text will let them know what is meant to be there.
  2. If for some reason the image can’t load or your visitor is using a browser that doesn’t support images then the alt text will give your visitor an understanding of what is meant to be there.
  3. Having an alt text and a good descriptive name for the image will improve the chance of your image ranking inside the Google image search. Depending on your website this might prove to be a significant source of traffic.

A few other things that you might want to think about when it comes to images on your site are making sure that your images are optimized to load fast on your website. It is an easy mistake to make that to upload an image straight from your camera but this is generally going to be far too large a file to show on your website.

So it is worthwhile both uploading a smaller image size and also saving it at a lower quality.

The other thing you might consider is having a secondary site map just for images.
