About SIO

What is SIO (Search Image Optimization/alt attributes )

The purpose of alt attributes is to provide a description of the contents of an image file. One of the most cited uses of alt attributes is to provide text for visitors who can’t see images in their browsers. This includes visitors using browsers that cannot display images or have image display disabled, visually impaired visitors, and those visitors who use screen readers. If a viewer can see your images, alt attributes will also show when the user hovers over your image.

If images do not show in a browser, for whatever reason, the alt text will show in place of the images, giving context to what the images actually contain for those who can’t see them.

How Alt Attributes Help Search Engine Optimization

Just like the visually impaired, search engines can’t see images on websites. Even if an image has text embedded within it, search engines are unable to crawl that text. So by not creating alt attributes for each and every image on your site, you lose a huge opportunity to be as visible as possible online.

But in just what way do alt attributes help SEO? Search engines use the information that alt text provides to determine the best image to return for a search query. This is a great way to bring new visitors to your site and it helps to increase your rankings with the search engines. In the process, you will also give yourself an SEO edge on your competitors.

Thus, alt attributes are a great place to utilize your keywords and help increase your chances of showing up in image searches. However, make sure that the attributes are appropriate for the image. For example, you wouldn’t want to label an image of a dog with alt text “affordable digital marketing services in Sioux Falls” — this just doesn’t make sense. If you try to trick search engines like this, you could actually hurt your SEO instead of help. So be true to your images.
