How to Use the Alternative Text Tag to Describe Your Images

Every time you add an image to your blog posts or webpages, remember to add a description (“alt tag”) of the image in the right place. The alternative (or “alternate”) text tag will make the search engines understand what the images on your website are about, and also help your images to show up in Google Image search for relevant keywords.

Note: Depending on your images and type of industry, you might not want to get indexed in the Google image search. For many industries it’s known to be a good source of traffic, so you decide what’s best for you. If you don’t want your images to get indexed, you should still use the alt tag for your images and rather use robots.txt to block the Google image bot from indexing your images.

How to see your alt tags

Let’s take a closer look at what we’re talking about in this blog post:

1. Login to the administrator area of your website.
2. Open one of the articles (that has an image in it) in the article editor.
3. View the html code of the article (should be easy to do directly in the editor).
4. Find the html snippet for the image (see below).

Your image tag/code probably looks something like this:

<img src="image-name.jpg">
