Screen readers used by visual impaireds or narration software and web crawlers use alt tag (also known as alt text) to understand what an image is all about. Similarly, when a browser fails to load an image (due to slow connection, etc.) this is what the browsers show on the screen.
On varvy SEO tools, I once read:
“The more you optimize your posts and website for a blind, the better the search engines will understand your content”
So true it is.
Back In January, I wrote a post on some of the best alternatives to SEO friendly images plugin in which I found two plugins which were:
- SEO Image toolbox
- SEO Image Optimizer
to be very effective in making images you upload on your WordPress blog SEO friendly by automatically inserting ALT tags in them.
In this post, I’ll share with you a full tutorial which will include how to make your image SEO friendly, and most importantly, automatically.
I use SEO Image Toolbox on BforBloggers. The first thing you need to do is install the SEO ImageTool box plugin. This one plugin is enough to handle all your Image SEO optimization efforts. Surprisingly this plugin also helps you to optimize your links so that they open in a new tab, helping in bounce rate reduction of your blog.
After you have installed the SEO Image Tool plugin, go the tools menu from your WordPress dashboard. Here, all you need to do is click on the button update tags.
Once you click that, it will take a few seconds for the plugin to update alt tags of your each and every image. Here in the screenshot above, you can see how SEO image toolbox updated a total number of 668 alt tags. This includes images that were having alt tags already and those too which didn’t.
Click on the save settings button to save the new alt tags. That’s it. From the SEO Image Tool Box will automatically generate alt tags for each image you upload based on their name. Remember to rename your image the same as you would like to have your alt tag to be.
SEO Image Optimizer is another good plugin which is more advanced when compared to SEO Image Toolbox.
You can also install this particular plugin if you wish to have more control over your image alt tags. If you wish to choose this one, here is the tutorial.
Go to the SEO Image Optimizer menu from your WordPress dashboard. In the plugin settings, you have to enter what exactly should be added to your images as alt tags. The available values are:-
- %Site Name
- %Image name
- %Post Title
- %Post Category
- %Post Tag
The settings of the value for the appropriate automatic alt tag generation would be
- %Image Name
Do not add the %category or %tag values. It will get you in the trouble with duplicate images.
Click on the save options. That’s it. From now onwards every time you publish a post, SEO Image Optimizer will automatically insert an alt text in each of the images you insert in your post. The best part, this plugin will also compress your images without reducing their quality hence making your overall site more SEO optimized. Always remember to name your images exactly what they are about.
