Optimization is very import in Blogging. And you have to optimize your blog completely from top to bottom for increasing the traffic flow. Blog traffic not only coming from web search but also from Image search. So we should optimize our WordPress blog image properly.
We can see the image by our own eyes but Search engine has no eyes so they can only understand the image by Alt Text. For Example if we add or upload an image of Apple in our blog then search engine won't able to detect the image that this is Apple. So when we add an Alt Text like this is pacific rose apple then search engine can read the Image that this is Apple.
Alt Text for Blog image is very easy to use. While you are uploading new image in WordPress blog then you would see a Box appear like below with image option like Image Title, Caption, Alt Text, and Description.
Though out main target is to adding alternative text or Alt text. So just add any alternative text there. But Image Title is also important try to add relevant image Title which is related to Post title.
How to add Alt Text in all Blog image automatically?
If you are Newbie then you may skip adding Alt Text option in your previous posts images. But it is now not possible to adding Alt text to all previous images. Because you have to manually edit all of your Blog Posts. If your Blog containing 100 posts then it is really annoying to edit each and every post. So the solution is to use SEO Friendly Images WordPress Plugin. It has free version and paid version. You can easily use free version to fulfill your purpose. For Installing this plugin Just follow the below steps-
Step 1 Sign in to your WodPress and go to DashBoard and Click on Plugins ->Add New

You can simply use keywords which can appear at the top of the image search page.
Limitations of the Plugin
When you upload an image in your WordPress Blog without any relevant image Title then SEO Friendly Images can’t work properly. Because according to your Image title it will generate the Alt text. So if you have already added Image title without Alt text then I recommend to use this plugin in your WordPress Blog. Actually this is not the limitations of the Plugin because by default when you upload an image then the title of the image will be 001.jpg so it is not possible to generate better Alt Text on the basis of 001.jpg image Title. So this problem may arise in case of all Image Alt Text plugins.
