When you upload images to your blog posts I suggest you follow these tips below:
- Name the image after a keyword you plan to rank for. You may use LSI keywords instead of the main KW you plan to optimize for.
- Use an appropriate title based around the keyword or keyword phrase you want to rank after.
- Fill in the description. Again optimize it around the context of what you are writing all about.
- Fill in the ALT tags with a sensible keyword based on the topic you are writing about.
