Constant Improvement For SEO-based Articles

Even though it is far from perfect, I am currently stoked with Write Sonic. So here's my plan to write content daily and post it on my website blog: 

Main Priorities: 

1. Achieve 100% originality. 
2. For product reviews, ensure correct dimensions and summaries of the products. 
3. Write a meta-description. 
4. Include text alt-images. 
5. Collect outbound links and paste them into the post. 
6. Create internal links if possible. 
7. Upload 1-2 images. 

Next steps (constant improvement each week/month): 

1. Add subheadings. 
2. Shorten sentences. 
3. Use more active sentences. 
4. Add extra key phrases if needed. 
5. Aim for a Flesch Minimum score of 60. 
6. Add more images. 

I'd love to hear other's suggestions.
