Steps to do Blog Posting
- Keyword Research
- Choosing the right title
- Attractive Images with proper Alternative Text
- Product Related Video
- Choosing Proper Sub Headings ( H2, H3..)
- Making proper Interlinking (Incontext link to your website)
- Picking proper Meta Keyword and description
Make sure to write unique and interesting article based on the taste of your visitor's.
IMO, you do blog posting in your own website by creating "blog.yourdomain.com or yourdomain.com/blog" instead of doing some other blogging website like blogger, wordpress, blog etc.
