How to: write a fancy blog post in 10 tips

Empower your message and clarify your opinion by following those few tips:

Substance

Develop a unique and documented standpoint: your post has to bring something new to the party, whether it is your personal skills, your experience or your disruptive opinion.
Help your audience: don’t be generic; your post has to meet the needs of a specific audience. You may use metrics to narrow this audience and find out about its expectations.
Put yourself in the mindset of your reader: increase your post’s user value by thinking like you are the reader.
Don’t be tacky: preserve your credibility by avoiding any coarse or indelicate catchphrase.

Organize your post: order your content into sections and paragraphs; those will make your post easier to read.
Pick up a relevant image: a visual illustration triggers emotions and makes your message more powerful.
Enrich your post with links, data, expert quotes, customer testimonials, opinions of influencers, etc.: your credibility will be increased and your standpoint will appear stronger.
Optimize your post: carefully choose categories and tags that will make your post easy to reference.
Call-To-Action: involve your reader; comments,...

Most importantly: have fun and be passionate about what you're writing. It's all about sharing, enjoy :D
