Guest Blogging Site Selection:

1. Did you carefully choose the website? - Focus on Site quality and future growth. You may need to work your way up.
2. Is the Guest Blogging site within your niche? - Need I say more on this?

Choosing the write website takes some research. Check for spammy links and former posts both from the author and from previous guest bloggers. Ensure this is a website you want to be associated with.

The Best Guest Post Article Creation:

1. Does the Subject match the readers needs?
2. Are your facts in order? - Be well informed and do your research ahead of time.
3. Is your post gramatically correct? - Proof read more than once or have someone else do a quick review.
4. How is your tone and context? Ensure your tone is somewhat neutral so not as to offend anyone.
5. Did you add in too many keywords? Don't worry about keywords. Guest posting is about providing insight and being helpful, not SEO.
6. Are you being self-promotional in any way? - Again, focus on the website's readers. It's about THEM, not you.
7. Is every aspect of your post unique? - Ensure you are totally unique. Run it against dupe and plagiarism checkers.
8. Are you promoting any of your products or services? Again, zero promotion - help your readers and earn respect and authority.
9. Are you right on the heels of your last guest post? Spread it over time, don't go on a guest posting spree.
