1. Excellent overall writing skills in a number of different styles/tones
I have a very diverse ability in writing. I can write in nearly any style or tone you can give me an example of. My writing itself is also strong and engaging.
2. Impeccable spelling and grammar
Spelling is great, and they have software for that so no excuses. I also use Grammarly even though my grammar is good, it's not perfect, yet.
3. A deep understanding of consumers and what motivates them online
If you want it to engage people emotionally, I can do that.
4. Great research, organizational, and learning skills
There is nothing I can't research or learn about.
5. High comprehension of software like Microsoft Word and Google Docs
I can use both very well, and I learn quickly if I don't know it.
6. Familiarity with keyword placement and other SEO best practices
1-2% keyword density naturally using the keywords in the article.
7. Some experience with online marketing and lead generation
I have experience here, as well.
8. An understanding of formatting articles on the web
Not positive exactly what you mean by formatting on the web, but I'm sure we can get it.
The best tip I have for exercise is simple, and it's to just do it. Start now, today, and don't put it off. Do one push up if that's all you can do, then do two tomorrow. Just do something, today, right now. Most people fail because they never take a step, never take action. Do something, even if it's small and just get started.
