Here is what I found. I pasted the article and set it as an "article/blog" with a 10th grade reading level.
1) It was great at spotting grammar, spelling, and punctuation errors and offering suggestions.
2) While not a Copyscape check, it did identify the article as plagiarized from ezin... and a couple of other article sites.
3) It identified that the article phrases did better than 20% of those at this education level (earning an "ouch" score)
4) It identified that 53% of the sentences were passive.
5) The use of transitional phrases ("one sign of an excellent writer") was better than 28% of those at this education level.
6) The vocabulary was better than 34% at this education level.
7) Overall it gave the article a high school grade of "C".
So after correcting the grammar, spelling, and punctuation I was left with several indicators that the article was poorly written based on a number of factors. But my suspicion is that an article this bad would need serious work to become "high quality".
OP should be given thanks for a useful tool, but this is not a quick fix.
