I have not read your hubs, so this is strictly some things you might check. Be sure your hubs have a subject that will be read by lots of people and not only interesting to a few. Check your hubs for spelling mistakes, grammar mistakes and punctuation mistakes. Fix all of them that you find. THEN...have someone else read them and check for mistakes. Be brave and let them be honest! It will only help you if they are honest with you. All your hubs should be your own writing and totally unique. Go back and change those which are not completely your writing. You can get your hubs up to the best standards and with a little time, you will find that you are writing better and faster. Good luck!
