Prioritizing grammar is the key to your success. Nobody wants to read an article flooded with ear-tearing grammatical errors. You can also change the format to make it fresh and new. Next tip is to read it out loud word by word to spot the error.
Next tip: Do not depend on spell-check alone because it does not guarantee a grammatically correct content. Also, disengage from what you have written and allow yourself to be corrected. Everybody needs improvement. The internet provides plenty of proofreading tools – use them.
