First of All, the website/blog that your article is in must be well optimized for search engines, and it must be a legal blog/website because nonlegal ones are not likely to appear on search engines. Nonlegal: (Hacking-Porn-Drugs-etc...)
Secondly, try to add keywords in your article that people would search exactly with them, because if you had unique keywords used it your article, it is more likely to appear in the prior results of search engines
Thirdly, do not ever copy paragraphs from somewhere else and paste them into your article because in this case, your articles would never appear on search engines because you will be stealing contents.
