These SEO practices should of been avoided long before 2013, but I will go over some of them again. Writing very little content or thinking that you can just go and copy content from another website and use it as your own because you changed a little bit of it won’t work. Trying to jam a hundred keywords in your meta (Title, Keywords, Description, Alt Text, and so on) for a single page will not work. Stay away from link wheels, link farms, paid links or any linking strategy where it is not closely related to your type of business. By doing these types of strategies will not only not work, it will get your website in hot water with Google. Overall if you want to stay right with Google produce great content and stay away from anything that look too spammy.
