Google ranking is very important for marketing in general. If you are not among the top search results, chance is people never will find you. How the exact Google algorithm works is kept secret and is subject to frequent change. But some properties are publicly known. There are dozens of aspects to deal with.
Among these, one very important aspect is to avoid exact duplicate content. It is a matter of time, but the Google Bot will find duplicate content. Google will punish this behaviour and bans your website from the results. So at any cost, avoid using exact matching duplicate content.
This doesn’t mean you can’t use the same content. Just use slightly different phrasing, other verbs and synonyms to alter the content. This way you avoid being punished by Google and your website keeps showing in the results.
