If I say it once, i say it twice, if not three times a month.
Duplicate content is a big no in the world of SEO, so just think before you decide to copy content from somewhere else. You may think that it is an easy thing to do at the time, but when Google catches you, the penalties for your site could range from a mild filter through to a full site penalty.
Surely the last thing you want to see is years of hard work down the pan, just for the sake of spending time writing your own content. I am not saying that it is the easiest task in the world to fill your site with lots of unique, relevant content, but look for novel ways of doing rather than attempting to ‘cheat’ the system.
Always stop and think before you contemplate duplicating !!
