Plagiarism on the internet:
Remember what a big deal plagiarism was in high-school? It’s an even bigger deal on the web – and easy to detect. Aside from the ethical issues, it can also seriously effect your SEO (search engine optimization). Google accounts for 100 billion searches. How you rank with them, is determined by A LOT of things. Duplicate copy content is one of them – even if you have permission to use someone else’s. This can be remedied by modifying the meta data in the post or page. Using a “no-follow” line of instruction will tell Google not to crawl that page or post, but it will also prevent that document from being searchable on the internet.
So, if you pay a third-party for copy content (i.e. blog posts) make sure that they are creating original content for you. According to Ross Jones of 2 the Top Web Site Design & Promotion, one way to run a check on your own, is with copyscape.com. You can run a free search of any page or post, or pay for an automated detection system.
