Article Spinning is used by bloggers to take content online and have it “spinned” to change it and then post that new article on their blog. While I advocate writing your own unique content, this tool can be useful when you are trying to optimize a particular Keyword Term. You can use your own blog that your wrote, let’s say on your FARM area. You can spin your own article, using the same Keyword Term and blog that article in a different format online.
This service used to be a paid service only, so having a free tool is a nice time-saver.
Duplicate Content Locator
You are blogging and writing unique content. Do you want to see if anyone is copying your information? This site does a search online to see if there are any duplications online. While you can Article Spin, copying text word for word may not help in the Google Rankings when using Blogging techniques with Area of Expertise, Community Blogging or Paying it Forward Blogging. Use this tool to see check content for duplication on the web.
