It is good practice, but much better practice, if you rewrite the pages you are referring to.
Even just a few lines throughout the article will help make it more unique, otherwise it may end up
being a copy of someone else’s blog, who may not have taken the time to do what I have suggested.
I personally do not recommend an article spinner, as they do not work well, and are often more time consuming than not…. It is much easier to change wording etc, as you go along and read what you have copied. Most blogs will allow you to save drafts, use that option until you are happy with the final result!
