Must an article be 100% unique in order for Google to be indexed? let's say i copy an article from ezine and using synonyms to spin the article to 50% unique, will google still index the spinned article?
That depends on what percentage uniqueness Google counts an article as duplicate . I or any other person except Google staff don't know how their duplicate filter works.
50% enough to rank and index those articles.. I did same thing and got results. Try to change title as you can and manually and description. It will work.
If it is 50% unique, then Google should index it... Not only you, but many webmaster here do this trick.
i have found that content is preferred to be unique, but not always a requirement. That said, I have seen some articles not being indexed, and these tend to be the more copied ones
I think, its not necessary to have 100% unique content to be indexed in Google. I agree with Swasts that 50% to 70% is enough for this purpose.
30% + is enough, but 100% is the best. with a 30% uniqueness will be indexed but 100% unique article will get a higher rank in google then 30% one.
It's should be ok dude. However, it's better to mix the spinning method, synonyms approach and sentence level spin approach. then you'll get a better new article i think. there is easy-article-rewriter available in the net. may be you can try it.
I think its not that100% unique for Google to index the site but I think if its 100% unique then surely it will gain more benefits for you right...
Just use article spinner to spin your article....but make sure you can read your article after you spin your article....
Hi, In my own experiences, Google would index them but would not give a nice weight for them neither for PR nor for SERP purpose. all the best,
