I want to Highly Spin (Human Readable) some articles from other source and then I want to publish them on my website, for this reason I will use WordAI.com and you know that some times WordAI can't deliver 100% Copyscape passed unique content. So I want to know that "How Much Percent Copy Content Google Consider as Unique for Ranking"
Google is pretty good at knowing header, footer, LHS nav bar, and RHS column. This is fine, and expected. Imagine if it was a problem for rankings and every website started using a different header and footer and LHS nav and RHS column with different wordings on each page - users wouldn't know what/where/how anything on the site. As I said, it's expected to duplicate from page to page, it's one of the fundamentals of good website design - don't confuse your visitors, encourage a site-wide style and navigation to increase "ease of use", etc. So long as you are not duplicating your "main content" of the pages, you'll be fine. I wouldn't go worrying about what percentage it is, so long as each page has a unique theme/message/topic you shouldn't run into any problems.
I had this question myself not too long ago. I did some research with sites that rank decently and ran Copyscape checks against them and some of them with up to 50% copied content. As long as the majority of it is unique, I think you will be fine.
Thanks for your great replay with suitable answer. Thanks again. Thanks a lot for the details answer.
It depends on your sector / competition. 70% is ideal. But it's not just about an article on your site. It's about the total content authority your domain carries. In my experience, if your site carriers 90% duplicate content, a 100% unique article won't rank well. You can use Google Plus to rank pages that are partly duplicate. As long as you have strong author rank.
Well... I don't think there's a benchmark as you'll have to take other things into consideration. Search bots are good at reading synonymous these days. Nothing can beat manual spinning. You'll be writing using your own tone and voice. That's whats important these days.
Duplicate content is only duplicate when it is on different pages on your site. However, if you have an article you are using from someone else, you have 3 options: 1) syndicate it with link back to the site/author 2) content curate it, where you write an intro to the article and show a snippet of the article with a link to it, or 3) rewrite it completely to make it your own. If you rewrite it, we suggest adding your style/brand to the article and make it 100% copyscape passable. If the content is too much like the original piece, and you didn't credit the author, you may find them contacting you and reporting the site to Google. I tried spinners before, but it never worked out for me to create high quality content that keeps people coming back to the site, and in some cases, it takes LONGER to write! That is especially if you know the subject of what you are writing very well. I recommend finding content writers to write for you or writing off the cuff if you know the subject well.
