Do you mean you have duplicate content on your site- Yes. I have republished few useful articles. So how to avoid search engine penalty.
Take the duplicate articles down. If you own these articles, the you need to re-write these articles if you want to use them on your site. If they are originally published on another site then you can quote blocks of text from the article but you need to link to your source. Hope that helps. Have a good day!
That's exactly it why you're penalized by google. You "republished few useful articles" instead of just curating the articles and linking your readers to the useful articles you want them to read. make sense? You can either take down the articles, or you can EDIT the articles and just curate them properly. Here's guide on how to do it. http://curationsoft.com/curationsoft-demo/ The official site of my favorite software which really gives me the benefit of content curation. Watch the second video how he curate other blogs useful articles and make his own article OUT OF IT. As I've said you can either take down the articles or just EDIT IT, why? Because google itself releases a feature in Google Webmaster Tool, called "Submit a URL to Index" I think its on year 2011, which google confirms and says "Will usually crawl or RE-crawl the URL within a day".. You choose. Goodluck with your site and hope you'll be penalize never again.
It is depending on many factors. Like your domain age, domain authority, percentage of duplicate content. Domain Age & Authority: If your domain is new and you are practicing these activities then it would be dangerous for your new website but if you’re having old domain than there is less chances to get penalize. Your old domain should have good authority and as a result it may perform well in-spite of having small percentage of duplicate content. But you should be ready to face some problem if you keep posting duplicate content. % of duplicate content: One more thing you should take care about is; percentage of content you just coping and pasting on your article. Look, it doesn’t matter for search engine (especially for Google) that you providing source link to original post; “COPY IS COPYâ€. Google crawler visits your website and will catch your content as HTML and if it won’t find canonical URL in your article for original poster than your future would be dark. You may rank higher on search engine for short terms but day-by-day your site authority would be decrease.
When it comes to curation, you can add videos, images curated from various resources. If you are making an article, then put videos in the article and along with ALL bits of various blogs and add my OWN commentary in making an article does that mean COPY IS A COPY for you? I can really see your point man, but you're just talking about copying from 1 source, copying a bit from 1 source. It doesnt work that way. I really have to disagree of what you're trying to prove mainly because I already see lots of blogs old or new dominated their niche just by curating articles and adding some curated videos some self commentaries not to mention I've seen results with my blog curating contents. But just to clarify not all articles will be curated articles. LOL Of course you'll want to provide your own useful articles too. The most important part is as long as you're providing your readers the information they want, may it be curated or own original content then for sure google will love you.
Look everyone has their own opinions. I explained this as per my experience and knowledge and you as your own. My main vision is to provide unique and quality content to my readers, of-course we can refer few images/videos there but as I said before % of content is more important. According to me small portion of curated content might be okay, but mainly I would like to serve my own quality content.
We have different visions as blog owners as long your successful on what you're doing then good for you.
