You are always suggested to start your blog on a niche that you are really interested in, or you really know well. If it is so then you will never run out of ideas of unique content. Cause whatever a niche is, how much narrow is be, there can be easily 2-3k posts. Now if you are thinking to start a blog, or already have a blog where you take inspiration from other blogs and rewrite them with your own ideas, then only option you are left out with is to read at least 4-5 different posts on the same topic and then combine them with your understanding.
I completely agree with the above advice. Genuine interest in a niche makes it a completely different process. I think it also depends on your goals for the blog. Are you going for tons of comments and social media shares? Or a solid base of SEO-optimized articles and driving mostly search engine visitors? Is your target group of readers already knowledgeable in your niche? Or relative beginners? If you want to share a little more about what you're doing, we can better help.
So, you are running dry on ideas. I think this post might help you http://www.problogger.net/archives/2011/09/03/52-types-of-blog-posts-that-are-proven-to-work/
Do a blog that interest you the most, this way pulling up an idea is not really an issue. Though if you can't relate on the niche you are in and just established in because of the earnings, just hire some writers to do the work for you.
Well to make content Unique there is no way except to re-write or spin article... For Unique Idea you must use brain Its simple
See Wikipedia, other nice blogs(same content as your site) and adapt it if you really have no idea. Don't forget too add nice picture (relate to your site content) to make your site look professional.
Try looking for more keywords at Google Adwords. Long tail keywords are effective ones. This way you will know what unique topics to write for your blog and to know what topics catches the interests of your readers.
I think you should think of something that inspires you or you want to do. Isn't that a great idea for blog topics?
You don't have to write something unique all the time. I'm not saying you should always steal ideas, but just to add another dimension to the great advice of everyone else, you could also try to give your unique spin to a rehashed story. Find a useful resource that someone else blogged about? Why don't you improve on it, or try to make it funnier, wittier?
I agree with what someone stated earlier. Choose something niche-oriented, something you feel confident in talking about regularly, and something that you like. If you are going to be posting routinely, you want to let people know that your blog is unique and better than others with the same concept. Also, use your tone in your writing, or your "writer's voice." This will allow your personality to shine through and captivate your audience.
A unique post is something that you wrote entirely on your own. The idea or inspiration for the article could have come from the a movie, an article you read online, words from a song, etc. This is why most members in the thread have advised you to choose a niche that you have knowledge on or are passionate/interested about. This way, researching for new subjects to talk about in your blog would not be a chore.
