Auto blogging is the practice of using a script to publish the works of others for personal benefit, e.g., monetize mashed up content with Adsense, Amazon, or Prosperent. Auto blogging means that the results of the scraping process are stored in a database and are served as blog posts. Discussion in the comments may or may not occur, but the point of the matter is that auto blogging means that no original content was written or created. Rather, other people or news sources have generated the content and it is being republished with or without the expressed permission of the original content author.
Google hates this. Google punishes this.
Scraped content: Some webmasters make use of content taken from other, more reputable sites on the assumption that increasing the volume of web pages with random, irrelevant content is a good long-term strategy. Purely scraped content, even from high-quality sources, may not provide any added value to your users without additional useful services or content provided by your site. It's worthwhile to take the time to create original content that sets your site apart. This will keep your visitors coming back and will provide useful search results.Translation from Google: "We know about auto blogging. We will blast your domain from the search results if you do it." Now, before Google took such harsh action against auto blogging, people were making real money doing it. I had a buddy who was making $500.00 per month from Google's Adsense and another $500.00 from Amazon. (He was getting about 1,000 unique hits per day.) He would be contacted from his blog's contact form and would be sent products in the mail in order that he would write up a review for them. Now, he wasn't using an awesome template or anything. He was just scraping articles from articlesbase.com and was publishing content from Amazon's API along with Youtube videos here and there. For some reason, Google loved his domain and content, ranked him well in the search engine results, and the traffic flowed. And with traffic came real money.
Now all that's gone. While Google takes into account dozens, if not hundreds, of unique factors when calculating the "worth" of a page on the internet, scraped content seems to always count against the over all relevance of a page. Time and time again, Google recommends creating unique content. Google tells us to create useful websites, and even suggests that republishing content in small amounts is okay, so long as there are "additional useful services or content provided." This means that there must be a degree of original content on each page for Google to find worth and value in that particular page.
Now as I have said before, blogging is about the easiest way of creating unique content. The reason is simple: nothing is more unique than you and your perspective on things. Writing interesting pieces of information, offering advice, posting criticism, sharing poetry and short stories, talking about a foreign place or food, or even discussing your pet's latest escapades can be possible topics for original content. Google wants it -- lots of it. And if you do a good job of creating content, Google won't ban your domain from the search engine results page -- which means that you stand a nice chance of getting organic traffic. Organic traffic translates into real freaking money, folks. This is why even if you have the simplest blog, you should add some kind of monetization of it.
My evidence of this is Google itself. Google offers the blogger service for free, and it provides content publishers (blog authors) the built-in tools to freaking monetize their blog. Google wants you to monetize your blog, folks. Now, you can do that by blending in adsense with your blog's content. You can also do that by blogging about products found on Amazon or on Prosperent. The sky is the limit; actually no. That's wrong.
You are your own limit. :)
