There's a lot of things going on with Private Label Articles (PLR). Webmasters usually overcome the duplicate content filter by having other items such as syndicated news, blogroll, some affiliate ads, and some dynamic content in the sidebar. The idea is not to have exact duplicate websites. People notice that syndicated news are indexed anyway so there is no worry about having some duplicated article as long as the overall website is not different.

Another technique that people use is that, some people run these PLR articles through a software that would alter some words and replace them with synonyms of these words. This is a very creative solution to have a unique content.

Let me give an example on how these softwares do that.

Example.

"The quick brown fox jumped over the lazy dog."

The software might generate something like.

"The speedy brown fox leaped over the lazy dog."

This is the current trend nowadays with PLR articles.

My prediction is that the search engines will develop algorithms to detect these duplicate articles. Their AI technology would catch up and somehow penalize these sites that have duplicate articles in a large portion of its web pages.

It could be a page penalty, or a site penalty. Imagine, if a website has 100 out of 110 pages based on duplicate contents, then the search engines might think of this website as "not credible" or if its just one duplicate article, the search engines might just delete that one article in its indexes.

In response to this the makers of PLR articles will create a new kind of software that has some unique AI capability. Give it a topic (ie, a keyword) let's say "car insurance" and it will search the internet for content and sentences with "car insurance" in it.

The software will then group together sentences of the same topic, create a topic sentence and generate supporting sentences to create a new paragraph. The software will do this a couple of times to generate 4-6 paragraphs and then you get a fresh newly created article for your website.

Now this would be a hard one to crack by the search engines.
