Types of Duplicate Content

1. Recycled Content: This is a basic example of duplicate content. This is where a writer, blogger or developer posts a unique and original content online only to use it again (maybe with some added paragraphs or sentences), and post it in another web page. Search engines have a very keen eye in finding these.
2. Published Article Duplication: This is especially true for writers who submit their original articles to web and article directories. Many web developers submit articles to these sites, in the hopes of gaining exposure for their content. The directories typically don’t charge for submissions, making them more appealing to website owners.
3. Web Page Duplication: As has been said earlier, duplicated content is not only confined to text articles but also includes other types of files and even web page styles. Search engines sometimes erroneously consider websites with similar lay-outs as duplicate content and exclude them from their search results. This is common with affiliate websites, which are usually patterned to look similar to the original website.
4. Paraphrased Content: Many web developers post similar content with just a few added sentences or words. Search engine developers, however, already know of this tactic and have already created algorithms that exclude these in search engine results.
5. Other Media Files: Search engines have now developed several ways to find duplicate content in all its varied forms including videos, images, and PDF files. Though not as reliable as the ones used in detecting duplicated text content, the technology is developing and in time will be as reliable in detecting other duplicated media as the ones being used with text articles.
