Issues Addressed in Panda Update

·   Poor Content– Weak pages with very little text and relevant resources or names, such as a set of pages describing a variety of health problems with only a few sentences on each page.

·  Content Farms- it is a practice or tactics of hiring large number of freelancer content writers to produce a high volume of textual content according to the search engine algorithm in order to rank in SERP. The limitation of the content farming in volume of content is high but its relevancy is low.

·       Duplicate Content- Copied Content that appears on the Internet in multiple locations. Duplicate content issues can also occur on your own website when you have multiple pages with the same text with little or no variation. 

·   Poor quality content- pages that are of little value to human readers because they lack detailed information.

· Lack of authority/reliability: content produced by sources that are not considered definitive or verified. A Google representative said that sites designed to avoid the impact of Panda should work to be recognized as authorities of their subject and entities with which a human user would feel comfortable providing information from his credit.

·  Poor Quality User-Generated Content: An example of this type of low-value user-generated content would be a blog that publishes blog posts for guests that are short, full of spelling and grammar mistakes and missing Authorized information.
