Panda Algorithm
Panda first launched on February 23, 2011, and it was a big deal. The purpose of Panda was to try to show high-quality sites higher in search results and demote sites that may be of lower quality. Links are most likely not a part of the Panda algorithm. It is all about on-site quality.
What things we can avoid to avoid panda
Thin content: If you have a large number of pages on your site that contain just one or two sentences and those pages are all included in the Google index, then the Panda algorithm may determine that the majority of your indexed pages are of low quality. Duplicate content: Google is pretty good at figuring out that you are not the creator of this content. If the algorithm can see that a large portion of your site is made up of content that exists on other sites then this can cause Panda to look at you unfavorably. And to fix this problem use something called a canonical tag. For help to how to use canonical tags here is reference: https://moz.com/learn/seo/canonicalization Low-quality content: If the majority of the pages on my site contain information that no one is engaging with, then this can be a sign of low quality in the eyes of the Panda algorithm.
