Based on Marketing Land article, Matt also told them that “Panda 4.0 affects different languages to different degrees”, In English for example the update will affect 7.5% of the queries, which is the biggest since Panda 6 on Aug. 12, 2011, which impacted 6-9%.
The history of updates proves that Google is all for quality content and paying attention to every detail on your very important, especially rich content and originality. The update mainly focuses on on-site issues, how relevant topics are to queries and content performance.
Now going back to the main question Should we be scared of the release of Google Panda update?
TBH, I think only websites with less content, websites relying on external resources only, should be scared of the update and WILL be affected,
So far there is no clear understanding of the update, and we’re left in the dark, but playing with Google’s rules is the safest thing to do to benefit from Google Panda 4.0 update, always keep in mind to:
1- enrich you readers with original and rich content.
2- Avoid duplicate content
3- Avoid spam content
4- Put a strategy for your blog
5- Make sure your focus keyword is relevant to you title, content and even URL
