The latest version of Google Panda has released on 25 September; this algorithm has designed to filter or penalize thin or poor content and give their users best result. Because of this algorithm update 3%-to-5% of search queries will be affected.
Google says it’s expected to be more accurate and will allow more high-quality small and medium-sized websites to position better. From the post:
Google Said That:- Based on user (and webmaster!) feedback, we’ve been able to discover a few more signals to help Panda identify low-quality content more precisely. This results in a greater diversity of high-quality small- and medium-sized sites ranking higher, which is nice.
The rollout indicates anyone who was punished or penalized by Panda in the last update has an opportunity to appear, if they created the right changes. So if you were hit by Panda, created modifications to your website, you’ll know by the end of next 7 days if those were excellent enough, if you see a rise in visitors.
This algorithm also indicates that new websites not formerly hit by Panda might get affected. If you’ve seen an unexpected visitors fall from Search engines this A week, or observe one in the future, then this newest Panda Upgrade is likely responsible.
