Organic Traffic Dropped at Year End.
 

Help: Can anyone explain if there is a possibility that the organic traffic and keyword ranking can go down during festive season or year end?

The penguin update has already been rolled out and I have read somewhere that Panda is also in progress and will get rollout in coming days but not sure about the date.

Is there an effective to check out what exactly is causing the harm?
Appreciate your response.

It depends on your business, website, targeting keywords and market. If you have an e-commerce website then NO because this is shopping season. In this season traffic and keyword ranking go up of the most of the ecommerce websites. If dealing with ice-cream selling business then definitely can go down. No doubt.

it depends on many factors i suppose

This is a business website. Static content. Is there any way I can find the cause for the decline.

forget keywords and just focus on your website structure.

Focus on website structure, this will help you.

Thank you all for your valuable response. How long does it take to get the sitewide links removed using webmaster tools as I have noticed few sitewide links.
