Hi,
Something that is interesting for webmasters, and SEO.
Google announced a new algorithm change to reduce the ranking of 'perceived' spammers.

This latest update appears to target keyword stuffing (lists of keywords) and article spinning.
This will reduce the rank of the website with spam keywords in their content.

This is nice & its will more effect on SEO. Thanks for sharing.

            Thanks for the share. I have read articles related to google latest algorithms for spammers and I also found some decrease of search results. Well I am looking for some help in this problem. If someone's website lost its position in Google searches in these days what would he/she do .

This new update is know as Penguin. It caused a drop in rankings for a few keywords in SERPs for a site of mine.
