When did you find the changes actually we had a Panda update on November 5th 2012 and thereafter nothing ...
google has been releasing lot of updates. hard to say why your ranking is down as it would depend on since when your site started to go down in ranking, what has been done to promote the site in the past, and various other factors. if you practice white hat link building methods and not use any spam techniques, your site should not go down in ranking even if google makes updates.
updates do not work properly if not licensed. Valid and feedback contented updates should only be effective.
Google updates results each day, so results can be different every time you check. The best way to keep results good - is keep on working with the site SEO every day and not leave it alone
I concur with sultan. That happened because of little bit renouncing in seo for your site have a peaceful day...
It could be a result of the over optimization update. You should make sure you did not over optimize your site for a certain phrase. Obviously you want to keep it as the title, but make sure the keyword density is only 1-2%. I never go over 1% these days out of fear that I will get punished for something. I also include at leas 20 LSI words.
i think there is something happening, some sites of my friends lost there ranking, and also two of my sites are no where? anyone noticed this?
might be your quality or work reduced, sometimes site not get backlinks at that time also keywords result got down
