Hi, we have some articles like this: http://www.schicksal.com/Orakel/Freitag-13 The main image has a width of 100% and a height of 100%. Today, I've discovered that GWT Instant Preview has some troubles with rendering the page. We have CSS rules to deliver the image with the right dimensions. If a bot like google is not sending any screen height / width we assume the screen size is 2560x1440. Does this harm the ranking of the page? (Content starts below the fold/image) What is a "default" screen size for google? How do they determine if something is "above the fold"? Any tips or ideas? Best wishes, Georg.

Hi, I've a calender page which changes every day. The main url is
/calendar For every day, there is another url: /calendar/2012/09/12
/calendar/2012/09/13
/calendar/2012/09/14 So, if the 13th september arrives, the content of the page 
/calendar/2012/09/13
will be shown at
/calendar So, it's duplicate content. What to do in this situation? a) Redirect from /calendar to /calendar/2012/09/13 with 301? (but the redirect changes the day after to  /calendar/2012/09/14) b) Redirect from /calendar to /calendar/2012/09/13 with 302 (but I will loose the link juice of /calendar?) c) Add a canonical tag at /calendar (which leads to /calendar/2012/09/13) - but I will loose the power of /calendar (?) - and it will change every day... Any ideas or other suggestions? Best wishes, Georg.

Hi girls + guys, a site of us were hit by a google update or a google penalty. We have lost 50% google traffic in one day (25th april, 2012). (Total visitors in average per day: 6k, yesterday: 3k) It's a german website, so I think google.de (germany) was updated. Our rankings in google.at (austria) are also affected, but it's not that bad as in google.de. We have not done any specific on page seo activities in the last two months. GWT doesn't have any message for us (no critical errors). After my first analyse I can say this: google has indexed 17k pages (thats fine) we are on 1st place with our domain name the last three days, the google traffic went up (+20%), but yesterday it was 50% below average (so -70%) last week we had a very good day, we had twice the traffic than normal, but this calmed down the following days we have lost number no. 1 places at two high traffic keywords. We had these no 1 rankings for years. We have been outranked by two of our competitors, but they have not done any onpage changes. We have lost a lot of positions at a lot of keywords. But there are also keywords which moved up. We have good content, useres are visiting 5 pages in average. No virus, no hacker (no hidden cloaking page) it's an old domain (2002) Lot of (good) inbound links Lot's of likes, g+. Good twitter activty. So, all in all I think it's more likely a ranking algo change than a penalty (a penalty for what reason?) My specific question(s): Is there any "check list" which could help me to find out the reason for this mess? What is the best strategy to regain the positions? New HTML code? New On page seo? (seomoz grades most of our important pages an A) Any idea would be appreciated! Best wishes,
Georg.
