How do I improve my SERP? What is already on the page 1 to page down to a much under? What causes it?
hmm , it could be that your site has been filtered to your particular area, try using EN Google IPs and then keyword-search your site 72.14.235.99
You did not get a steady flow of 17000 visitors a day until jan 30. All along you were getting 6000 a day and for 2 weeks from 15 th Jan to 30 th Jan, you got a spike in traffic (Digg? stumbleupon?) and then it waned. Your average visitor count was 6000 a day. NOT 17000. If you can explain the spike, we can try to explain the fall. Alexa is'nt wrong entirely.
That's for sure, Alexa isn't wrong. We didn't get a spike. 95% of our traffic comes from Google Search when it was 17K. I guess reason is we renewed our web site end of December, and it takes time for Google to index our web site. While Google is indexing number of visitors increased day by day. There is no Social Bookmarking traffic ( digg, stumbleupon, etc.)
I also faced the same dileama. My site used to get close to 600+ visits from Google search. Now it's just around 80. I thought I was penalised but now it looks like so many is facing it recently. Same thing has happend to my Google images traffic (it actually dropped to 10-15 from 600+) earlier. But now its back and is double of what it usually was. So may be it is a problem with Google. I am waiting with my fingers crossed.
