In comparing my January 2010 top search phrases hitting my site they are completely different than the December 2010/Jan 2011 phrases. I regulary check where I'm ranking and I'm still on first page for most of the same terms. Sometimes higher, sometimes lower...but ranking isn't much different. The one major difference is all the Google local links that now appear before the natural results. I'm wondering if this is greatly diluting traffic? Since my site is a photography site, another hypothesis is that people are very rapidly shifting away from web search to image search for photo sites. Last year my top search for "new york photos" brought 600 visits in January. By December is was 250, but I'm still on the first page. New terms which I know are coming from image search are all dominating now. For instance "xyz museum" or "xyz building". Those searches are people looking for specific images of that subject. I'm trying to determine whether the web traffic is being driven away, or if it's just shifting very quickly to image search. Overall traffic this months is down from last january about 20% so far. Thanks for any advice
