The Panda update has negatively affected legitimate ecommerce sites that use product descriptions from manufacturers
A clear solution for eCommerce sites effected by Panda is to use progressive content, flash or even html5 canvas to render the talking points which have been duplicated across nearly all other sites that sell the same product. These design changes can also improve sales rates as it draws the visitor to view these important elements.

Google, bing, yahoo all have image search engines. With careful consideration of images, for example info graphics, it is possible for sites to get visitors and clients from these searches.
Optimizing for image search has only a few variables; image name and URL, alt tag, page content near the image.
To SEO an image consider the keywords in these variables. Then consider how many different pages you can place (link to the image) the image on, places where it will be seen by many visitors. Can it be used on forums? Google places image? If the answer is yes then you can quickly give the image an importance for the keywords you desire. Most images on the internet are not well linked to.
A web page could be encoded in nothing but div and span tags. However, search engines do not process those types of pages very well. They like material to be marked with tags that identify the type of material e.g. Headlines, Paragraphs …
From a page design standpoint a time tag is the same as a span tag. But looking outside of the page itself it provides information to the outside world about that particular piece of data, page or article.
The simplest format is <time datetime=”2009-10-22″ pubdate>October 22, 2009</time> or <time datetime=”2009-10-22″ ></time>. An RSS type of format may also be used <time datetime=”2009-10-22T13:59:47-04:00″ pubdate> October 22, 2009 1:59pm EDT </time>
This information is very useful to researchers and greatly expands how search engines can offer up search results. Timeline searches are not exactly mainstream right now but that does not mean they should be ignored.
