http://img.keyin.cn/2013_skin/2012_logo_index.gif (expiration not specified)
...
Avoid landing page redirects

Avoid landing page redirects for the following chain of redirected URLs.
http://keyin.cn/
...
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 65% of the final above-the-fold content could be rendered with the full HTML response.
