For example: apptree.cn, this station is my imitation style, I feel basically meet above said (as long as I can do), first of all, my CSS is placed at the top of the page, and is separated from the Web page, a separate CSS file, no page to turn, JavaScript at the bottom of the page And of course separate.

Because it is a virtual host of the relationship, I can not modify the settings on the server, but I feel from the Web page itself to modify and improve can maximize the rendering effect. And this optimization from the search engine included to see, the effect is very good.

If your station is slow to open, it will greatly reduce the efficiency of the search engine included, imagine, a spider index your page, wait a few 10 minutes have not opened, it will certainly think so: So broken station, open speed so slow, to the user experience will be very poor, I included it to make the search engine users bad, At the same time it wasted my time, I was busy, so spider away from you, your site is over.

Look at your Web page to meet the requirements of Yahoo does not meet, if not in line with, quickly to modify it.
