@julian ~~

The key words of my site can not be identified by analytical tools. I checked the source and compare it with other sites
I found
<meta property="keywords" content="
should be
<meta name="keywords" content="

Is it a typo? If yes, how can I fix it?

att........

@julian you are right~~but it is the reality:( I wonder why the document.write doesn't work(if you have time to explain......)

@Giorgio-Chiodi Well, I am pretty a beginner.. I did see a footer.tpl in the Vanilla folder... So I feel strange that there isn't in the lavender... Sorry I typed the "lavender" as vanilla there.

@julian Thanks a lot :)!! I am using vanilla as the theme, but I didn't find "footer.tpl" in the template folder. Where is it?

@julian help~~

Any ad-hoc/hard-coded methods? I really need it...

is there any other method to add javascript code in the <header> or<footer>?? The widget doesn't works all the time. I can't even get certified by Alexa with the code they provided.

@frissdiegurke no error showed in log.

here is what I added:
<script type="text/javascript">
var _bdhmProtocol = (("https:" == document.location.protocol) ? " https://" : " http://");
document.write(unescape("%3Cscript src='" + _bdhmProtocol + "hm.baidu.com/h.js%3F0da233db09b6a0886cd3f9d1a52e64d8' type='text/javascript'%3E%3C/script%3E"));
</script>
