i was trying to experiment something that i'm not sure if it work to some. but i might just want to confirm it to the members who knows well.

in the blogspot xml i 've seen these code and i've change the 'blog' with the keyword i'm trying to rank. will this work?

<head>
<b:include data='blog' name='all-head-content'/>

although it also gave a template error, i didn't mind it as i hope it work, can anyone tell me if this will work for the SEO of my site?
