Meta Tag are not display on some of pages I adding meta tag on my site, but some of page showing page title as a Meta title,  I want to change it with other name. 
But I don't know why it is not showing/Working on some of pages .

I observed that some page that connect with View those pages are only fail to add Meta tag. 

Anyone know what is issue. Why I'm fail to add meta tag.
Finally i found reason behind it.

I haven't call &lt;?php print render($page['content']); ?&gt;.

After adding it , it is working superb.
