Use of Conditional Tags on certain pages on AMP HTML Blogger.
To create the current title meta tag, the code is just shorter. Considering that the conditional tags used to render the title (blog and article titles) on each page, have been shortened by Blogger.
The title meta tag is usually placed at the very top in HTML, which is between the and codes.
What we often encounter in most Blogger/Blogspot templates, the title meta tag is placed under the code along with other lines of meta tag code.
