Because code's my site is htm5, so i has to be made in the files 1column.phtml, 2colums-left.phtml, 2colums-right.phtml, 3colums.phtm
<!DOCTYPE html>
<html lang="vi" xmlns:fb="
http://ogp.me/ns/fb#" xmlns="
http://www.w3.org/1999/xhtml" xml:lang="vi" version="HTML+RDFa 1.1">
and i don't change anything else
when i test on Google Structured Data Testing Tool, has 2 errors:
1.
In order to generate a preview with rich snippets, either price or review or availability needs to be present.
i deleted Stock Availability in my frontend, how to fix error?
2. This information will not appear as a rich snippet in search
results, because it is contained in a hidden HTML element. Except in
special circumstances, Google won't display content that is not visible
to the user. You should mark up the text that actually appears to your
users when they visit your web pages.
Please he me!thank you very much!
