问题
I am trying to include extracted structured data in my webpages.
I included this for description:
<meta itemprop="description" content="my description" />
However I realised that there is already a normal meta description on the page:
<meta name="description" content="my description" />
Is it ok to leave both of them or it is really necessary to merge them together maybe like:
<meta itemprop="description" name="description" content="" />
回答1:
You should leave both of them. The Microdata Spec says:
If a meta element has an itemprop attribute, the name, http-equiv, and charset attributes must be omitted, and the content attribute must be present.
so it would be invalid to merge them.
