As I have been describing the Meta Descriptions, Meta Keywords and Meta Robots I referred to all of them as "tags."
The HTML language includes many variations of the "meta" code, each variant has a specific purpose. Some software companies will also come up with their one unique "meta tags" for your website. These unique tags may have a special software purpose, or they could be for tracking and analytics.
You will commonly hear people referring to their meta tags, for example, "You need to examine your meta tags to improve them." This example actually refers referring to your "meta description" tag.
If someone mentions "meta tags" and you don't know exactly which variation they are talking about, just stop and ask them. I can think of at least 15 different variations of meta tags.
Admittedly it's easier for me to generically say "meta tags" than to remember exactly what that "meta verify-something-or-other" tag is. But if you ask me, I'll go look it up.
