Hello.

I have some simple questions about keywords / metatags.

1. Are they the same thing? If not, how do they differ?

2. Do you separate the words with a comma (wedding, cakes, Yosemite) or run them all together (Yosemite wedding cakes)?

3. Should they be one word long, or can you use two or more words in one meta tag? (Yosemite weddings, Yosemite wedding cakes) If the latter, do you separate the phrases with a comma, or do you put the phrases in quotes, or something else?

I read here that Google stopped using meta tags years ago. Is this still the case?

Thank you.
