Optimizing Your Meta Tags
What they look like:
"//meta name="description" content="This would be your description of what is on your page. Your most important keyword phrases should appear in this description.">"
meta name="keywords" content="keywords phrase 1, keyword phrase 2, keyword phrase 3, etc.">"
Where they belong:
The correct placement for both meta tags is between the head> and /head> tags within the HTML the makes up your page. Their order does not really matter, but most people usually place the description first then the keywords meta.
We recommend that your Keywords Meta not exceed 1024 characters including spaces.
We recommend that your Description Meta tag not exceed 250 characters including spaces.
