A meta tag is an HTML tag containing information for search engines about a specific website. Meta tags contain keywords or phrases alerting search engines of a website's content to be included in search results for users requesting related information.
Keywords are ideas and topics that define what your content is about. In terms of SEO, they're the words and phrases that searchers enter into search engines, also called "search queries." If you boil everything on your page — all the images, video, copy, etc. — down to a simple words and phrases, those are your primary keywords.
As a website owner and content creator, you want the keywords on your page to be relevant to what people are searching for so they have a better chance of finding your content among the results.
Keywords are important because they are the linchpin between what people are searching for and the content you are providing to fill that need. Your goal in ranking on search engines is to drive organic traffic to your site from the search engine result pages (SERPs), and the keywords you choose to target (meaning, among other things, the ones you choose to include in your content) will determine what kind of traffic you get. If you own a golf shop, for example, you might want to rank for "new clubs" — but if you're not careful, you might end up attracting traffic that's interested in finding a new place to dance after dark.
Copywriting is the art and science of writing copy (words used on web pages, ads, promotional materials, etc.) that sells your product or service and convinces prospective customers to take action. In many ways, it's like hiring one salesman to reach all of your customers.
