Hi Sean - your page Title shows up at the top of your browser. Keywords are never displayed. The Description shows up under your link in search listings.

Generally speaking the Title, and Description are important for SEO (Yahoo still looks at Keywords, but most search engines are phasing out their importance.) If SEO matters to you you should probably be using a custom domain with your Unbounce page.

Landing pages are not always an SEO exercise since they are often up for relatively short periods of time and have traffic driven to them in other ways.

Hope this answers your question!

Great answer. Thank you Jason
