Hey kingsizexx you have the right idea, considering which product OP wants to be advertised, we can give the right call. If it is a site, then of course there is no way to go without seeking some answers from SEO guys. You got to know the minimal user requirements to fit the terms of TOP search engines like GOOGLE and ALEXA, also should optimize the weight of site in order for client to not struggle with opening your site lol. A friend of mine that works in SEO at WebsiteStrategies company has told me that they got monthly ton of clients but just few of them know the right ideas about SEO.
