@Jeff Amore just wanted to add my two cents.
I do both SEO and PPC for a living. You will hear all kinds of crazy stuff on this website, all with varying amounts of truth. Everyone is an expert these days. I would listen to @Sean Dolan and follow his response from above. Skip spending a single dollar on SEO until you learn more about your niche, the keywords that convert and search volume of each through an Adwords campaign. Hire a professional here, do not attempt to do this on your own. You want a high converting landing page, call tracking and conversion tracking that will send the data back to your campaign. Without this data, you're wasting your time.
To comment on what @Jeff B. added above, SEO is certainly not DOA. But if you were shady about SEO ever, you're going to take a beating sooner or later. If you practice honest white hat SEO, you wont have an issue. H1 tags, title and description tags are all still very important but need to be natural and not KEYWORD, KEYWORD, KEYWORD. Most importantly use honest, well written content that people will want to share. Unfortunately this means higher quality writers which also = more $$
Also, speaking to the graphics and pretty images, this actually does help you believe it or not. Attractive layouts, graphics, infographics and such help with sharing, natural link building and the overall "Dwell Time" which most certainly has an impact on your SEO.
