Web images are akin to a double-edged sword with conflicting sides. One helps you fight but the other fights against you. Whereas they are important in increasing rankings on search engines and viewership by users they can be what makes users readily click on the back button without second thought.
The goal of SEO web design is to launch an eye-catching site that drives traffic. Both the internal workings of your SEO strategy and external workings of your web design require a certain level of expertise, although specialists who declare themselves experts in both the technical tidbits of SEO as well as the aesthetically appealing elements of web design are few and far between. SEO web design is more than making sure your code is optimized for the search engines but with the right combination of skills you can have all of the elements in place.
