Good or bad, has always been an individualistic perceptive judgment. However, when considering audience at large, crossing geographical, language and class barriers, good would be something that almost all of them should understand and appreciate. Good SEO copywriting that could be SEO web content or SEO articles should thus be lucid and simple to understand instead of flaunting the language skills.
Internet being the in-thing for most markets today, your website should have the aesthetics, tone and language (content-wise) that would suit most mindsets and more importantly, its SEO web content should be understood by the wide array of people. What is the use of drawing traffic from across the world when your website copy is written in Greek. Unless, of course, you are targeting only the Greek market.
Simplicity is the key to good SEO copywriting here and getting the message across without beating around the bush is imperative. Most people do not have the time to know why your products and services are the best in the world. They would rather spend their time in understanding, how your products and services can address their needs.
SEO or search engine optimization of course is a different ballgame altogether.
Uhh.. the complications - easy to read, simple SEO web content language, addressing the needs, SEO and then looking good. Your website seems to be a long way off from being on the path to path to glory.
