Despite what many marketers wish for, there is no magic potion to receiving instant results for your search engine optimization. At least, you should be leary of systems that promise instant success. I recently read this press release from Search Engine Trust. Although their service will likely help your rankings, it should be used with caution by coupling with other SEO practices such as writing compelling content, and developing an overall site that people want to link to naturally.
Effective SEO should be considered a marathon vs. a sprint. It takes time, and should be comprehensive!
