Which is the best - PPC or SEO?

[Davidwatson]

With a limited budget, I would focus on PPC. PPC is more likely to net conversions, especially in the short-term. SEO is a long-term strategy and one that you yourself can have a big impact on by reading up on it a bit and optimizing your site, creating a blog, etc. Also, as SEO is much more of an art than a science, no guarantee that the spend on SEO will be all that beneficial beyond what you can do on your own.
