Which is best PPC or SEO for website promotion and why?
Both but it depends on your goals and time span for achieving them.
PPC is fast. You could make money by tomorrow - with the right offer, the right ads, the right keywords etc. Caution though, it can be expensive if you get it wrong. Make sure you set your daily budget at something you can life with.
SEO is a long term project - it may take 3 months or so to rank in the search results
