If you have a pretty limited search budget -- should you spend it on social PPC or Google PPC? Is one better than the other for marketing ?

i agree google ppc.

GOOGLE IS THE BEST,,,,, GOOGLE PLUS/ GLASS ,,,, THEY ARE MAKING IT MORE SPEEDY & EFFECTIVE

Google PPC could be the best option but it depends what is your product or service. SMM campaign can also work if your product is very interesting for social audience.

Google PPC no doubt on that.
