Question
If a website doesn't have that much search volume for their primary keywords, is it worth spending money towards SEO if very few people will be searching these keywords to begin with?
Would the money be better spent on PPC or social media advertising instead?
Answer
It's difficult to provide a definitive answer without knowing the niche, but if you know PPC will work (which is keyword based) organic SEO should be more cost effective long term. Also, if search volumes are low, organic results should be easy to achieve and therefore less expensive.
