There’s no comparison between SEO and PPC. Searching engine free ranking is far better and stable solution than PPC
PPC is fast and you can get ranking on immediate basis, but it’s too expensive and country oriented.
So for stable and reliable business always go for organic seo services. You can always hire any
reliable seo company for support.
Also I believe that visitors surfing results always prefer to see free search results before going into sponsored advertisements.
So in brief In beginning you can always start with PPC but goal should be attaining free organic ranks.
