First of all, I want to point out that comparing Facebook Ads with Google AdWords isn't actually appropriate. Google is a search engine and Facebook is a social networking web site. The intent and engagement levels of the viewers are fully totally different for both the sites. In Google people actively seek for info and products and on Facebook they are wanting to join with their friends. Keeping Google Ads or Facebook PPC in thoughts, I want to give a quick abstract of what advantages do Facebook Ads have over Google AdWords;
Google AdWords is kind of costly even when you bid on low or medium reputation key phrases (and particularly keywords associated to purchasing online). Facebook is a brand new system wanting to leap into paid advertisement. If you hit the right niches, you could get visitors for a fraction of PPC pricing. Facebook ads are much more cost-effective and very good for small businesses attempting to achieve a presence online without a huge finances.
Visual help might be provided to your ad through this function. An picture is worth a thousand phrases and the power to point out photographs in advertisements is a big advantage Facebook has over Google AdWords. You can use photographs in Google AdWords by creating your own image banners but they don't convert too nicely. In Facebook advertisements, it's easy to addContent a small image along together with your text, which helps drawing attention of your target consumer. It can be good if you need to show images of your model or product. I imagine this is the most powerful function of Facebook advertisements.
