if I have to choose between facebook ads and adwords it is certain that I will choose adwords, because when a visitor searches for what he wants with the help of google search they will find articles that match their purpose, there Google will display relevant ads so that visitors will most likely interested in advertising promotions that are aired, on the other hand google users have the most users among others so this option is a special choice if you want to use advertising services, I think this is the best option to be able to get visitors interested in the ads that we make it.
