Facebook Ads, Google Adwords, PPC (pay per click) Advertising, Search Engine Optimization (SEO),
Top social media marketing services typically are all the advertising options Facebook offers to advertisers for their clients and their own page on Facebook. In most cases, Google lends similar options with different benefits but a large majority of people use both services so it's not an "either-or" decision by any means. That said - other forms of advertising can still be cost-effective depending on the company in question and what they're expecting from you as a customer of theirs for whatever products/services they offer."
