Which advertising platform should a business start with?
Start with Google Ads when customers already search for what you sell, because search ads reach people at the moment of need and convert fastest. Start with Meta Ads when the product is visual, the audience can be defined by interest or life stage, or the business needs to create demand rather than capture it. Use LinkedIn Ads only for business-to-business offers where the job title of the buyer is the main qualifier, because its clicks cost the most.
GrossiWeb runs the two main platforms as separate services with their own pricing tables: Google Ads management and Meta Ads management. Most clients start with one and add the second once the first is profitable.
