Paid search marketing, also known as Paid Placement or Pay Per Click, lets advertisers pay to appear in search engine results for specific keywords or phrases. These listings can be bought from portals or search networks, where keywords have a cost-per-click fee. Major networks include Google Ads & Yahoo! Search Marketing, with others like Microsoft AdCenter also offering this service.
A good search engine marketing company let you choose relevant search terms, set up accounts, write ads, create landing pages, manage bidding and budgets & refine ads for better performance.
