Contextual advertising. An effective way to attract customers online. To advertise a product or service, the Google Adwords tool is used, which allows you to quickly respond to the action performed by the user – the search for the product by certain phrases or words. Contextual advertising is especially useful at the initial stages of business development, but requires considerable investment. Therefore, it is better to use the services of professionals for setting up contextual advertising, so as not to “drain” the budget.
