In the Internet, effectively advertise businesses focused on the country, region, city. But there remains a large chunk of small companies that can give significant infusions to the Internet business.
Many small businesses that are focused on serving the area. For example: gyms, home appliances repair, tire fitting, beauty salon, etc. etc. Now there is no sense for such enterprises to go online, except to register in thematic directories.
If the main advertising platforms make geo-targeting possible in districts of the city , then this will attract new participants in the Internet advertising market and add work to website builders.
