Marketing can either slow or fast:

• Slow marketing relies on building relationships and shows results after months or a year e.g. blogging.
• Fast marketing relies on snap judgement and shows results soon after they are used e.g. advertising.

Consider having two separate marketing budgets Quarterly budget for fast marketing and yearly budget for slow marketing. But never be afraid to cut clearly failing marketing.

Most marketing channels can be used for both slow and fast marketing. It depends on what your aim is with the message and how it's presented.

Facebook update with a long content                 => slow marketing.
Facebook update with a sale offer                   => fast marketing.
Video how to install any security device on a door  => slow marketing.
Video commercial of your security device            => fast marketing.
