If you are talking brand marketing than you can use search engine optimization as well as social media optimization for promotion. Actually, The world economy is now not in the best shape. Countries with their budgets and debts throws it to one or the other extreme. At the same time, one way or another it goes to small, medium, and big business, too. How to live in these rapidly changing market conditions?
The answer is, in fact, simple - work, work and work. Plus, sometimes adapt to the new rules of the game. If the world changes, should marketing change? Naturally, marketing budgets spent on various types of advertising, whether billboards, flyers or advertising on TV, of course a good thing. However, it seems to me that all these methods are good only for brand promotion or reminders about the company. You can also get help by the marketing agencies ie. RedLeos(.)com
