Internet Marketing for Micro Businesses Internet Articles | May 15, 2004

There are small businesses, and there are ?micro? businesses. Micro business is a term I use, for example, to distinguish a small nail salon employing 3 or 4 people
from a small manufacturing plant that employs 100 people. In conventional terms Marshon Lattimore Jersey , both are small businesses. In reality, and certainly when it comes to marketing, they are worlds apart.

The micro business is not alone, however. In aggregate terms, the total sales volume of micro businesses around the country may well exceed the the entire next rung of small businesses. Today Tre'Quan Smith Jersey , more and more micro businesses, most of which are local or regional in terms of sales and distribution, are going online with a website. It?s a logical move ? as more and more consumers search locally online, the micro business community needs to follow. But once they are online, how can they best promote themselves to their local audience?

The key point to remember is that most micro businesses Marcus Davenport Jersey , individually, are extremely limited in terms of time and money for online marketing. Realistically, a micro business has three options to consider: search engine optimization, paid-inclusion (including pay-per-click, or PPC) Michael Thomas Jersey , or some form of directory-type advertising, commonly called Internet Yellow Pages. (IYP). For most micro businesses, the IYP route is the only one that makes marketing sense.

The big lie on the Internet is that successful search engine optimization (SEO) is affordable. It?s not. It?s very expensive, and getting more so every day. It is obvious why this is so: with dozens, perhaps hundreds of websites in any given category all trying to optimize themselves for the top ten spots on Google Drew Brees Jersey , the prize goes to the ones with the biggest budgets, who are able to hire search engine optimization firms. And even then, playing the SEO game is dicey, as the following example shows: try searching on Google for ?house painter Atlanta.? Most, if not all of the results will do little to make your house the envy of suburban Atlanta. For house painters in that city Authentic Saints Hats , using SEO as a marketing tool would obviously be an expensive proposition.

So how about Adwords? They?re the paid Google ads next to the search results, and most of the Adwords advertisers on the above search (though not all) actually do paint houses in Atlanta. Here, the problem for many micro businesses will be the issues of budget, again, along with time and technical savvy. Certainly Authentic Saints T-Shirts , some small businesses will be able to manage a self-serve ad campaign (unless it?s on the incredibly complicated Overture network) ? but most probably won?t. They either don?t have time, or they?re not aware of the opportunity.
