Twitter is everywhere, and that means your marketing efforts can be everywhere as well. We all follow our favorite celebrities, friends, and coworkers. But what do you do when you don't know how to get relevant followers for marketing purposes?
There are many different ways you can get this information. Now there are Twitter lists, directories, recommendation engines, search engines, and local searches. Any one of these can help you find potential customers for your affiliate marketing  offers.
In early 2009, Twitter started a list of “suggested users,” which was similar to recommended reads in a bookstore. Now, Twitter also gives you suggestions on who to follow based on your current list of followers and who you follow. This option is done through Twitter directly, not from a third party. Twitter also offers the ability to create and subscribe to lists of favorite users.
Third-party Twitter lists are another option that will help you find who you want to follow based on your search criteria. These lists are broken down into categories and subcategories (for example, Sports»Baseball»Boston Red Sox). One very popular Twitter list search engine is Listorious. There are many other Twitter lists, and as long as you know the topic you're interested in, you will find them very helpful.
Another way to help you find people to follow is through Twitter directories such as WeFollow. These directories provide you with statistical information about people you want to follow, such as their location, number of followers, and areas of interest. They break it down for you so that it will be easier for you to find who you are looking for.
Twitter recommendation engines like Mr. Tweet are another helpful resource. They provide you with a lot of information about the particular party you are looking for. Another thing this service does is gets the users involved by having them express who they recommend to follow, so you are also getting the users' input.
Twitter search engines are another tool that will help you find that targeted traffic. This works just like any other search engine, but since it deals with Twitter specifically, it will give you only Twitter results. They provide you with a lot of statistical information about the user which is great for SEM optimization. A good example of a Twitter search engine is Tweepi.
There is also a local way of doing your search through twitter local searches. For example if you live in Miami, FL and want to follow someone in your community, then this would be a great choice for you. LocaFollow is a great example if you are interested in doing a local search.
Twitter is big already but don't expect it to simmer down. It is only getting larger and more user-friendly. Some believe the search volume on Twitter will top the major search engines. People are joining every day, and the number of people to follow is obviously increasing as well. These suggestions will help you find potential customers and SEO opportunities.
