Once you’ve been on Twitter for a while, you’ll notice people will place you on public Twitter lists. Lists are generally categorized by a special interest or geographic location. For example, I might be on lists for “marketing experts,” “bloggers” or “business educators.” Find a relevant person to follow, and then dig into his or her lists. You’ll likely find a goldmine of interesting people to follow who will hopefully follow you back.
For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
But while you're maintaining the fun level on set, remain vigilant. It's your job to pay attention to the little things, like making sure all of the mics are on or noticing if the lighting changes. Record each section many times and have your talent play with inflections. When you think they've nailed the shot … get just one more. At this point, your talent is already on a roll, and options will help tremendously during editing.
