I absolutely agree that we should only do what we can do well. We don't want to overwhelm ourselves or our clients. What we recommend and set up for them is going to depend on each individual client and their business.
For example, a B2B will more than likely get more bang for their buck from LinkedIn than a B2C. Not every social networking tool is for everybody. We need to find where their laser-targeted audience is hanging their hats most often, etc. That's where an initial analysis with our clients comes in.
Who are they wanting to target? What are they presently using? What is working? What isn't? What may work better? That type of information will help us focus.
We're setting them up for success and that means teaching them to effectively use what is going to help their business the most.
It's just amazing the amount of tools that exist right now to help us do all that!
