How does one who may sell SEO services in the future give away information without giving away too much information (and fearing that the client will run away with the proposed strategies and implement them himself/herself?)
That's a difficult situation and one I think a lot of people find themselves in. They are compelled to sell themselves by proposing a strategy but are afraid it can backfire. However, many clients who solicit the advice of SEO services are doing it because they cannot execute that detailed plan.
noel_x99 makes a great analogy that should make you feel a little bit better about providing that information:
Here's an example: We were recently at an arts festival watching an artist scultping a log with a chainsaw. Suppose that artist were to spend time with me explaining his technique and showing me how to do it - even what he was thinking when he applied his technique. Then suppose he handed me the chainsaw and told me to do it myself. I couldn't do it. Because I would lack the basic understanding of the skills of using a chainsaw. And even though he explained the technique...I couldn't do it. It's a combination art, technical ability, and experience that I don't have with a chainsaw.
That should alleviate those fears you have about giving away ideas (unless the client is well versed in this area of marketing). Most people can hear your suggestions but have no idea about how to execute. In the end, giving out more information does seem to show that you have the expertise and indicates that you're willing to help.
