Asking the right questions, is more important than having all the answers.
Knowing how to to get higher rankings in a Google search isn’t as important as asking, will it make any difference? It’s likely your time & effort would be better invested in creating effective ways to interact with your current customers, than spending your time looking for adhoc new ones via Google. If you build a rapport & trust with customers your already have, they will recommend you and talk about your products & services to their peers, which is far more powerful & effective than a high ranking in Google, will ever be.
Having answers is great, just make sure they’re answering the right questions.
