Which of these are you using for your business?
The best one for your business is based upon who your ideal client is and where they are located. The fact is, you are not looking to market to the entire internet. As a service professional, you want to capture the attention of the local area that you serve. Social media should be there to help build and support your community, not to replace it.
Tag photos of your customers, invite them to share photos of recent projects and let social media keep your community connected.
