Here is an example of good metadata to create for your home page if you were a painter in the Greensboro, NC area. This is meeting all of Google's requirements while connecting with the user to urge them to click on the website:
PAGE TITLE
Your meta title is a brief and accurate description of your business. Make sure to include the main location your business is registered, what your main service is for that page, and your business name. This appears in both search results and open website browser tabs.
The optimal length is: 55-60 characters
Example: “Greensboro, NC Professional Painting Services | Zibster”
META DESCRIPTION
Your meta description should summarize what the page is about. Search engines use this to give users a brief summary of the page/website before they click on it, so finding a balance in writing for Google and users is important. Make sure to use the main keyword from your title and your main location, while also including some verbiage that shows users what sets you apart and makes them want to click to see more. Words like professional, certified, 15+ years of experience are great things to try and include if you have the space.
The optimal length is: 50-155 characters.
Example: “Interior & Exterior Professional Painting Services for all your Commercial & Residential contracting needs in Greensboro, Winston-Salem & surrounding areas.”
META KEYWORDS
Keywords and phrases should be unique, separated by commas, and relevant to the content of the page you are optimizing. You should use no more than 15 keyword phrases per page to avoid being penalized by Google.
