Very important if you want the best from search engines is
Every page should have a title, it shows top left on the browser.
Insert after head.
Look at the following from my site and add as required.
<meta name="description" content="Xtal Home of Service, Family, and friends
Sale and wants service for family and friends.">
<meta name="keywords" content="Xtal, Brownen, Merryweather, Mereweather, Merewether, For Sale, Second Hand, Wants, Adds, Einstein Computer, Church for Sale,">
<title>The home of Xtal.</title>
All of the above helps a search engine rate the site.
Note the commas between words in the key words.
