While we know you just want to be able to update your site's content without getting bogged down with technicalities, a basic understanding of HTML can go a long way to keeping your site looking consistent and performing at its best.
Listed below are some quick HTML tags that you'll find useful. You probably won't need to write them out in code form, but knowing what to look out for will definitely help you along the way.
Headings
<h1>, <h2>, <h3>, <h4>, <h5>, <h6>
Headings are used for titles and sub-titles on your page. If you think about a reference book, it will be grouped into chapters, then sections and probably sub-sections. Each will start with a heading, that will usually get more specific as you drill down into the content.
Headings on web page serve the same purpose, structuring your page content and allowing visitors (and that includes search engines) to scan your page to find the most relevant section for their needs. Headings are also an opportunity to use key search phrases on your page, as they tend to stand out more prominently than regular paragraph text.
Next time you need to add a title or a sub-title, remember to choose a heading option, rather than simply making your text bold.
Paragraphs
