The content-type meta tag is necessary to declare your website's character set. It should be present on every page.

Leaving this out could impact how your page renders in the browsers. A few options are listed below, but your web designer should know what's best for your site.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

HTML defines six levels of headings. A heading element implies all the font changes, paragraph breaks before and after, and any white space necessary to render the heading.

The heading elements are <H1>, <H2>, <H3>, <H4>, <H5>, and <H6> with <H1> being the highest (or most important) level and <H6> the least. They are used to help users and search engines to read and understand text.

For example, they act as signposts for the readers and make it easier for people to understand what a post or page is about.

Headings also define which parts of your content are important, and show how they're interconnected.

They are one of the key signals, along with many others, used by Google's search algorithm.

Here are some heading tags best practices.
