Take a moment to think about your site content and how it can be broken up onto multiple pages. Remember each page shouldn't have too much text (500 words max).
Your website should be designed so that it makes sense to search engines and also people with low vision using screen reading software.
The page title is part of the page metadata (information about the page) and is visible to search engines and shows up on page tabs. It's often set in the web page settings in your web editor.
Use headings, starting with H1 to structure your content and tell people and search engines what's important.
