If you’re starting with a simple site that just has a few pages, this may not seem all that important right now. But it’s still smart to plan out your site architecture in advance so you have a structure in place as you go. For most websites, your site architecture should have a pyramid structure. Your homepage is at the top, with the next most important pages (typically the ones that go on your main menu) right below that. Underneath those, you’ll add any subcategories and individual pages that fall within them.
To avoid competing against yourself, choose unique ones for each page this means your initial keyword research can help you gain an overall picture of the language to use when building your website, but it’s also good practice to choose a target keyword for each individual web page on your site.
Try to keep your title tag short google will only display 50-60 characters on the search engine results page and even less of the title tag will show up in the tab at the top of your browser. The title tag is part of the website Google looks at to learn what the page is about, which makes it another good spot to use your target keyword.
