While short-tail keywords are often searched more frequently, it is more difficult to rank for them on search engines. Targeting long-tail keywords, on the other hand, gives you a better chance of ranking higher (even on the first page) for queries specific to your products and services—and higher ranking means more traffic. Plus, as search engines and voice-to-text capabilities advance, people are using more specific phrases to search online. There are many free tools available to help you find keywords to target, such as Answer the Public.
Google recommends that all websites use https:// when possible. The hostname is where your website is hosted, commonly using the same domain name that you'd use for email. Google differentiates between the "www" and "non-www" version (for example, "www.example.com" or just "example.com"). When adding your website to Search Console, we recommend adding both http:// and https:// versions, as well as the "www" and "non-www" versions.
