Once a website ranks on page one, ideally in the top 3 spots, we cannot guarantee it will remain there forever. This will depend on how competitive your search terms (what you want to rank for) are and whether other SEO agencies are trying to rank their clients above you.   Changes in the algorithms Google and Bing use to assess rankings can also take place sometime in the future. Google loves fresh content so it's always a good idea to tweak content over time, or add a few more links to keep the site active. Think of it like a car that needs a service every now and then to keep it in tip-top condition.
