suppose i had top notch expert onpage seo work done on a local business website, would there need to be any upkeep with regard to the onpage stuff? (other than like if they change a phone number or something).
i guess the question is whether onpage is a continuous process or once its done its done.
lets say we are talking about a website for a business that is just there so when people search for a plumber they find the site.
offpage i would assume is continuous forever theoretically?
thanks in advance
