Why should I continue SEO once I’ve gotten good rankings?

Achieving the rankings is only half the battle. Since the search engines are constantly evolving and updating their algorithms, your rankings can fluctuate from one day to the next. Maintaining current rankings is just as involved as getting new ones; it takes constant research, updates and testing to keep your URL ranking in the top positions. Discontinuing SEO after you’ve achieved rankings will result in a loss of rankings fairly quickly.
