SEO is a process, not a destination
You’ll never be done with your SEO work. You have to accept this when you begin any SEO project if want to avoid frustration, disappointment, or confusion. SEO isn’t something you can do just once and declare it done. Rather, SEO is one of the most complex areas of online marketing, and must be worked on regularly and treated as a process, testing and revising techniques. If you don’t do this, your SEO work may be effective only in the short term, or not at all.
