I think proper planning and strategy is must for the SEO.

Nothing is more certain in the world of SEO than the fact that things will change over time. Rankings, search traffic, search algorithms and your website’s structure and content are all mutable. In order to maximize the value of your optimization efforts, it is important to know not only the nature of any given change, but when it occurred. At a fundamental level, it is impossible to make a relationship between cause and effect without knowing the sequence of events.

To this end, it is useful for SEO to plot relevant events and data against a timeline. This is especially true for in-house SEO efforts, as such efforts usually pertain to large, complex websites where there are numerous factors that may influence a site’s search performance over time. Such a method is also most likely to be successful in an in-house environment, where access to information is easier and there is a better chance at long-term continuity of data collection.
